3.4 Functional description
The calculator is a fully electronic measuring instrument. It is equipped with a data memory that
enables comparison of the previous months’ readings with the current readings. The data measured
by the calculator are shown in the display. The display is provided with various windows as loop
functions that can be called up in succession to display the system information assigned to each
window (e.g. energy amounts, water amounts, current temperatures, maximum values).
The calculator has 6 display loops: main loop, accounting date loop, info loop, pulse input loop, tariff
loop and monthly value loop. The individual loops are described in Section 8 “Operation”. Some
windows in a loop and whole display loops can be deactivated separately to make the window
structure clearer.
Various display windows comprise up to seven displays that change at intervals of 2 –4 s.
The loops in the display are numbered from 1 to 6 to help the user find his way around quickly.
The main loop is programmed with the current data as default setting, e.g. for energy, volume, flow
rate and other parameters. It is not possible to change the order of the available data.

3.5 Power supply
Possible power supplies:
A cell, 3.6 V DC lithium battery, with a lifetime of 11 years (standard version, with radio)
D cell, 3.6 V DC lithium battery, with a lifetime of 20 years
Mains unit 24 V AC
Mains unit 230 V AC
Fig. C Power supplies
1 A or D cell, 3.6 V DC lithium battery
2 Mains unit 24 V AC / 230 V AC
The various power supplies can be changed in the field.
NOTE
The calculator switches automatically to power save mode if the button is not
pressed for approx. 4 minutes. The display is also switched off in this case, but can
be switched on again by pressing the button. Communication is maintained, e.g.
over the M-Bus or the optical interface. The calculator does not switch to power save
mode if an error exists. The error is shown in the display as an error code.
Never connect between two phases if a mains unit is used, as this would destroy the
mains unit. The protective safety cover must be installed at all times. The cable is to
be fused at max. 6 A and protected against manipulation.
Used batteries must be disposed of at suitable collection points.

3.5.1 Battery
A 3.6 V DC lithium battery is fitted in the standard version. The battery is not to be charged or short-
circuited. Ambient temperatures below 40 °C extend the life of the battery.
DANGER
There is a risk of explosion if the battery is replaced with the wrong type of
battery.
3.5.2 Overview of the measuring rates
The following table shows the lifetime of the batteries depending on the standard measuring rates.
Customer versions can differ from the standard measuring rates in the measuring rate and battery
lifetime.

3.5.3 Mains unit
The mains unit indicates to the calculator if mains voltage is present. If the mains unit fails, the back-
up 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@SET software) and for checking it.
Communication uses the M-Bus protocol, for which the Bluetooth IZAR OH BT opto head is suitable.

3 Fixing lugs
NOTE
Inserting a module into slot 2 immediately disables the internal radio function.
NOTE
If other external devices are connected to the calculator, these must be of the safety
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. An
additional communication module can be used in radio operation.
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@SET software. Each channel has its own primary
address, but only one secondary address exists, which is set to the serial number ex works. The
calculator is equipped with automatic baud rate detection. Default baud rate is 2400 baud.

M-Bus module
The M-Bus communication module is a serial interface for communication with external devices (M-
Bus repeater), e.g. IZAR CENTER. A number of devices can be connected to a control centre. The M-
Bus module is electrically isolated.
Communication over radio
The integrated radio function is an interface for communication of predefined protocols with
Hydrometer radio receivers. The communication protocol is preset, but can be defined to a customer-
specific protocol using the IZAR@SET software. By default, the internal radio is disabled. When the
calculator receives in total 10 pulses for the first time on the volume pulse input, the integrated radio is
enabled.
RS-232 module
The RS-232 communication module is a serial interface for communication with external devices, e.g.
a PC. The transmission speed is 300 or 2400 bauds. A special data cable is required for connecting
this module to the PC. (Order no.: 087H0121). The RS-232 module isn’t electrically isolated.
RS-485 module
The RS-485 communication module is a serial interface for communication with external devices, e.g.
a PC. It can only communicate at a transmission speed of 2400 bauds. The RS-485 module is
electrically isolated.
L-Bus module
The L-Bus communication module is a serial interface for communication with an external radio
module, in which the M-Bus protocol is transmitted. It can be used for example if the radio range of the
internal radio is not enough. The L-Bus module isn’t electrically isolated.
3.6.2 Function modules
Pulse output module
This module contains connections for two pulse outputs, which can be programmed as desired using
the IZAR@SET software. The energy pulse output is marked as standard as “01 - ┴” on the module
and “Out1” in the display. The volume pulse output is marked as “02 - ┴” on the module and “Out2” in
the display. The both pulse outputs are electrically isolated.
Pulse input module
This module has 2 pulse inputs for connecting 2 additional pulse meters, such as water meters, gas
meters or electricity meters. The possibility of programming the pulse value using the IZAR@SET
software enables volume or energy values to be displayed and transmitted remotely over a suitable
communication module. Initial meter counts can also be parametrized for these two pulse inputs. The
pulse input module isn’t electrically isolated.
Combined module
The combined module is equipped with two pulse inputs and a pulse output, which can be
programmed as desired using the IZAR@SET software. Pulse input 1 is marked “I1 - ┴” on the module
and “IN1” in the display, pulse input 2 “I2 - ┴” on the module and “IN2” in the display. The pulse output
is marked “01 - ┴” on the module and “Out1” in the display. The pulse output on this module isn’t
electrically isolated.

Analogue module
The analogue module has the size of 2 standard modules and has two passive outputs with 4 to 20
mA. If one analogue module is mounted in the meter, no other module can be installed. The internal
radio is still working. The connection cable between the main pcb board and the module has to be
installed on port 1 (left slot). By default, the two analog outputs are not programmed, the values can
be programmed with the help of the software IZAR@SET (standard). The analogue module is
electrically isolated.
