Contact reliability
To ensure high switching reliability, we recommend a minimum load of:
AC / DC = 24 V, 20 mA

The sequential gap is specified in K in relation to the set point value of contact deck I.
Prefix - = switching prior to reaching the set point value,
Prefix + = switching after reaching the set point value.
Enter "0" for the sequential gap for a simultaneously switching version.

medium
ambient
temperature influence
When the ambient temperature on the switch head and/or the capillary deviates
from the calibration temperature +22 °C, a switch point offset occurs.
Higher ambient temperatures = lower switching point
Lower ambient temperature = higher switching point

If the operating temperature on the switch head deviates essentially from the ambient calibration temperature +22 °C,
this can be taken into account on request during adjustment against surcharge.
