Installation and operation
Display of the status change on the multi-LED of the temperature/humidity sensor.
– The multi-LED lights red continuously for approx. 5 seconds while the average value of the meas-
EN
ured values is being determined.
– Continuous blue flashing: Communication over the CAN bus.
– Green flashing: When the measured value changes or, at the latest, every 5 seconds.
– Continuous orange flashing: The temperature/humidity sensor has the "warning" status. Fast
flashing: Upper limit value exceeded. Slow flashing: Lower limit value exceeded.
– Continuous red flashing: The temperature/humidity sensor has the "alarm" status. Fast flashing:
Upper limit value exceeded. Slow flashing: Lower limit value exceeded.
– Continuous red light: Invalid measured value.
If the installation is not successful: see Section 1.1.
Note:
Connection cables in various lengths can be obtained from Rittal.
5.3 Settings
Visit the CMC III PU web site to set or view the appropriate parameters of the associated sensor.
Note:
The "Offset" variable is only available from hardware version V0203 onwards.
Temperature sensor:
– Value: Currently measured temperature [°C]
– Offset: Offset value used to correct the measured temperature [°C]
– SetPtHighAlarm: Upper alarm limit value [°C]
– SetPtHighWarning: Upper warning limit value [°C]
– SetPtLowWarning: Lower warning limit value [°C]
– SetPtLowAlarm: Lower alarm limit value [°C]
– Hysteresis: Status message delay [%]
– Status: Current status of the temperature sensor taking account of the hysteresis
Humidity sensor:
– Value: Currently measured air humidity [%]
– SetPtHighAlarm: Upper alarm limit value [%]
– SetPtHighWarning: Upper warning limit value [%]
– SetPtLowWarning: Lower warning limit value [%]
– SetPtLowAlarm: Lower alarm limit value [%]
– Hysteresis: Status message delay [%]
– Status: Current status of the humidity sensor taking account of the hysteresis
