• Momentarily jumper terminal 6 to terminal 14. If input LED does not come ON, check terminal strip
or replace control board. If LED does come on, go to the next step.
• Momentarily jumper terminal 2 to terminal 3 (Caution – High Voltage). The motor should run.
• Momentarily jumper terminal 2 to terminal 4 (Caution – High Voltage). The motor should run in
opposite direction of above.
• If motor does not run in either or both steps above, bad motor, motor capacitor or wiring to motor.
Operator will not
run. Power LED
is ON.
• Check to be sure, switch 4 is in the ON position.
• Down input must be activated, and then deactivated to cause arm to rotate down.
Down input / down
loop will not rotate
arm to down
position.
Loop detector LED
is on continuously.
Symptom Possible Solution(s)
Loop detector LED
never activates.
Battery back-up
system will not
raise arm upon
power outage.
• Increase loop detector sensitivity.
• Check continuity of loop wire. Should be 0 ohms. If continuity check indicates anything other than
0 ohms, check all connections. Replace loop wire.
• Move loop detector board to the other loop detector port on the control board, and then check loop
operation. If loop detector still fails, replace loop board.
• If loop detector operates OK in the other loop port, replace control board.
• Check that the back-up system toggle switch is in the ON position.
• Check to be sure that the 2340-010 battery back-up control board switch settings are set as
described in SECTION 6.
• Check the batteries for proper voltage, replace if necessary.
• Replace the 2340-010 Back-up control board.
• Activate the reset switch on the loop detector.
• Decrease loop detector sensitivity.
• Check loop wire for resistance to ground with meg-ohm meter. Should be 100 meg-ohms or higher.
If less than 50 meg-ohms, replace loop wire.
• Be sure loop lead-in wire is twisted at least 6 turns per foot.
• Be sure all loop connections are soldered.
• Replace loop detector.
• Check LEDs on terminals 6, 7 and 9. Any of these ON will hold the arm in the UP position. This
indicates a shorted input.
• Check the LEDs on the loop detectors. Any ON will hold the arm in the UP position. Possible loop or
loop detector problem.
• If auto timer is not used (SW 1, switch 7 off ), check to be sure SW 1, switch 6 is in the ON
position. This will cause terminal 6 to rotate the arm down when it is activated.
• Check to be sure SW 1, switch 4 is ON. This will cause terminal 8 activation, then deactivation to
rotate arm down.
Arm rotates up,
but will not
rotate down.
