MULTICAL® 62 • Water meter
5.2.2 Type 67-07: RTC + M-Bus
M-Bus can be connected in star, ring and bus
topology. Depending on M-Bus Master and
cable length/cross section up to 250 meters
with primary addressing can be connected, and
even more using secondary addressing.
Cable resistance in network: < 29 ohm
Cable capacity in network:
< 180 nF
The connection polarity of terminals 24-25 is
unimportant.
Unless otherwise stated in the order, the
primary address consists of the last three digits
of the customer number, it can be changed,
however, via the PC program METERTOOL.
Module to be used in mains supplied meters
only.
5.2.3 Type 67-0B: RTC + pulse output for CV
+ prog. data logger
The RTC and pulse output functions of this
top module are identical with the functions
described for top module 67-08.
The top module is prepared for use in a
Kamstrup radio network together with the Radi-
oRouter base module 67-00-21-000-3xx, read
data being transferred to the system software
via the network unit RF Concentrator.
5.2.4 Type 602-0C: 2 pulse outputs for CE
and CV
This top module has two conigurable pulse
outputs, which are suitable for volume pulses.
The pulse resolution follows the display (deter-
mined by the CCC-code). E.g. CCC=119 (q
p
1,5):
1 pulse/kWh and 1 pulse/0.01 m
3
.
The pulse outputs are optoisolated and with-
stand 30 VDC and 10 mA.
Normally energy (CE) is connected to 16-17 and
volume (CV) to 18-19, but other combinations
can be selected by means of the PC program
METERTOOL, which is also used for selecting
the pulse at either 32 or 100 ms.
