Operating and service instructions | LMS 120 3
Safety notes
The following points must be observed for safety during connecting and operating the device. Read the notes
carefully before commissioning the device. The installer is responsible for any damage caused by improper use or
application of the device.
Mains
voltage
Operate the device only with the mains voltage intended (see 8. Technical data;
page 17). The device may only be connected to the mains once all connections
have been established. There is a risk of fire in the event of incorrect mains voltage.
Mains cable
It must be ensured that the mains cable is not damaged. Devices with damaged
mains cables must be disconnected from the mains (disconnect the mains plug)
and made secure before re-commissioning. There is a danger to life from electric
shock.
Earthing
The device must be earthed as required by regulations or connected to a suitable
potential equalisation. The DIN VDE 100 and the country-specific regulations must
be observed. There is a risk of excess voltage.
Place of
installation
Protect the device from humidity, dripping and spray water. Do not place any
objects on the device. Do not install the device near strong sources of heat. Do not
expose it to direct sunlight.
There is a risk of fire.
Cleaning
Disconnect the mains plug before cleaning the device. Use a dry cloth for cleaning
and clean the surface only. There is a danger to life from electric shock when
coming into contact with parts inside the device.
Connections
Incorrect wiring of the connections may result in faults or defective devices. The
manufacturer accepts no liability for accidents that are caused by incorrectly
installed or improperly maintained devices. The manufacturer accepts no liability
whatsoever if the system is incorrectly used or programmed in a way that is not
safe.
Ventilation
The heat created in the device is dispersed sufficiently. Do not install the device in a
cabinet with insufficient heat extraction or near sources of heat. (see 3.1.
Mechanical installation and 3.2. Electrical connection; from page 5). There is a risk
of fire.
Operation
Correct operation requires that the transparent front lid of the LMS 120 is closed to
ensure protection category IP65.
Repairs
Installation, modification, repairs or maintenance must be carried out in accordance
with the regulations of the manufacturer. Any disassembly and repair attempts
without the manufacturer’s approval result in the warranty claim becoming null and
void. Tampering with the device may put the electric safety of the device at risk.
The manufacturer is not liable for accidents of the user on the open device.
Electronic devices should not be disposed of with domestic waste. They must be disposed of in
accordance with the country-specific directives. Please discard this device at the intended collection
points for disposal when no longer in use. For discarded electric and electronic devices, Directive
2002/96/EC of 27 January 2003 applies in the European Union.
When conducting welding work on the district heating pipeline, the LMS 120 MUST be deactivated and
the measuring lines MUST be disconnected. Otherwise, the LMS 120 and other connected devices may
be damaged.

•LMS 120 monitoring device with pre-installed mains cable
•Plug connector - insert for alarm terminal
•Plug connector - inserts for monitoring channels 1 and 2 terminals
•Operating instructions
•Drilling template
2. General
The LMS 120 is suitable for monitoring two sensor wires in district heating pipelines. These may be executed in accordance with the
NORDIC or BRANDES system. The so-called SWISS system corresponds to the Nordic system with one isolated conductor.
The technical design allows monitoring of two different system types at the same time. As such, it is possible to connect one line with the
NORDIC system on measurement channel 1 and one line with the BRANDES system on measurement channel 2, for instance.
The system is based on measuring resistances between monitoring conductors and the metal medium pipe or the resistances of
measurement loops. All measured values can be read from the display.
(see 4.2. Operation menu; page 8)
2.1. System design
The LMS 120 has measurement channels operating free of potential to increase measurement precision and minimise the influence of
parasitic current measurements in the pipe.

The current status and the measurements can be read from the display. The 5 LEDs to the left of the display
provide a quick overview of the current device status.

3. Installation
3.1. Mechanical installation
The mechanical installation of the LMS 120 monitoring device
can be carried out on an even dry wall (drilling template) or
alternatively in a control cabinet.
At the place of installation, the device must be protected
against humidity (formation of condensation), strong dust and
strong electromagnetic fields. The safety notes, protection
measures and notes stated in these operating instructions
must be observed (see Safety notes; page 3). The housing lid
must be removed for fastening.
The installation must be carried out with fasteners that are
suitable for the respective substrate.

Note:
The 12V terminal is reserved for a special
version of the LMS 120. It must not be used.
The Alarm terminal can be charged with an
ohmic load of up to 2A/ 30V.
Fig. 4 (Wiring diagram)
3.2.2. Earth connection
To ensure smooth operation, the earth contact (pipe) of every measurement circuit must be connected with the
associated pipeline. When replacing existing leakage measurement systems, it is mandatory to check whether an
effective earth connection to the relevant pipe exists. Each measurement channel requires its own connection with
the pipeline.
3.2.3. Power
Finally, the device plug has to be inserted into a socket. The LMS 120 can be operated with an alternating current
of 90…240 V AC.
3.2.4. Commissioning
After the mechanical and electrical installation, the LMS 120 parameters need to be set. The procedure is
described in Section 4.3. Quick parameter setting on page 9.

Operating and service instructions | LMS 120 7
4. Operation
The LMS 120 displays information in various menus in a clear manner. 7 keys, 5 status displays (LED) and one
clear text display are arranged on the front plate. The current measurement values can be called up and operating
data set with the keys. The status displays (LED) provide a quick overview of the status of the line connected.
All detailed information and the parameter setting menus are shown by the info display.
