close (or open), then the problem is in the activating
device. Repair or replace the device.
Problem: The radio controlled opener does not open
the gate.
Solution:
Check the light on the front of the remote transmitter. It
should illuminate when you signal the gate. If it does not
illuminate and if the batteries are okay, repair or replace
the transmitter.
Verify that the wiring for the radio controlled device is
correct.
Check the wiring for the antenna and correct it if
necessary.
Check DL1 and DL2. One should illuminate when the
transmitter button is pressed.
Determine if the fault is in the receiver by temporarily
connecting a push button device across the appropriate
terminals. If such a push button device opens the gate,
repair or replace the receiver.
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.
Increase the bypass pressure in small
1
/
4
turn increments
to see if the hydraulic system needs more pressure.
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.
DL4 or DL5 should illuminate 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.
If the motor is running, insure that the bypass valves are
correctly adjusted. Increase the bypass pressure in small
1
/
4
turn increments to see if the hydraulic system needs
more pressure.
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 motor run 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
select a time that is just longer than the opening time.
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 by cycling the
gate (opening and then closing) 10 times and pausing for
a couple of minutes between cycles.
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.
