1. INTRODUCTION.

1.1. Description

This system is used for detecting any type of uncontrolled movement of the car (UCM) with the doors open. Should an uncontrolled movement occur, the safety series opens, the speed governor is locked and the safety gears are wedged.

It must be used along with a speed governor incorporating a governor rotation locking coil. The coil releases the governor while energised and locks it when de-energised. This coil should be designed to be powered at 24VDC and use a current between 150 and 800mA while energised.

This system compares the status of the car doors and the floor level at all times. Should it detect the car leaving the floor level with open doors, it locks the governor.

When an UCM occurs, a qualified technician is required for the installation to be operative again. Once the problem causing the UCM has been solved, the reset button must be pressed in order to restore the safety series and for the system to be operative again.

The lift controller action is not required to operate the governor coil; the system described operates directly on it.

Should a failure occur either in this contact or in the coil, which may cause a hazard, a system failure signal is activated to report to the controller. When this signal is received, the controller will prevent start-up in the following travel.

In case of using batteries as auxiliary power supply, any charging device shouldn´t be connected between the batteries and the D-Box. The D-Box can charge the batteries by itself.

Important

Connecting a charging device between the D-Box and the batteries can start a fire inside the D-Box. For more details about how to

connect the D-Box to your lift control, see the section 6.3 “Wiring diagrams”.

4.2. Operating environmental conditions

Temperature 5 - 40ºC

Humidity 15 – 85% without condensation

4.3. General Description

The functions of the control buttons and general information supplied by the LEDs and the display are described below.

Control buttons:

RESET2: Enables the system after the first start-up, a UCM, a by-pass action or governor manual tripping.

MANUAL RESCUE/ BY PASS: While activated, D-BOX does not monitor the UCM. It can be used in maintenance operations and perform a manual rescue in case of a power cut-off in the installation. While the by-pass is activated, a periodic sound will be emitted warning that the D-Box is not controlling the UCM. The by-pass function quits by pressing again the “MANUAL RESCUE/BY-PASS” button or by pressing the “RESET” button. This mode's maximum duration with batteries is 5 minutes; after that, the D-Box automatically returns to its normal operation mode. Maximum duration time of this mode with external power is indefinite. If the “MANUAL RESCUE/BY-PASS” button is pressed during normal use, when the “MANUAL RESCUE/BY-PASS” button is pressed again to return to normal operation, the coil will briefly be without power, which may cause the governor to lock.

MAX. 5 minutes

This mode's maximum duration with batteries is 5 minutes; after that, the D-Box automatically returns to its normal operation

mode. To warn about the automatic de-connection, during the last minute, it increases the sound frequency

Applying the by-pass during the process to disengage the safety

gears

After a UCM or a manual tripping, it can be helpful to apply the by-pass, in order to prevent the locking of the overspeed governor in the opposite direction when moving the car to

disengage the safety gears.

2The “RESET” function will not work when the “MOTOR” input is activated.


- 8 -

MANUAL TRIPPING. It is used to lock the governor during maintenance work. It is used

along with the “MODE” button and with an indication on the display to prevent the accidental or unwanted locking of the governor.

MODE3:: Allows enabling manual locking, configuring the de-energising standby time at floor level and configuring the logic of level signals and unlocking zone.

To activate the “MANUAL TRIPPING” mode, please observe the following steps:

o Press “MODE” and “MANUAL TRIPPING” at the same time for three seconds, until the number 55 appears on the display “MODE/SPEED”.

o Press () 20 times until the number 75 is displayed; press “MODE”. The manual tripping LED comes on indicating that this option is enabled. From this moment on, the “MANUAL TRIPPING” button is enabled.

o When “MANUAL TRIPPING” button is pressed, the governor will be tripped.

o When “MANUAL TRIPPING” button is released, the governor will be unlocked.

o To disable the Manual tripping mode and return to normal status, press “MODE” and “MANUAL TRIPPING” buttons at the same time. It can also be disabled by pressing the “RESET” button.

o 15 minutes after the last manual tripping operation, the controller is automatically disabled.

To configure the logic of the floor level signal and the unlocking zone, please observe the instructions in item “7.2. Change in the configuration of level signals and unlocking zone”.

To configure the de-energising standby time at floor level, please observe the instructions in item "7.3 Configure standby time to de-energise the coil with car at level”.

3 If the “MOTOR” input is activated, the mode cannot be configured.

SYSTEM FAILURE: Indicates that the coil has an operation failure. Failure relay reports the controller about it. If this occurs, the controller must prevent a new start-up.

