Introduction
Overview
The Multilin DGCC Capacitor Bank Controller is a microprocessor-based unit that belongs to the Distribution Grid Controller family, and is designed as a Capacitor Bank switch controller. This device is used for the control of pole-mounted and pad-mounted switched Capacitor Banks in electrical distribution networks. A Capacitor Bank is composed of three capacitors, used one per phase. The Bank can be connected to the line in wye or delta configuration. The Multilin DGCC Capacitor Bank Controller controls only one-stage Capacitor Banks. This means that a CLOSE command will switch the whole Capacitor Bank into the line.

Description of the Multilin DGCC Capacitor Bank Controller
The Multilin DGCC is designed as a Capacitor Bank switch controller. This device is used for the control of pole-mounted and pad-mounted switched capacitor banks in electrical distribution networks. A Capacitor Bank is composed of three capacitors - one per phase. The Bank can be connected to the line in wye or delta configuration. The Multilin DGCC controls only single-stage Capacitor Banks. This means that a CLOSE command will switch the whole Capacitor Bank into the line.MAIN FUNCTIONSThe Multilin DGCC provides two modes of operation:
• Manual Mode
• Automatic mode
In Manual mode, the Capacitor Bank is controlled by the user by means of OPEN and CLOSE menu commands. In Automatic mode, the Multilin DGCC manages the Capacitor Bank according to the parameters set up in the Season configuration.Up to four Season configurations are available in the Multilin DGCC . Each Season is programmed by indicating its start and end date using its own independent control parameters. Thus, different controls are programmed for certain time periods. For instance, in a certain season it may be better to control the Bank by KVar control while in another season - for instance in summer - it may be better to manage the Bank by Voltage control.In each season, one of the four main control methods can be selected. These are:
• Time schedule
• KVar
• Voltage
• Temperature
The main control is supervised by another override control if it is configured in Settings. The Override controls are:
• Voltage Override Ctrl
• Temperature Override Ctrl.
Time schedule ControlThe DGC controller switches the Bank according to a calendar/timetable schedule programmed by user. The time-of-day is indicated in the format HH:MM. Each day of the week can be independently programmed with one CLOSE time (when the Capacitor Bank is switched ON) and one OPEN time (when the Capacitor Bank is switched OFF).
KVar ControlIn this case, the DGC controls the Bank taking into account the Capacitor Bank size. The customer can adjust the opening and closing limits for reactive power. The Multilin DGCC controls reactive power by connecting and disconnecting the Capacitor Bank accordingly.Some operating situations are taken into account before and after closing the Bank, in order to ensure acceptable and safe performance. For example:

DESCRIPTION OF THE MULTILIN DGCC CAPACITOR BANK CONTROLLER CHAPTER 1: INTRODUCTION
1. If the change of voltage expected when the Capacitor Bank is closed, is higher than the voltage limits, the Multilin DGCC does not allow the insertion of the Capacitor Bank into the system.
2. If the Capacitor Bank is switched into the system and after a programmed period of time, there is no significant change in VARs, or there is a negative impact on KVAr level, the Multilin DGCC warns of these issues by generating an ALARM, and in some cases tripping the Capacitor Bank.
Voltage ControlWith this selection, Multilin DGCC controls the Capacitor Bank based on the measurement of the line voltage DFT of the power system. The Capacitor Bank is closed to the power system when the voltage is lower than the minimum threshold voltage programmed, while it is tripped from the system when the line voltage reaches the high voltage threshold.
Temperature ControlWhen temperature control is programmed during the actual season, the DGC controls the Capacitor Bank based on measurement of the ambient temperature by an external temperature sensor. Two different settings are provided: HI temperature and LO temperature. When the ambient temperature reaches the programmed HI Temperature Close, the Capacitor Bank is switched ON. It is released when the temperature falls below the HI Temperature Open setting. When the ambient temperature is lower than the programmed LO Temperature Close, the Capacitor Bank is switched ON and is released when the temperature is higher than the LO Temperature Open setting.
Override ControlThe Main Control set up in the specific season can be bypassed or otherwise supervised by override controls. In this way, better control of the Capacitor Bank is obtained.Override controls are:
• Temperature override
• Voltage Override
When the programmed Override limits are reached, the Override function takes control of the Bank, inhibiting the action of the Main control. When the Override measurement falls below the release limits, control again returns to Main control.
Protective Functions
• Reverse Power Detection
• Undervoltage Detection
• Daily max count limit
• Neutral Overcurrent

EXTERNAL POWER
The Multilin DGCC faceplate is equipped with a three-state switch for selection of Internal or External voltage. With the switch in External position, the sensing and power circuits are connected to external power binding post on the front panel. The unit can be tested using a 120 V RMS source with correct polarity applied to these terminals. Testing of the regulator can be accomplished by adjusting the amplitude of the external source. The switch disconnects all power from the unit if switched to External power with no power source applied to the front panel voltage terminals. The External Control Power binding posts allow application of a 120 V RMS nominal voltage to the unit for test purposes.The binding posts designated as VOLTAGE METER allow reading of the input voltage, for calibration purposes
Working with the KeypadThe display messages are organized into a Main Menu, pages, and sub-pages. There are four main menus labeled Actual Values, Quick Setup, Setpoints, and Maintenance. Pressing the MENU key followed by the MESSAGE key scrolls through the four Main Menu headers, which appear in sequence as follows:

Password security Password security is an optional feature of the Multilin DGCC which can be setup using the EnerVista DGCC Setup software. The password system has been designed to facilitate a hierarchy for centralized management. This is accomplished through a Master level access password which can be used for resetting lower level access passwords and higher level privileged operations. In cases where operational security is required as well as a central administrative authority then the use of the password system is highly encouraged. The feature robustness of this system requires it to be managed exclusively through the EnerVista setup software. This section describes how to perform the initial setup. For more details on the password security feature, refer to Chapter 6 - Password Security.
1. Multilin DGCC devices shipped from the factory are initially set with security disabled. If the password security feature is to be used, the user must first change the Master Reset Password from the initial Null setting. This can be done only over communications, not from the front panel keypad. The new Master Reset Password must be 8 to 10 characters in length, and must have minimum 2 letters and 2

