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.

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.

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.
