TROUBLE SHOOTING - DOORKING SLIDE GATE OPERATORS, MODEL 9100 & 9150
ACCESS CONTROL SOLUTIONS . . . 12 Preventative Maintenance Guide
Symptom Items to check
Operator will not run 1. Be sure AC power switch is on.
2. Check if Power LED on circuit board is on, (indicates power to
control board.)
Operator will not run 1. Activate Card Reader, Transmitter or Phone Entry. Look at
Power LED is ON circuit board inside Gate Operator and see if LED’s on the
“Keyswitch” or “Full Open” terminals light up when device is
activated. (indicates that the board is receiving open command).
2. Be sure the chain is not too tight. This may cause the operator
to stall. Chain should have approximately 1” of slack per 10’
of gate length.
Gate opens short distance, 1. Check if the how much force is needed to stop the gate. It
then stops and reverses. should take around 40 pounds of force to stop gate. If the
gate can be stopped by less pressure the clutch or reverse
sensitivity may need adjustment. (See Following Page)
2. Check that the chain is not too tight.
3. While gate is moving, check that the counter LED sensors are
blinking (Slide Gate: bottom center of board, above shaft).
4. Turn power off manually roll gate open and closed to check if
there is any binding point, the gate should roll freely
throughout travel.
Gate opens but will 1. Check if circuit board LED’s on terminals 2, 4, 5 or 6 are on.
not close. An input on any of these terminals will hold gate open.
2. Check red LED on Reverse and/or Exit Loop Detectors. If
on then loop is holding gate open. Also check Photo Eye
devices.
Gate starts to close 1. Check for binding of gate at point of reverse.
then reverses to open. 2. Check if the how much force is needed to stop the gate.
3. Check counter LED’s
4. Check Loop Detector LED’s to see if loop is sensing the gate.
Loop Detector LED is 1. Activate reset switch on loop detector (for DoorKing
on continuously. Model 9405, 9406 detectors this is a small push button next to
the large bank of dip switches. To reset press reset button.
TROUBLE SHOOTING HINTS
If a malfunction occurs, isolate the problem to one of three areas: The Operator, The Keying
Devices (card reader, phone entry, etc.) or the Loop Detectors.
When placing a service call to the Authorized Dealer, relate what you found when following the
above steps.
