Switching output
With the raid of the integrated sensor, the electronics receives a frequency signal propor -
tional to the flow rate and evaluates it. If the value falls below the set limit value, an alarm
signal is output and the yellow LED in the plug connection goes out.
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). Immediately after program-
ming, the sensor switches to alarm status. The alarm is cancelled as soon as the
flow rate has been increased to such an extent that the switching value plus 12 Hz
(=hysteresis) is reached.
3. After programming, pin 2 (or the white strand) must either remain unconnected or
be connected to 0 V.
