FAULT

POSSIBLE CAUSE

FIX

MASTER OR SECOND 1) Failure to cycle power after setup

OPERATOR IS NOT

FUNCTIONING PROPERLY

2)Communication wiring may be damaged or improperly wired for dual gate operation

3)Master or second unit is not programmed correctly

➤The power to each unit must be cycled in order to initiate proper master/second communication if the operators were previously in stand-alone mode.

➤Make sure that the communication wire that is used is twisted pair and not run in the same conduit with any power wiring. Failure to do so will result in interference across the master/second communication line.

➤Review program settings on page 18 and check both the master and second for proper programming.

OPERATOR RUNS BUT THEN STOPS AND REVERSES DIRECTION

1)Entrapment (force pot) incorrectly set ➤ This pot must be set so that the gate will run smoothly normally and reverse when encountering an obstruction.

2)

Gate is binding or not running

➤ Disengage the manual release and roll gate open and close by hand at

normal operating speed. Make sure that the gate runs smoothly and

➤ Observe the drive wheels as they move the gate. If the wheels slip on

➤ Make sure that the brake operates correctly. The brake should

 

 

disengage when the contactor activates and engage when the

➤ Both LEDs will indicate the activation of entrapment protection

 

 

devices on terminals TB1-9 and TB1-10 on the GL board. Remove the

 

 

devices and retest. If the operator now runs without fault, check those

➤ Make sure that the sensor is adjusted so that it is centered over the

 

aligned/adjusted correctly

limit shaft’s magnet and is 10-15 thousandths of and inch (business

 

 

card thickness) from the magnet.

 

 

➤ Replace the sensor if it is adjusted correctly but continues to fail.

MOTOR RUNS BUT GATE

1) Operator’s manual release is engaged.

 

➤ Make sure that the unit’s manual release is not engaged. The unit’s

2) Operator’s main power is out of phase

 

➤ Turn off the unit’s main power at the breaker and swap any two

 

(three phase only).

 

power leads at the operator’s main power switch. Apply power and

 

 

 

retest the operator. See important note on page 13.

 

 

OPERATOR OPENS

IMMEDIATELY UPON POWER UP AND DOES NOT CLOSE

1)Active or malfunctioning accessory check the red input status LEDs, D11-D13

➤If any red LEDs are on, check the corresponding input. An installed accessory may be wired incorrectly or malfunctioning. Remove the accessory and test the operator.

➤If the soft open or interrupt loop LED is on, make sure factory plug-in loop detectors are working properly and appropriate loops are installed on the loop input terminals.

OPERATOR HAS TROUBLE

1) Operator’s manual release is engaged

 

➤ Make sure the the unit’s manual release is not engaged. The unit’s

LEARNING THE MOTOR

 

 

 

manual release, when engaged, will not allow the entrapment sensor

 

 

 

 

 

 

to provide feedback to the GL board when the operator is moving.

 

 

 

 

 

PROGRAMMING CHANGES

 

 

 

➤ If the switch S1-1 is in the on position, any subsequent programming

changes will not affect the gate. To make programming changes,

 

 

 

 

 

 

switch S1-1 off, make desired changes, and then switch S1-1 on.
