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.
