Description

Specification

Comments

Parallel drive of up to 8 actuators. A master
actuator with an integrated H-bridge controller
controls up to 7 followers.
Actuators with “IC” cannot be operated with PWM (power supply).

Note:
Do not change the power supply polarity on the brownand blue wires!

12-24VDC + (VCC)
Connect Brown to positive
12 V ± 20% - 5 A at max load
24 V ± 10% - 2.5 A at max load
12 V, current limit 8A24 V, current limit 5 A

BlueThe parallel actuators can run on one OR separate power
supplies
Power supply GND (-) is electrically connected to thehousing

12-24 VDC - (GND)
Connect Blue to negative

Current limit levels can be adjusted
through BusLink (only one actuator at atime for parallel)
If the temperature drops below 0°C, all current limits willautomatically increase to 9 A for 12 V, and 6 A for 24 V

The signal becomes active at:> 67% of VIN = ONThe signal becomes inactive at:< 33% of VIN = OFF
Input current: 10 mA
It does not matter where the in/out signals are applied.
You can either choose to connect 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

can be configured with BusLink software according to anyposition needed.
VioletParallel communication:
Violet cords must be connected together

Standby power consumption:
12 V, 60 mA
24 V, 45 mA
No feedback available during parallel drive

WhiteSignal GND:

For correct wiring of power GND andWhite cords must be connected together

Signal GND see next page•••

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 asload indicator.
There are tolerances on the spindle, nut, gear wheels etc. and these tolerances will have an influence on the current consumption for thespecific actuator.

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 together.
