Type 67-02:
D
Energy calculation and hourly data
logger
This top module calculates the difference between
forward and return energy, whereby an expression
of the tapped energy in open systems is obtained.
Differential energy dE=E4-E5.
The module also includes an hourly data logger.
The connection terminals of this module are not
used.
Type 67-03: PQ-l hourly data logger
The module has two pulse outputs which can be
used for UP/DOWN control of a low-speed three-
point motor-operated valve via an external solid-
state relay, type S75-90-006 and a 230/24 V trans-
former, type 66-99-403. The required power and
flow limits are entered into MULTICAL
®
602 by
means of the PC-program METERTOOL.
Also see instructions: 5512 -497.
The module includes an hourly data logger too.
Type 67-05: Data hourly data logger
The module has a galvanically separated data port
which functions together with the KMP protocol.
The data output can be used for e.g. connection of
external communication units or other hardwired
data communication which it is not expedient to
carry out via optical communication on the meter’s
front.
62: DATA (brown)–63:REQ (white)–64: GND (green).
Use data cable type 66-99-106 with 9-pole D-sub or
type 66-99-098 with USB connector.
The module includes an hourly data logger.
Only current and accumulated data can be read.
Hourly/daily/monthly/yearly data loggers cannot
be read through the data port of top module 67-05.
Type 67-07: 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 pri-
mary addressing can be connected, and even more
using secondary addressing.
Cable resistance in network:
<
29 Ohm
Cable capacity of network:
<
180 nF
The connection polarity of terminals 24-25 is un-
important.
Usually the primary address is identical with the
last digits of the customer number (000-250).
However, it can be changed by means of the PC
program, METERTOOL.
