Circuit Overview
Solenoid Valve Circuit
The positive terminal (white/brown wire) of the solution solenoid receives +24V battery power through key
switch and E-stop switch. The negative terminal (violet/black wire) of the solution solenoid is connected to
the Main Machine Controller at J3-11. The solenoid is active when the controller forces the J1-11 terminal
to Battery Negative. The solenoid output is inhibited unless the machine is in motion or pre-wetting is called
for.
Detergent Pump
The detergent pump is a small reversible diaphragm pump. The polarity of the pump is reversed to cycle the
pump faster. The ow rate of the detergent pump is controlled by PWM at varying rates depending on the
desired mixing ratio.
