When an alarm is shown, the display will also turn red and the name of the measuring point will be inverted.
Additionally, the date and time are also shown on the RMS Display, all data is collected from the Web service.
1.5 Power Supply
All input modules (data loggers) have the following three power supply variants:

Two 3.6 V lithium thionyl chloride AA batteries
The power supply of the batteries suffices to carry out measurement and data storage and to operate
the wireless interface. Devices with an Ethernet interface must also have one of the following power
supplies. IMPORTANT: The RMS Display is not battery powered!

24 VDC ±10 % / <100 mA
2 via terminals (V+ / V-)

Power over Ethernet (PoE), per standard IEEE 802.3af, Class 1
Note on the batteries:
The AA batteries are lithium thionyl chloride batteries available in the industrial trade. All RMS input modules
are designed for this type of battery. Only batteries of the same type or with identical characteristic values may
be used as replacement batteries.
