9.10 Top modules
Type 67-01: RTC (Real Time Clock)
The top module consists of real time clock and
battery backup.
When the MULTICAL® 601 calculator top is placed
in the connecting bracket and is powered, current
date and time is transferred from the top module to
the calculator.
The top module is recommended for applications in
which correct date/time in data loggers as well as in
time-controlled tariff is considered important.
Real time clock and battery backup are standard
features in all other top modules.
Terminal screws are not used in this module.
Type 67-02: RTC + D energy calculation and time
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.
The module also comprises a time data logger.
Terminal screws are not used in this module
Type 67-03: RTC + 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 trafo,
type 66-99-403.
The required power and flow limits are entered into
MULTICAL® 601 via the PC-program METERTOOL.
Also see instructions: 5512-498.
The module also includes an hourly data logger.
Type 67-05: RTC + 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 the 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 also includes an hourly data logger.
Only current and accumulated data can be read.
Data loggers for time/days/months/years cannot
be read through the data port of top module 67-05.
