The radio module is used for wireless reading of MULTICAL
®
41.
When connecting the supply voltage the radio module retrieves the type and meter number of the meter and
transfers data to the memory of the module.
The radio module is ready to communicate in less than 10 seconds.
As standard the radio module is supplied with an internal antenna.
The radio module is read via the hand-held terminal, but is prepared to form part of a radio network.
The radio system is designed to meet the requirements of the EN 300 220 and EN 301 489 standards as well as in
the R&TTE directive (

quipment).
For further information, see Technical Description 5512-012.
The radio module also offers the option of leak surveillance. Every hour the meter’s volume is checked and
compared to an alarm limit.
If the limit is exceeded, the radio module sends an alarm to a radio network which handles the leak alarm.
The alarm limit is factory preset to 10 litres.
Furthermore, the module is mounted with a pulse output. The pulse output, which emits one pulse per 10 litres, is
intended for CTS-systems.
Power: 30 V
Load: 10 mA
Pulse duration: 0.1 seconds
The pulse output is not active when delivered from Kamstrup.
The jumper J4 must be removed in order to activate the pulse output.
