Power Supply

All input modules (data loggers) have the following three power supply variants of the following power supplies):

•Two 3.6 V lithium thionyl chloride AA batteries. The power supply of the batteries suffices to carry out measurements and store data.

oRunning on battery only, the back light will be switched off and the device will show "Device Timeout" on the display.

oThe display will then switch off and after 1 or 2 measurement intervals will switch back on.

oThe display back light can be switched on by pushing on the button and waiting for the next measurement interval.

•24 VDC ±10 % / <100 mA1 via terminals (V+ / V-)

•Power over Ethernet (PoE), per standard IEEE 802.3af, Class 1

 

IMPORTANT: Devices with an Ethernet interface require PoE or 24 VDC!

 

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.

Digital interface

The logger is operated completely via the LAN or wireless interface.

Lan

If the device is in timeout (Lan cable not pluged in), the alarm limits are stored on the device and in the case of excursions, the display will turn red (if battery only, then no backlight) and will beep (if so configured).

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:

•Logging of the measured values of the connected probe,

•Data logging of up to 44,000 pairs of measured values,

•Transfer of the recorded data to the RMS software,

•Calibration and adjustment of the probe,

•Firmware update...

 

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.

RTCC (Real Time Clock Calendar)

The device is equipped with a real time clock. The time is continuously synchronized if there is a connection to the server.

 

 

Data Logging and Measurement Interval

For each temperature measurement, the measured values are stored in the memory with the associated time stamp. At a measuring interval of one minute, data can be stored for one month, which corresponds to approx. 44,000 measurements. If the memory is full, the oldest values are overwritten.

 

 

Indicator and Button

The device has a button and multicolored LED for use and indication of the operating state. The button is used to start the device or switch it off in battery mode. The LED indicates the device status and whether it was possible in the current measurement interval to carry out a valid measurement and send the data to the monitoring system.

 

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.

After removing the wall bracket, insert the batteries according to the label in the battery compartment.

oThe batteries are used to power the unit in the event of a failure of the external power supply. In battery operation, the functionality is limited and the device cannot be addressed via Ethernet.

oLithium AA batteries with 3.6 V are used.

oThe mounting position must be observed. The polarity is indicated on the battery and in the battery compartment.

 

Rotronic have tested and recommend the following batteries:

1.Fanso ER14505M,

2.Titus ER14505M,

3.Ramway ER14505M.

 

When using other batteries, Rotronic cannot guaranty that the logger will work correctly.

 

Differences between PoE and Battery:

 

On PoE:                                                                   On Battery:

Warning/alarm/error = backlit red display                  Warning/alarm/error = display is not red and not backlit
