PROBLEM: THE GATE DOES NOT RESPOND TO AN

ACTIVATING SIGNAL.

SOLUTION:

You should have at least one operator wired to

terminals 1,2 and 3.

Be sure that you have the motor start capacitors wired in

terminals 2 and 3, 5 and 6 with the directional leads.

Be sure that the torque/force setting is at the maximum

setting of 50 in programming.

Verify that the LEDs FSWOP, FSWCL, and the STOP are

illuminated. If they are not illuminated, be sure that you

have closed circuits in the stop and reversing inputs.

Verify that your activating device works properly. OP_A

should illuminate when you signal the gate to open. If

OP_A does not illuminate when you signal the gate, then

the problem may be in your activating device. Short

across terminals 9 and 14. If the short causes the gate

to open, then the problem is in the activating device.

Repair or replace the device.

PROBLEM: THE GATE DOESN'T OPEN (OR CLOSE)

THOUGH THE MOTORS ARE RUNNING.

SOLUTION:

Make sure that the motor is running in the right

direction, and make sure the Manual Release

mechanism has fully engaged the hydraulic system.

PROBLEM: THE GATE OPENS BUT DOES NOT CLOSE.

SOLUTION:

Make sure you have selected the desired operating

mode.

Verify that the reversing devices are working properly.

FSWOP and FSWCL should be illuminated except when a

reversing device is triggered. If either does not

illuminate, then one of your reversing devices is

preventing the gate from responding to your signal.

Check your reversing devices.

If no reversing devices are installed, make sure a circuit

is installed between appropriate terminals.

PROBLEM: THE GATE DOES NOT FULLY OPEN (OR

CLOSE).

SOLUTION:

Increase the bypass pressure(s) to see if the hydraulic

system needs more pressure.

Check the operator's open/ close time selection. You

should set a time that is just longer than the rated

speed of your model of operator. For example, because

the 400 CBAC has a rated opening time of 17 sec, you

should set the time at 20 or 25 seconds.

Check to see that there are no obstructions in the path

of the gate or that the hinges are not binding.

PROBLEM: THE OPERATOR DOESN'T WORK

SMOOTHLY AND THE GATE JERKS AS IT OPENS AND

CLOSES.

SOLUTION:

Check the oil level in the operator.

Make sure the Manual Release mechanism has fully

engaged the hydraulic operation of the operator.

Bleed the air from the hydraulic system. (See page 11).

Make sure that a flexible gate leaf is not the problem. If

the gate leaf flexes, then stiffen the gate or use a slower

operator.

PROBLEM: THE GATE DRIFTS OPEN OR CLOSE WHEN

THE MOTOR IS NOT RUNNING.

SOLUTION:

Remove the manual release valve, located next to the

pressure adjustment screws, with a 6mm hex key. Be

sure that the white ring and the o’ring are not damaged.

If not damaged, there may be internal damage and a

seal kit will be needed to rebuild the unit.
