6400 installation guide 25

Have the following diagnostic

tools available: VOM meter with

minimum voltage memory or

min-max range to check voltage

and continuity. Meg-ohm meter

capable of checking up to 500 meg-

ohms of resistance to properly

check ground loop integrity. A

malfunction can be isolated to one

of the following:

• Gate

Operator

• Loop

System

• Keying

Devices.

Disconnect all external inputs to

the circuit board.

1. Check the input indicator LED’s.

They should only come ON when

a keying device (card reader,

push button, etc.) is activated.

If any of the input LED’s are ON

continuously, this will cause

the gate operator to hold open.

Disconnect the keying devices

one at a time until the LED

goes OFF (see troubleshooting

guide).

2. If the operator stops or holds

open, check external secondary

entrapment protection devices

for any shorts or malfunction.

3. A malfunction in a loop or

loop detector can cause the

gate operator to hold open, or

not detect a vehicle when it is

present over the loop. Pull the

loop detector circuit boards from

the loop ports on the operator

circuit board. If the malfunction

persists, the problem is not

with the loop system. For more

information refer to the loop

detector instruction sheet and

the DoorKing Loop and Loop

Detector Information Manual.

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.

Condition

Possible Solution

Actuator(s) will not
run. Power LED
is OFF.

Check that power to the operator is turned ON.

Check for 24 VAC at terminals 19 and 20. If voltage measures OK,

check the terminal strip or replace the circuit board.

Actuator(s) will
not run. Power
LED is 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.

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 actuator connector. The actuator should run. Swap

the two wires at the terminal strip. The actuator should run in the

opposite direction. Repeat these steps using the Secondary actuator

connector.

If the actuator(s) run in both directions in the step above, replace

the control board. If the actuator(s) do not run, or run in only one

direction, problem can be a bad actuator, wire connections from the

control board to the actuator(s) or a bad control board.

Gate opens a
short distance,
then stops and
reverses.

Disconnect the gate from the actuator and check that the gate swings

freely without any binding.

Check the reverse sensitivity.

Check the secondary safety devices.

Replace the circuit board.

Gate opens but
will not close.

Check the input LED’s. Any ON will hold the gate open and indicates

a problem with a keying device.

Check the secondary safety devices. Any activated will hold the gate

open and indicates a problem with the safety device.

Check the loop detectors. Any activated can hold the gate open and

indicates a problem with the loop detector or ground loop.

Operator may be in a “soft shutdown.” Activate any keying device to

determine if operator returns to normal operation.

If automatic close is desired, be sure SW1, switch 4 is ON.

Gate closes but
will not open.

Operator may be in a “soft shutdown.” Check input LED’s. If any are

ON, momentarily disconnect, then re-connect the wire going to the

input terminal. Actuator should open.

Check to be sure that the actuator is running in the proper direction.

Turn power OFF, disconnect batteries and solar panels, and then

back ON. Activate a keying device. Actuator should run in the open

direction. If actuator runs in the close direction, turn power OFF

and change direction switch SW1, switches 1 and/or 2. Re-test and

reconnect batteries and solar panels.

Be sure that the respective LED on the control board lights when the

keying device connected to the respective terminal is activated. If

LED does not light, momentarily place a jumper wire from terminal

1 to the input terminal being checked. If LED lights and gate opens,

problem is with the keying device. If LED does not light, replace

control board.

Gate starts
to close, then
reverses to open.

Disconnect the gate from the actuator and check that the gate

operates freely without any binding.

Check the loop detector LED’s and input LED’s. Any that fl ash ON

will cause the gate to reverse.

If a shadow loop is used, check for proper wiring. A mis-wired

shadow loop detector will cause the gate to reverse.

Replace the circuit board.

Gate closes and
then re-opens.

Check for any input or loop detector LED’s that are ON.

Check that the operator is running in the proper direction (see “gate

closes but will not open” above).

Alarm sounds for
5 minutes and
then beeps once
every 5 seconds.
Operator will not
run.

Operator is in a “hard shutdown” condition. Reset switch must be

activated to return operator to normal operation.