2. Now that the Master Reset Password has been programmed, enter it again to log in to the Master Access level. The Master Level permits setup of the Remote and Local Passwords. If the Master Reset Password has been lost, record the Encrypted Key and contact the factory to have it decrypted.
3. With Master Level access, the user may disable password security altogether, or change the Master Reset Password.
4. The Master Access level allows programming of the Remote Setpoint and Remote Control passwords. These passwords are initially set to a Null value, and can only be set or changed from a remote user over RS485 communications. Remote Passwords must be 3 to 10 characters in length.
3–28 MULTILIN DGCC CAPACITOR BANK CONTROLLER – INSTRUCTION MANUAL
SOFTWARE SETUP CHAPTER 3: INTERFACES
5. Initial setup of the Local Setpoint and Local Control passwords requires the Master Access level. If Overwrite Local Passwords is set to YES, Local passwords can be changed remotely only (over RS485). If Overwrite Local Passwords is set to NO, Local Passwords can be changed locally only (over USB or keypad). If changing Local Passwords is permitted locally, the keypad user can only change the Local Passwords if they have been changed from the initial NULL value to a valid one. Local Passwords must be 3 to 10 characters in length.
6. If any Remote Password has never been set, that level will not be attainable except when logged in as the Master Level. The same logic applies to the Local Passwords.
7. When passwords have been set, the user will be prompted to enter the appropriate password depending on the interface being used (remote or local), and the nature of the change being made (setpoint or control). If the correct password is entered, the user is now logged into that access level over that interface only. The access level turns off after a period of 5 minutes of inactivity, if control power is cycled, or if the user enters an incorrect password.

A2 METERING CHAPTER 4: ACTUAL VALUES
The Multilin DGCC unit measures the RMS of the fundamental frequency component of the voltage and current inputs, and detects the system frequency using the connected voltage input. Based on the measured AC inputs, the unit calculates line current and line voltages, power and power factor, Total Harmonic Distortion (THD) and 2nd to 8th harmonics per input. All currents and voltages are recalculated four times per power system cycle at fundamental frequency. Harmonic measurements are fully calculated every 3.5 power system cycles. Line Current, Line Voltage and Line Compensated Voltage are filtered values used for the control algorithm. Integration is based on an IIR filter over the last 10 measurements. For abrupt changes in metering, higher than 2 X PKP, a quick update over these registers is made. Displayed metered quantities are updated approximately three (3) times per second for readability. The Multilin DGCC provides the following measurements and metered values:
• Phase-to-Ground Voltages (V)
• Phase-to-Phase Voltages (V)
• Line Voltage (V)
• Phase Currents (A)
• Line Current (A)
• Ground Current (A)
• 3-Phase Active power (kW)
• 3-Phase Reactive power (kvar)
• 3-Phase Apparent Power (kVA)
• Power Factor (Lag or Lead)
• 2nd to 8th harmonic in % – for the CB phase current
• 2nd to 8th harmonic in % – for the CB voltage
• THD in % – for the CB phase current
• THD in % – for the CB voltage.
The Single Phase/3 Phase DGC connection is chosen based on Order Code and VT Input:Single Phase connection applies to the Multilin DGCC with one of the following configurations:
• IO_H card installed
• IO_A card installed and the VT Input programmed to Line-To-Line or Line-To-Ground.
Three Phase connection applies only to Multilin DGCC with the configuration:
• IO_A card installed and the VT Input programmed to Wye or Delta.
When a single phase connection is chosen, Voltage and Current inputs correspond to the Phase A inputs.By scrolling the Up/Down keys the unit shows, one-by-one, all metered values as follows:

Power calculationWhen Multilin DGCC is connected to all three-phase currents and voltages, the three-phase power is calculated as a sum of the three individual phase power quantities.When the Multilin DGCC is connected to only one current and one voltage input, the three-phase power is calculated assuming balanced system, i.e. the computed single-phase power is multiplied by 3. The following table shows the three-phase power computation for each combination of voltage and current input, programmable under the Voltage and Current Sensing setup menus:

ClockThe Multilin DGCC has an internal real time clock that performs time stamping for various features such as the event and transient recorders. Time synchronization priority uses Modbus or DNP commands as follows:Synchronization commands are all eventually translated into a MODBUS function, and as such are blocked from the MODBUS layer as required.There is no prioritization amongst synchronization commands. A synchronization command issued from DNP for example, can be directly followed by another from MODBUS, for example.PATH: SETPOINTS > S1 PRODUCT SETUP > CLOCK

With DLS Enabled, the main CPU has to maintain the information regarding AV.m_DaylightSavingsActive, because it is necessary in the comms CPU to translate from localtime to UTC in 61850 protocol. In addition, if SNTP is enabled, the main CPU will receive UTC time from comms CPU and it needs to apply this in order to pass it to localtime.
Without any other synchronization, DLS correction is applied only at 0200 hours on daylight saving months.

Password securityPassword security features are designed into the relay to provide protection against unauthorized setpoint changes and control. The relay has programmable passwords for both Local and Remote access, which can be used to allow setpoint changes and command execution from both the front panel and the communications ports. These passwords consist of 3 to 10 alphanumeric characters. The Local and the Remote passwords are initially set after entering in a Master Reset Password (MRP). The Master Reset Password (MRP) is set to “NULL” when the relay is shipped from the factory. When the MRP is programmed to “NULL” all password security is disabled.. The remote user may choose to allow the local user to change the local passwords.Each interface (RS485, USB, and front panel keypad) is independent of one another, meaning that enabling setpoint access on one interface does not enable access for any of the other interfaces (i.e., the password must be explicitly entered via the interface from which access is desired).The EnerVista DGCC Setup software incorporates a facility for programming the relay’s passwords as well as enabling/disabling setpoint access. For example, when an attempt is made to modify a setpoint but access is restricted, the program will prompt the user to enter the password and send it to the relay before the setpoint can actually be written to the relay. If a SCADA system is used for relay programming, it is up to the programmer to incorporate appropriate security for the application.Aside from being logged out of security, which allows the user to read setpoints and actual values only, three levels of security access are provided: Setpoint Level, Control Level, and Master Level. The Setpoint and Control Levels can be attained either locally using the Local passwords (USB port and keypad), or remotely using the Remote passwords (RS485 port). The user can have either Setpoint or Control Level active, but not both simultaneously from the same interface. The Master Level is used for setting and resetting of passwords, and includes all Setpoint and Control Level access rights. The Master Level cannot be attained from the keypad. The Master Reset Password must be 8 to 10 characters in length, and must contain at least 2 letters and 2 numbers. The Master Level can define whether the local user is permitted to change Local Passwords without having to enter the Master Level. The Master Reset Password is encrypted, and is not viewable from the keypad. If the Master Reset Password is lost, the user should contact the factory to decrypt the Master Reset Password.After password entry, the access level is maintained until a period of 5 minutes of inactivity has elapsed, after which the password must be re-entered. A power-loss or entering in the wrong password will log the user out of security.Further definition of the access levels is described as follows:SETPOINT LEVEL

CommunicationsFigure 2: Main Communications menu
RS485 interface The Multilin DGCC is equipped with one serial RS485 communication port. The RS485 port has settings for baud rate and parity. It is important that these parameters agree with the settings used on the computer or other equipment that is connected to these ports. This port may be connected to a computer running the EnerVista DGCC Setup software. This software can download and upload setting files, view measured parameters, and upgrade the device firmware. A maximum of 32 -series devices can be daisy-chained and connected to a DCS, PLC, or PC using the RS485 port.Select the Settings > Communications > Serial Ports menu item in the program, or the SETPOINTS > S1 PRODUCT SETUP > COMMUNICATIONS > RS485 path on the display, to configure the serial port.