RESET: Indicates that the reset button has been pressed for the system to be in operation again, after the first start-up or an UCM.

MANUAL RESCUE/ BY PASS: Indicates that UCM control is deactivated. If an UCM occurs while in this status, the governor will not be tripped.

MANUAL TRIPPING. Indicates that the governor has been manually tripped by pressing the “MANUAL TRIPPING” button.

DOORS CLOSED: Indicates that the door series is closed.

AUX 1 or BATTERY FAILURE. Indicates that the battery is flat or it isn´t connected.

MOTOR: Indicates that the motor is in operation.

LEVEL: Indicates that the car is at floor level.

UNLOCKING ZONE: Indicates that the car is within the unlocking zone.

AUX 2. Auxiliary LED, without predetermined function.

UNLOCKING SENSOR: Indicates that the unlocking sensor detects that the governor is unlocked.

UCM DETECTED: Indicates that the system has detected an uncontrolled movement (UCM) of the car. In this case, the safety line contact is open.

SPEED GOVERNOR LOCKED: Indicates that the governor coil is not powered, therefore, the governor is locked.


- 10 -

MODE/ SPEED: The figures on the “MODE / SPEED” display indicate the following:

F1: The governor is not released when beginning to move between floors.

F2: UCM detected.

F3: Failure in external power supply.

F4: Failure in coil tripping. It does not interlock when it has to, it interlocks while moving between floors or it is not released when pressing the “MANUAL RECUE/BY-PASS” button.

F5: The coil is not able to unlock the overspeed governor after an UCM or after a manual tripping.

F6: The battery is flat or it isn´t connected. This error only appears when the feeding is switched on.

0.1, 0.2, …2.0: If the governor incorporates an encoder (Vega A3 Plus model with a 500 pulse/rev. encoder), it indicates the car travelling speed.

75: Indicates that the “MANUAL TRIPPING” button is enabled. The moment this button is pressed, the governor will be locked and the safety gears interlocked.

4.4. Description of operation

Depending on the input signals received from the controller, it can detect uncontrolled movements and only locks the governor in these cases. It does not lock it in normal stops.

Basic operation is as follows:

It requires the following input signals from the controller:

Doors closed

Floor level,

Unlocking zone (in cases of installations incorporating door pre-opening or re-levelling)

Motor contactor

When the car reaches a floor, the floor level input is activated, the governor does not interlock and the coil continues energised. The doors open and the closed doors signal is missed. If there is a UCM, floor level input will be missed; at this moment, the safety line contact opens, the coil is de-energised and the governor locks. If there is no UCM, the doors will close and a trip will be made.

Several cases are described in more detail below:


- 11 -

Case 1: Reaching floor and door opening:

Floor level signal is activated, motor input and closed doors input deactivated. Governor coil continues energised and the governor unlocked. To reduce the noise and wear of the governor coil and its associated mechanical components, the governor is not locked at each floor stop. Please refer to “Graph 1 Reaching floor and door opening”

Graph 1 Reaching floor and door opening

Case 2: Car stopped at floor level and doors opened


- 12 -

The car is at floor level with the doors closed. Closed door signal is deactivated. To allow the car to creep within the floor level area during the car loading/unloading, energise the governor's coil. The coil will remain energised during the set time according to item “7.3 Configure standby time to de-energise the coil with car at level.". Please refer to “Graph 2 Car stopped at floor level and door opened”. Note: If the timing is only set for a few seconds, the governor will not unlock when the doors are opened.

Graph 2 Car stopped at floor level and door opened


- 13 -

Case 3: Door closing and operation in normal travel. Closed door signal and motor input are activated, level input is deactivated. Governor coil

continues energised and the governor unlocked. Please refer to “Graph 3 Door closing and operation in normal travel.”

Graph 3 Door closing and operation in normal travel.


- 14 -

Case 4: Out of service for more than programmed standby time. In cases of downtime, with the car stopped longer than the programmed standby time (see item

“7.3 Configure standby time to de-energise the coil with car at level”), the coil will deactivate and the governor will lock. When activity is resumed (motor activation), the coil will activate and the governor will unlock. This function extends the coil’s life and saves energy at night or on prolonged stops.

