1PRODUCT DESCRIPTION
1.1 BRIEF DESCRIPTION
IZAR RC 868 i W G4 is a unidirectional radio transmitter that collects the data coming from a Diehl
Metering water meter and transmits in real time the index and other operating information every 12
seconds in R3 mode and every 15 minutes in long-range fixed network R4 mode.
There is also an "extended historical values" mode in which 31 daily historical values or 29 hourly
historical values are available. In this mode the information is sent every 30 seconds in R3 mode and
every 15 minutes in R4 fixed wide area network mode.
Mobile reading in walk-by / drive-by / passive drive-by:
The data sent by IZAR RC 868 i W G4 is collected using either a handheld computer or tablet
equipped with an IZAR RECEIVER BT in walk-by or drive-by mode or with an IZAR RDC VEHICLE in
passive drive-by mode. Data is then transferred directly to a centralized monitoring system.
Fixed network:
A fixed receiver IZAR RDC STANDARD/IZAR RDC BATTERY (fixed network R3) or IZAR RDC
PREMIUM (long-range fixed network R4) installed in a fixed location will collect the data and send it
at predefined intervals, via GPRS or LAN, to a centralized server. Reading through M-Bus application
with an IZAR CENTER associated to an IZAR RECEIVER M-BUS and IZAR@NET 2 software is also
possible.
Logger functions:
IZAR RC 868 i W G4 has an integrated data logger that registers consumption at regular intervals. In
case of consumer dispute or for analysis purposes, the data is available via the IrDA interface of the
module and is transferred to the handheld or computer/tablet via a dedicated application. The
consumption backup interval is programmable between 1 to 40 minutes. This interval can be
modified thanks to the same dedicated application.
1.2 COMPATIBILITY WITH DIEHL METERING METERS
fig.1
IZAR RC 868 i W G4 is
compatible with all the water
meters of the Diehl Metering
modular range equipped with
a grey or red ring and marked

1.3 CONFIGURING IZAR RC 868 I W G4
IZAR RC 868 i W G4 is configured with an IZAR OH RS232 or
IZAR OH BT optical head.
The optical head must be positioned in front of the diode on the
top of the radio and resting on the boss (fig.2).
Data required during configuration:
•Meter serial number
•Pulse weight (unit/value)
•Index (unit/value)
•Profile
The choice of mode (normal or extended historical values) is
made during factory or on-site configuration.
The software recognizes automatically the module type. For
more details on the configuration and the “logger” function,
refer to the software user guide. fig.2
2OPERATION
2.1 OPERATING PRINCIPLE
2.1.1 COMMUNICATION
IZAR RC 868 i W G4 sends data in R3 mode using the OMS standard version 3: OMS is a
communication protocol developed within the framework of the CEN TC 294 recommendations of the
EN 13757-3/-4 standard regarding the use of the 868 MHz frequency band for radio reading of
metering devices.
2.1.2 OPERATION
IZAR RC 868 i W G4 radio module contains an electronic circuit that collects information coming
from a Diehl Metering water meter (current index, 11 historical index values, detailed leaks
information and alarms).
In “normal” mode, information is emitted:
•Every 12 seconds with the OMS protocol at the 868.95 MHz frequency in R3 mode for the index
and alarms. Detailed information regarding leaks and historic of consumptions are transmitted
every 6 sendings.
•Every 15 minutes at the 868.30 MHz frequency in R4 long range fixed network mode.
In “extended historical values” mode, information is emitted:
•Every 30 seconds in R3 mode at the 868.95 MHz frequency
•Every 15 minutes at the 868.30 MHz frequency in R4 long range fixed network mode
Important notes regarding the “extended historical values” mode:
•In this “extended historical values” mode, detailed leakage information is not sent
•In this mode, the current index is not sent. Only historical values are present in the frame. The
most recent index sent in the frame is the one from the previous day at 23:59.
•Since no current index is sent, this mode is not OMS certified, despite the fact that the data in
the frame is OMS compatible.
•In this mode it is recommended not to activate the reception of the very long frame in the
IZAR@MOBILE 2 software for mobile tours because this frame is not sent.

2.1.3 INTEGRATION OF BACKFLOW
IZAR RC 868 i W G4 has a flow direction detection feature and a special algorithm enabling it to take
into account a backflow situation. The index transmitted by IZAR RC 868 i W G4 is a “real time”
index -> backflows are registered immediately.

Current index* Real time index transmitted by the radio.
11 historical index values* Indexes recorded on specific dates.
Either daily, weekly, monthly
(i.e. the first of each month) or yearly (i.e. 1st day of each year).
Detailed leaks information*
The following detailed information is provided:
•Number of leaks
•Date of the last leak
•Leak duration in days

2.3.2 ALARMS DETAILS
Leak detection Alarm triggered:
- if there is a continuous consumption over a programmable period
of time, usually several days.
Low battery
The alarm is set when the remaining lifetime of the battery is lower
than 1 year.
The typical lifetime is up to 15 years when the
temperatures are distributed evenly within the ranges given below:
Temperature range
%
-15°C to +5°C
10% of the time
+5°C to +30°C
80% of the time
+30°C to +55°C
10% of the time
NB: an extended use at high temperatures will cause a loss of
battery autonomy. If, for example, the module is permanently at
+55 °C, the life expectancy of the radio will be reduced to 10 years.
Meter stopped or blocked Alarm triggered: - if no consumption has been recorded over a programmable period
of time, usually several weeks.
Meter sizing :
under calibrated
Detection of undersized meter compared to the need, leading to a
meter overflow.
Alarm triggered:
- if a Q1 programmable flowrate is exceeded during a D1
programmable duration.
Meter sizing :
over calibrated
Detection of oversized meter compared to the need, leading to a
meter underflow.
Alarm triggered:
- if a Q2 programmable flowrate is never reached during a D2
programmable period.
Radio disconnected Alarm triggered:
- if the radio is disconnected from its meter.
Backflow Alarm triggered :
- if a backflow is greater than a programmable value, usually a few
tens of litres.
Alarm reset:
alarms are reset automatically after a programmable period. This period must be
compatible with the frequency of reading.
Any radio module delivered already clipped on a meter has a predefined profile. Any
modification may affect the operation of the product. Diehl Metering shall not be held
liable for any malfunctioning of the product following a modification of configuration.

3INSTALLATION PRECAUTIONS
3.1 IDENTIFICATION
Make sure that IZAR RC 868 i W G4 is compatible with the meter on which it is clipped (marked “Ti”
or “Ha + Ti”).
3.2 INSTALLATION
If there is a cover on the meter, take it off by pushing out the hinge pin (fig.4). If the cover does not
have a metal hinge, remove it by hand.
fig.4
Carefully clean the top of the register to remove any traces of soiling.
Position the IZAR RC 868 i W G4 by aligning the hinges up with each other (fig.5).
Press the ring onto the module with your hand only, until it clicks into place. Do not use a mallet or
hammer. This is an electronic component to be handled with care.

3.3 SECURING SYSTEM
A screw tightens and loosens the ring on the meter (fig.6). This system secures the assembly and
ensures pullout resistance. In open position, it is possible to remove the ring without damaging the
hooks.
Put the sealing label (delivered with the radio module) on the locking screw.

4MAINTENANCE
Maintenance IZAR RC 868 i W G4 requires no specific maintenance.
Do not clean it with solvents or abrasive cleaners, as these would damage
the plastic shell. If necessary, use a damp cloth or sponge.
Storage
The product may be stored in a dry place at temperatures between -20°C
and +70°C.
Prolonged storage at high temperatures may cause a significant loss of
autonomy.
