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
®
2000XL 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 and will
remain open as long as the contact is held.
Non-Contact Sensors (photo beams/loop detectors)
The GTO/PRO
®
2000XL 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
®
2000XL.

Shadow Loop Connection:
Connect the
COM
wire from the Loop Detector to the
COMMON (COM)
terminal and the other normally open wire
from the Loop Detector to the
SHADOW
terminal on the
GTO/PRO
®
2000XL control board.
PLEASE NOTE:

®
2000XL.
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.
This input is ONLY monitored when the gate is at
the fully open position. Activating this will prevent
the gate from closing.
The GTO/PRO
®
2000XL can also accept "Shadow Loop" input from Loop Detector that provides normally open "dry-
contact" connected to "Shadow" input terminal.
