8.3 Recommended settings for diagnostic limit values
In the "Diagnostics / Diagnosis Control / ..." menu, limit values for the diagnostic values can be
specified.
In order to simplify their setting, recommendations for the individual limit values are shown here.
The values indicated are only intended as a rough guide and may need to be adapted in line
with on-site conditions.
8.3.1 Limit values for the coil resistance
Coil resistance monitoring is switched off (factory default).
Monitoring can be switched on in the "Diagnostics / Diagnosis Control / Sensor
Measurements" menu.
Parameter Factory setting
Coil R. Min Alarm 0 ohms
Coil R. Max Alarm 1000 ohms
The coil resistance depends on the fluid temperature T
medium
and the ambient temperature.