Modbus The Modicon Modbus protocol is supported by the Multilin DGCC Capacitor Bank Controller . Modbus is available via the RS485 serial link (Modbus RTU). The always acts as a slave device, meaning that it never initiates communications; it only listens and responds to requests issued by a master device. A subset of the Modbus protocol format is supported that allows extensive monitoring, programming, and control functions using read and write register commands. Refer to the Multilin DGCC Communications Guide for additional details on the Modbus protocol and the Modbus memory map.The Modbus server can simultaneously support two clients over serial RS485. The server is capable of reporting any indication or measurement and operating any output present in the device. A user-configurable input and output map is also implemented.The operates as a Modbus slave device onlySelect the Settings > Communications > Modbus > Protocol menu item in software, or the SETPOINTS > S1 PRODUCT SETUP > COMMUNICATIONS > MODBUS PROTOCOL path to set up the modbus protocol as shown below.

MODBUS SLAVE ADDRESS
Range: 1 to 254 in steps of 1Default: 254
This setting specifies the Modbus slave address . Each device must have a unique address from 1 to 254. Address 0 is the broadcast address to which all Modbus slave devices listen. Addresses do not have to be sequential, but no two devices can have the same address or conflicts resulting in errors will occur. Generally, each device added to the link should use the next higher address starting at 1.

The Multilin DGCC can be connected to any available pair of voltage and current inputs, or to three-phase currents and voltage inputs, all programmable through the current and voltage sensing menus. During normal loading conditions the three phase currents and voltages are well balanced. The power computation from the Multilin DGCC connected to a single-phase current and single-phase voltage is calculated by extrapolating the single-phase power to a three-phase power measurement. The following AC inputs need be configured:

Capacitor Bank switchSwitch State DetectionBoth the normally open and the normally closed auxiliary contacts of the Capacitor Bank switch or breaker are used in order to assert the actual position. The Capacitor Bank CLOSED/OPEN state can be also detected by using one auxiliary contact, either 52a or 52b.The diagram below shows how Capacitor Bank status is detected using either the two auxiliary contacts (preferred), or one auxiliary contact. However the Capacitor Bank switch discrepancy alarm is produced only when both auxiliary contacts, 52a, and 52b, are used for status detection. Capacitor Bank switch detection is designed to assert two extra output operands: Switch Alarm (auxiliary contact discrepancy), and Block Switching Operation. Operation of Capacitor Bank switch detection is summarized in the following tables: Table 1: Switch Auxiliary Contacts and Switch Operation, and TABLE 2: Switch monitoring logic with both 52a and 52b contacts configured. There are also two diagrams depicting this element: FIGURE 8: Timing Diagram of the Cap Bank Switch Monitoring Logic, and FIGURE 9: Cap Bank Switch Monitoring Logic.The Capacitor Bank switch alarm flag “CB SW ALARM”, is asserted after a settable time delay if the auxiliary contacts of the switch do not match (open-open, closed-closed instead of open-closed or closed-open) yielding an undefined Capacitor Bank switch position. The operand may be used to block selected functions per the user’s choice. The operand may be reset manually or remotely via the Resetting Input operand.

MULTILIN DGCC CAPACITOR BANK CONTROLLER – INSTRUCTION MANUAL 5–23
General controlThe Switch Control feature has a programmable menu where the user can set the criteria for OPEN and CLOSE commands to the installed Capacitor Bank switch. The Multilin DGCC has one dedicated output relay for the OPEN command and another for the CLOSE command. Depending on ordered controller, the Multilin DGCC may have a number of other auxiliary output relays that can be programmed for close/open logic as well. The logic diagrams below show how the OPEN and CLOSE commands are individually generated.
MODES OF OPERATIONRemote/Local ModeThe REMOTE/LOCAL pushbutton toggles between REMOTE and LOCAL mode of operation. Each of the two modes is associated with a LED to show the selection. This selection has absolute priority and it can be made only by operating the REMOTE/LOCAL pushbutton.
Automatic, Manual, or OFF ModeThe AUTO/OFF/MANUAL pushbutton toggles between AUTO, OFF, or MANUAL modes of operation. The AUTO and MANUAL modes are associated with a corresponding LED, which turns on upon mode selection. When the OFF position is selected, both of these LEDs are off.The controller mode can be selected from the faceplate pushbuttons or from a remote location. The SCADA user has read-only access at all times, regardless of the mode selected. However, issuing commands and selecting AUTO/OFF/MANUAL modes via SCADA is restricted, depending on the selection as shown in the Controller Modes table below.
Table 3: Controller Modes
In Manual mode, the Multilin DGCC controls the switch by responding to manually performed commands from the faceplate OPEN and CLOSE pushbuttons. In Automatic mode, the decision to send a Switch Open or Close command will be made by the currently active control element.In both modes the Multilin DGCC controller sends either an Open or a Close command to the switch using two digital outputs: RLY 1 and RLY 2.In Remote mode, selected when in AUTO mode, the switch can be controlled by either the Open/ Close commands sent via communications, or by asserting inputs configured in the settings > S4 Controls > Remote Control menu: REMOTE OPEN and REMOTE CLOSE. Remote control overrides automatic control. After the remote operation is performed, the controller reverts back to automatic mode.

