TROUBLESHOOTING FAULT POSSIBLE CAUSE FIX OPERATOR IS DEAD When power is supplied to the control board, no LED turns ON. 1) Battery fuse is blown. 2) Battery or Run Transformer connection is loose. 3) Dead battery. 4) Bad control board. ➤ Replace battery fuse. Use only 20A, ATC style fuse. ➤ Check battery and transformer connections. OPERATOR DOES NOT RUN Unit does not respond to a Radio command. 1) Low battery. 2) Radio (remote) not programmed. 3) STOP button connection loose. STOP LED is OFF.
TROUBLESHOOTING FAULT GATE RUNS TOO SLOW GATE DOES NOT CLOSE AUTOMATICALLY POSSIBLE CAUSE FIX 1) Open and Close Limits are set too close together. ➤ If the Open and Close Limits are set within the ramp down distance of each other, the gate will run at slow speed all the time. 2) The gate is starting within the ramp down distance from the Open or Close Limit. ➤ Gate will run slow to limits if motion is started within the ramp-down distance from the limit.
