Operating Instructions for analog transmitter MONITOR
Operating Instructions for analog transmitter MONITOR
-2- -3-
The device has a short-circuit proof and reverse
polarity protected switching output (Push-Pull). Analog
output 4...20 mA or 0…10 V is offered concurrently.
Programming is done with a magnetic clip through the
IP 67 enclosure. The MONITOR-electronics linearize
and convert the primary signal into a conventional
4…20 mA or 0…10 V output signal while providing
a flexible switch at the same time. Linearization and
calibration are done automatically.

6 Programming
The calibration magnet, clipped into a groove on the
device, is used to program the switch point. After
calibration, the magnet may be returned to its grooved
seat or stored elsewhere, to protect the data entered.
The calibration point is marked on the label.

8 Technical specifications
Analog output
4...20 mA or 0...10 V (Please specify when ordering!)
Current output
max. load 500 Ω
Voltage output
max. current 10 mA
Switch output
1 short-circuit proof and reverse-polarity protected switch output
Alarm: low / cable break low / OK: high
Push-Pull output
The output is self-configuring and can be connected as PNP- or NPN-switch. The switch
contact is available as Min- or Max-contact. (Please specify when ordering!)
Load
max. 100 mA
Hysteresis (electronic)
2% full scale.
The position of the hysteresis is dependent on whether the contact is programmed as a
Min- or Max-contact.
Contact programmed as Min-switch: above Max-switch: below

Note
The sensor is configured to customer specifications. It is thus ready for immediate use
without programming! Please note that the MONITOR-electronics is calibrated to the flow
sensor and can not be replaced without recalibration! Refer also to the data sheets and
operating instructions of the respective flow sensor.
