Drive Motor System Function
See Figures 17 and 18. With the Key Switch S1 closed, the BRN wire inputs 24V to the A2 speed controller (pin
5-KSI) to make its internal control circuits operational (powering it up). The CB2 circuit breaker (30-Amp) supplies the
positive load circuit voltage input to the B+ controller terminal (WHT/YEL wire). The black wire from the battery negative
standoff supplies the negative input to the B- controller terminal.
Moving the 5K Ohm R1 pot off its centered balanced neutral setting of approximately 2500 Ohms, activates the
operator input to the speed control. Forward or Reverse movement of the drive paddle rotates the pot shaft, and the
pot’s variable resistance values are changed which generates the internal voltage signals (0-5 Volts) needed for the
controller’s output operation. These control board voltage input signals are what energizes the Forward and Reverse
directional relays, which then select the motor polarity and nal voltage level outputs at the M1 and M2 terminals.
When the operator turns the R2 speed limit Pot from min. to max. (CW) this causes an input resistance relationship
change between the pot high (+) and wiper terminals (high to low Ohms), thus increasing the maximum wheel motor
operating speed range. Turning the knob (CCW) increases the resistance and the motor speed range is reduced.
