INTRODUCTION
The M-Bus Splitter allows two parties to have access to the same main
meter. Two M-Bus masters can be connected to the meter and register
readings individually.This manual provides the information needed to
get started with the M-Bus Splitter. For a complete description of the
product or for information in Swedish, visit the Elvaco AB website,
www.elvaco.com.
OVERVIEW
M-Bus Splitter
Share up to 4 M-Bus slaves
1. Screw terminal M-Bus OUT1 - Isolated
2. LED M-Bus OUT1 - Isolated
3. LED M-Bus IN
4. Screw terminal M-Bus IN
5. Configuration jumpers
6. Screw terminal external power (optional)
7. LED M-Bus OUT2 - Power
8. Screw terminal M-Bus OUT2 - Power
MOUNTING
M-Bus Splitter can be mounted on a DIN-rail or directly on the wall. For
wall mounting, the black mounting bracket on the back of the M-Bus
Splitter has to be demounted from the unit and mounted on the wall.
The M-Bus Splitter will then be snapped on to the black mounting
bracket.
1. 24 V power supply should be connected when more than one
meter is connected or if the Splitter does not manage to operate
the connected meter. It is important that the power supply is only
used to power the M-Bus Splitter (and not additional devices).
2. Connect meter on the terminal marked with M-Bus IN. The meters
must have unique primary addresses between 1 and 250.
3. Connect M-Bus master on the terminals marked with M-Bus OUT2
and OUT1. M-Bus OUT2 must be connected as it provides power
to the Splitter.
M-BUS 2-WIRE BUS
M-Bus is a multi-drop 2-wire bus with no polarity. Use a cable of area
0.25-1.5 mm2, e.g. a standard telephone cable (EKKX 2x2x0.5).
OPERATION
When the Splitter is powered up it takes up to 5 minutes before it is
ready to use since it needs charging. During charging, all LEDs will flash
four short flashes in order every three seconds.
1. There are four settings to be done to adapt the Splitter to the
installation. This is done by setting the jumpers in on or off mode.
See Settings for more information.
2. Start the meter installation by changing the position of any jumper
(off to on/on to off). Put the jumper back to its original position.
See settings.
3. During scanning, the LED for M-Bus IN flashes with a short flash
every second. Depending on the scanning speed the scanning
time varies from 1 to 8 minutes.
4. When the scanning is completed, the M-Bus Splitter is in normal
operation. See LED indications.
TROUBLESHOOTING
Make sure that:
1. All cables are connected properly, both on the M-Bus Splitter and
on the M-Bus master.
2. The voltage on M-Bus IN is greater than 23 VDC. If the voltage is
lower, disconnect one meter at a time to find the failing meter.
3. The voltage on M-Bus OUT2 is greater than 26 VDC. If the voltage
is not within this range, check the function of the M-Bus master.
Connect external 24 VAC power supply when connecting more
than one meter. When low voltage is detected on M-Bus IN, all
LEDs flashes four times.
4. The connected M-Bus meters all have unique primary addresses.
5. Contact the supplier if the error remains.
