Troubleshooting for Parallel Symptom Possible cause Action No actuators in movement Power supply • Check power supply source and power connections: Brown + Blue Please be aware that if the power supply is not properly connected, you might damage the actuator Signal connections • Check parallel communications: Violet = Communication Violet cords must be connected together White = Signal GND White cords must be connected together Signal required for moving outwards: + VCC (Red wire) • Check wire connection (Red/ Black) on control unit Signal required for moving inwards: + VCC (Black wire) • Put power on all actuators at the same time, after everything is connected. Then wait 10 seconds before signals for moving In/Out are activated Actuator(s) cannot lift full load Load is higher than specified • Reduce load • Check for sufficient power supply current • Connect actuator via BusLink one at the time and check monitoring for each actuator (reason for last stop) Short movements before stops Actuator NOT connected properly • Check wire connection (Violet/ White) Violet = Parallel communication White = Signal GND • If OK - Connect actuators via BusLink one at the time and check monitoring for each actuator (reason for last stop).
