SECTION 1INTRODUCTION TO THE QUANTUM™ HD UNITY

SYSTEM CONTROLLER

SECTION 1 - Quantum HD Unity System Controller

090.670-O (AUG 2015)Page 4


Setup Description

The following Setup Guide is meant to assist the installation technician in making all necessary electrical power, con-trol and communications connections to a Quantum™ HD Unity system. This guide also provides the basic information necessary to login and configure the system, and will aid in troubleshooting the system should problems arise.

This Guide will help to ensure:

Wiring

• Location of incoming AC source power to all panels, main controller and Remote I/O Panels

• Basic installation guidelines are followed.• Location, polarity & grounding of communications wiring.• Location of all control (I/O) wiring.• Proper powering up of all panels.

Configuration

• Logging into the system• Verifying communications.• Configuring Zones• Calibrating sensors.• Setting up operating Setpoints.

Operation

• Setting the operating Mode.• Verifying the data being returned to the Interface panel

from all remote panels. (Zones)• Checking and clearing of alarms.• Ammonia Configuration

Typical System

A system will typically include one Quantum HD Unity System Controller to control the engine room, condensers, vessels and evaporators along with remote I/O panels for the evapo-rators. The I/O for the engine room, condensers and vessels is contained in the Quantum HD Unity System Controller enclosure.

Quantum HD Unity System Controller

Evaporator Remote I/O Panel

One remote Evaporator I/O panel can control up to 3 zones or valve stations. Each system may have one or more Engine Room, Vessel, Evaporator or Condenser remote I/O panels. The Evaporator Remote I/O panel (below) does not have a display.

Typical System Configuration

The typical Quantum HD Unity System Controller consists of one centrally located control and I/O panel that contains the controllers for condenser, vessel, engine room and evapora-tor control. This panel also contains the digital and analog I/O for condenser, vessel and engine room control.

The evaporator I/O is located in smaller remote I/O panels that can be mounted wherever it is convenient for installation and maintenance. Up to 10 remote evaporator I/O panels (30 zones) are controlled by one evaporator controller.

090.670-O (AUG 2015)Page 5


System Installation

Follow these basic installation rules:

• Maximum total serial communications cable distance between the main unit controller and the very last Re-mote Evaporator I/O Panel on any one communications cable run is 2000 feet. It is possible to have two separate communications cable runs depending upon the total number of Remote I/O Panels. Keep in mind, however, that neither of these cable runs can exceed 2000 feet in length.

• Keep all communications wiring in a separate conduit from control or power wiring.

• When wiring for serial communications, it is important to ground only one end of the communications cable. This ground will be located in the very last Remote Panel of each communications cable run. Ground loops could develop if the communications were to be grounded at both ends, impairing communications between panels.

• The Main Unity controller panel is rated NEMA Type-12. This needs to be considered when selecting a location to install the main Quantum HD Unity System Controller enclosure.

• Remote I/O Panels are rated for both indoor and outdoor use. Although the need to access Remote Panels will be rare after installation and setup, it is still advantageous to keep them accessible for potential maintenance situa-tions (reasonable lighting, sufficient door swing, etc.).

• Install all panels within a convenient distance of a power source.

Wiring For AC Power


The incoming AC power will consist of 3 #10 AWG wires (Hot Neutral and Ground that are fed from a 20 Amp service minimum.

• Connect the three incoming AC wires to the terminal screws as shown on the drawings for the Main Quantum HD Unity System Controller enclosure.

• Proceed to the section entitled Checking the AC Power.

Remote Evaporator I/O Panels

The incoming AC power will consist of three 12 AWG wires (hot neutral and ground) from a 15 amp service (minimum).

• Unlatch the two ¼ turn cover latches to the Interface panel, and open the door.

• Inside the enclosure, there is a long DIN rail at the right side of the panel. At the top of the DIN rail is a terminal strip.

• Connect the three incoming AC wires to the terminal screws per the remote evaporator I/O panel drawing.

• Notice that there are multiple number 2 terminals, con-nection may be made to any of them.

Checking The AC Power


• Ensure the Control Power switch is in the OFF position.

• Energize the 120 Volt circuit at its source.

• Using a DVM, measure the voltage at the AC power ter-minal strip. Ensure that you read approximately 120 VAC between Hot and Neutral, and Hot and Ground. There must not be voltage between Neutral and Ground.

• Once the incoming voltage has been verified, turn the Control Power switch to ON.

• Watch the Quantum™ HD Unity controller circuitry on the backside of the door. You should notice various LEDs blinking or flashing.

• Watch the display on the front of the door. After a short period of time, you should notice the display showing a boot sequence. Various text messages will be shown as it proceeds with the boot-up process. When finished, a screen similar to the following image should be visible:

• If the panel has reached the point of showing the previ-ous screen, the boot process was successful. Turn OFF the Control Power switch, and de-energize the 120 Volt circuit at its source.

