VACUUM MOTOR CIRCUIT OVERVIEW
Auto Mode (See Figure 2)
+ Positive battery circuit inputs and outputs
Inputs:
• A Solenoid circuit control coil (+) voltage input to control board E1 connector J2 pin #’s 6 & 7 (wire colors Brn/Yel). Note: This input voltage
supplies all the machine’s accessory and solenoid coil circuits (solution, vacuum, brush, headlight, warning beacon etc.).
• A closed S1 key switch supplies (+) input voltage to the E1 terminal J2 pin #10 (wire Brn). This powers up (turns on) the control board’s processing
logic functions.
• A closed S2 operator safety seat switch enables the starting of the entire automatic machine scrubbing system functions. Its E1 terminal
connection is J4 pin #11 (wire Orn).
Outputs:
• A control board E1 battery (+) voltage output from the solenoid accessory terminal connection J2 pin #8 Wht/Brn wire completes the positive
voltage to the vacuum solenoid coil.
- Negative battery circuit inputs and outputs
Inputs:
• A main (-) battery ground input for the control board E1 terminal J4 pin #8 wire Blk. This supports the operation of the board’s processing logic
functions with the above mentioned S1 (+) key switch input.
• A battery ground input for all the (E1 boards) negative solenoid coil output circuits. Its E1 terminal connection is J2 pin #5 (wire Blk).
Outputs:
• A battery ground output from the E1 control board terminal connector J2 pin #2 wire Gra/Blk. This control board output completes the K2 vacuum
solenoid coil circuit (Pos. & Neg.) and pulls in the vacuum solenoid load contact K2 making the vacuum motor(s) M5 & M6 run. This occurs
every time the throttle is moved off its neutral setting and the vacuum switch is on. Note: When the throttle is returned to neutral the vacuum
will remain on for 10 seconds and the indicator light will fl ash green.