Block Auto mode from Communications (COMM BLOCK AUTO)Auto mode can be blocked remotely by asserting the command COMM BLOCK AUTO via communications. This can only be done using the EnerVista DGCC Setup program while in Remote control. In this case the switch can be controlled only remotely. This command is not visible on the HMI.
Save Block Auto from Communications (SAVE COMM BLK AUTO)While in Remote mode, the user can decide to keep the Auto mode blocked during a loss of communication or loss of power to the Multilin DGCC , by setting the command SAVE COMM BLK AUTO to “Enabled”. This will keep the Auto mode blocked after communication or power to the Multilin DGCC has been restored.
Unblock Auto mode from Communications (COMM UNBLOCK AUTO)Both the COMM BLOCK AUTO and the SAVE COMM BLK AUTO selections will reset upon issuing a COMM UNBLOCK AUTO command. This command is not visible on the HMI.
NOTE
NOTE: The DGC controller applies a 5-minute reclose blocking time after the Capacitor Bank is detected open. Closing of the Capacitor Bank is blocked during that time.
NOTE
NOTE: The DGC controller applies a 60-second time delay when switching from MANUAL to AUTO/REMOTE mode, to allow the operator to step away from the Capacitor Bank.

This setting specifies the minimum variation of Kvar expected when the Capacitor Bank is switched into the system. The Minimum Delta Kvars should be entered as a percentage of the 3PH BANK SIZE setting.
CHAPTER 5: SETPOINTS S3 CAPACITOR BANK CONTROL
MULTILIN DGCC CAPACITOR BANK CONTROLLER – INSTRUCTION MANUAL 5–25
When the Capacitor Bank is inserted into the system, a decrement of reactive power is expected. If after the insertion of the Capacitor Bank, the measured Delta Kvars is below the selected percentage of the 3PH BANK SIZE setting, or on the other hand, an increment is produced, the SWITCHING TROUBLE alarm will be triggered. However, if a negative power flow condition has been detected, the setting of this alarm will be blocked.
MINIMUM VOLTAGE
Range: 30 to 200 V in steps of 1 VDefault: 100 V
This is the voltage below which automatic control will not operate the Capacitor Bank switch. This function is used to prevent damage to the switch during brownout conditions.
REVERSE POWER PKP
Range: 1 to 1000 KW in steps of 1 KWDefault: 20 KW
If the Multilin DGCC is properly connected, the current transformer is located on the source side. Since the energy is flowing from the source side to the load side, the measured active power is positive.
If there is an alternative power source connected to the grid on the load side, the overall energy flow may reverse its direction. The Multilin DGCC will then measure negative active power. Under this condition, the Kvar measurement is not reliable.
This setting defines the pickup level for detecting a reverse power condition. If the absolute value of the negative active power measured by the Multilin DGCC is maintained higher than this value for a period of time programmed in the ‘Reverse Power Delay’ setting, a “Reverse Power Flow” flag will be set.
The operator can decide to block the operations of the Capacitor Bank switch if reverse power has been detected. (See Season Control setup.)
REVERSE POWER DLY
Range: 0 to 3600 s in steps of 1 sDefault: 10 s
This setting specifies the time during which the absolute value of the reverse power must be higher than the REVERSE POWER PKP level, in order to generate a reverse power condition.
MAX CLOSE/DAY
Range: 1 to 20 in steps of 1Default: 5
This setting is programmed with the maximum number of closing operations allowed during 1 day. If this number is reached, the automatic close commands are inhibited until the next calendar day, and an alarm is generated. The manual close operation is not blocked.
Although the alarm has been active, the automatic controls will continue to work and generate their own events.
MAX TOTAL
Range: Off, 1 to 10000 in steps of 1Default: 10000
This setting is programmed with the total of the maximum number of closing operations. If this number is reached, the automatic close commands are inhibited until the counters are cleared, and an alarm is generated. The manual close operation is not blocked.
5–26 MULTILIN DGCC CAPACITOR BANK CONTROLLER – INSTRUCTION MANUAL
S3 CAPACITOR BANK CONTROL CHAPTER 5: SETPOINTS
Although the alarm has been active, the automatic controls will continue to work and generate their own events.
MANUAL OP DELAY
Range: 0 to 3600 s in steps of 1 sDefault: 30 s
This is the amount of time that has to expire before executing a CLOSE command in manual mode. This setting prevents the operator from closing the Capacitor Bank instantly, and allows him to move away from the Capacitor Bank before the command is executed.
The internal variable TimeToOperate contains the time remaining before the Capacitor Bank is switched on to, or off from, the power system. This time is visible to the operator on the front face display.
When the operation is finished, a self-reset target message and event is displayed, along with the new CB state (OPEN or CLOSED).
This setting can be used for blocking the Capacitor Bank CLOSE command, when the selected input is activated.
CB SW FAIL BLOCK
Range: Disabled, EnabledDefault: Disabled
When this variable is set to “Disabled,” OPEN and CLOSE Capacitor Bank commands will not be affected by the status of the Capacitor Bank switch FAIL flag. When this variable is set to “Enabled,” and the Capacitor Bank switch FAIL flag is asserted, both OPEN and CLOSE Capacitor Bank commands will be blocked. The Capacitor Bank switch FAIL flag turns ON when the status of the Capacitor Bank switch is neither OPEN nor CLOSED.

5–30 MULTILIN DGCC CAPACITOR BANK CONTROLLER – INSTRUCTION MANUAL
S3 CAPACITOR BANK CONTROL CHAPTER 5: SETPOINTS
This assumption is true when the current is flowing for the main source side of the system to the load side. On the other hand, if the power is flowing in the reverse direction, the change in the reactive power after the Capacitor Bank is inserted into the system, cannot be measured directly by the DGC relay. So in this situation the expected change in reactive power cannot be used to detect a CB switching problem.
Delta voltage & Delta reactive power calculation:The Delta voltage and Delta reactive power are calculated when there is a difference in voltage and/or reactive power, when the Capacitor Bank is passed from the OPEN to the CLOSE state. When the Capacitor Bank is opened, the DGC relay takes a line voltage and reactive power measurement during each power system cycle. The last 10 measurements are stored in an internal buffer.Once a Capacitor Bank CLOSE condition is detected, the DGC waits 1 second to leave time for the measurement to be stabilised, after which 10 new voltage and reactive power measurements are taken. Then the delta voltage and reactive power are calculated based on the difference between the two integrated values. As Delta voltage is based on the secondary line voltage measurement, the Delta Voltage average setpoint has to be programmed using the Delta Voltage average expected at the insertion of the Capacitor Bank, as measured at the VT secondary port.On the other hand, because the size of the Capacitor Bank has to be set in KVArs, the Delta reactive power is calculated using primary values.

