Siemens 6MD86 User Manual

Under the following conditions, the Default temperature will be set as ambient temperature:
•
A temperature sensor for measuring the ambient temperature is not connected.
•
The temperature measurement is interrupted and the measured temperature value is less than the
Default temperature.
Siemens recommends using the default setting.
Parameter: Minimal temperature
•
Default setting (_:117) Minimal temperature = -20°C
If the measured ambient temperature drops below the preset value, the set value will be assumed as the
ambient temperature. If the overload protection works with a prespecified outside temperature, and this
temperature drops below the value set in the Minimal temperature parameter, the Minimal tempera-
ture can also be used.
