OPERATIONAL OVERVIEW OF THE SOLUTION PUMP & SOLENOID FUNCTIONS
Solution Delivery in the Auto Mode
Starts with the operator turning on the main power key switch then selecting either the maintenance or restoration mode switch.
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).
• 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 allows 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.
Negative (-) battery circuit inputs and outputs
Inputs:
• A main (-) battery ground input for the control board E1 terminal J4 pin#8 BLK wire. This supports the operation of the boards processing logic
functions.
• Battery ground supply input for all the (control boards) negative output coil 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 #3 wire Vio/Blk for the L1 solenoid or J2 pin #4 wire Wht/Grn for
the L2 solenoid. This controlled output turns on and off the L1 & L2 solenoid coils that stops and starts the solution
fl ow through the valve body
selected. This occurs every time the throttle is moved off its neutral setting into forward.
Solution Delivery in the Accessory Mode
Starts with the operator only having to turn on the main power key switch.
Positive (+) battery circuit inputs and outputs
Inputs:
• Accessory/solenoid circuit (+) voltage input to control board E1 connector J2 pin #’s 6 & 7 (wire colors Brn/Yel).
• 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.
Outputs:
• A control board E1 battery (+) voltage output from solenoid accessory terminal connection J2 pin #8 Wht/Brn wire. This feeds the pump
pressure switch S3, which is built into the pump M4. The pressure switch is normally closed and will open when the head pressure reaches
its cutout limit of 100 PSI. When the operator depresses the accessory wand trigger valve the trapped solution pressure drops below 100 PSI
and the pump will run.
Negative (-) battery circuit inputs
• A main (-) battery ground input to the control board E1 terminal J4 pin #8 BLK wire. This completes the circuit support for the operation of the
board’s processing logic functions.
• A direct battery ground input for completion of the M4 pump circuit
