Installation and setup manual
7. Push button on teach adapter for 1 second
→ 0 % displacement value is defined [4 mA],
LED on sensor flashes 4 times per second
Attention: After teaching 0 % displacement
value the sensor is given an undefined signal
between 4 and 20 mA.
8. Set the nominal value for the pump displace-
ment to 100 % so that the pump is in max
displacement. The displacement of the
pump can be checked with the help of a flow
measuring device. The maximum displace-
ment is reached, if the displacement / flow
does not further increase, even when the
input command is still raised.

9. Push button on teach adapter for 1 second →
100 % displacement value is defined [20 mA],
LED on sensor emits a permanent light signal.
10. Disconnect teach-adapter and sensor and
reconnect sensor with electronic control
module.
Attention: The teach process needs to be fin-
ished within 2 minutes. Otherwise the sensor will
reset to the previous setting.
Note: If the teach button is pressed for 8 sec-
onds, all settings are deleted, and the sensor is
reset to the factory settings.
