4. Gate 1 or Gate 2 (Gate 1

and Gate 2 if dual gate)

operating speed has

slowed down

When the gate is running slow, the reason is low power. The

Sentry charge controller does not output any voltage or current

when disconnected from the battery, you cannot check the

charge controller by disconnecting from battery and measuring

output voltage. To check charge controller output, disconnect

from battery, measure battery voltage and note. Reconnect

charger and monitor battery voltage it should rise above the

battery voltage noted above.
Two things need to be considered.
1. Battery condition (replace or charge)
2. the 1/4” ring terminals located on the Plug N Go harness

which are connected to the battery. The ring terminals can

become corroded and need replacing over time.

Remove battery and have it load tested at a battery shop.

Replace if bad.

5. Single or Dual gate

installation will not

automatically close

If control switch number 1 is turned “ON” then the gate will

only auto close from the fully open position.

1. Locate the “Open/Close Command “push button; press the

button to verify that the gate will close. If gate closes correctly

then proceed to the steps below. If gate will not close go to

step 5.

2. Verify that control switch number 1 is turned “ON”. Gate must

be cycled once switch is turned “ON” for control board to

recognize switch setting.

3. If your installation is a single gate verify which linear actuator

connector (Gate 1 or Gate 2) on control board you are using.

Then verify that the control switch for that Gate is turned

“ON” and the other is turned “OFF”.

4. If photo eye or other safety accessory is connected to J2

then we need to verify correct operation of the accessory. To

determine if this might be the problem disconnect the wire

that is connected to J2 pin 5 and cycle gate to see if problem

persists. If gate auto closes, accessory disconnected is

holding gate open verify wiring and operation of device.

5. The receiver P2 relay could be set for latch open mode. To

verify: press the transmitter button 2 one time, then press the

transmitter button 1 one time and see if gate closes. If gate

closes, then the hold open mode was enabled. For more

information see page 22.
