TROUBLESHOOTING
SOLUTIONS
a. Refer to the Adjustment section to conduct the obstruction test and
perform the proper force adjustment that is needed.
a. Check photoelectric sensor wiring. Retest that obstructing photoelectric
sensor causes moving gate to stop, and may reverse direction.
b. Replace defective photoelectric sensor. Retest that obstructing
photoelectric sensor causes moving gate to stop, and may reverse
direction.
c. Move the photoelectric sensors closer together or use edge sensors
instead.
a. Check edge sensor wiring. Retest that activating edge sensor causes
moving gate to stop and reverse direction.
b. Replace defective edge sensor. Retest that activating edge sensor causes
moving gate to stop and reverse direction.
a. Check for cause of entrapment (obstruction) detection and correct. Press
the reset button to shut off alarm and reset the operator.
a. Change setting of both operator's Bipart switch settings. One operator
should have Bipart switch ON (operator that opens second) and the other
operator should have Bipart switch OFF (operator that opens first).
a. Pre-warning is set to "ON"
b. Constant pressure to open or closed is given
a. Check main board to expansion board wiring. If required, replace wire
cable.
b. Check wiring to all inputs on expansion board.
c. Replace defective expansion board or defective main board
a. Check that Maglock is wired to N.C. and COM terminals. Check that
Maglock has power (do not power maglock from control board
accessory power terminals). If shorting lock's NO and COM wires does
not activate Maglock, then replace Maglock or Maglock wiring (refer to
Wiring Diagrams).
a. Check that Solenoid is wired to N.O. and COM terminals. Check that
Solenoid has power (do not power solenoid from control board
accessory power terminals). If shorting lock's NC and COM wires does
not activate Solenoid, then replace Solenoid lock or Solenoid wiring
(refer to Wiring Diagrams).
a. Check that Quick Close setting is ON
b. Check operation of Interrupt Loop detector
c. Replace defective Expansion board
a. Check that Anti-Tail setting is ON
b. Check operation of Interrupt Loop detector
c. Replace defective Expansion board
a. Check AUX Relay switches settings
b. Check that wiring is connected to either N.O. and COM or to N.C. and
COM.
c. Set AUX Relay to another setting and test. Replace defective expansion
board.
