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 lin GO/STOP button by lin 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 chec s 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 wor 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" rac 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 lin ed together to create bigger systems.
How to start
 Connect the CEE32/5p plug to the AC400V +-20% power supply – turn the ey to ON
position. When the main power is OK, the power LED will light green, otherwise the unit is
OFF. Chec phase voltages, frequency and contact the manufacturer if help is needed.
 Connect the plugs for the electric hoists to the output soc ets.
 Chec that the emergency STOP mushroom on the device is not engaged or any other lin ed
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 ey
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 loc s the unit to OFF position and must be rotated cloc wise 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 bac light 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 blin ing: 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

Link of WMC remotes
Up to two WMC remotes can be lin ed together to group the operation of STOP and GO buttons. To
lin two WMC units, 5-pin miniXLR cable with custom wire connection is needed.
Never use 1 1 cable – remotes can be destroyed.
When WMC remotes are lin ed, the GO and STOP buttons are lin ed – so press of any STOP and GO
button will wor for both lin ed devices.
Link of Base WLV units
Up to 30 Base units can be lin ed via lin connector located on the front panel.
To lin two WMC units, 5-pin DMX data cable is needed.
Due to safety requirements, the link function works only in LOCAL / LINK MODE
of the controller.

RESET
RESET button wor s for the SIL3 E-STOP relay reset. RESET needs be pressed every time after the
unit is turned ON, the E-STOP mushroom has been pressed or when the GROUP STOP has been
activated.

(8 /16)
EMERGENCY STOP
E-STOP is a red color mushroom. Once the E-STOP button has been pressed, it loc s the unit into
active position and must be rotated cloc wise and released before disengaging. After engaging the
E-STOP button, the RESET button needs to be pressed to reset the system.
GO
This green pushbutton turns the selected channels of Hoist Control system ON when is active. Once
the GO button has been depressed, the energizing of the hoists is turned OFF.
DIRECTION SWITCHES
They allow changing the direction of movement for each motor/hoist separately or in groups. LED
close to the switch indicates the movement direction.
Charger status LED
Status LED of charger located on the front panel is
 Green: Battery is fully charged
 Green blin ing: Battery is charged to 90% or greater capacity
 Orange blin ing: Not in rapid mode – waiting to be charged
 Red: Battery is in rapid charge mode
 Red blin ing: Battery is ultra-rapid charge mode
 No LED: Battery is not inserted
