Top module overview
Type 67-02:
energy calculation
This top module calculates the difference between inlet and
outlet energy, whereby an expression of the tapped energy in
open systems is obtained.
Differential energy dE=E4-E5.
Requires CCC
1
= CCC
2
Terminal screws are not used in this module.
Type 67-03: PQ-limiter
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 66-99-003 and a
230/24 V trafo, type 6699-403.
The required power and flow limits are entered into MULTICAL
602 via the PC-program METERTOOL.
Also see instructions: 5512-498
Type 67-05: Data output
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 the optical communication on the meter’s front.
62: DATA (Brown) – 63: REQ (White) – 64: GND (Green). Use
data cable type 6699-106 with 9-pole D-sub or type 6699-098
with USB connector.
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 can be connected with primary addressing,
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.
The module should only be used in mains supplied meters.
Unless otherwise stated in the order, the primary address
consists of the last three digits of the customer number, but it
can be changed via the PC program METERTOOL.
In order to function correctly in a MC602, minimum program
version D1, released in March 2011, is required.
