SAFETY DEVICE CONNECTIONS
INHERENT OBSTRUCTION SENSING DEVICE:
NOTE: The gate MUST move smoothly and easily in manual
operation before attempting this adjustment.
WARNING:
TURN OFF POWER TO OPERATOR WHEN
MAKING ANY ADJUSTMENTS.
This unit is supplied with a speed sensing system, which will
stop the gate when it encounters an obstruction and then
backs the gate off 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.
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.