Case 5: Door opening with car in motion:

Closed door signal is deactivated, motor input activated, level input deactivated. Door opening may cause a cut in the safety line and the subsequent stoppage of the motor. D-Box programmes a period of time long enough (4 seconds) for the car to stop using the machine brakes, later on the governor coil de-energises and the governor interlocks. If the doors close before the programmed time, nothing will happen. Please refer to “Graph 4 Door opening with car in motion”


- 15 -

Graph 4 Door opening with car in motion


- 16 -

Case 6: Governor locked and unable to release

If D-Box receives a locked governor signal (lack of signal in the anti-creep system control sensor) with the coil energised, the safety line opens for 10 seconds. The coil continues energised for 5 seconds. In Display Mode, indication F1 will appear (coil failure). The process is repeated seven times at maximum. If the failure persists for 7 consecutive attempts, the safety line contact will be indefinitely opened and the failure contact will report it to the controller. The “System failure” LED will also light up.

Case 7: Loss of voltage in the installation during a trip.

Closed door and motor signals are deactivated, input signal is deactivated. Voltage loss may cause a cut in the safety line and the subsequent stoppage of the motor. Batteries continue feeding the D-Box. D-Box programmes a period of time long enough (4 seconds) for the car to stop using the machine brakes, later on the governor coil de-energises and the governor interlocks. Please refer to “Graph 5 Loss of voltage in the installation during a trip.”

A minute after the loss of electric power, the LEDs and the display are deactivated to save the batteries’ energy. If any button is pressed, the D-Box is reactivated using energy from the batteries. On regaining the external electric power, the D-Box automatically returns to normal operation mode.


- 17 -

Graph 5 Loss of voltage in the installation during a trip.

Case 8: Performing the emergency operation without voltage in the installation.


- 18 -

Batteries continue feeding the D-Box. The governor is locked. On pressing the “MANUAL RESCUE/BY-PASS” button, the D-Box activates the governor coil, the governor unlocks and allows the rescue. While activated, the by-pass will emit a warning intermittent sound as a reminder that the governor is connected to the by-pass and is not controlling the UCM. On completing the rescue operation, press the “MANUAL RESCUE/BY-PASS” button again to restart the D-BOX’s normal operation. It can also be disabled by pressing the “RESET” button. Please refer to “Graph 6 Emergency operation”

The maximum time for the “Manual rescue/by-pass" status is 5 minutes; after that, the D-Box automatically returns to its normal status.

Graph 6 Emergency operation


- 19 -

Case 9: Car uncontrolled movement (UCM) in installation without door pre-opening or re-levelling.

The car is stopped at floor level with the doors open. Level input is activated. Motor input is deactivated. Door inputs are deactivated. If, under these conditions, the level signal disappears, the control system considers that a UCM has occurred. The safety line opens. The coil is deactivated, the governor is locked and the safety gears are interlocked. Please refer to “Graph 7 Uncontrolled car movement. Installation without door pre-opening or re-levelling”

Graph 7 Uncontrolled car movement. Installation without door pre-opening or re-levelling


- 20 -

Case 10: Car uncontrolled movement (UCM) in installation with door pre-opening.

The car is stopped at floor level with the doors open. Level input is activated. Unlocking zone input is activated.

If the motor is deactivated and the car stopped, the door series will not be shorted; therefore, the closed door input is deactivated. If, under these conditions, the floor signal disappears, even though within the unlocking zone, it implies that a UCM has occurred and the safety line contact will open. The coil is deactivated, the governor is locked and the safety gears are interlocked.

If the motor is activated and the car is within the unlocking zone, the door series will be shorted; therefore, the closed door input is activated. If, under these conditions, the level signal disappears, it does not imply that a UCM has occurred but that it is as found during the door pre-opening process. Should the car leave the unlocking zone with the doors open for any reason, the safety line will no longer be shorted and the closed door signal will disappear. Under these conditions, on leaving the unlocking zone with the doors open, the control system considers that a UCM has occurred. The safety line opens. The coil is deactivated, the governor is locked and the safety gears are interlocked. Please refer to “Graph 8 Uncontrolled car movement. Installation with door pre-opening.”

Important

The response times, and thus the stopping distance, will increase if there is an uncontrolled movement detected by the deactivation of the signal in the unlocking area (case of UCM during the door

pre-opening process).

Case 11: Car Uncontrolled movement (UCM) in a lift installation with re-levelling

If the lift installation has a re-levelling system, contact the Dynatech technical department to find out the behaviour of the UCM system and the connection of the D-Box to the operating control.

