Analogue output
With the aid of the integrated sensor, the electronics receives a flow-proportional fre-
quency signal and converts it into an analogue output signal. A current signal 4...20 mA is
generated in the M7I version and voltage signal 0...10 V in the M7U version.
By default, the analogue output is set to:
4...20 mA (or 0...10 V) = 0...upper range value set.
This setting can be changed on site as follows:
Programming:
1. Set the setpoint frequency (= setpoint flow rate) in the system.
2. Apply a pulse of a least 0,5 s duration to pin 2 or white strand (with cable outlet)
e.g. by jumper to supply voltage or pulse from PLC). The electronics is now pro-
grammed so that the set flow corresponds to the maximum value of the analogue
output (20 mA bzw. 10 V).
3. After programming, pin 2 (or the white strand) must either remain unconnected or
be connected to 0 V.

High temperature connection
The high temperature connection for the HT version has a 30 cm remote electronics, for
media temperatures up to 150 °C.
