MULTICAL® 603
140 Kamstrup A/S ∙ Technical description ∙ 5512 ‐ 2029_A1_GB_06.2017
11.3.4 M ‐ Bus + pulse outputs (type no.: HC ‐ 003 ‐ 21)
The M ‐ Bus module is powered through the M ‐ Bus network and is thus independent of the meter’s internal supply.
Two ‐ way communication between M ‐ Bus and energy meter takes place via a digital isolator providing galvanic
separation between M ‐ Bus and meter.
The module supports both primary, secondary and enhanced secondary addressing. The module can communicate at
communication speeds of 300, 2400, 9600 or 19200 baud and automatically detects the speed used.
The output data package can be configured to include various register combinations by means of the PC ‐ programs
METERTOOL HCW and READy Manager.
The module is fitted with two sets of screw terminals for connection to the M ‐ Bus network. The M ‐ Bus cable can thus
be looped through the meter so that the use of junction boxes can be avoided. The connection is independent of
polarity. The M ‐ Bus cable must be copper twisted pair. Max cable size is 1.5 mm

11.3.5 M ‐ Bus + Thermal Disconnect (type no. HC ‐ 003 ‐ 22)
This M ‐ Bus module has an output for connection of a 24 VAC, normally open or normally closed, thermal actuator,
which is supplied by the module’s external power connection. Thermal Disconnect enables remote disconnect of the
flow, e.g. in connection with energy management and maintenance or as a result of leakage detection. The Thermal
Disconnect system is physically placed on the M ‐ Bus module, but the output is controlled by MULTICAL® by means of
commands that are sent via the M ‐ Bus network. The module is power ‐ supplied by the 24 VAC or 230 VAC power supply
in MULTICAL®. It is not possible to battery ‐ supply MULTICAL®.
The Thermal Disconnect module requires an external 24 VAC power supply for operating the thermal actuator.
Transformer type no. 6699 ‐ 403 can supply both a 24 VAC ‐ supplied MULTICAL® and a thermal actuator with a power
consumption of up to 5 W.
For controlling Thermal Disconnect remotely, the Windows® ‐ based PC program USB Meter Reader is used.
