| Power Supply | All input modules (data loggers) have the following three power supply variants: 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 mA1 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. Type of Battery \ |

RMS Data Logger
The data logger carries out measurements in a fixed interval, saves all measured data and sends it to the database by radio or Ethernet link. Should the connection be lost, the logger stores the data intermediately to protect data integrity and fills up the data gaps when the connection has been restored. The measurement parameters depend on the connected probe; two different parameters can be measured at the same time. The device has a battery so that logging of measured data is also ensured in the event of a failure in the external power supply.
The data logger provides the following basic functions:
Measured Parameters¶
Depending on the version, the RMS data loggers have different inputs. Devices with interchangeable probes (E2 connector) detect the measurement parameter of the probe automatically. The following table lists the main types:

RTCC (Real Time Clock Calendar)¶
Data Logging and Measurement Interval
Indicator and Button
| Important: If the RMS wireless device is offline for a longer period of time, then this may cause for the wireless module to be sent into failure mode. This happens when a very low power supply is supplied to the device. Once the wireless module is in failure mode, it cannot be resuscitated. Once the wireless module has failed, the device's LED will blink differently to any way that is described in the manual. Recommendation: Please remove the batteries if the user anticipates keeping a wireless device disconnected for a longer period of time. |

Battery¶
The batteries serve to supply the device with power in the event of a failure in the external power supply. The functionality of the device is restricted in battery mode. The device continues to measure and records all data in the internal memory. The device cannot communicate via the Ethernet interface, but the wireless interface works normally.
Lithium batteries of the type AA with 3.6 V are used, per the device description. Make sure they are inserted correctly. The poles are marked on the battery and in the battery compartment.