• If the panel does not reach to the point of showing the above screen, then troubleshooting will be required. Refer to end of this guide entitled Troubleshooting.


• The remote evaporator I/O panel can come with optional HOA switches that can be used to manually energize evaporator zone components. These are easily added in the field after startup if determined to be necessary.

090.670-O (AUG 2015)Page 6


Red, power OFF tab

Black, power ON plunger

• Notice in the above pictorial, there is a Red power OFF tab, and a black power ON plunger. These items are located on a circuit breaker for each of the two HOA modules.

• Push each of the Red power OFF tabs down. The Black power ON plunger should pop up. If the plunger does not pop up, then the power was already off. Do this to both HOA modules.

• Energize the 120 Volt circuit by switching on the control power switch on the right side of the enclosure.

• Using a DVM, measure the voltage at the AC power ter-minals (1, 2 and PE). Ensure that you read approximately 120 VAC between Hot and Neutral, and Hot and Ground. There must not be voltage between Neutral and Ground.

• Above the optional HOA modules are the I/O boards. There will be at least one Digital board (recognizable by the plug-in I/O modules), and one Analog board. Inspect all boards for the presence of flashing, blinking or steadi-ly lit LED’s. If LED’s are lit on all boards, then power has been properly applied.

• If LED’s are not lit on all boards, then refer to the section entitled Troubleshooting.

Wiring For Communications


All serial communications between the condenser, vessel and engine room control are factory wired and tested. Verify that the Rx/TX lights for all analog and digital boards for condens-er, vessel and engine room control are flashing.


Use the following wiring procedure:

• Open the Quantum HD Unity controller door.

• At the bottom left there is a DIN rail with several termi-nals for the Condenser, Vessel, Engine Room and Evapo-rator serial communications. The Condenser, Vessel and engine Room comms are already are factory wired.

• The terminals are marked by product. The Evaporator terminals are marked as

• E -R/T 3 and E +R/T 3 for the first 5 remote I/O panels, and E -R/T 4 and E +R/T 4 for the second set of 5 remote I/O panels.

• Follow the wiring diagrams for both the Evaporator I/O panels and the Quantum HD Unity System Controller/Evaporator Control to properly wire the serial commu-nications observing the grounding points, wire sizes and general serial communications daisy chaining practices

• Refer to the CONDENSER/VESSEL SYSTEM COMMUNICA-TIONS WIRING DIAGRAM to verify dipswitch settings.

CONFIGURATION:

The Configuration page/menu is used to access main areas of configuration such as Pumps and Fans, Summer/Winter Sequence, Condenser Control Setpoints and overrides and Analog Auxiliaries, Communications, P/I Control, Digital and Analog I/O.


Configuration for Pumps and Fans, Summer/Winter Sequence, Condenser VSD, Condenser Control Setpoints and Overrides, Digital I/O and Analog I/O are covered on the following pages. Common configuration items such Digital Auxiliaries, Analog Auxiliaries, Communications and Proportional Integral Control are covered in their respective sections.

Condenser Information – Select the number of individual condenser/s and enter model number and serial number information for each.

Pumps and Fans – Pumps and Fans A-H (8) and I-P (8) are configured on this page. Select each condenser step as a Water Pump, Single Spd Fan, Var Speed Fan or 2-Spd Fan Lo. Selecting a step as 2-Spd Fan Lo automatically sets the next step as 2-Spd Fan Hi. Each step can have an Aux. Failure enabled. Water pumps will have an Outside Air Stop enabled. If selected as a VFD the analog output used for that step is selectable. If set as a 2-Spd Fan Lo/Hi a delay between high speed and low speed is available.

The name for each step is has a default tag relative to the selection and can be changed by the user to match plant designations.

Summer/Winter Sequence – Set the step sequence for the summer sequence on this page. There is also a winter sequence page. The Step On / Off Sequence can be selected as standard or custom. Standard sequence sets the Off sequence relative to the On sequence in a first On, last Off order. Custom sequence allows the user to set both the On and Off sequence to best fit the application.

Condenser VSD Control – If any of the condenser steps are configured as VSD Fan, the VSD control setpoints are on this page. These setpoints are the same as used in other areas for P/I control. The fan control strategy can be selected as one of the following;

• Ramp After All Steps On – After all VSD Fan steps are on at minimum speed (30%), the fans will ramp up and down together.

• Ramp After Each Step – Each VSD Fan is allowed to ramp after it is turned on. When other VSD Fan steps come on they will sink to the speed of the others on line.

090.670-O (AUG 2015)Page 27


Condenser Controller Setpoints

Summer / Winter – Controls setpoints for both Summer and Winter nodes are set on this page. The control setpoint is a calculated value when the Control Strategy is selected as Dynamic. Also selecte between Automatic and manual with regard to transitioning from Summer to Winter modes.

