i)
If Gate functions on ‘Manual’ but does not respond to vend or reset signals;
check control devices and detectors. When possible, exchange known good
components for suspected ones.
ii)
If control devices and detectors are proved OK, the field wiring or harnesses are
to be suspected. Call factory for help.
B.
If Gate runs but cycles up and down without stopping:
i)
Check limit switch adjustment per the above instructions.
ii)
If the limit switches are in their proper location, at least one switch is likely failed.
If the Gate runs on with the 'AUTO-MANUAL' switch in the ‘MANUAL’ position
the UP limit switch has failed. If the Gate runs on in the ‘Auto’ position the
DOWN limit switch is failed.
If gate moves erratically:
Erratic gate motion requires the drive belt tension to be checked. Open the AG812’s door and
inspect the drive belt for looseness or excessive wear. If the belt appears worn or frayed, or if
the belt appears loose, first: remove Electrical Power to the gate and second, tighten or replace
the belt with a new one. To remove or tighten the belt, first loosen the Electrical Motor mounting
nuts slightly and pull the motor away from the Gear Reducer, then tighten the Electrical, motor
mounting nuts, thus tightening the drive belt.
Power Loss
The Delta AG812 can be opened or closed in the event of a power outage by the following:
CAUTION: Power switch should be in the ‘Off’ position when manually operating the
gate to prevent hands from being caught in the drive belt pulleys if motor should happen
to start if power is restored.
1.
Manually pull the drive belt around until the gate is in the desired position. Use Care!
Drive belt-pulley is a pinch point!
2.
Turn Auto-Manual switch to ‘AUTO’ and the Power switch to ‘ON’. On power
resumption, the Gate will automatically resume powered operation.
