5 Technical data

• Temperature range
Storage: -20 °C to +65 °C
Operation: -10 °C to +65 °C
• Cable length: 1.5 m
• Hermetically sealed housing IP 68
• EMC acc. EEC directive 98/34 equal European
standards EN61000-6-1
6 Pulse-outputs (I1/I2) all types
Open drain transistor switch according ISO/TC30
Vmax: 24V DC / Imax: 20mA / Pmax: 0,48VA / fmax:
5Hz
Max. voltage by closed switch: 0.3V + I * 260 Ω
If the data interface isn't used the serial resistance
can be reduced by 150 Ω with the connection of
green and brown wire.

HRI-B: Pulse length 124 ms fixed, Flow direction
(A3/B3) signal l2 is 18μs prior to I1
Operational cable length up to 10 m
Transient voltage protection is highly recommended
for wiring outside buildings.
7 Data interface (HRI-Bx only)
M-Bus and MiniBus (Auto speed detection:
300/2400 Baud)
Protocol according EN13757-3 equal IEC 870 / EN
1434-3
Data: meter ID, meter index (optional 1 litre or 1 m3
resolution)
Operational cable length: according to M-Bus speci-
fication.
PLC
With M-Bus reading is unlimited, with MiniBus the
reading shouldn't be more than 5 times per day to
avoid a battery lifetime of less than 10 years.
With the data interface the following values can
be set via MiniCom (version >3.0); standard setting
+24V
from the factory in brackets:
• Primary address (0)
• Secondary address (HRI-Fabrication No.)
• Meter ID No. (HRI-Fabrication No.)
0V
• Meter index (0); if the aluminium foil is missing,
index can be different
• Pulse mode (according the order)
0V
• Pulse weight (according the order)
Attention: The resolution of meter index can't be
changed, so this setting must be correctly defined
with the order.
If the HRI is ordered mounted on top of a meter, the
secondary address, meter ID no. and meter index
are preset with the meter's values. Setting on site
isn't necessary.
If data interface and pulse output is used at the
same time, potential free connection for the connect-
ed devices are requested. During data communica-
tion pulse lost is possible depending on the pulse
collector's input circuit.
