1. INTRODUCTION
Radio madule E-RM 30 scans the data from specially designed water meter, processes them, save to the
memory and transmits data via radio signal. Data sent by radio interface can be read without entering the flat
and even entering the building. E-RM 30 together with electronic heat cost allocators E-ITN 30 protect your
privacy and save your time due to remote data reading.
E-RM 30 rod antenna features a very good efficiency. Deu to this high-quality signla it is possible to read
data without entering the building eve in case of installation in the shaft of multiplestorey building. Data
reading can be made by billing company employee using mobile receiving unit. Data can be also read by
central reading system CRS 40 permanently installed in the building if required. If radio heat cost allocators
E-ITN 30 are also used, data are read simultaneously.
Every user can control current value on analogue dial of water meter. In contrast to the traditional water
meter, radio module E-RM 30 distinguish the direction of water flow – it is thus possible to detect
manipulation with water meter (its turning).
The radio module can be of course secured by conventional mechanical seal against its removal from water
meter. The radio module is equipped with an electronic seal that allows you to identify unauthorized
manipulation and record the e act date. Furthemore, some modelas can detect attemps to manipulate the
water meter by the use of an e ternam magnetic field (e.g. the use of a strong magnet). Information about
such manipulation is transmitted in radio signal.
Month consumptions for forward and back flow for past 12 months can be read from the radio module
memory via infra-red interface.

2. DESCRIPTION
Radio module E-RM 30 is intended for record of data about consumed water – measured by mechanical
water meter – and for remote reading of these data. Mechanical water meter is equipped with rotating
circular disc with reflecting sector. Radio module permanently scan the surface of the disc – its speed and
rirection of rotation. Amount of consumed water is recorded and also direction of flow )forward flow or
backflow).
Radio module E-RM does not dispose of display – is equipped with IR interface with bi-birectional
communication. Via this interface it is possible to set module parameters, switch between operational modes,
get informations about set parameters, module functions and measured values (e.g. chapter 5.2. Reading
data, defining parameters and operating modes a 5.3. Change of operation mode).
Some models of the E-RM 30 (e.g. chapter 2.1. Type list) are able to detect attempts to manipulate the water
meter by using an e ternal magnetic field (for e ample by using a magnet). The actual transfer of data
between the water meter and the radio module is based on an optical principle (just like the radio module
itself) and is therefore not affected by a magnetic field.
The radio module is equipped with electronic seals (and also the option to use mechanical seals) in order to
safeguard the module from tampering. If there is an unauthorised removal of the module from the meter, the
device records and stores the date of the offence and transmits this information by radio signal. The unit
remains in operating mode and after re-activation and re-setting it continues to measure the flow in the water
meter.
2.1. TYPE LIST
Radio modules E-RM 30 are produced in several types, which are divergent in water meter made for,
antenna size and skill of magnetic field detection.
The type with short antenna (about 15mm) is determined to places where is not possible to use a standard
one. Due to the low signal is recommended - if it is possible – to use a module with standard antenna.

3.1.1. Radio module E-RM 30 construction
The E-RM 30 unit consists of a top part with an aperture for infrared communication and a bottom part for
detecting the water meter. Both parts provide a protective covering for the printed circuit boards, electronic
components, antenna and battery. The device is equipped with a 16-bit micro processor with low power
consumption and a radio transmission module, powered by lithium batteries. The bottom part is attached to
the top part by 3 self tapping screws and protected against water ingress by a seal.

4. RADIO MODULE´S OPERATION MODES
Radio module E-RM 30 can be in four operation modes:
•sleeping mode
•automatic activation mode
•working mode
•error mode
Description, how to cange a operation mode find in chapter 5.3. Change of operation mode.
4.1. SLEEPING MODE
Sleeping mode is suitable for prolonged storage prior to radio module use. In this mode device does not scan
position of water meter disc (does not measure amount of consumed water) and does not trasnmit measured
data. Radio module only actualizes real time. Electronic seal is not activated and consumption of electric
power is minimized. The storage period should not e ceed one year.
After installation and sealing the radio module is necessary to do an activationtivaci – description e.g.
chapter 5.3.1. Switch a radio module to the working mode.
Warning!
Witho t an activation, radio mod le E-RM 30 is not reading and sending any data.
4.2. MODE OF AUTOMATIC ACTIVATION
Mode of automatic activation makes installation of water meter with radio module easier. Installation consists
only from putting module on water meter and installation of mechanical seal.
In mode of automatic activation, module regulary tests disc presence. If the presence is detected, measuring
of water consumption is switched on. After 5 liters flows trough, radio module is switched to working mode
and electronic seal is activated. Date of electronic seal activation is saved to radio module memory.
We recommend to do an activation by 5 liters flow immediately after the installation. Otherwise radio module
E-RM 30 is not sending any data and it is not possible to chcek radio modules availability and functionallity
with radio reading unit.
It is also possible to do an activation by chapter 5.3.1. Switch a radio module to the working mode.
4.3. WORKING MODE
Radio module in working mode measures consumption of water, transmits the data in regular intervals,
actualizes real time and test state of electronic seal.
4.4. ERROR MODE
Radio module is switched to error mode when date of billing period beginning is wrong, RAM memory
content is invalid or error occurs when saving data to flash memory. Module does not scan disc position
(does not measure water consumption), does not transmit measured data does not test state od electronic
seal. It only actualizes real time.

5. WORK WITH A RADIO MODULE
5.1. INSTALLATION E-RM 30 TO THE WATER METER
1. Check the condition of the intended water meatier and its housing. If there is any damage or
contamination, clean or replace the meter.
2. Remove the cardboard plugs which are used to protect the E-RM 30 radio module's sensors during
transport. Retain the plugs for covering the sensors during any modes changes (5.3 Change of
operation mode).
3. Attach the radio module to the water meter using the snap-on lock and then seal it. It is
recommended that plastic or adhesive paper seals are used.
4. Activate the radio module depending on the required operating mode.
5.2. READING DATA, DEFINING PARAMETERS AND OPERATING MODES
Given that the radio module RM E-30 is not equipped with a display, it is possible to obtain basic information
about the active mode, the start date of the billing period, and electronic seals using infrared reading unit
IRU 10.00.
The IRU 10.00 displays information related to the last unit it has read. It is therefore necessary to carry out a
data reading from the radio module so that you can view the parameters and operating mode. During the
reading it is necessary to put on the viewing screen so as to avoid interference from ambient light sources.
The front of the meter reading head should be in contact with the plastic cover of the infrared reading diodes
inside the unit (e.g. Illustration 2: Data reading from E-RM 30 with IRU 10.00).
For more information about reading data, display parameters and operating mode, refer to the Installation
and service manual for the IRU 10.00.
5.3. CHANGE OF OPERATION MODE
Using the infrared reading unit, the IRU 10.00, it is possible to change the operating modes of the E-RM30.
In individual operating modes it is only possible to make certain changes (see table below). It is therefore
advisable to first check the current operating mode of the radio module (e.g. chapter 5.2. Reading data,
defining parameters and operating modes) and then change the mode.