5–32 MULTILIN DGCC CAPACITOR BANK CONTROLLER – INSTRUCTION MANUAL
S3 CAPACITOR BANK CONTROL CHAPTER 5: SETPOINTS
Season controlThe DGC can be programmed to operate in up to four different season, with each season having its own control mode. A season is defined as a block of time with a start date and an end date specified by month and day. This capability provides to the user to select different control modes depending on time of year. This is useful when there are different changes in feeder conditions throughout the year.When an override control operation is selected, the main control mode is supervised by the second control selected.The override control can be:
• Voltage Override
• Temperature Override.
Thus, the DGC will operate the cap Bank based on the override control parameter whenever the pickup overrides limits have been exceeded. When the override measurement value drops lower than the dropout overrides limits, the main control takes the control of the bank switch it on or off based on the main control parameters.PATH: S4 CONTROLS > SEASON
START DATE #END DATE #
Range: Off, Jan 01 to Dec 31 in steps of 1dayDefault: Off
The Start and End dates of the season are programmed in these registers. The season must be programmed in chronological order and there are not allowed overlaps segments.
The DGC does not prevent poor parameter configuration. If a discrepancy is present in a setting, the DGC will avoid using such a setting.
The end of the previous season programmed always has to be higher than the start of the predecessor season.
In case of configuration error, an alarm will be provided.
MAIN # CONTROL
Range: Voltage Ctrl, KVAr Ctrl, Temp Ctrl, Time Ctrl, No-OPDefault: No-OP
The main automatic mode control is programmed in this register. There is up to five control modes:
Voltage Ctrl – The main control of the capacitor bank is made by the voltage measured at the line. The main voltage ctrl could be override by the temperature control as is explained in the Voltage control Mode specification.
KVAr Ctrl – The main control of the capacitor bank is made by the Reactive power measured at the line. This control could be override by the temperature and the voltage control as is explained in the KVAr control Mode specification.
Temp Ctrl – The main control of the capacitor bank is based on the ambient temperature measured by a temp sensor. This control could be override by the Voltage control as is explained in the Temperature control Mode specification.
Time Ctrl - The capacitor bank is automatically controlled by a timetable based on the day of the week. The cap bank is switched on and off based on a time schedule programmed by customer. This control can be supervised by voltage and temperature override control.
No-OP - The capacitor bank is always switched off when the control is in automatic mode.
CHAPTER 5: SETPOINTS S3 CAPACITOR BANK CONTROL
MULTILIN DGCC CAPACITOR BANK CONTROLLER – INSTRUCTION MANUAL 5–33
REVERSE # POWER
Range: Ignore, Inhibit, TripDefault: Ignore
Sometimes when a reverse condition is detected, the capacitor bank should be switched off from the system because the conditions have been changed.
This setpoint warns of this issue and generates a sudden trip of the cap bank, in such a situation, if ‘Trip’ is programmed.
When the Inhibit option is selected, the automatic control is blocked during the time during which the reverse power condition is maintained.
Time control scheduleThe DGC controller switches the Capacitor Bank according to a calendar/timetable schedule programmed by the user. Each day of the week can be programmed with one closing time (when the Capacitor Bank is switched on) and one opening time. It is not possible to select a different timetable for each week. WEEKLY CALENDARWeek Calendar Schedule:
PATH: SETPOINTS > S3 TIME CTRL SCHEDLE > WEEK TIME CTRL
DAY CLOSE
Range: 00:00 to 23:59 Default: Off
This setting defines at what time the Capacitor Bank will be switched on (connected to the power distribution system). The Capacitor Bank will stay connected to the power system until the Bank open time is reached.
DAY OPEN
Range: 00:00 to 23:59Default: Off
This setting defines at what time the Capacitor Bank will be switched off (disconnected from the distribution power system).
NOTE
NOTE: If the Open Time is set to an earlier setpoint than the Close Time, the Bank will close at the Bank close time programmed, and stay closed until the next Open Time - programmed for the next day.
In addition to the above, the DGC stores a full-year calendar with holidays or special days when the Capacitor Bank has to be switch off. The holidays can be split in two groups:
• Perpetual Calendar
• Vacation Calendar
These are as follows:
Day Bank Closing Time Bank Opening Time
Sunday 10:00 17:00
Monday 08:00 18:00
Tuesday 08:00 18:00

VAR controlThe DGC controls the Capacitor Bank based on the measurement of the reactive power of the power system. This function uses the reactive power calculated over the three phases. The General Settings documentation offers the ways to calculate the reactive power based on different types of connection.As the reactive power characteristic of the Capacitor Banks are given relative to the fundamental frequency of the system, the reactive power of the system should be calculated at the fundamental frequency. To select the Capacitor Bank switch in and switch out parameters, a rule-of-thumb that can be applied in most situations is to use a bank size that is two-thirds of the value needed to reduce the peak load VAr’s to zero.The setpoints associated with this characteristic are:PATH: SETPOINTS > S3 CAPACITOR BANK CONTROL > VAR CONTROL
3PH SWITCH-IN
Range: -10000 to +10000 KVAr in steps of 1 KVArDefault: 500 KVAr
This setting specifies the VAR level at which the Capacitor Bank switches in. The reactive power has to be above this value for the period of time programmed in the ‘VAR Time Delay’ setpoint before the bank will switch in.
3PH SWITCH-OUT
Range: -10000 to +10000 KVAr in steps of 1 KVArDefault: -500 KVAr
This setting specifies the VAR level at which the Capacitor Bank switches out. The reactive power of the line has to be below this value for the period of time programmed in the ‘VAR Time Delay’ setpoint before the bank will switch out.
VAR TIME DELAY
Range: 0 to 3600 s in steps of 1 sDefault: 30 s
This setting specifies the time the VAR measurement has to be maintained above/below the Phase KVAR Switch In/Switch Out level before switching the Capacitor Bank.
If Override Control is selected, the KVAr control (main control) will be supervised by this element.
When voltage override is programmed, the activation or deactivation of the Capacitor Bank is controlled by voltage measurement. If the voltage is higher/lower than the pickup override limits, the Capacitor Bank is automatically switched out of the power distribution network.
5–36 MULTILIN DGCC CAPACITOR BANK CONTROLLER – INSTRUCTION MANUAL
S3 CAPACITOR BANK CONTROL CHAPTER 5: SETPOINTS
With the temperature override programmed, the activation or deactivation of the Capacitor Bank is controlled by the ambient temperature measurement. If the ambient temperature is higher/lower than the pickup override limits the Capacitor Bank is automatically switched into the power distribution network.
Once the dropout limits are reached, the override control releases control to the main mode control.
See Override function for more details.
Voltage controlIf, in automatic mode, the voltage control mode is programmed in the actual season, the DGC will control the Capacitor Bank based on measurement of the DFT line voltage of the power system. If several line voltages are available, the line voltage reference will be programmed in the General settings.The setpoints associated with this characteristic are:PATH: SETPOINTS > S3 CAPACITOR BANK CONTROL > VOLTAGE CONTROL
HI VOLTAGE TRIP
Range: 60 to 250 V in steps of 1 VDefault: 120 V
This setting specifies the voltage high limit at which the Capacitor Bank will be switched out. The voltage level must be maintained higher than than this setpoint for a period of time - “Voltage Time Delay” - before the Bank will switch out.
LO VOLTAGE CLOSE
Range: 60 to 250 V in steps of 1 VDefault: 80 V
This setting specifies the voltage low limit at which the Capacitor Bank will be switched in. The voltage level must be maintained lower than this setpoint for a period of time - “Voltage Time Delay” - before the bank will switch into the power system.
VOLTAGE TIME DLY
Range: 0 to 3600 s in steps of 1 sDefault: 30 s
This setting specifies the time the VAR measurement has to be maintained above/below the high/low voltage level before switching the Capacitor Bank.
OVERRIDE CONTROL
Range: Disabled, TemperatureDefault: Disabled
If Override Control is selected, the main control (voltage control) will be supervised by this element.
With the Temperature Override programmed, the activation or deactivation of the Capacitor Bank is controlled by the Ambient Temperature measurement. If the ambient temperature is higher or lower than the pickup override limits, the Capacitor Bank will automatically switch into the power distribution system.
Once the temperature dropout limits are reached, the voltage control will take over again.
See Override function for more details about this functionality.
NOTE
NOTE: The VOLTAGE TIME DLY will not work properly if set to a time shorter than 10 seconds.

