Function principle of alarms / relays Alarm / Relay x deactivated, instantaneous value, min/max-value, hold-value,...
  • Page 32 7. Alarms / Relays Quiescent current By quiescent current the alarm S1-S2 is on below the threshold and switched off on reaching the threshold. Switching-on delay The switching-on delay is activated via an alarm and e.g. switched 10 seconds after reaching the switching threshold, a short-term exceedance of the switching value does not cause an alarm, respectively does not cause a switching operation of the relay.
  • Page 33 8. Sensor alignment offset / final value 8. Sensor alignment offset / final value The device is equipped with a semi-automatic sensor calibration ( ). A switching output operates the trimming resistor, which exists in some sensors. An adjustment of offset and final value takes place, after which the sensor can be used directly. Depending on parameterisation, the calibration can be realized via the 4th key or via the digital input.
