The GMC-LV Motor Controller was designed to control up to 12 electrically compatible motors, either separately or simultaneously – controlled via CMCseries DIGITAL Cable Remote or WMCseries DIGITAL Controller.

The device is equipped with unique APA (Automatic Phase Align) module, which guarantees that the motors are moving in the same direction on any align of input phases. If any line wire is disconnected, the hoist controller stops to ensure safe operation.

Another feature of GMC-LV is the AVM (Automatic Voltage Metering) module. This module checks main voltage for AC 400V +-20%, star configuration and protects the hoists in case of problem with main voltage.

The unit will NOT go into the safe function if:

  • one phase is missing
  • there is under-voltage on lines
  • there is over-voltage on lines

All electrical components carry their own individual CE and comply with the European Directives. The unit is housed in a robust steel 19" rack with powder coating and complies with CE according to the Certification of conformity that comes with it.

The GMC-LV has an additional key switch for the Group-stop function. When active, the MCB trip of any hoist will cause an E-STOP on all connected hoists.
