WHEEL DRIVE SYSTEM
GENERAL FUNCTIONAL OVERVIEW
See Figures 1 & 2. A 700-watt .9 HP (permanent magnet) 36V motor/gear transmission combination wheel (M1) unit is used to propel all
machines. A Curtis model 1228 PMC solid state speed controller (A1) regulates (outputs) the variable speed Fwd/Rev wheel drive motor
functions. The controller unit is located underneath the front of the operator seat, behind the electrical access panel. The potentiometer R1
mounted to the operator’s foot pedal, inputs to the (A1) controller the machine operator’s desired speed and directional demands.
DRIVE MOTOR SYSTEM CONTROLLER FUNCTION OVERVIEW
See Figure 1. To make the A1 speed controllers internal control circuits operational (power it up) the three switches S1 (key), S2 (seat) and S10
(emergency stop knob) must be closed. This circuit inputs a positive (+) 36V to the A1 speed controls pin terminal #5 (*KSI). The CB2 circuit
breaker 40 Amp supplies the positive high current (load) circuit input to the B+ controller terminal (Grn/Wht wire). The black wire from the negative
(-) battery standoff supplies the battery ground input to the B- terminal for both the control and load circuits.
See Figure 3. Depressing the foot pedal in either Fwd or Rev will move the 5K Ohm (R1) potentiometer shaft off its centered balanced (neutral)
setting of approximately 2500 Ohms. With this pot shaft movement the pot’s resistance value changes which generates a variable voltage signal
(0-5 volts). These control board voltage input signals are what energizes the Fwd & Rev directional relays, which selects the motor polarity and
also switches the battery voltage On and Off (**PWM) which varies the motor speed.
*KSI: Key Switch Input
**PWM: Pulse Width Modulation, also called “chopping” is a technique that switches battery voltage to the motor ON and OFF very quickly,
thereby controlling the speed of the motor.
DRIVE MODE SELECTION OPERATION OVERVIEW
The A1 speed Controller allows operation in two distinct modes: mode 1 (M1) & mode 2 (M2).
Mode 1 (M1) is the transport speed range and is automatically selected when the burnishing system is OFF (deck up). This allows maximum
variable vehicle speed operation.
Mode 2 (M2) is the reduced slower burnishing speed range and is automatically selected when the burnishing mode is ON (deck down).
Note: The maximum machine drive wheel speed setting for the two drive modes 1 & 2 can be changed by using the Curtis handheld programmer.
Reference the Curtis programmer instructions found in the electrical system manual section to change speed settings from their original factory
speci
fi cations.
