4.2 Diagnostics Check Continued
4. Check that there are no shorted or open control wires from the keying devices to the gate operator. If a keying device fails
to open the gate, momentarily jumper across terminals 1 and 2 on the control board. If the gate operator starts, this indicates
that a problem exist with the keying device and not with the gate operator.
5. Check the supply voltage and batteries. A voltage drop on the supply line (usually caused by using too small supply voltage
wires) will cause the operator to malfunction. Batteries should be fully charged for proper operation, replace batteries every two
years on average.
4.3 Troubleshooting
Symptom Possible Solution(s)
• Check that AC power to the operator is turned ON.
• Check that ANY access control device wired to operator (radio receiver, key switch, exit loop or
safety opening device) has a relay contact time of AT LEAST 1 SECOND to bring the circuit board
out of “idle time” and operate gate.
• Check battery
• Check for 24 VAC at terminals 19 and 20. If voltage measures OK, check the terminal strip or
replace the circuit board.
Operator(s) will not
run. Power LED is
OFF.
• Insure that a minimum of one (1) external entrapment protection device is connected in EACH
entrapment area and the inputs are connected and enabled (UL 325 DIP-switches are turned ON).
• Momentarily jumper terminal 1 to terminal 2. If the input LED does not come ON, check the terminal
strip or replace the circuit board. If LED does come ON, proceed to next steps.
• Check the fuses.
• Check Motor(s):
Remove the circuit board. With two 14 AWG insulated jumper wires, momentarily jumper the battery
terminals to the motor terminals (1, 2) of the Primary operator connector. The operator should run.
Swap the two wires at the terminal strip. The operator should run in the opposite direction. Repeat
these steps using the Secondary operator connector.
• If the operator(s) run in both directions in the step above, replace the control board. If the
operator(s) do not run, or run in only one direction, problem can be a bad operator, wire
connections from the control board to the operator(s) or a bad control board.
• Check the reversing sensitivity.
• Check the secondary safety devices.
• Disconnect the gate from the gate operator and check that the gate swings freely without any
binding.
• Continue troubleshooting or replace the circuit board.
Operator(s) will not
run. Power LED is
ON.
Gate opens a short
distance, then stops
and reverses.
• The entrapment protection device has a fault or the wiring to it is shorted.
Operator will not
run, entrapment
protection input(s)
LED is ON.
• The entrapment protection device is not connected or the wiring to it is open.
Operator will not
run, entrapment
protection input(s)
LED is Blinking.
