The loop impedance must be less than 300 ohms.
Do not short the 4-20mA output loop. Doing so will cause the pump to shut off and may damage
the pump.
To ensure proper signal output, always calibrate the output signal.
Connection Terminals
• Connect load positive to 4-20mA OUT (+), position #15 on the bottom row.
• Connect load common to 4-20mA OUT (-), position #14 on the bottom row.

This signal corresponds proportionally to pump speed with 0% pump
speed equaling 4.0mA and 100% pump speed equaling 20.0mA. The
signal response is not adjustable.

The pump sources the voltage for the output
signal loop at 24VDC. The pump will control the

magnitude of current on the loop (from 4 to

20mA) according to the speed that the pump is
running at. The maximum loop impedance (load
on the output signal loop) is 300 ohms, which
–
includes the load plus any resistance due wire
length, connections, etc.
