Option - PMU for

analog output

U1, U2, U8 and I1

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.

Description of Output Options

Diagnostic on analog

outputs

Error signal for

SSI output

If the sensor cannot detect a magnet the position value will assume the maximum value

(0xFFFFFFF).

Alarm_HIGH

(standard)

Alarm_LOW

(.../U)

Alarm_HOLD

(.../H)

U1

—

keeps last valid state

U2

keeps last valid state

U8

keeps last valid state

I1

1,5 ... 2 mA

(Order code

I1/U)

keeps last valid state

Behaviour of the analog signal output in case of error

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.
