Start-Up
The following procedure may be used to check out the
socket and wiring installation prior to plugging in and
powering the CBC-802. This procedure will check for
any grounding problem and prevent the control from
being blown. To carry out this test, a digital voltmeter
set to measure AC voltage with a range of 250 VAC is
needed.
q
1. With the CBC-802 control still unplugged
from the socket, apply the 120 VAC to the
control socket.
q
2. Place one test lead of the meter to terminal
1 (hot side of 120 VAC input power)
and with the other test lead of the meter
measure to the other terminals of the
socket.
q
A zero volt reading should be observed between
terminal 1 and all other terminals except
terminal 5 which should measure the AC line
voltage to the socket.
q
A reading of other than (0) zero volts to any of
the terminals (except 1 to 5) indicates some
type of leakage or grounding condition
and MUST be removed or the control will
potentially be destroyed on power up.
q
3. Once test is complete, turn off AC power.

4. After completion of ground fault checks is
done and power off to the control socket,
insert the CBC-802 into the octal socket.
Note
: The socket is keyed, so control will only go in
one way.
q
5. With control installed in socket, apply power
to the CBC-802. On power up, the brake
output LED (Red) should be on, and the
brake should be energized.
q
6. Cycle the control between clutch/brake
channels and observe that the channel
output lights switch between brake and
clutch (Red LED to Green LED) and insure
brake and clutch are energizing properly.
q
7. Start the machine and allow unit to cycle.
Make any adjustment on anti-overlap
potentiometer while machine is running.
Adjust only enough to eliminate any
interaction from one unit turning off and
other unit turning on.
Note:
If time delay is set too high, a delay between
one unit turning off and other unit turning on will be
noticed. This could cause loss of control in machine
function momentarily.
q
8. This completes the installation of the CBC-
802.
