The EP-1000 will auto-detect any standard a 3-wire potentiometer. Any value from 0-5k

to 0-100k can be used. Reverse potentiometers (5-0k or 10-0k, for example) may also be

used, but wires number 6 and 4 must be reversed. Most two-wire potentiometers (such

as the Curtis PB-5 or PB-6) can also be used if you connect a wire from the third

(unconnected) terminal of the potentiometer to the third terminal on the EP-1000's throttle

input (pin #6). To do this, you must first open the potentiometer's enclosure to gain

access to the terminals and solder a wire to the unused potentiometer terminal.

All EPC brand potentiometers are 3-wire, and come with a 6-pin EPC harness pre-

installed. Due to their accuracy and high quality construction, we strongly recommend

using only EPC potentiometer units with this controller. Low quality potentiometers can

result in poor motor speed control, uneven throttle response, and often have a very short

lifespan.

Although an improperly connected potentiometer will not damage the controller itself, it

could cause the controller to apply full power to the motor. This condition will cause the

motor to operate at an unsafe speed, which could damage or even destroy the motor.

Care should be taken not to power up the controller until proper installation of the

potentiometer is verified. A diagnostic device (such as a duty cycle meter) can be used to

show power output before connecting your motor. In some cases, a dummy load (such

as a heater or light bulb) can be

used in place of the motor, as long

as the device is rated for the line

voltage that you are using.
