Functions and Control

Motor Controller has been designed to control from 1 to 12 electrically compatible motors, either
separately or simultaneously – controlled via switches located on front panel or wireless
remote/pendant. Optionally you can link GO/STOP button by link connector.

Each device is equipped with unique APA /Automatic Phase Align/ module that guarantees that on
any alignment of input phases the motors will move in the correct direction. If any line wire is
disconnected, the hoist controller stops to ensure safe operation. Unit is also equipped with AVM
/Automatic Voltage Metering/ module. This module checks the main voltage for AC400V +-20% and
the star configuration. if there is any problem with the main voltage, you’re notified, and unit will not
run any hoist.

Unit will not work when:

 One phase is missing
 Under-voltage is present on lines
 Over-voltage is present on lines

All electrical components carry their own individual cSA/UL, CE and comply with European Directives.
The components are housed in robust steel 19" rack casing with powder coating. Complete unit
complies with the CE according the Certification of conformity attached to this manual.

Operation

The motors/hoists connected with the GMCseries controller can be activated individually or
simultaneously using the GO switch located on the front panel or wireless remote. Units can be
optionally linked together to create bigger systems.

How to start

 Connect the CEE32/5p plug to the AC400V +-20% power supply – turn the key to ON

position. When the main power is OK, the power LED will light green, otherwise the unit is
OFF. Check phase voltages, frequency and contact the manufacturer if help is needed.

 Connect the plugs for the electric hoists to the output sockets.

 Check that the emergency STOP mushroom on the device is not engaged or any other linked

device in system.

Move lever on the front panel or WMC remote corresponding to each motor to the required
position:

o UP - Lever in upper position
o STAY – Lever in middle position
o DOWN - Lever in lower position

 Pushing the GO button will activate the motors to move simultaneously
 Releasing the GO button will stop the movement of the motors simultaneously.
 When the device is not being used, it is highly recommended to turn it OFF by the key

located on the front panel.

To Move a single/several hoist(s):

 Set the UP/DOWN toggle switch for certain motor to the desired direction. The associated

LED should light green for UP, or red for DOWN direction

 Hold the GO button until the motor is moved the desired height, then release.

WMCseries remote controller

WMCseries remote allows control of the device via wireless connection.

STOP:

This latching pushbutton switch turns the Hoist Control system off. Once the STOP button has been
pressed, it locks the unit to OFF position and must be rotated clockwise and released before
disengaging.

GO:

This pushbutton switch turns the selected channels of Hoist Control system ON, when the unit is
active. Once the GO button has been pressed, the energizing of the hoists is ON. The backlight of GO
button in local mode on the Base unit is ON only when one or more direction switches are in active
position /UP or DOWN/.

DIRECTION SWITCHES:

They allow changing of the direction of movement for each motor/hoist separately:

BATTERY STATUS LED:

Battery status LED indicator:

 Green: 100-90%
 Orange: 90-10%
 Red: 10%
 Red + beep: 5%

REMOTE STATUS LED:

Status LED indicator of WMC remote unit:

 Green: Power ON
 Green blinking: Power ON – SLEEP - move the direction switch or press GO button to resume

from sleep. This status becomes after 3 minutes of inactivity.

 Orange: Indicates direction switch activity
 Red: GO button is pressed – sending commands to the Base unit