Control / Safety – The following condenser control features are configured on this page.

• Control Strategy – Fixed Setpoint or Dynamic: Dynamic control calculates the wet-bulb temperature along with the condenser approach setpoint and the refrigerant selection to establish a saturated condensing temperature/pressure to control to.

• Condenser Bleed Control – Will control the energizing of a bleed solenoid for a user defined period of time at a user defined interval.

• Alternate Pressure Control – Can be set as Defrost, Standby or Disabled: Often set as defrost, the controller will commu-nicate to the evaporator controller to determine if units are going into defrost. When units go into defrost the Condenser Control Setpoint will change to the Defrost Setpoint on the Summer / Winter setpoints page if the current setpoint is less than that value.

Condenser Control Overrides – Override setpoints are de-signed to take control over the configured control strategies if the operation is outside of the bounds listed below for the associated delay.

Digital I/O – Used to configure standard Condenser Control digital I/O by board and channel as well as display current status. Non-standard items can be configured for monitoring, alarms and control in Digital Auxiliaries configuration. There 4 pages to cover all of the standard I/O for condenser control.

Analog I/O Configuration – Used to configure standard Con-denser Control analog inputs by board and channel. Non-standard items can be configured for monitoring, alarms and control in Analog Auxiliaries configuration.

Analog I/O Configuration (outputs) – Used to configure stan-dard Condenser Control analog outputs for VSD fan control by board and channel. The Analog Outputs page is used to configure the VSD Fan outputs by board and channel if used.

CONFIGURATION: The Configuration page/menu is used to access main areas of configuration such as Zone En-able, Refrigerant Detection, Zone Functions, Zone Cooling, Defrost, Dehumidification, Heating and Re-heating control, Digital and Analog Auxiliaries, Communications, P/I Control, Digital and Analog I/O.


Configuration to enable evaporator zones, refrigerant detec-tion, zone function, zone cooling & defrost, zone heating, load shedding, digital and analog I/O are covered on the fol-lowing pages. Common configuration items such Digital Aux-iliaries, Analog Auxiliaries, Communications and Proportional Integral Control are covered in their respective sections.

Global Zone Configuration – Enable and name up to 30 zones along with defrost grouping, control input selection (entering temp, room temp or user defined temp). User defined naming of the of the user defined temp is done on this page.

Defrost Groups – Up to 10 defrost groups can be configured to better manage the number of units in any one area that are in defrost at the same time.

Global Refrigerant Detection – Name up to 30 refriger-ant detection points with alarm and shutdown values with delays. Up to three refrigerant detection sensor/inputs can be enabled per zone or multiple zones can use the same sensor/input. This is selectable in Zone Function Configuration.

Zone Function Configuration – Enable all zone functions on this page to include cooling, soft hot gas, dehumidification, defrost, heating and reheat. Enable up to 4 modes (capac-ity control setpoints). Configure all valve functions/actions and select refrigerant sensors associated with this zone. If enabled the Dehumidification and reheat setpoints are on the Zone Cooling Modes page and Heating setpoints are on the Zone Heating Modes page.

090.670-O (AUG 2015)Page 47


Dehumidification – Requires an RH% humidity input. If the humidity level is above the on setpoint, cooling (liquid and fan) are turned on even if below their respective off setpoints to remove the non-wanted moisture from the space. A low temp. override setpoint will turn the liquid and fan off to prevent the space from getting too cold.

Reheat – This feature is used in conjunction with de-humid-ification where there is a dedicated reheat coil within the complete coil bundle. This is used to add heat to the space to prevent the space temperature from dropping to low while the cooling coil removes the non-wanted moisture from the space.

Heating – This feature is used to heat a space using hot gas in the main coil. The process of shifting from cooling to heat-ing and back to cooling is essentially the same as when going into and coming out of defrost.

Zone Cooling Modes – Configure each enable mode for each zone for Liquid.

Liquid - Liquid can be by solenoid control or modulating valve control if enable in zone function configuration. I configured for modulation valve additional setpoints for the P/I control of that valve are listed in the liquid section. If not enable only the liquid On and Off setpoints are present.

Fan – The fan can be configured a fixed speed or VSD fan. If fixed only a fan On and fan Off setpoint will be listed in the fan section. If fan cycling is enable in zone function setpoints to cycle the fan On for a period of time and a user defined interval will also appear. If selected as VSD fan as shown hereadditional setpoints for the P/I control will appear.

Alarm – Low and high temperature warning values with de-lays and mode switch delay.

Dehumidification/Reheat – These two features work together to remove unwanted moisture from the space while not allowing the space to get too cold. Requires a special coil within a coil or a secondary coil for the reheat process.

