VACUUM MOTOR CIRCUIT OVERVIEW
There are two vacuum switch operator modes, Auto vacuum for machine transport extraction use and manual On/Off stationary
optional accessory uses. Note: see the
Know Your Machine section in this manual for a detailed description of the vacuum operation
modes.
Vacuum motor system function in the Auto Mode:

Vacuum motor system function in the Auto Mode:
Starts with the operator turning on the main power key switch then selecting either the maintenance or restoration mode function
switch.
Positive (+) battery circuit inputs and outputs
Inputs:
•••••
See Figure 2. 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 flash green.
