Troubleshooting Chart
SYMPTOM
POSSIBLE CAUSES
SOLUTIONS
Operator does not
run and diagnostic
display not on.
a. No power to control board
b. Open fuse
c. If on battery power only, low or dead
batteries
d. Inoperable control board
e. Inoperable power board
a. Check AC and battery power
b. Check fuses on the power board
c. Charge batteries by AC or solar power or replace batteries
d. Replace inoperable control board
e. Replace power board
Control board
powers up, but
motor does not
run.
a. Reset switch is in the RESET position
b. Jumper is 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. Inoperable control board
h. Inoperable motor or motor control module
a. Set reset switch to NORMAL OPERATION
b. 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 inoperable control board
h. Replace motor or motor control module
Gate moves, but
cannot set correct
limits.
a. Gate does not move to a limit position
b. Gate is too difficult to move
d. Limits are set too close
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.
d. Change geometry or allow gate to open further
Gate does not fully
open or fully close
when setting
limits.
a. Gate does not move to a limit position
b. Gate is too difficult to move
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.
Operator does not
respond to a wired
control/command
(example: open,
close, SBC, etc.)
a. Check open and close command input
LEDs
b. Reset switch is in the RESET position
c. If on battery power only, low or dead
batteries
d. Entrapment protection device active
e. Vehicle loop detector or vehicle probe
active
a. Check all open and close inputs for a “stuck on” input
c. Set reset switch to NORMAL OPERATION, see page 33
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. Reset switch is in the off position
c. 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.
c. Set reset switch to NORMAL OPERATION, see page 33
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
d. Inherent entrapment protection was
activated while moving
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 Vdc or higher. Charge batteries by AC or
solar power or replace batteries
d. If there are no obstructions in gate path, manually disconnect the gate,
and ensure it moves easily limit to limit. Repair gate as needed.
