- (Negative) circuit input starts with:
• Battery negative ground inputs at the A1 Control Board and A2 Speed Control Ground terminals.
• The A1 control board solution button enabled.
• A negative voltage output from the A2 speed controller’s (pin #6) RED/BLK wire to the A1 control board RED/BLK
wire (terminal J1-5). Note that the A2 speed control Brake output (pin #6) occurs whenever the R1 direction throttle
pot is moved off its neutral setting.
A negative voltage output from terminal J1-6 GRN/BLK wire is direct to the M1 Solution Pump turning it on to allow
ow to the L1 and L2 Solenoids. Note that the voltage should be the same when one or two nozzles are actuated. The
voltage is a PWM signal at 10KHz.
