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 BLDC Motor Drive Board
a. Check AC and battery power
b. Check fuses on the BLDC Motor Drive Board
c. Charge batteries by AC or solar power or replace batteries
d. Replace inoperable control board
e. Replace BLDC Motor Drive Board
Control board
powers up, but
motor does not run.
a. Reset button is stuck 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 BLDC Motor Drive
Board
a. Check reset button
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 BLDC Motor Drive Board
Gate moves, but
cannot set correct
limits.
a. Gate does not move to a limit position
b. Gate is too difficult to move
c. 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.
c. Ensure the gate moves at least four feet between the OPEN limit and
the CLOSE limit.
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 button is stuck
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
b. Set reset button to NORMAL OPERATION, see page 29
c. Charges batteries by AC or solar power or replace batteries
d. Check all entrapment protection device inputs for a “stuck on” sensor
e. 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 button is stuck
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.
b. Set reset button to NORMAL OPERATION, see page 29
c. 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.