NOTE
NOTE: If the difference between HI and LO voltage programmed is less than the DELTA V AVERAGE from the General settings, the ALARM “Wrong voltage levels programmed” will be generated.
Temperature controlIf in Automatic mode the Temperature Control mode is programmed in the actual season, the DGC will control the Capacitor Bank based on the ambient temperature as measured by a temperature sensor. Control can be programmed to operate the Capacitor Bank in both directions.The settings associated with this are as follows:PATH: SETPOINTS > S3 CAPACITOR BANK CONTROL > TEMPERATURE CONTROL
HI TEMP BANK CLOSE
Range: -20° to 60°C in steps of 1°CDefault: 30°C
This setting specifies the temperature level in degrees Celsius, at which the capacitor bank will be closed. The actual temperature must be maintained higher than this value for a period of time longer than the “Temperature Time Delay” before the bank will be closed.
HI TEMP BANK OPEN
Range: -20° to 60°C in steps of 1°CDefault: 20°C
This setting specifies the temperature level in degrees Celsius, at which the Capacitor Bank will be opened. The actual temperature must be maintained lower than this value for a period of time longer than the “Temperature Time Delay” before the bank will be opened.
LO TEMP BANK CLOSE
Range: -20° to 60°C in steps of 1°CDefault: -1°C
This setting specifies the temperature level in degrees Celsius, at which the Capacitor Bank will be closed. The actual temperature must be maintained lower than this value for a period of time longer than the “Temperature Time Delay” before the bank will be closed.
LO TEMP BANK OPEN
Range: -20° to 60°C in steps of 1°CDefault: 5°C
This setting specifies the temperature level in degrees Celsius, at which the Capacitor Bank will be opened. The actual temperature must be maintained higher than this value for a period of time longer than the “Temperature Time Delay” before the bank will be opened.
TEMP TIME DLY
Range: 0 to 3600 s in steps of 1 sDefault: 30 s
This setting specifies the time for which the Temperature measurement has to be maintained above/below the HI/LO Temp level before the Capacitor Bank switch will operate.

OVERRIDE CONTROL
Range: Disabled, VoltageDefault: Disabled
If Override Control is selected, the main control (Temperature control) will be supervised by this element.
NOTE
NOTE: If HI TEMP BANK OPEN is set lower than LO TEMP BANK OPEN the "Unit Config Error" Temp Ctrl Alarm will be generated.
With the Voltage Override programmed, the activation or deactivation of the Capacitor Bank is controlled by voltage measurement. If the voltage is lower than the pickup override limit the Capacitor Bank is automatically switched OFF from the power distribution network.Once the voltage dropout limit is reached, the temperature control will take over again.See Override function for more details about this functionality.
Override controlThe Override control mode provides a way to supervise the automatic main control mode programmed in the actual season. The season setting determines which is the main control mode governing the Capacitor Bank. When an Override control is allowed , the DGC operates the Capacitor Bank based on the Override control parameter whenever the pickup override limits have been exceeded. When the Override measurement value falls below the dropout override limits, the Override control releases control to the main control mode. The Override control can be:
• Voltage Override
• Temperature Override

PATH: SETPOINTS > S3 CAPACITOR BANK CONTROL > OVERRIDE CONTROL
HI OVERVOLT PKP
Range: Off, 60 to 250 V in steps of 1 VDefault: 120 V
This setting specifies the HI Voltage override level at which the Capacitor Bank will be disconnected from the system. The HI Voltage magnitude must be maintained for a period of time higher than the “Volt Overtime Dly” before the Bank is opened.
If OFF has been programmed, the HI voltage override control is disabled. Once the Override Voltage takes the control of the Bank it doesn’t release it until the voltage falls below the dropout value.
HI OVERVOLT DROPOUT
Range: 60 to 250 V in steps of 1 VDefault: 115 V
This setting specifies the release level of the HI voltage Override control. Once the magnitude of the voltage falls below this level during the “Volt Overtime Dly”, the Override element releases control of the bank and control is passed to the main control programmed in the actual season.
For example, supposing:
HI OVERVOLT PKP = 125 V; HI OVERVOLT DPO = 120 V
The Capacitor Bank will be tripped when the line voltage magnitude reaches 125 V. Thus, the Override control doesn’t release the Bank to the main control until the voltage falls below 120 V.

