2 Description of the LM-S lightning monitoring system
The LM-S lightning monitoring system continuously measures the strength of the current
flowing through the monitored conductor. Characteristics are used to determine the light-
ning characteristic. The LM-S detects and analyzes all important parameters of lightning
currents. This thereby allows you to assess the actual lightning current load of the system.
Components The LM-S (lightning monitoring system) consists of the following components:
– Evaluation unit (LM-S-A/C-3S-ETH)
– Up to three sensors (LM-S-LS-H)
– Optical connecting cables
The sensors are mounted on the down conductors that carry the lightning current. The sen-
sors record the magnetic field that occurs around the conductor due to the lightning surge
current.
The connecting cables transmit the measurement result to the evaluation unit.
The optical signal is converted into an electrical signal in the evaluation unit with O/E mod-
ule. Based on the values obtained, the evaluation unit determines the lightning characteris-
tic. Typical parameters include the maximum lightning current strength, the lightning current
rate of rise, the charge, and the specific energy.
Measuring method The internal measuring principle of the LM-S is based on the Faraday effect. Polarized light
in a specific medium is rotated through a magnetic field over a defined length and mea-
sured. The lightning monitoring system detects this change in the light signal and uses this
as the basis for the measured value results.
Remote monitoring The evaluation unit can be easily integrated into standard network systems via an RJ45
Ethernet interface. You can access the acquired data and configure the system remotely via
a web server, OPC UA or Modbus/TCP.
Hardware and software re-
quirements
Requirements for setting up the system
– Computer with network connection (standard Ethernet 10/100Base-T)
– Web browser (we recommend Mozilla Firefox)

3.1 Safety notes
WARNING: Electrical connection may only be carried out by qualified personnel
The electrical connection, startup, and operation of this device may only be performed by
qualified personnel.
Qualified personnel are persons who are authorized to start up, to ground, and to mark
devices, systems, and equipment according to the standards of safety technology. In ad-
dition, these persons must be familiar with all warning instructions and maintenance mea-
sures in this document.
Disregarding this warning may result in damage to equipment and serious personal injury.
NOTE: Risk of inaccurate measurements
Changes in the attenuation within the measuring path can result in inaccurate measure-
ments. A major cause of attenuation changes is pressure on the sheath or tension on the
cables of the connectors.
Install the cables in such a way that pressure or tension is at no time exerted on the cables.
This also applies during operation and maintenance work.
Mount and lock the plugs according to the instructions.
NOTE: Contamination of the FO connection
Always protect open plugs and couplings with dust protection caps. Store the dust protec-
tion caps in a sealable plastic bag.

3.2 Calibration factor
3.2.1 Sensor calibration factor
A calibration factor is printed on the rating plate of the sensor.
In order to ensure accurate evaluation, this factor must be entered during system configu-
ration (see “Sensor settings” on page 40).
Figure 3-1 Calibration factor (1)
•On the sensor, mark the input (1, 2 or 3) on the evaluation unit to which the sensor is to
be connected.
•Keep a note of the calibration factor so that it can be entered in the evaluation unit later.
3.2.2 Down conductor calibration factor
The LM-S sensors are calibrated for direct mounting on circular down conductors with di-
ameter d = 10 mm.
If the sensors are used with a different down conductor, you must include an additional fac-
tor in the software (see “Sensor settings” on page 40). This factor compensates for the mag-
netic field dependence through the geometric assignment of the sensor to the down con-
ductor.
This factor is dependent on the distance between the measuring path in the sensor and the
down conductor, and on the geometry of the down conductor.
To determine this factor, contact Phoenix Contact.
We recommend that you do not use down conductors with a width or diameter greater than
50 mm.
NOTE: The sensors are optimized for use on circular conductors with a diameter of
10 mm. If the sensor is used with a different down conductor the calibration factor must be
adjusted accordingly.

3.3.1 Mounting sensors
Figure 3-2 Alignment of the sensor on the conductor
NOTE: Make sure that the sensor is lined up correctly and in place. Secure the sensor so
that it cannot rotate around the live conductor. This is the only way to ensure optimum
measurement.
The sensor must be fixed securely and must be mounted on a fixed lightning down con-
ductor. The sensor must only be secured by means of the clips provided.
NOTE: Risk of inaccurate measurements
Install the sensors outside of the area affected by external magnetic fields. Use the mount-
ing inserts supplied.

Mounting on open down conductors
Figure 3-3 Mounting the sensor on an exposed down conductor
•Push the two mounting inserts (2) provided into the corresponding receptacles.
When mounting on circular down conductors, use the additional mounting inserts.
– Mounting insert (3) for down conductors with a diameter of around 10 mm.
– Mounting insert (4) for down conductors with a larger diameter.
•Position the sensor (1) so that the measuring path is perpendicular to the live conduc-
tor.
•Fix the sensor in place with the cable binders (5) provided.
Mounting on covered down conductors
•Obtain information about the exact position and location of the down conductor so that
you can position the sensor as precisely as possible.
•Position the sensor so that the sensor is perpendicular to the live conductor (see
Figure 3-2).
•Determine the “Down conductor factor” for this setup.
Use a mounting adapter to ensure that the sensor stays aligned and does not move during
operation.

3.3.2 Connecting the connecting cable to the sensor
To connect sensors to the evaluation unit, use connecting cable FOC-SJ:14-ST/HB02/...,
Order No. 1417723. This cable can be ordered in the necessary length. However, the cable
may not be shorter than 10 m or longer than 200 m.
For additional information, visit phoenixcontact.net/qr/1417723.
For harsh industrial applications, such as wind turbine generators, the connecting cable can
also be ordered in a protective hose variant. The cable is available in 10 m and 13 m lengths;
other lengths are available upon request.
More information can be found under:
– 10 m: FOC-ST:A-SJ:C-HB02/10 PR - 1423846, see: phoenixcontact.net/qr/1423846
– 13 m: FOC-ST:A-SJ:C-HB02/13 PR - 1426160, see: phoenixcontact.net/qr/1426160
Observe the technical characteristics of the cable during installation and startup.
•Remove the dust protection caps on the sensor and the connecting cable.
Figure 3-5 Connecting the connecting cable to the sensor
•Insert the connecting cable into the push-pull connection of the sensor until the lock
snaps in. Make sure that the coding is in the correct position.
NOTE: Damage to the connecting cable
Observe the minimum bending radius when installing the connecting cable, otherwise ir-
reparable damage may be caused to the cable.
NOTE: Risk of inaccurate measurements
Install the cables in such a way that pressure or tension is at no time exerted on the cables.
This also applies during operation and maintenance work. We recommend installing ca-
bles in conduits or cable ducts.
NOTE: Contamination of the FO connection
So as to prevent contamination of the transmit and receive elements, do not remove the
dust protection caps until just before the connectors are connected. During maintenance
work, store them in a sealable plastic bag.
Clean contaminated transmit and receive elements, e.g., using a ferrule cleaner (FOC-
TOOL-FERRULECLEANER-2.50, Order No. 1407029).