Zone Defrost – Standard defrost timer settings for pump out, soft hot gas, hotgas, bleed, fan delay are provided. If fan is VSD a pump out fan sped setpoint is provided. Initiate defrost from schedule, liquid timer, schedule w/liquid override. De-frost can also be iniated on demand by enabling the feature and energizing the demand defrost digital input.

Power Outage During Defrost – If a power outage occurs during defrost the controller will move straight to the bleed stage on power up to avoid any vapor propelled liquid slug-ging from occurring.

Hot Gas Warning – monitors the evaporator pressure when the hot gas is on to be ensure adequate pressure for defrost. There is also a warning for high pressure. Either a low or high Hot Gas Warning could indicate a problem with the back pressure regulator during defrost. Requires a pressure trans-ducer to read the evaporator pressure.

Manual Defrost Control – is initiated on the zone’s home screen. Once initiated, a service level operator can advance the stages in a manual defrost from the Zone Defrost page.

Defrost Schedule – Up to 8 defrosts can be scheduled per zone per day. The schedule of one day can be easily copied to other days by selecting the day to be copied from and the days to be copied to and touch the copy button.

Zone Heating Modes – Setpoints on this are used to transi-tion to heating mode, control in heating mode and transition back to cooling mode. Heating is an operation of using hot gas to heat a space as needed. Other than the initiation pro-cess, the transition to heating and back to cooling are similar to that of defrost. Fan setpoints are similar to that of cooling.

090.670-O (AUG 2015)Page 48


Load Shedding – Provides a means of reducing system load during certain periods where it is advantageous to do so. This could be during higher rate periods or anytime when the fly-wheel effect will sustain the requirements for the space and product. Units can either be turned off by setting the mode to 0 (zero) or to a higher temperature setting by selecting the mode associated with that setting. An override temp will pre-vent the space from getting too warm. If the unit has a VSD fan, it’s speed during load shed is set on this page.

In and Out of Load Shed Sequence – Is set by the % Differ-ential value that proportionally compares the actual tempera-ture to the difference between the liquid On setpoint and the Override temperature for each zone. Colder units with the lower % differential values go into load shedding first while warmer units with higher % Differential values come out of load shedding first. Any unit that exceeds the Override Temp. comes out of load shedding at that point.

Load Shedding can be initiated manually, by schedule, kW reading or a combination of schedule and kW reading as shown here. Three timed schedules can be set per day. If the kW reading is above the start kW value and within the set start and stop period, load shedding will commence and stay in load shedding until the scheduled stop or the kW value drops below the stop value.

The “Source of kW Reading” is the controller from which a plant wide value can be read, Engine Room Controller or Evaporator Controller. kW control will require a kW meter to be wired into the analog board of the engine room or one of the evaporator zones. The input from this meter should represent the entire plant load or at least the entire refrigera-tion system load.

Zone Digital I/O Configuration – Used to configure standard Condenser Control digital I/O by board and channel as well as display current status. Non-standard items can be config-ured for monitoring, alarms and control in Digital Auxiliaries configuration. There 2 pages to cover each zone of evapora-tor control.

Global Digital I/O Configuration – Global Digital I/O are for the configuration of global evaporator system control outputs. Two commonly used outputs are Main Hot Gas and Main Liquid which can be turned off in the event of a Refrigerant Detection shutdown.

Zone Analog I/O Configuration (inputs and Outputs) – Used to configure standard Evaporator Control analog inputs by sensor range (low/high), sensor type, board and channel. Non-standard items can be configured for monitoring, alarms and control in Analog Auxiliaries configuration. Also configure analog outputs for each zone for VSD Fan and Modulating Liquid Valve.

090.670-O (AUG 2015)Page 49


Global Analog I/O Configuration – Used to configure non-zone specific analog input channels that can be used anywhere in the evaporator system. As an example one NH3 sensor can be linked to all zones for refrigerant detection warning and shutdown. This is where a kW meter input would be config-ured to read to kW load.

Digital Auxiliaries

Digital Auxiliary Inputs – Digital Auxiliary inputs can be con-figured to expand the operation and control of the Quantum HD Unity System Controller beyond that which is standard. They allow the operator to configure additional safeties based on the status of other system components. These can be configured as warning when running, warning always, shutdown when running or shutdown always. The text can be user defined.

Digital Auxiliary Outputs – Digital Auxiliary outputs can be configured to expand the operation and control of the system by configuring digital outputs to energize and de-energize based on an analog value (control Input) relative to the On When and Off When values.

Analog Auxiliaries

Analog Auxiliary Inputs – Can be configured to expand the control and operation of the Evaporator control.

Channel Configuration – Set the Name, I/O Board, Channel and Sensor Output

Sensor Configuration – Displays current value, select Sen-sor Type and set the low range and high range limits of the sensor

Safety Configuration – Configure the safety for when active along with low and high end safeties and their delays.
