35Service Manual – SC5000 04 - Control System
Output Test
The Output Test menu provides manual control of various system functions for troubleshooting purposes.
This permits devices to be operated even when prerequisite conditions are not met, such as permitting the
solution solenoid to be active without the scrub system active.
Horn: The horn is always connected to Bat+, and the Main
Controller switches the Bat- connection to activate the horn.
Backup Alarm: The backup alarm is always connected to Bat+,
and the Main Controller switches the Bat- connection to activate the
alarm.
Beacon: The beacon is always connected to Bat+, and the Main
Controller switches the Bat- connection to activate the lamp.
Solution Solenoid: The solution solenoid is always connected
to Bat+, and the Main Controller switches the Bat- connection to
activate the solenoid.
Detergent Pump: The detergent pump is actually a spring-loaded
solenoid that is energized and de-energized by the controller. When
energized, one output will be 12V and the other output will be 0V.
Right and Left Brush: These two screens allow On/Off control of
the brush motors. The additional 3 lines provide status on the motor.
Vacuum 1 and 2: These two screens provide Off/On power control
to the main vacuum and optional second vacuum motors. Pressing
the Up/Down arrow buttons cycle through the power options.
Squeegee Lift: The Squeegee Lift screen provides Up/Down/Off
control for the squeegee lift actuator. However, the actuator still
controls the upper and lower position limits mechanically, inside
the actuator body. Therefore, if the squeegee is already raised and
you issue the UP command, the actuator still will not move, because
the mechanical limit is already reached. Another effect that you
may notice is that the Output PWM will remain at 100%, but when
the lift reaches its limit, the current drops to zero.
Deck Lift
The Deck Lift screen provides Up/Down/Off control for the deck lift
actuator. However, the actuator still controls the upper and lower
position limits mechanically, inside the actuator body. Therefore,
if the deck is already raised and you issue the UP command, the
actuator still will not move, because the mechanical limit is already
reached. Another effect that you may notice is that the Output PWM
will remain at 100%, but when the lift reaches its limit, the current
drops to zero.