S3 CAPACITOR BANK CONTROL CHAPTER 5: SETPOINTS
LO OVERVOLT PKP
Range: Off, 60 to 250 V in steps of 1 VDefault: 105 V
This setting specifies the LO Voltage override level at which the Capacitor Bank will be connected to the system. The LO Voltage magnitude must be maintained for a period of time higher than the “Volt OV Time Delay” before the Bank is closed.
If OFF has been programmed, the LO voltage override control is disabled. Once the Override Voltage takes the control of the Bank it doesn’t release it until the voltage rises above the dropout value.
LO OVERVOLT DPO
Range: 60 to 250 V in steps of 1 VDefault: 110 V
This setting specifies the release level of the LO voltage Override control. Once the magnitude of the voltage rises above this level during the “Volt Overtime Dly”, the Override element releases control of the bank and control is passed to the main control programmed in the actual season.
The setting specifies the LO OV Volt Dropout Level as a percentage of the previous setting programmed.
For example, supposing:
LO OVERVOLT PKP = 105 V; LO OV VOLT DPO = 110 V
The Capacitor Bank will be closed when the line voltage magnitude falls below 105 V. Thus, the Override control doesn’t release the Bank to the main control until the voltage increases to above 110 V.
VOLT OVERTIME DLY
Range: 0 to 3600 s in steps of 1 sDefault: 30 s
Temperature Override ControlTemperature override control can be based on two different criteria.
1. Hi temperature override control
2. Lo temperature override controlThe DGC–CB controller checks that "close temp override" is always higher than "Trip temp override". See the document Capacitor Bank Configuration Errors for more information. Hi Temperature Override ControlIf the ambient temperature is higher than the "Cls Overtemp Pkp" setting during the elapsed time programmed in the "Temp Time Dly," the main control is blocked and a Capacitor Bank CLOSE command is issued to switch the Capacitor Bank into the system. The main control will be blocked until the ambient temperature again goes below the HI temperature dropout.Moreover, If the ambient temperature decreases and is lower than the "Open Overtemp Pkp" setting by the elapsed time programmed in the "Temp Time Dly," the main control is blocked and a Capacitor Bank TRIP command is issued by the override control to switch the Capacitor Bank OFF. The main control will be blocked until the increased ambient temperature reaches the LO temperature dropout level.
NOTE
NOTE: The ambient temperature is measured by a PT100 sensor located outside the cabinet and connected to the first RTD input in card IO_G.

Neutral overcurrent protectionThis function is applied to protect the capacitor bank from the phase current unbalance situations. If a capacitor bank blown fuse or a defective circuitbreaker contact disconnects one or two phases, a neutral current will flow through the wye neutral connection of the capacitor bank. In case of grounded wye connected banks, this neutral current can be sensed by a dedicated CT connected between the neutral point and ground. The Multilin DGCC uses the ground CT input to sense this current. The settings associated with Star Neutral IOC element are: PATH: SETPOINTS > S3 CAPACITOR BANK CONTROL > NTRL OVERCURRENT
NTRL IOC FUNCTION
Range: Enabled, DisabledDefault: Disabled
This setpoint enables the Neutral IOC function.
NTRL IOC PKP
Range: 0.05 to 2.50 x CTg in steps of 0.01 x CTgDefault: 1.00 x CTg
This setting sets the neutral instantaneous overcurrent pickup level specified per times CT.
NTRL IOC DELAY

When this setpoint is enabled, a reclosing timer is activated if the Capacitor Bank has been tripped by means of the Neutral Current Unbalance element. When the reclosing time is up, a RECLOSE command is issued.
If the neutral fault persists, a neutral lockout trip is activated. The Neutral Lockout Trip signal can only be removed by a RESET command.

REMOTE OPEN
Range: Off, Contact Input, Virtual Input, Virtual OutputDefault: Off
This setting defines the input to trigger the OPEN command to the switch. This input can be selected from a list of inputs including contact inputs, virtual inputs, protection or control operands, as well as input flags received from SCADA, or IEDs.
This setting defines the input to trigger the CLOSE command to the switch. This input can be selected from a list of inputs including contact inputs, virtual inputs, protection or control operands, as well as input flags received from SCADA, or IEDs.
REMOTE RESET
Range: Off, Contact Input, Virtual Input, Virtual OutputDefault: Off
This setting is used to reset the LEDs, alarms and target messages generated during some abnormal condition of the switch. The setting provides for the selection of an input from a list of inputs. This input performs a reset action upon activation.
OPEN and CLOSE commands over serial DNPThe OPEN or CLOSE command can be initiated from a SCADA or IED using radio communication. The controlling device maps an OPEN or a CLOSE command to its binary outputs and transmits them via radio communication to the controller. Upon reception, the Multilin DGCC controller executes the appropriate action. The Multilin DGCC controller executes the received commands if the controller is not in OFF mode and the selected control mode is set to Auto/Remote (the “Auto” and “Remote” LEDs are lit). The remote OPEN and CLOSE commands over radio are blocked if “Manual” control mode is selected (the “Manual” LED is lit).

If Self-Reset type was selected, entering “On” command will lead to a pulse of one protection pass. To prolong the time of the virtual input pulse, one can assign it as a trigger source to an element with a dropout timer set to the desired pulse time. If “Latched” type is selected, the state of the virtual input will be latched, upon entering “On” command.Refer to the logic diagram below for more details.
Figure 19: Virtual Inputs Scheme - logic diagram
FlexLogic™The Multilin DGCC FlexLogic™ system, defines operators, and lists of operands. In essence, all the necessary information for custom built logic. The FlexLogic tool is accessible from Multilin DGCC EnerVista program under SETPOINTS/ FLEXLOGIC menuAll Multilin DGCC digital signal states are represented by FlexLogic™ operands. Each operand is in one of two states: on (asserted, logic 1, or set), or off (de-asserted, logic 0, or reset). There is a FlexLogic™ operand for each contact input, contact output, communications command, control panel command, element trip, and element alarm, as well as many others.A list of FlexLogic™ operands and operators are sequentially processed once every 4.17 ms or 5 ms, depending on the power system frequency (60 Hz or 50 Hz) (TBC). When list processing encounters an operand, the value of that operand is placed in a first in - first out stack. When list processing encounters a calculation operator, the number of values required for the calculation are removed from the stack, and the result of the operation is placed back on the stack. The operators are logic gates (for example, AND, OR, NOT), timers, latches, one-shots, and assignments. Assignment operators assign the value calculated by the preceding operators to a special class of operands called virtual outputs. Like any other operand, a virtual output can be used as an input to any operator –feedback to achieve seal-in is allowed. When list processing encounters an end operator, processing is stopped until the next processing cycle, at which time it restarts at the top of the list.Each contact output has a setpoint to specify the operand that drives the output. Any operand may be selected – selection of a virtual output is the means by which FlexLogic™ directly controls external equipment such as the motor contactors.The operators used in FlexLogic™ conform to the following rules:
• 512 lines for bulding logic are available in the FlexLogic tool. All lines are executed every 1 / 4 power system cycle (4.17 ms. or 5 ms) (TBC).
• A virtual output may only be assigned once within the FlexLogic environment. An unassigned virtual output will have a value of off.
• A maximum of thirty (32) general purpose timers (timers 1 through 32) are available for configuration. Each timer may only be used once within the FlexLogic environment.
• A maximum of thirty (30) one-shots are allowed.

