TROUBLESHOOTING
SOLUTIONS
a. Check AC power
b. Check fuses
c. Replace defective control board
a. Check reset switch
b. Check Stop button is not "stuck on", or verify that the stop button is a
normally closed circuit, or put a jumper on the stop circuit.
c. Check all Open and Close inputs for a "stuck on" input
d. Check all Entrapment Protection Device inputs for a "stuck on" sensor
e. Check all vehicle detector inputs for a "stuck on" detector
f. Replace defective control board
a. Use manual disconnect, manually move gate, and ensure gate moves
easily limit to limit. Repair gate as needed.
b. Gate must move easily and freely through its entire range, limit to limit.
Repair gate as needed.
c. Ensure the gate moves at least four feet between the OPEN limit and the
CLOSE limit.
a. Use manual disconnect, manually move gate, and ensure gate moves
easily limit to limit. Repair gate as needed.
b. Gate must move easily and freely through its entire range, limit to limit.
Repair gate as needed.
a. Check all Open and Close inputs for a "stuck on" input
b. Check Stop button is not "stuck on"
c. Check Reset button
d. Check all Entrapment Protection Device inputs for a "stuck on" sensor
e. Check all vehicle detector inputs for a "stuck on" detector
a. Activate wireless control and check XMITTER LED is on. Re-learn
wireless control/transmitter to control board. Replace wireless control as
needed.
b. Check Stop button is not "stuck on"
c. Check Reset button
d. Check if similar wired control operates correctly. Check if wireless
controls works properly when within a few feet of operator. Check
operator's antenna and antenna wire. Check other wireless controls or
devices.
a. Check all Open and Close inputs for an active input
b. Check all vehicle detector inputs for an active detector
a. Check all Open inputs for an active input
b. Check all vehicle detector inputs for an active detector
c. Check Fire Dept input
d. Check Timer-to-Close (TTC) setting
e. Check all Entrapment Protection Device inputs for an active sensor
a. Check all vehicle detector inputs for an active detector
a. Review Exit loop detector settings. Adjust settings as needed.
b. Replace defective Exit loop detector.
a. Review Interrupt loop detector settings. Adjust settings as needed.
b. Replace defective Interrupt loop detector.
