ELECTRICAL SYSTEM
Normal Scrub Switch (26):
This switch is used to control the output to the pad/brush lift actuator. Pressing and releasing this switch will cycle the actuator output through 4
states. These are:
1 - output off, direction = up
2 - output on, direction = down
3 - output off, direction = down
4 - output on, direction = up
When the output is in state 1, the actuator output is turned off. The pad actuator up indicator
(46)
will be lit and the normal scrub indicator
(35)
should be off. If the indicator
(35)
is flashing yellow, this indicates that the control is sensing current flow through the actuator (shorted output driver,
control error). If the up indicator
(46)
is flashing, this indicates that the pad/brush lift system is currently selected. This means that it is possible
to momentarily activate the actuator output using the horn switch
(42)
. This can be used to jog the actuator to allow precise positioning of the
actuator. NOTE: the actuator can only move in this situation if it is not at its up limit.
When the output is in state 2, the actuator output is turned on. The pad actuator down indicator
(48)
will be lit and the normal scrub indicator
(35)
should be green or flashing green. The indicator will be a steady green if the control senses current flow through the actuator. It will flash green
if no actuator current flow is sensed (actuator at limit, open circuit, or open output driver). The horn switch has no effect in this state.
When the output is in state 3, the actuator output is turned off. The pad actuator down indicator
(48)
will be lit and the normal scrub indicator
(35)
should be off. If the indicator
(35)
is flashing yellow, this indicates that the control is sensing current flow through the actuator (shorted output driver,
control error). If the down indicator
(48)
is flashing, this indicates that the pad/brush lift system is currently selected. This means that it is possible
to momentarily activate the actuator output using the horn switch
(42)
. This can be used to jog the actuator to allow precise positioning of the
actuator. NOTE: the actuator can only move in this situation if it is not at its down limit.
When the output is in state 4, the actuator output is turned on. The pad actuator up indicator
(46)
will be lit and the normal scrub indicator
(35)
should be green or flashing green. The indicator will be a steady green if the control senses current flow through the actuator. It will flash green
if no actuator current flow is sensed (actuator at limit, open circuit, or open output driver). The horn switch has no effect in this state.
Heavy Scrub Switch (27):
This switch is used to control the output to the squeegee lift actuator. Pressing and releasing this switch will cycle the actuator output through 4
states. These are:
1 - output off, direction = up
2 - output on, direction = down
3 - output off, direction = down
4 - output on, direction = up
When the output is in state 1, the actuator output is turned off. The squeegee actuator up indicator
(47)
will be lit and the heavy scrub indicator
(36)
should be off. If the indicator
(36)
is flashing yellow, this indicates that the control is sensing current flow through the actuator (shorted output
driver, control error). If the up indicator
(47)
is flashing, this indicates that the squeegee lift system is currently selected. This means that it is possible
to momentarily activate the actuator output using the horn switch
(42)
. This can be used to jog the actuator to allow precise positioning of the
actuator. NOTE: the actuator can only move in this situation if it is not at its up limit.
When the output is in state 2, the actuator output is turned on. The squeegee actuator down indicator
(49)
will be lit and the heavy scrub indicator
(36)
should be green or flashing green. The indicator will be a steady green if the control senses current flow through the actuator. It will flash
green if no actuator current flow is sensed (actuator at limit, open circuit, or open output driver). The horn switch has no effect in this state.
When the output is in state 3, the actuator output is turned off. The squeegee actuator down indicator
(49)
will be lit and the heavy scrub indicator
(36)
should be off. If the indicator
(36)
is flashing yellow, this indicates that the control is sensing current flow through the actuator (shorted output
driver, control error). If the down indicator
(49)
is flashing, this indicates that the squeegee lift system is currently selected. This means that it is
possible to momentarily activate the actuator output using the horn switch
(42)
. This can be used to jog the actuator to allow precise positioning
of the actuator. NOTE: the actuator can only move in this situation if it is not at its down limit.
When the output is in state 4, the actuator output is turned on. The squeegee actuator up indicator
(47)
will be lit and the heavy scrub indicator
(36)
should be green or flashing green. The indicator will be a steady green if the control senses current flow through the actuator. It will flash
green if no actuator current flow is sensed (actuator at limit, open circuit, or open output driver). The horn switch has no effect in this state.