Important If the lift installation has a re-levelling system, contact

Dynatech

4.5. Failure description

The possible failures which can be appear during the D-Box working, they possible causes and possible solutions are described in the following table:

4 Check the coil connection at terminals 40-41: Release the connection at terminals 40-41 and check the circuit continuity from the D-Box to the governor coil (for Dynatech parking systems, resistance between terminals must be between 42 and 52Ω).

FAILURE CAUSE POSSIBLE SOLUTION

- 24 -

6.2. Electrical wiring

Before carrying out the electrical wiring, check that there are no risks for the installer's safety.

Before connecting batteries, check that the voltage in their terminals ranges from 11 to 13V.

The incorporation of the UCM control may affect the lift’s maintenance tasks. During the lift's maintenance processes, please bear in mind that the UCM control

is connected. Maintenance personnel must bear in mind that any opening operation off floor level will cause the activation of the safety line and the locking of

the governor.


- 25 -

Power supply:

The system’s power supply (Terminals 30-31) must be connected to a 24VAC/DC source.

Battery power (terminals 32-33). This power supply is used when the main power fails to prevent unwanted jamming. These same terminals are responsible for charging the battery; therefore, it is not necessary to connect any additional charger. If a charger is connected between the D-Box and the batteries, the D-Box may burn.

Obligatory input signals coming from the installation:

Door signal: Terminals 13-14. This signal indicates that the doors are closed. The car doors must be connected in series to the landing doors. The input is equipped with an optocoupler that allows using different voltages, between 24 and 230 VDC/AC.

Drive machine signal (MOTOR): Terminals 15-16. This signal indicates that the motor is running, that is to say, if there is voltage this means that the motor is running; if there is not, this means that the motor is not running at that moment. The input is equipped with an optocoupler that allows using different voltages, between 24 and 230 VDC/AC.

Level signal (LEVEL): Terminals 20-21. This signal indicates that the car is at floor level. The input must be connected to a 24 VDC signal.

In installations with door pre-opening or re-levelling, in addition to level signal, the unlocking zone signal must be connected to their own terminals (22-23).

Important

In installations with door pre-opening or re-levelling, the unlocking zone input must also be connected.

If the lift installation has a re-levelling system, contact Dynatech

Floor level information

See section 7.2 to modify the floor level and unlocking zone settings.

Optional input signals coming from the installation:

Unlocking zone signal (UNLOCKING ZONE). Terminals 22-23. This signal indicates that the car is within the unlocking zone.

In installations without door pre-opening or re-levelling, it is not necessary to connect this input.

Important In installations without door pre-opening or re-levelling, it is not

necessary to connect this input.

Important If the lift installation has a re-levelling system, contact

Dynatech

Unlocking zone

signal See section 7.2 to modify the floor level and unlocking zone

settings.


- 26 -

External manual rescue signal (EXTERNAL MANUAL RESCUE): Terminals 24-25. This signal is used for the controller to execute the instruction from By-pass or manual rescue. If there is voltage, this indicates that the governor must be unlocked and the UCM control function must be cancelled. The input requires a 24 VDC signal. The use of this input is optional. In any case, the by-pass can be performed by using D-Box's MANUAL RESCUE/BY-PASS button. If this input is activated while operating with batteries, the D-Box will stop being on stand-by.

External reset signal (EXTERNAL RESET)5: Terminals 18-19. This signal is used for the controller to execute the reset instruction. If there is voltage, this indicates that the reset function must be executed. The input requires a 24 VDC signal. The use of this input is optional. In any case, a reset can be made by using the D-Box’s reset button. If this input is activated while operating with batteries, the D-Box will stop being on stand-by.

Outputs:

Safety line contact (SAFETY LINE): Terminals 1 and3. This contact is part of a safety relay that opens when an UCM is detected thus causing the safety line to open. As long as there is no UCM, this contact will be closed. In case of a lack of power supply, the contact will open thus causing the safety line to open. In case of coil failure, the contact will also open, but once the motor input is deactivated to allow the car to complete the travel being made at the moment the failure occurred. If the motor is deactivated, it immediately activates on detecting a failure in the coil.

System failure information (SYSTEM FAILURE): Terminals 4-5-6. This output reports the controller that a failure has occurred. On detecting a failure, the normally open (NO) 4-6 contact will close and the normally closed (NC) 5-6 contact will open.

