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
d. Inoperable control board
e. Inoperable BLDC Motor Drive Board
Control board a. Reset button is stuck in the RESET
powers up, but
motor does not run.
b. Jumper is not in place for stop circuit
c. If on battery power only, low or dead
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
Gate moves, but a. Gate does not move to a limit position
cannot set correct
b. Gate is too difficult to move
limits.
c. 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.
Operator does not a. Check open and close command input
respond to a wired
control/command
b. Reset button is stuck
(example: open,

SOLUTIONS
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
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
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.
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. 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
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.
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.
