Programming of the start and end value by the customer:
The option PMU allows to program the start value and the end value of the output range
by a programming signal SPAN/ZERO available at the connector. This Signal SPAN/ZERO
must be connected with GND via a push button, then position magnet of the sensor must
be moved to the start resp. end position. Pushing the button between 2 and 4 seconds sets
the actual position as start position, pushing the button more than 5 seconds sets the actual
position as end position. The values will be stored and are available after switching off the
sensor.
To reset the sensor to the factory values the button must be pushed for longer than two
seconds when the sensor is switched on.

In case of error (magnet missing or outside the measuring range) the analog output signal
will assume a state according to the following options:
Alarm_HIGH
The output voltage resp. the output current is at HIGH level (overrange).
Alarm_LOW
The output voltage resp. the output current is at LOW level (underrange).
Alarm_HOLD
The output voltage resp. the output current will keep the last valid state.

If the sensor cannot detect a magnet the position value will assume the maximum value
(0xFFFFFFF).
