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:
