Frequency converter
The frequency converter supplies an output frequency proportional to the flow rate. The
final value can be set at the factory according to customer requirements and can be up to
2 kHz.. If no end frequency is specified by the user, the standard frequency range is 0...2
kHz = 0...measuring range end.
However, the permanently programmed end value can be assigned to any flow value on
site.
Programming:
1. Set the maximum 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 Sensor is now adjusted to
0...max. Output frequency = 0...when programming the set flow rate.
3. After programming, pin 2 (or the white strand) must either remain unconnected or
be connected to 0 V.
