3.5.3 Mains unit
The mains unit indicates to the calculator if mains voltage is present. If the mains unit fails, the backup battery (CR2032) in the mains unit provides the power supply for up to 1 year. This back-up battery
can be replaced if necessary. The LCD readings (on pressing button) and the date and time are still
updated, but none of the measuring functions work, incl. the flow rate measurement. Communication
still functions over the optional M-Bus, RS485 and RS232 modules or the optical interface, but this
reduces the life of the back-up battery. The integrated radio function is switched off in the event of
mains failure.
3.6 Calculator interfaces
The calculator is equipped as standard with a ZVEI optical interface. This is located on the calculator
below the display (Fig. D). This interface can be used for communication with the calculator (using the
IZAR@Mobile2 software) and for checking it.
Communication uses the M-Bus protocol, for which the Bluetooth IZAR OH BT opto head is suitable.

extra-low voltage (SELV) type and comply with EN 60950-1.
3.6.1 Communication modules
The calculator supports two communication channels over the same or different interfaces. If the
calculator has an integrated radio, it is possible to use additional the two slots for modules.
The protocol is different for each of the two channels and is preset ex works, but can be set to
customer-specific requirements using the IZAR@Mobile2 software. Each module has its own primary
address. Both modules have one secondary address, which is set to the serial number ex works. The
calculator is equipped with automatic baud rate detection.
M-Bus module
The M-Bus communication module is a serial interface for communication with external devices (MBus control centre), e.g. IZAR CENTER. A number of devices can be connected to a control centre.
Only one M-Bus load is needed. The M-Bus module is electrically isolated.
Seite 13 von

6.1.4. Installing the temperature sensor
NOTE
The temperature sensors are to be installed symmetrically in the forward and return
line and preferably direct. The free temperature sensor can be installed in a ball
valve or in a pocket conforming to the requirements for this type of sensor. The
forward and return sensors must be inserted as far as the bottom of the pocket and
then fixed in position. For installation in a ball valve, a 5-piece coupling set is
enclosed with the meter in a separate bag. Bores in the flow sensor can be used for
symmetrical installation of the temperature sensors. In Germany, sensors up to
nominal pipe diameters of 25 mm are to be installed directly immersed.
If the temperature sensors are connected permanently, the cables must not be
shortened or lengthened. If replaceable conformity-marked temperature sensors are
used, the connecting cables must have the same length for the forward and return
line and not exceed 10 m; the cross-sections of the cables must comply with
EN 1434-2. They are connected to the marked Pt 100 or Pt 500 terminals in line with
the electrical compatibility of the integrator and finally sealed. The connecting cables
of the temperature sensors must be as short as possible. These cables are not to be
laid together with mains supply cables in cable ducts or cable racks. The minimum
separation of 50 mm for low-voltage cables must be maintained in accordance with
EN 1434-6.

12. Error analysis
The calculator continuously monitors its own operation and displays various error messages. The error
code is displayed in the main loop if an error occurs. The permanent display shown corresponds to the
“normal” display (e.g. a temperature sensor error is not shown in the flow rate display). In the basic
display mode, the display changes between error codes and the basic display (exception: error display
“C - 1” is shown permanently). All the other windows can still be selected by pressing the button.
The error display disappears automatically as soon as the cause of the error has been cleared. All
errors present longer than 6 minutes are saved in the error log.
The following table shows the error codes indicated in the display with their respective meaning:
Error display Meaning
C – 1 Basic parameter error in flash or RAM
E – 1
Temperature measurement error
- Temperature range exceeded [-9.9 °C … 190 °C]
- Sensor short-circuit
- Sensor break
E - 3** Temperature sensors reversed in hot and cold lines
E – 5
Reading too frequently
- M-Bus communication not possible for short time
E – 8
