Description

Specification

Comments

Parallel drive of up to 8 actuators.
A Master actuator with an integrated H-bridge
controller controls up to 7 Slave actuators.
The version with “IC option” cannot be operated
with PWM (power supply).

VioletViolet cords must be connected together
Signal GND:WhiteWhite cords must be connected together

Note: Do not change the power supply
polarity on the Brown and Blue wires!
The parallel actuators can run on one
OR separate power supplies. Powersupply GND (-) is electrically connectedto the housing. Current limit levels canbe adjusted through BusLink (only one
actuator at a time for parallel). If thetemperature drops below 0 °C, all current
limits will automatically increase to 20 A for
12 V and 15 A for 24 V
The signal becomes active at:> 67% of VIN
The signal becomes inactive at:< 33% of VIN Input current: 10 mA
It does not matter where the in/out signals
are applied. You can either choose toconnect the signal cable to one actuator
OR you can choose to connect the signal
cable to each actuator on the line. Either
way this will ensure parallel drive
Output voltage min. VIN - 2 V
Source current max. 100 mA
Endstop Signals are NOT potential free.
Endstop reached can be configured withBusLink software according to any position
needed.
Standby power consumption:
12 V, 85 mA, 24 V, 50 mA
No feedback available during parallel drive
For correct wiring of Signal GND see nextpage•

Current cut-offs should not be used as stop function! This might damage the actuator.
Current cut-offs should only be used in emergencies!

•Current cut-off limits are not proportional with the load curves of the actuator.
This means that the current cut-offs cannot be used as load indicator.

•There are tolerances on the spindle, nut, gear wheels etc. and these tolerances will have an influenceon the current consumption for the specific actuator.

With Parallel |The parallel system
The parallel drive function will support a number of actuators working jointly:

It is both possible to run parallel with a single power supply, or to run each actuator with separate
power supplies:

Only standard power and signal cables are available for parallel.
If separate power supplies are used, they must have the same potential, and the power supply GND(Blue wires) must be connected in a common ground.
•The signal cables may be 40 meters in total

With Parallel |5BusLink software tool and the parallel system:
The BusLink software tool is available for parallel and can be used for:Configuration, manual run and diagnostics (service counter)
The BusLink software can be downloaded here.
For more information and easy set-up of BusLink, please follow this link to view the Quick Guide.
Please note that the BusLink cables must be purchased separately from the actuator!
Item number for BusLink cable kit: 0367999 (adapter + USB2Lin)
Only through the BusLink software tool is it possible to state if the system is Parallel or 			Non-critical Parallel. Via this tool it is also possible to reconfigure the whole system from one 		system to the other.

The parallel system:• The system does not have to run on one main power supply only – it can be supplied by individual 		
supplies corresponding to the number of actuators in the system. Please respect the actuator 			specifications regarding voltage level and current consumption!
• It does not matter where the IN/OUT signal is applied.
• When all actuators are connected, a Master will automatically be chosen. E.g. with 5 actuators in one 		system there will be 1 Master and 4 Slaves. The Master can control up to 7 Slaves• If an overload occurs, the running of the actuators will be stopped and blocked in that direction until anactivation in the opposite direction has been made, or the system has been re-powered• Before entering BusLink mode, all actuators must be disconnected. It is only possible to configure one 		actuator at a time through BusLink• When changing the actuator configuration, it is important that all actuators in the system have the same
configuration before the system starts running. Otherwise, the actuators will not run• Actuators will be pre-programmed from our production as 2, 3, 4, 5 etc. parallel systems. Through 		
BusLink it will be possible to add or remove actuators to/from the system• In case an actuator drops off the line due to e.g. a damaged signal cable, the parallel system will stop
immediately• In case one of the actuators is broken, the system will not move; not even after re-powering. The
broken actuator needs to be replaced before the system can run again. The system will only run when
it is complete or configured to a Non-critical Parallel system via the Buslink software toolWith Parallel |6

Only for non-critical parallel systems• The Non-critical Parallel system offers auto-detection for every single power up if a new actuator is added
to the line (system)• To add or remove actuators from the system, the system needs to be shut down and powered up again. 		
Please be aware that after re-powering, the system will not detect if an actuator is missing!
• If adding a new actuator to the system, be aware that the actuator needs to have the same configuration(Non-critical Parallel) as the existing ones; this can be done via the BusLink software tool.
System Monitoring for Parallel:
If one of the actuators have one of the following error conditions, the actuator will immediatelySTOP:
••
•
•
•
•
•
•

H-Bridge fault
Out of the temperature range (High duty cycle protection)
Overcurrent (Current cut-off if one or all actuators go in mechanical block)
SMPS fault
Endstop reached signal fault switch
Hall sensor failure
Position lostOvervoltage

Alignment of the parallel actuator system:
If the actuators are not in parallel when starting up, the next movement will run in the following manner:Start position

Running outwards

When completely aligned, theparallel run continues outwards

Start position

Running inwards

When completely aligned, theparallel run continues inwards

IC - Parallel manual service mode:
With the parallel manual service mode it is possible to drive one or more parallel actuators separately, using
the Red and Black wire from each actuator.
Please follow this procedure to manually extend/retract the parallel actuator(s):StepProcedure

Min.

Max.

1. Hold

Put power on the Red and Black wires for
10-30 seconds. Hold with a maximum ofdifference between the two wires.

10 sec.

30 sec.

2. Release

Disconnect all wires and wait 0.5-2 seconds
before the next step. Hold with a maximumof difference between the two wires.

0.5 sec.

2 sec.

3. Extend/Retract

Now choose either to extend or retract theactuator:
To extend the actuator: Connect only the Redwire(s) to the power supply
To retract the actuator: Connect only theBlack wire(s) to the power supply--

4. Interval

Switch between running in/out as much as
needed, without exceeding the 2.0 seconds
interval between disconnecting/connecting
the Red and Black wires-

2 sec.

5. EndTo exit the parallel manual mode, disconnect
the Red and Black wires for more than 2.0
seconds