Contact inputsThe relay is equipped with a number of contact inputs, all of which can be used to provide a variety of functions such as for circuit breaker control, external trips, blocking of protection elements, etc. All contact inputs are wet type contacts (refer to the typical wiring diagram) that require an external DC voltage source. The voltage threshold (17V, 33V, 84V, 166V) is selectable, and it applies for all ten contact inputs. The contact inputs are either open or closed with a programmable debounce time to prevent false operation from induced voltage. Because of de-bouncing, momentary contacts must have a minimum dwell time greater than half power frequency cycle. The debounce time is adjustable by the user.

Each of the contact inputs can be named to reflect the function it represents within the application. Up to 18 alpha-numeric characters are available for names. The debounce time is used to discriminate between oscillating inputs. The state will be recognized if the input is maintained for a period consisting of the protection pass plus the debounce setting.
Range: 0.00 to 9.99 s in steps of 0.01Default: 0.04 s
This setting defines the time to be added to the reset time of the Relay 1 Open[Close] output, thus extending its pulse width. This is useful for those applications where the 52 contacts reporting the breaker state are faster than the 52 contacts that are responsible for interrupting the coil current.
BLOCK RLY 1[2] OPEN[CLOSE]
Range: Off, Contact Input 1 to 10, Virtual Input 1 to 32, Remote Input 1 to 32, Logic Elements 1 to 16Default: Off
This setting defines a block to the Open[Close] Output relay. When the selected input is asserted, the Open[Close] Output relay will be blocked.
Auxiliary OutputRelays 3 to X (Order
Code dependent)
Each auxiliary relay can be selected as either Self-reset, or Latched. If the Self-Reset type is selected, the output relay will be energized as long as the element is in operating mode and will reset when the element drops out. If the Latched type is selected, the output relay will stay energized, after the element dropout, and will be de-energized upon the reset command. If an auxiliary output is only required while the activating condition is present, select Self-Reset. Once an activating condition disappears, the auxiliary relay returns to the non-active state and the associated message automatically clears. To ensure all auxiliary function conditions are acknowledged, select Latched.
5–54 MULTILIN DGCC CAPACITOR BANK CONTROLLER – INSTRUCTION MANUAL
Virtual inputsThere are 32 virtual inputs that can be individually programmed to respond to input commands entered via the relay keypad, or by using communication protocols.Virtual input programming begins with enabling the Virtual Input Function, and selecting the Virtual Input Type Self-Reset or Latched under SETPOINTS > S5 INPUTS/OUTPUTS > VIRTUAL INPUTS. Next, the user can assign a command On/Off to the enabled Virtual Input under SETPOINTS > S4 CONTROLS > VIRTUAL INPUTS. Referring to the Virtual Inputs logic diagram below, a Virtual Input type can be selected to be either Self-Reset, or Latched. When Self-Reset is selected and the “On” command is executed, the virtual input is evaluated as a pulse at a rate of one protection pass. To prolong the time of the virtual input pulse, one can assign it as a trigger source to a logic element with a dropout timer set to the desired pulse time. Selecting the Latched type, will latch the virtual input state, when the “On” command is executed. PATH: SETPOINTS > S5 INPUTS/OUTPUTS > VIRTUAL INPUTS
VI x NAME
Range: 18 CharactersDefault: Virtual IN x
This setting defines a programmable name for the Virtual Input.
VI x FUNCTION
Range: Disabled/EnabledDefault: Disabled
The Virtual Input is enabled and ready to be triggered when set to Enabled.
VI x TYPE
Range: Self-Reset, LatchedDefault: Self-reset
When the Self-Reset type is selected, the Virtual Input will be evaluated for one protection pass only, upon “On” initiation and it will reset. When the Latched type is selected, the virtual input will keep the state “On” until reset command “Off” is initiated.
NOTE
NOTE: See also the Virtual Inputs section under S4 CONTROLS, on how to trigger a virtual input signal state.
NOTE
NOTE: The "On" state of the Virtual Input will not be retained in the case of cycling of the relay control power supply.

CHAPTER 6: COMMANDS
MULTILIN DGCC CAPACITOR BANK CONTROLLER – INSTRUCTION MANUAL 6–3
OPEN and CLOSE commands over DNP addressing, using radioThe OPEN or CLOSE command can be initiated from a SCADA or an IED via radio communication. The controlling device maps an OPEN or a CLOSE command to its binary outputs, and transmits them via radio communication to the Multilin DGCC Capacitor Bank Controller controller. Upon reception, the Multilin DGCC Capacitor Bank Controller controller executes the appropriate action. The controller executes the received commands if the Multilin DGCC control is enabled (the “In Service" LED is lit), and the selected control mode is set to Auto and Remote (the "Auto and Remote" LEDs are lit). The remote OPEN and CLOSE commands via radio are blocked if “Manual” control mode is selected (the “Manual” LED is lit).

M3 STATISTICS CHAPTER 7: MAINTENANCE
M3 Statistics
CountersThere are two counters: DAILY CLOSE OPER, and TOTAL CLOSE OPER. The DAILY CLOSE OPER counter provides information on how many CLOSE operations were made during a day period of 24 hours starting from 12:00 am, the beginning of the current day, until 12:00 am, the beginning of the next day. The counter clears to 0 at 12:00 midnight for each following day. Otherwise this counter can be cleared at any time by issuing a CLEAR COUNTER command.The counter TOTAL CLOSE OPER accumulates the CLOSE operations each time the switch CLOSE command is issued. This counter is not cleared on a daily basis. The counter will stop increasing the number of total CLOSE operations beyond the value 65535. This counter can be cleared at any time by issuing a CLEAR COUNTER command. MIN/MAX per DayThe MIN/MAX PER DAY monitors the minimum and maximum line voltage, as well as the minimum and maximum current, temperature, and reactive power, per day, and records these values for the user’s information. These values can be also monitored through the CB Data Logger over a period of time greater than one day. The MIN and MAX information is recorded during a day period of 24 hours starting from 12:00 am, the beginning of the current day, until 12:00 am, the beginning of the next day. These minimum and maximum values are reset at 12:00 midnight for the following day period. At that time, they are reset to the current line voltage and load current.