Governor elements connection:

Governor unlocking coil. Terminals 40-41. The coil must be powered with 24 VDC to operate. Coil operation releases the governor locking and allows it to rotate freely. If the coil is not powered, a spring-operated system locks the governor. If there is no electric power in the coil with the car in motion, the governor is locked and the jamming of the safety gears may occur; therefore, the use of batteries is necessary to prevent unwanted jamming in case of a power cut off in the lift.

Inductive sensor: Terminal 42 (inductive sensor 0VDC power supply), Terminal 43 (detection), Terminal 44 (inductive sensor 24 VDC power supply). Inductive sensor signal: The governor incorporates a control sensor to check that the coil is operating properly. This signal indicates that the speed governor is unlocked, that is to say, if there is voltage, this indicates that the governor is unlocked; if there is not, this indicates that the governor is locked.

Encoder: Terminals 45, 46, 47, 48 and 49.

The signal from the encoder is used to indicate the car’s travelling speed on the display. The encoder signal does not intervene in the UCM detection. Encoder connection is optional.

5 The “RESET” function does not work when the “MOTOR” input is activated.


- 27 -

Important Encoder connection is optional. D-Box performs its monitoring function without requiring an encoder.

7. OPERATION REQUIREMENTS

7.1. First start-up

When carrying out the first start-up, the reset button must be pressed to restart the system.

It is not necessary to press the reset button after a power failure.

7.2. Changing the level and unlocking zone signals settings.

Some installations supply the signal of the car at floor level with 24 V and the signal of the car off floor level with 0 V. However, other installations supply the signal of the car at floor level with 0 V and that of the car off level with 24 V. The D-box can be set to adapt to both types of installations, including those incorporating an unlocking zone.

The D-Box is configured by default for installations that supply the signal of the car at floor level with 24 V, and that of the car off floor level with 0 V, and the unlocking zone, if any, with 24 V; that is to say, the original settings must be in accordance with the following table:

Input 21

Input 23

Car at floor level 24 VDC

Car within the unlocking zone, if

any 24 VDC

Car off floor level 0 VDC

Car out of the unlocking zone, if

any 0 VDC

There are some installations where information about floor level or the unlocking zone, if any, is the opposite of the previous one, that is to say, in accordance with the following table:

Input 21

Input 23

Car at floor level 0 VDC

Car within the unlocking zone, if

any 0 VDC

Car off floor level 24 VDC

Car out of the unlocking zone, if

any 24 VDC

Even, the possibility of connecting it to installations where floor level is with 0 V and the unlocking zone with 24 V and vice versa is considered.


- 34 -

The following process must be followed to consult the settings of floor level and unlocking zone:

Press the “MODE” button for 3 seconds.

The coded information about the input settings will appear on the display according to the following table:

Press the “RESET” button to exit without saving changes.

The following process must be followed to modify the original settings:

Press the “MODE” button for 3 seconds.

The coded information about the default settings will appear on the display: 11 (indicates LEVEL = 24 VDC, UNLOCKING ZONE = 24 VDC)

Press the button (). The coded information will appear on the display: 10 (indicates LEVEL = 24 VDC, UNLOCKING ZONE = 0 VDC)



When the target setting appears on the display, press the “MODE” button to save changes, or press the “RESET” button to exit without saving changes.


- 35 -

7.3. Configure standby time to de-energise the coil with car at

level.

The D-Box can modify the standby time to de-energise the coil when the car is at floor level without moving. This value is, by default, 10 minutes but it may be configured in a range from 0 seconds to 10 minutes.

To modify it, please observe the following steps:

Press the “MODE” and “MANUAL TRIPPING” buttons at the same time for three seconds, until number 55 appears on the “MODE/SPEED” display.

Press () 8 times until number 63 is displayed; press “MODE” The display will show the value of this standby time previously programmed. By default, it is 10 minutes (1.0 on the display). Timing can be programmed from 0 seconds to 10 minutes. It is increased second by second, from 0 seconds to 59 seconds, and minute by minute, from 1 minute to 10. The value in minutes is represented via a dot between both digits on the display. For example: 2 minutes is represented as 0.2). In the case of timing in seconds, no dot is displayed (for example: 2 seconds is represented as 02).

Once the target timing has been selected, exit by clicking on the "MODE" button. To exit without saving the selection, click on “RESET”.

7.4. Check-up test process

Before commissioning, the following check-up test process must be carried out, and later periodically:

Note

The following tables are displayed for a floor level at 24 V setting. In installations with a floor level at 0 V setting, the testing process is similar, but the signals of LEVEL and UNLOCKING ZONE, if any, will be OFF instead of ON.
