Elvaco CMe3100 Installation guide

INTRODUCTION
CMe3100 is an intelligent TCP/IP M-Bus master with logging
functionality that can read and interpret meter data from all M-Bus
meters. CMe3100 can also read and organize networks with Elvaco’s
wireless M-Bus receiver via M-Bus and TCP/IP. It is ready to use with all
ABB DIN-mounted electricity meters and any M-Bus meter following
the M-Bus standard protocol. Meter data can be downloaded or sent
through a variety of formats and protocols, such as FTP, e-mail, Modbus,
M-Bus slave port, M-Bus over TCP/IP and REST-protocol. For a complete
description of the product or for information in Swedish, visit the Elvaco
AB website, www.elvaco.com.

MOUNTING
The CMe3100 should be mounted in a DIN-rail enclosure on a DIN-rail.
The metallic clip on the bottom is used to mount and demount the unit
from the DIN-rail. For safety reasons, a DIN-rail enclosure must cover
the terminals.
POWER SUPPLY
The installation should be performed by a qualified electrician or an
installer with the required knowledge. The power supply must be
protected with a 10 A circuit breaker of characteristic C or slow blow
fuse. The power supply should be connected via a clearly marked, easily
accessible and nearby switch so the unit can be switched off during
service work. Main supply should be connected to screw terminal (1)
and (2). Main supply voltage should be in the range of 100-240 VAC,
50/60 Hz.
M-BUS MASTER
M-Bus is a multi-drop 2-wire bus with no polarity. CMe3100 is
equipped with an M-Bus master for 32 slaves (32 M-Bus loads , 48
mA). Overloading the bus will turn the ERR LED (4 ) on and turn off
the M-Bus bus. If you wish to connect more slaves, mount an M-Bus
extender from the CMeX Series on the right side of the CMe3100
to expand the capacity. The master can communicate with 300 and
2400 baud. All connected M-Bus slaves must have unique primary or
secondary M-Bus addresses depending on addressing mode. Use a
cable of area 0.25-1.5 mm2, e.g. a standard telephone cable (EKKX
2x2x0.5). Connect the wiring to the connector (13). Do not exceed the
maximum cable length of 1000 m.
WIRELESS M-BUS
CMe3100 supports reading of wireless meters via Elvaco’s wireless
M-Bus receiver. The M-Bus receivers can be connected to the local
M-Bus master on CMe3100 or via CMe3000 over TCP/IP.
Elvaco’s wireless M-Bus system is automatically configured and
wireless meters can be read directly.
M-BUS SLAVE PORTS
CMe3100 is equipped with two M-Bus slave ports used for sharing
meter data to other M-Bus systems. The ports can be configured
individually in the web interface. Connect the cables from the other
system’s M-Bus master to the terminal marked ”M-Bus slave 1” (11) or
”M-Bus slave 2” (12).
ETHERNET CONNECTION
Connect the TP cable of type Cat 5e or better to the RJ45 connection
(9). On successful connection to the switch/hub, the yellow LAN
LED (6) will be permanently on or flashing. If CMe3100 has or will be
assigned an IP address, the red ERR LED will flash 50/50.
IR INTERFACE
The IR interface can be used beside an ABB electricity meter or CMeX
module. Remove the IR shield (14) and mount CMe3100 on the left
side of the meter or CMeX module and leave no space between the
products. Do not remove the shield unless the IR interface is used.
GETTING STARTED VIA USB SLAVE PORT
The CMe3100 is configured via the integrated web interface. This is
easily reached via the local USB slave port (10) that is connected to a
PC. Connect the included USB cable between the computer and USB
slave port. After approximately 30 seconds, a removable disk will be
available on the computer. Open the folder on the removable disk
and run the file CMe3100-SETUP.EXE and follow the instructions.
When the installation is finished a browser with address
192.168.100.1 will be opened.
It is also possible to log in via the network that the product is connected
to. In this case, a DHCP server is needed in the network or that
CMe3100 has a static IP address configured. Find out which IP address
CMe3100 uses and enter it in a browser.

WIRING DIAGRAM

FACTORY RESET
Factory reset of the product can be done in the web interface or by
holding the button (15) pressed down at power-up. Hold for about 20
seconds. When green and red LEDs are flashing alternately, release the
button to execute the factory reset.

TROUBLESHOOTING
All LEDs are permanently off
Verify:
• That the product is powered up.
• If the product is in the first stage of the start-up process,
approximately 20 s.
Red LED is permanently on
• Verify no short-circuit of the M-Bus bus.
• Measure the voltage over the M-Bus master, voltage should be
between 24-30 VDC.
Red LED is flashing, the unit can not be accessed via LAN
• Is the CMe3100 configured with static IP or dynamic IP (dynamic
IP is the default).
• For static IP, check that there are no conflicts with the set IP
address.
• For dynamic IP, check that the CMe3100 is connected to a network
with a correctly working DHCP server.
