7.10 Interfacing between G.A.L. certified light curtain and MOVFR:
A. Procedure:
To take full advantage of the MOVFR and simplify the REOPENING circuits for the Door Operators,
the REOPEN relay in the MOVFR board should be used to Reopen the doors in cases of:
• Exceeding the limit of the torque allowed.
• Exceeding the limit of the speed allowed.
• Obstructing the light curtain.
The exceeding Torque and exceeding Speed features have already been built in the MOVFR board.
Additionally, for the obstruction of the Infrared Light Curtains, the following illustration shows the
interfacing procedure of a G.A.L. Certified Infra-Red Light Curtain and the G.A.L. MOVFR board.
Followings are the G.A.L. Certified Infrared Light Curtain Detectors, in alphabetical order, that are
available from G.A.L Mfg. Corp (http://www.gal.com).

• Formula Systems
• Tri-Tronics
B. Operation:
When obstruction on the edges occurs, the reopen LED on the MOVFR will turn on and the reopen
relay will be activated. The reopen contacts will send reopen signal to the main controller and wait for
the DO (Door Open) Signal from the Main Controller to Reopen the door.
