WARNING! Before you do any work on the control panel,
NOTE: Any control panel specific information in the following applies to the 455 D control panel only.

.
ACTIVATING SIGNAL
S :
OLUTION
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.

S :
OLUTION
Make sure that the motor is running in the right
direction, and make
mechanism has fully engaged the hydraulic system.
P : T
ROBLEM HE GATE OPENS BUT DOES NOT CLOSE
S :
OLUTION
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.

CLOSE
S :
OLUTION
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.

)
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.

S :
OLUTION
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.
