ELECTRICAL SYSTEM
Scrub ON/Pressure-increase Switch (G):
This switch is used to control the output to the scrub deck 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 actuator power indicator (battery yellow)
(L)
should be off and the actuator
direction indicator (battery green)
(M)
will be off. If the power indicator is flashing, this indicates that the control is sensing current flow through
the actuator (control failure or wiring problem).
When the output is in state 2, the actuator output is turned on. The actuator power indicator (battery yellow)
(L)
should be on or flashing and the
actuator direction indicator (battery green)
(M)
will be on. The power indicator will be on steady if the control senses current flow through the
actuator. It will flash if no actuator current flow is sensed (actuator at limit, actuator failure, control failure, or wiring problem).
When the output is in state 3, the actuator output is turned off. The actuator power indicator (battery yellow)
(L)
should be off and the actuator
direction indicator (battery green)
(M)
will be on. If the power indicator is flashing, this indicates that the control is sensing current flow through
the actuator (control failure or wiring problem).
When the output is in state 4, the actuator output is turned on. The actuator power indicator (battery yellow)
(L)
should be on or flashing and the
actuator direction indicator (battery green)
(M)
will be off. The power indicator will be on steady if the control senses current flow through the
actuator. It will flash if no actuator current flow is sensed (actuator at limit, actuator failure, control failure, or wiring problem).
Vacuum Switch (E):
This switch is used to turn the vacuum motor on and off. Pressing and releasing this switch will alternately turn the vacuum motor on and off. The
indicator
(F)
provides the following status information:
Off
- Vacuum output is off and there is no vacuum motor current flow.
Green
- Vacuum output is on and there is normal vacuum motor current flow.
Flashing green
- Either the vacuum motor output is off and the control is sensing vacuum motor current flow (control failure, shorted contactor,
or wiring problem) or the vacuum motor output is on and the control is not sensing any vacuum motor current flow (open contactor, control failure,
or wiring problem).
Solution Switch (D):
This switch is used to turn the solution solenoid on and off. Pressing and releasing this switch will alternately turn the solution solenoid on and
off. The indicator
(C)
provides the following status information:
Off
- Solenoid output is off.
Green
- Solenoid output is on.
