Input demand

There are two methods of setting the input demand using the

PerfectSpeed® User Interface box.

Configuration scenarios

This section provides examples of different configurations and

briefly describes how the motor operates under those conditions.

Operating parameters

Speed will change linearly based on the On-Board Potentiometer

or remote 0V to 10V DC signal. The graph below illustrates the

operation of a motor adjusted with the On-Board Potentiometer.

At 0.5V DC signal, the motor will come on at 30 0 rpm and

ramp linearly to 18 0 0 rpm for ECM series circulators.
