Curtis PMC 1204X/1205X/1209/1221 Manual
should determine by experiment the proper resistor value to give the desired speed
reduction.
: with reduced speed operation, only top speed is reduced; full
(
NOTE
power is maintained for starting at low speeds.)
Unlike resistor controllers, Curtis PMC controllers operate efficiently in the
reduced speed mode, because little power is lost through the controller.
Electronic Throttle Wiring
Curtis's electronic throttle, ET-XXX, is wired as shown in Figure 15. It requires
a controller with the optional 0–5V throttle input.
