Scope:

This manual is valid for the RMS data logger from firmware version V1.x. The low-order digit of the manual is
updated with each new release.

1 Overview

1.1 RMS System Overview

The Rotronic Monitoring System (RMS) is a network comprising various devices and the RMS server software.
The software is the heart of the system. It collects all measured data of the devices and saves it in the database.
The individual devices work as input modules (data loggers) and as output modules (displays, analog outputs,
switched outputs). The user can view the system data at any time on a PC, laptop or smart phone.

1.2 Device Overview

All devices can be configured as wanted as modules of the system. The following table shows all basic types of
the RMS devices. Almost all modules1 have the following options:

 Interface: Ethernet / Wireless
 Housing: Wall housing / DIN top hat rail housing

Display Module

The display module can show any values from the
RMS network. Humidity, temperature and switch
states can be configured per software.

Standard Logger

Records the measured data of the digital HygroClip
HCD or other RMS probes. Stored in the ring
memory, the data are then sent to the server
software.

Output Module

Provides two analog voltage or current outputs or is
also available as variant with two solid-state relays in
order, for example, to switch alarm lamps.

Input Module

Records voltage or current signals from analog
devices such as particle counters, flow transmitters
or CO2 probes. For example:

 HF5 transmitter (humidity & temperature)
 AF1 transmitter (air flow)
 CO2 transmitter (CO2)
 PF4 transmitter (differential pressure)

Temperature Logger

The loggers can be equipped with various
temperature sensors (NTC, Pt100, Pt1000 or K­element). This offers highest flexibility in use.

Mini Logger

A temperature logger with integrated or remote NTC
sensor. Instead of a temperature sensor, it is also
available with a switch input in order, for example, to
monitor door contacts.

Gateway

The gateway is the connecting element between
Ethernet and wireless network and forwards the data
flow from the loggers to the data centre.

1.3 RMS Data Logger

Order code: RMS-LOG-L or RMS-LOG-868 or RMS-LOG-915
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:

o Logging of the measured values of the connected probe
o Data logging of up to 44,000 pairs of measured values
o Transfer of the recorded data to the RMS software
o Calibration and adjustment of the probe
o Firmware update

1.4 RMS Display

Order code: RMS-D-L
The RMS Display is a freely configurable device. The unit can be placed anywhere, not necessarily next to the
measurement point. The display allows the visualisation of measurement values, conditions and alarms of
devices within the RMS software.

The RMS Display provides the following basic functions:

o Display of up to 4 measuring values and their trends
o Actualisation every 10s
o Display of errors, alarms, warnings and notifications
o Display of the time

The RMS display will show 2 measurement values at a time. Should more than 2 measurement values be
selected, then the display will automatically switch every 5 seconds between the measurement values.

Under each measurement value, the name of the measuring point will be indicated. The parameter will be
shown on the right, next to the measurement value

Various notifications can also be displayed:

o Error: E
o Alarm: A
o Warning: W
o Reminder: R

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 mA2 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.

1.7 RTCC (Real Time Clock Calendar)

The device has a real time clock calendar. The time is synchronized continuously when connected to the server.

1.8 Data Logging and Measurement Interval

The values of every measurement are saved in the memory with the time stamp. At a measurement interval of
one minute, it is possible to save data of one month, which corresponds to 44,000 pairs of measured values.
When the ring memory is full, the oldest values are overwritten.

1.9 Indicator and Button

The device has a button and multicolour 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.
