7.6.3 Temperature monitoring
Each (optional) temperature module provides
two channels
for temperature monitoring.
Used for Pt100 measurement
•
Up to 2 limit values
•
Short circuit and wire / sensor breakage monitoring
Used for PTC monitoring
•
Monitoring the PTC response temperature
•
Short circuit monitoring
Usage of the determined states
… Activating a
when an alarm limit is violated (Pt100) or the response temperature is
reached (PTC), a short-circuit or a wire / sensor breakage (Pt100) occurs
… as source for digital outputs
… Entry into the alarm list when any state change occurs
… the present temperature for Pt100 measurement can also be output via analog outputs
State of temperature monitoring in the instantaneous values menu, PTC on the left, Pt100 on the right
