SYMPTOM POSSIBLE CAUSES
Operator does not a. No power to control board
run and diagnostic
b. Open fuse
display not on.
c. If on battery power only, low or dead
batteries
d. Inoperable control board
e. Inoperable power board
Control board a. Reset switch is in the RESET position
powers up, but
b. Jumper is not in place for stop circuit
motor does not

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
Gate moves, but a. Gate does not move to a limit position
cannot set correct
b. Gate is too difficult to move
limits.
d. Limits are set too close
Gate does not fully a. Gate does not move to a limit position
open or fully close
b. Gate is too difficult to move
when setting
limits.

activated while moving
TROUBLESHOOTING
SOLUTIONS
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
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
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
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
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
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.
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.
