TROUBLESHOOTING
SOLUTIONS
a) Check AC and battery power
b) Check fuses
c) Charge batteries by AC or solar power or replace batteries
d) 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) Charges batteries by AC or solar power or replace batteries
d) Check all Open and Close inputs for a "stuck on" input
e) Check all Entrapment Protection Device inputs for a "stuck on" sensor
f) Check all vehicle detector inputs for a "stuck on" detector
g) 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.
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) Charges batteries by AC or solar power or replace batteries
e) Check all Entrapment Protection Device inputs for a "stuck on" sensor
f) 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
c) Battery voltage must be 11.5 Vdc or higher. Charge batteries by AC or
solar power or replace batteries
a) Check all Open inputs for an active input
b) Check all vehicle detector inputs for an active detector
c) Check AC power and AC Fail option setting
d) Check if AC power is available. If no AC power, then running on batteries
and battery voltage must be 11.5 Vdc or higher. Charge batteries by AC or
solar power or replace batteries.
e) Check Fire Dept input
f) Check Timer-to-Close (TTC) setting
g) Check all Entrapment Protection Device inputs for an active sensor
a) Check all vehicle detector inputs for an active detector
b) Check if AC power is available. If no AC power, then running on batteries
and battery voltage must be 11.5 Vdc or higher. Charge batteries by AC or
solar power or replace batteries.
