5.5 Alarm
ProfiLux 4 can monitor the currently measured value of a sensor and react in various ways in
the event of an excessive deviation.
Please first set whether the alarm should be active. If you selected Yes, please proceed as
follows:
 Determine the Maximum deviation of the actual value from the nominal value.
 Select whether you want to disable this control in the event of an alarm (Shut-off
control?).
Note for temperature sensors
The adjusted hysteresis also depends on when the cooling is active. The
switching-on point of the cooling also depends on the cooling difference
(see also Sensors-> Cooling difference) and can be calculated as follows:
T = nominal temperature + 5/6 * hysteresis + cooling difference
With a hysteresis of 0.2 °C, this results: T = Nominal temperature + 0.167 °C
+ cooling difference.
