OPERATING INSTRUCTIONS
POWERED GATES
DANGER !
To avoid personal injury or death, do not operate this
equipment with substandard, defective, or missing parts.
Contact a local Autoquip service representative if a
deficiency is found.
WARNING !
Never run the unit with the gates or doors open! The gates
must not open when the lift is in operation or when the platform
is not present. Should this condition exist, the interlock is not
functioning properly due to incorrect installation or damage.
This condition must be corrected immediately. Failure to
correct this condition may result in serious injury or death.
Powered vertical gates are electromechanically driven in both directions using
UP/DOWN operator controls.
UP
When the UP button is pressed or drop cord pulled, the brake motor is started and the
gearbox output shaft rotates the chain sprockets. The gate chains go over these
sprockets and then attach to counter weights. As the motor rotates, the output shaft
turns and raises the gate, provided the motor rotation is correct. If the gate does not
move, check the motor rotation and correct if necessary.
The gate will continue to move upward as long as the button or cord is held. When the
gate panel reaches the upper travel limit switch, the motor will stop and the motor brake
will be applied.
