CENTRAL COMMAND I
If there is not battery voltage (+/- 1.5 volts) repair the ground wire to the coil of the
vacuum motor solenoid.
With a volt meter measure from the negative buss bar to the left load terminal on the
contactor.
If there is battery voltage go to the next step
If there is not battery voltage there is a battery or battery cable problem.
Measure from the negative (-) buss bar to the right side load contact on the solenoid.
If there is battery voltage (+/- 1 volt) go to the next step
If the voltage is less than 1 volt below battery voltage replace the solenoid.
Measure for voltage at both posts of the vacuum motor circuit breaker.
If there is battery voltage (+/- 1 volt) on both posts go to the next step.
If there is NOT battery voltage (+/- 1 volt) on both posts replace the circuit breaker
Check the wiring from the breaker to the vacuum motor and the vacuum motor to ground.
RIDER MACHINES
TYPE 6 Central Command I Rider squeegee actuator
The CCI rider squeegee actuator limit switch set up is the most complicated limit switch set
up we have. It has 3 different states and this is how each of them works.
State 1: Forward/Reverse switch “FORWARD” Squeegee switch “OFF”
Positive power is sent from the squeegee rocker switch out the green wire on the squeegee
rocker switch to the front terminal of the “up” limit switch, thru the switch, out the green wire
to the yellow wire of the actuator. Negative power is sent out the white wire to two places.
The first is along the white wire to the actuator motor and along the other white wire to the
reverse diode bridge. The actuator retracts until it contacts the “UP” limit switch which then
opens stopping the actuator motor.
State 2: Forward/Reverse switch “FORWARD” Squeegee switch “ON”
Negative power is sent from the squeegee switch out the orange wire to the back terminal
of the down limit switch. Positive power is sent out the white wire to two places, the first
being the white wire that connects to the red wire on the squeegee actuator. This will make
the actuator extend until it contacts the rear ”down” limit switch. The second place it sends
power to is the positive terminal on the reverse diode bridge which stops voltage from flow-
ing through when the squeegee switch is turned on. When the squeegee actuator drops the
squeegee and reaches its end of travel it depresses the “down” limit switch. The switch then
delivers the power from the actuator thru the “Hella” vac relay on the pink wire and then out
of the relay on the white wire and to pin #5 on the vacuum timer assembly.
State 3: Forward/Reverse switch “REVERSE” Squeegee switch “ON”
Positive power is sent from the squeegee switch out the green wire thru the “UP” limit switch
out to the yellow actuator wire. Negative power is sent through the squeegee switch out the
white wire to the red wire on the actuator. When the actuator extends all the way the “UP”
limit switch opens and turns off the actuator motor.
