Refer to the sensor manufacturer’s instructions for information
about installing these devices on a vehicular gate.
Make sure the power switch to the opener is turned
off before connecting safety device wiring to the
terminal blocks. Unplugging the transformer does
not turn power to the opener OFF.
Non-Contact Sensor Connection:
Connect one of the non-contact sensor dry contact output wires to
the
COMMON (COM)
terminal and the other to the
SAFETY
terminal on the GTO/PRO SW-2500 control board.
This input is ONLY monitored when the gate is
closing. Activating the non-contact sensor
(obstructing the safety beam path) will cause the
gate to reverse to the fully open position.
Non-Contact Sensors (photo beams)
The GTO/PRO SW-2500 can also accept "Safety" input from normally open "dry-contact" output devices such as photo
beams connected to the SAFETY input terminal.
If not installing a non-contact sensor skip to next section.
PLEASE NOTE:
Non-contact sensors are not
included with
the GTO/PRO SW-2500.
Shadow Loop
If not installing a shadow loop skip to next section.
Refer to the sensor manufacturer’s instructions for information
about installing these devices on a vehicular gate.
Make sure the power switch to the opener is turned
off before connecting safety device wiring to the
terminal blocks. Unplugging the transformer does
not turn power to the opener OFF.
Shadow Loop Connection:
Connect one of the shadow loop wires to the
COMMON (COM)
terminal and the other to the
SHADOW LOOP
terminal on the
GTO/PRO SW-2500 control board.
PLEASE NOTE:
Non-contact sensors are not
included with
the GTO/PRO SW-2500.
The
SHADOW LOOP
is a detector located within the moving
path of the gate to prevent the gate from closing when a vehicle is
in the path.
