General information on the guide

The guide is intended for trained specialized personnel. For this reason no basic working steps are included.

Package content

Please check the package content before you install or use the IZAR RECEIVER M-Bus for the first time.

• IZAR RECEIVER M-Bus
• Wall bracket
• 2 fastening screws

Description

The IZAR RECEIVER M-Bus receives radio telegrams from the IZAR RADIO modules or Diehl Metering meters with integrated radio and saves them in the internal memory. Each time a new telegram is received, the IZAR RECEIVER M-Bus overwrites the old telegram of this meter.
The IZAR RECEIVER M-Bus can only be used in combina-tion with a IZAR CENTER M-Bus Master.
An automatic, interval-controlled reading is possible as with a normal M-Bus meter.
The data saved in the IZAR CENTER can then be transmit-ted to the IZAR@NET software.

Instructions

The IZAR RECEIVER M-Bus should be mounted and put into operation by qualified experts only.

When installing suitable preventive measures for EMC protection must be met.
Please ensure that the M-Bus voltage – depend-ing on the cable length (resistance and impedance) is never below 32 V, in order to operate the IZAR RECEIVER M-Bus.

The IZAR RECEIVER M-Bus requires around the same amount of M-Bus current as 20 normal M-Bus terminal equipment.

The IZAR RECEIVER M-Bus can not be operated with HYDRO-CENTER 25 devices.

The maximum cable length is limited to 100 m … 1 km depending on the number of connected IZAR RECEIVER M-Bus and other M-Bus devices.

Please ensure for the initial operation of the IZAR RECEIVER M-Bus that the most recent version of the Diehl Metering IZAR@CENTER soft-ware is used.
