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.
1. With the CBC-802 control still unplugged
from the socket, apply the 120 VAC to the
control socket.
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.
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.
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.
3. Once test is complete, turn off AC power.
Note: Voltages other than zero indicates problems.
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.
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.
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.
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.
8. This completes the installation of the
CBC-802.
