10 DI3/OC1
Digital input/output, configurable.
Open collector: Maximum 24 V resistive or inductive.
4
With standard product delivery,
analog inputs 1 and 2 are used
by the sensor.
AI1
Analog input:
0-20 mA or 4-20 mA
0.5-3.5 V, 0-5 V or 0-10 V.
2 DI1
Digital input, configurable.
Digital input 1 is factory-set to be start or stop input where an open circuit
results in stop. A jumper has been factory-fitted between terminals 2 and
6. Remove the jumper if digital input 1 is to be used as external start or
stop or any other external function.

6.3.2 Signal relays
The motor has two outputs for potential-free signals via two internal
relays. You can set the signal outputs to Operation, Pump
running, Ready, Alarm and Warning.
The functions of the two signal relays appear from the table below:
Grundfos Eye is off
The power is off.
Operation Pump running Ready Alarm Warning Operating mode
-
Grundfos Eye is rotating green
The pump or motor runs in Normal mode in open or closed loop.
