SYMPTOM
POSSIBLE CAUSES
SOLUTIONS
Operator does not
run and error code
display not on.
a) No power to control board
b) Open fuse
c) If on battery power only, low or dead batteries
d) Defective control board
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
Control board
powers up, but
motor does not
run.
a) Reset button is stuck
b) Stop button active or jumper not in place
for stop circuit
c) If on battery power only, low or dead batteries
d) Open or Close input active
e) Entrapment Protection Device active
f) Vehicle loop detector or probe active
g) Defective control board
a) Check Reset button
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
Arm moves, but
cannot set correct
limits.
a) Arm does not extend or retract enough
during travel
b) Arm is interfering with mounting bracket
c) Gate is too difficult to move
a) Disengage the arm and ensure arm moves freely
b) Examine the hinge point where the arm mounts to the gate post. Make
sure that the arm housing does not hit or interfere with the gate post or
mounting bracket. Correct as necessary.
c) Disconnect arm from gate and move gate manually. Gate must move easily
and freely through its entire range, limit-to-limit. Repair gate as needed.
Gate does not fully
open or fully close
when setting
limits.
a) Arm does not extend or retract enough
during travel
b) Arm is interfering with mounting bracket
c) Gate is too difficult to move
a) Disengage the arm and ensure arm moves freely
b) Examine the hinge point where the arm mounts to the gate post. Make
sure that the arm housing does not hit or interfere with the gate post or
mounting bracket. Correct as necessary.
c) Remove arm from gate and move gate manually. Gate must move easily
and freely through its entire range, limit-to-limit. Repair gate as needed.
Operator does not
respond to a wired
control/command
(example: Open,
Close, SBC, etc.)
a) Check Open and Close command input LEDs
b) Stop button is active
c) Reset button is stuck
d) If on battery power only, low or dead batteries
e) Entrapment Protection Device active
f) Vehicle loop detector or vehicle probe active
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
Operator does not
respond to a
wireless control or
transmitter
a) Check XMITTER LED when wireless
control is active
b) Stop button is active
c) Reset button is stuck
d) Poor radio reception
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.
Gate stops during
travel and reverses
immediately.
a) Control (Open, Close) becoming active
b) Vehicle loop detector active
c) Low battery voltage
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 23.0 Vdc or higher. Charge batteries by AC or
solar power or replace batteries
Gate opens, but
will not close with
transmitter or
Timer-to-Close.
a) Open control active
b) Vehicle loop detector active
c) Loss of AC power with AC FAIL set to
OPEN
d) Low battery with LOW BATT set to OPEN
e Fire Dept input active
f) Timer-to-Close not set
g) Close Entrapment Protection Device active
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 23.0 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
