Adjust the trim pot of the obstruction sensor
Gate ignores the limit switchesCheck that the open limit switch and close limit switch are in the corresponding place.
Check that all motor cable connections, junctions and extensions are properly connected and color-coded. Specifically check the blue and black motor leads
Ensure that the motor cable is away from sources of electrical interference
Check that the limit switch is not faulty
Check that wires to the limit switch are not shorted
Note: To minimize effects cause by electrical interference use twisted pairs of cables with the shield grounded

Viking Q-4 Gate Opener Troubleshooting

Problem Solution
Gate does not open or closeCheck all motor connections to be fully engaged
Check that limit switches are connected to the common and the normally close position
Check that the stop command is not active
Check that the UL command (photo beam and/or edge sensor) is not active
Check that the vehicular loop detectors are working properly
Check that the radio command is not active
Ensure that you external accessories are working properly
Automatic close does not functionCheck that the trim pot of the hold open timer is set to the proper time delay
Note: Hold open timer closes the gate automatically once the gate reaches the limit open
The time delay to close is set by the trim pot
To turn this system off turn the trim pot all the way clockwise
Make sure gate is fully open
Check photobeam path for obstruction
Check photobeam power
Check loop detectors for proper function
Gate opens in the opposite desired directionVerily your motor cable is connected to the proper connector
Check that all motor cable connections, junctions and extensions are properly connected and color-coded
On a Master/Slave installation, one gate runs in the opposite directionCheck the motor and limit switch wiring
Verify that one unit is connected as open-left and one unit is connected as open- right
Verify the interconnecting wiring color codes match on both the master and slave boards
Verify you are using shielded cables and that the shield is connected to the chassis ground at both ends, the master side and at the slave side
Gate opens. Closes or stops on its ownMake sure that the ‘Charger’ LED is on and not flashing, indicating that there is AC power
Check that your wires from your accessories are: a) Not shorting together b) Not shorting a power line c) Not shorting to metal or earth ground
‘Charger’ LED off. Gate does not run - alarm sounds upon any input commandCheck the 4 Amp fuse on the control board
Check the 3 Amp fuse on the EMI control board
Make sure the incoming AC line is properly connected
Check the incoming high voltage power supply
Check the proper selection of power supply (120/220 VAC).
Verify the EMI board by reading high voltage across the (4) blue and red wires at the terminal block connections.
Battery voltage reads zero or very lowEnsure the batteries are connected as follows: a) Left battery - Black terminal connected to the black wire from the harness (jacketed wire) b) Left battery - Red terminal connected to the red wire from fuse holder c) Right battery - Black terminal connected to the red wire from fuse holder d) Right battery - Red terminal connected to the red wire from the harness (jacketed wire)
