SAFETY DEVICE CONNECTIONS
INHERENT OBSTRUCTION SENSING DEVICE
NOTE: The gate MUST move smoothly
and easily in manual operation before
attempting this adjustment.
This unit is supplied with a current sensing
system, which will stop the gate when it
encounters an obstruction, and then backs
the gate o approximately 2 inches. If the gate is started again and a second encounter
occurs before hitting a limit switch, the gate will stop and sound a warning signal. A constant
pressure control will then be needed to start the gate.
This sensing system has sensitivity adjustments located on the printed circuit board. The
force required to activate the system may be adjusted in both OPEN and CLOSE directions
separately. Start at minimum and increase force setting until it is just over what is required to
move the gate smoothly without any nuisance tripping.
TURN OFF POWER TO OPERATOR
WHEN MAKING ANY ADJUSTMENTS!
WARNING
NEVER INCREASE FORCE SETTING TO
MAKE UP FOR A GATE THAT IS NOT
MAINTAINED PROPERLY. THIS WILL
DESENSITIZE THE OPERATION OF THE
SAFETY SYSTEM.
