620/640 Operator And
624BLD Control Panel Installation Manual
T
ROUBLESHOOTING
WARNING!
Before you do any work on the control panel, be sure to
turn off the main power.
NOTE:
Any control panel specific information in the following applies to the 624BLD control panel only.
PROBLEM:
The beam is closed and won't open in
response
to an activating signal.
SOLUTION:
Make sure the hydraulic operation of the barrier beam
is engaged: The Manual Release key should be turned
clockwise until snug.
The OPEN indicator LED should illuminate when you
send an activating signal. If it does not, temporarily
short terminals 5 and 10. If the short causes the beam
to open, then the problem exists in the activating
device itself.
If you have no stop device wired to terminal 8, then
make sure you have a jumper installed between
terminals 8 and 10 on the control panel. The STOP LED
should be on.
The FCC indicator light on the control panel should not
be illuminated. If it is illuminated, then the gate is not
fully closed. Adjust the position of the closing limit
switch plate.
Try increasing the opening hydraulic pressure in small
increments by turning the opening bypass valve screw
(the green valve) clockwise.
Verify that you have the correct compression spring
for your barrier beam. If you have the correct spring,
check that the spring will hold the beam in any
position during manual operation. If the spring doesn't
hold the beam in any position, try tightening the
compression spring until the beam is held and then
recheck the hydraulic operation of the beam.
PROBLEM:
The beam is open and won't close in response to an
activating signal.
SOLUTION:
Check the LEDs on the control panel. The FCA light
should be off, and the FSW, STOP, FCC, and
EMERGENCY lights should be on if the FCA light is on,
then the gate is not fully opened. Move the opening limit
switch plate closer to the opening limit switch
.
If you have no reversing devices installed and you are
operating in A or E mode, make sure you have a jumper
installed between terminals 7 and 19. (The FSW light
should be on.)
If the FSW light is off, some reversing device you have
installed is being continuously triggered and is preventing
the beam from closing. Check your reversing devices.
If your activating device has two buttons—one for
opening/closing and one for stop—and you are operating
in P mode, then make sure you have a jumper between
terminals 2 and 5.
If you have no stop device wired to terminal 8, then make
sure you have a jumper installed between terminals 8 and
10 on the control panel.
If you have no emergency device wired to terminal 9, then
make sure you have a jumper installed between terminals
9 and 10 on the control panel.
Increase the pressure of the closing bypass valve (the red
valve) by turning the screw clockwise in small increments
to see if the beam needs more hydraulic pressure for the
closing direction.
PROBLEM:
The beam is half opened and will neither open nor
close in response to the activating device.
SOLUTION:
The barrier may be in jam status because something or
someone has physically prevented the beam from
opening or closing. Reset the barrier and then try sending
another activating signal.
Check the FSW indicator light. It should be on. If it is not
illuminated, then check the wiring on your safety devices.
