Open the battery chamber on the back of the MSM12. Insert
the batteries as shown on the illustration opposite. Take care
that the batteries have the correct polarity. Improperly inserted
batteries may damage the device! If it is intended to store the
MSM12 for a long time, the batteries must be removed in order
to protect the device.
MSM12 with Bluetooth option:
Screw the factory-supplied aerial to the aerial connection. The aerial has a link by
which it can be moved into a favourable transmission position. Generally it is favour-
able to place the aerial in an upright position. For transport and storage the aerial can
be unscrewed.
5Connecting the MSM12 to the computer
The free of charge operating software for the MSM12 can be downloaded on our
Homepage www.henning-gmbh.de.
The drivers for the USB interface are installed together with the software, i. e., when
connecting the computer to the MSM12 using an USB-A-B cable the drivers are

6.1 Mode of operation
The rope sensor is based on a patented measuring procedure which, for the first
time, permits the carrying out of absolute weight measurements without calibration in
the rope. Inside the sensor there is a strain gauge the signals of which are condi-
tioned by the integrated electronics and are passed via the USB plug of the sensor to
the rope load evaluation unit MSM12.
Each rope sensor LSM is individually calibrated.
6.2 Connections
The LSM is provided with a 0.8 m cable for connection to the MSM12. The cable is
equipped with a USB-A connector. The sensor has no further connection options.
6.3 Handling
Please, take care that the LSM connector is free of dust, liquids etc. so that the con-
tact is not impaired.
In order to use the sensor in a rope, please proceed as follows:
1. Bring the clamping lever into the open position and insert the sensor into the
rope. If this is not possible, open the set screw by several turns. Now tighten
the set screw so far until the marking of the LSM corresponds to the desired
rope diameter on the type label.
2. Now close the clamping lever and take care that the rope is still running in the
groove of the sensor.

7Operation
The handling of the mobile rope load meter MSM12 is described below. For opera-
tion of the MSM12 using the optional software refer to the software operating instruc-
tions.
7.1 Installation of the rope load sensors LSM
In each LSM rope a rope load sensor must be installed as described in chapter 6.
Take care that you assign the connections of the rope sensors at the MSM12 in con-
tinuous and ascending order, starting with connection 1. For the use of the rope load
wizard it is important that you do not skip any connections.
7.2 Switching-on
In order to switch on the MSM12 mobile rope load meter please press the on/off
switch for minimum 3 seconds. The display now shows the Henning logo. After a
short time the display switches to the main display. The MSM12 is now ready for op-
eration.
To switch off please press the on/off switch for minimum 3 seconds again. The de-
vice switches off, the display lighting is extinguished. If the inserted batteries are run-
down, the MSM12 switches off automatically. The approaching switch-off is indicated
30 seconds in advance by a flashing weight display.
In order to avoid a damage of the MSM12 spent batteries should be replaced as
soon as possible by new ones. In order to guarantee the data storage of the real-time
clock of the MSM12 it should not be left more than 20 minutes without voltage sup-
ply. In the switched-off condition the run-down batteries supply the clock with voltage
for one week. The loads and adjustment records are stored in non-volatile memory in
the MSM12 and are maintained up to ten years without having to insert batteries.
7.3 Main display
Figure 1 shows the main display of the mobile rope load meter MSM12. In the upper
two lines of the main display the status bar indicator and the indication of the individ-
ual weight of each rope under the corresponding sensor number are displayed. Be-
low, in the centre, the total weight resulting from the individual weights is indicated. At
the right side and below the total weight three menu buttons SAVE, CONFIG and
ADJUST are to be found which will be described in detail below. In the lower left-
hand corner the time and date are displayed.

Mobile Rope Measurement MSM 12
Henning GmbH Page 9 2.0 / 3.2009
Figure 1: Main display
Die The individual weight display shows the measured load of each connected
rope load sensor. If no sensor is connected to the relevant measuring channel or if
the relevant rope load sensor is defective, Err1 is displayed. If the connected rope
load sensor is overloaded, Err2 is displayed.
The suspension ratio of the elevator can be selected by the user. The displayed
total weight is calculated by this factor. The individual weight display hereby remains
unaffected.
The total weight is the sum of all individual rope loads measured, if necessary con-
verted according to the suspension ratio. The output can be selected in different
weight units (kilogram (tons) or English pounds (short tons or long tons).
The maximum individual rope load display shows the actual load and the measur-
ing channel number of the sensor which is loaded with the highest weight in the rope
set. The minimum individual rope load display shows the corresponding informa-
tion for the rope with the lowest load.
The maximum deviation shows the absolute and percentage deviation of the rope
with the greatest deviation from the mean value of all ropes. The example in figure 1
shows a total weight of 1,516 kg distributed among 6 ropes. This means that under
ideal conditions each rope should carry 252 kg. However, the rope at measuring
channel 6 carries 380 kg, i. e. 128 kg corresponding to 52 % more load. (rounding
errors are possible)
If the mobile rope load meter LSM-XL is used (diameter range 16 – 24 mm) the rope
load meter must be switched over to this sensor type. The sensor type selected
(XL)appears on the display. When using LSM1 and LSM2 sensors this switching is
not required. In this case the display, where otherwise XL is indicated, remains blank.

7.4.2.3 Set suspension ratio
Under this menu item you can enter the suspension ratio of the elevator at which you
want to carry out measurements. The ratio is displayed on the main display; how-
ever, it is not permanently stored in the load meter. After a restart the load meter
starts automatically with a suspension of 1 : 1.
By means of the suspension ratio entered the displayed total weight is calculated.
The suspension ratio has no influence on the individual rope loads.

7.4.2.7 Set display units
The rope loads and total weights can be displayed in two different units. The unit
kilogram or tons respectively is preset. Alternatively you may change to the output in
the English weight unit pound and here you can select between short tons and long
tons.
This selection is permanently stored and after the restart of the load meter it is se-
lected by default.
Figure 12: Display unit setting
7.4.3 Rope load wizard
The rope load wizard will assist you in the uniform adjustment of the ropes. For this
purpose the wizard uses the current rope loads as the actual state and calculates a
new desired load for each rope. The changed load distribution in the ropes is already
taken into consideration when readjusting a rope. Due to a special calculating algo-
rithm it becomes possible that even after only one adjustment run all ropes bear the
same load. In addition, during each adjustment process the wizard searches for a
reference rope which does not have to be adjusted. The rope load wizard only be-
comes active for two or more ropes.
Figure 13: Rope load wizard
Tolerance field

Mobile Rope Measurement MSM 12
Henning GmbH Page 17 2.0 / 3.2009
In figure 13 you see the connected sensors – in this case 6 sensors. The evaluation
unit has determined rope 2 as the reference rope. (during the total adjustment proce-
dure channel 2 will never display a deviation; If you adjust rope 2 this has on the dis-
play only effects on the other measuring channels). It is not necessary that you adjust
this reference rope. After adjustment of all other ropes this will automatically bear the
correct load. All other ropes have to be adjusted in such a way that the relevant verti-
cal bar becomes minimal or can no longer be distinguished from the centre line, re-
spectively, (ideal setting) or it is positioned within the tolerance field that you have
determined, marked by the broken horizontal lines.
As soon as all ropes have been adapted with the desired accuracy you may leave
the rope load wizard by pressing "OK".
Figure 14: Storage of the rope load setting
After completion of the rope adjustment the question is displayed whether the rope
load wizard shall save a record of this adjustment process (see Figure 14). Apart
from time and date this storage records the loads of the ropes before and after the
adjustment. Press the YES button in order to store a record of the adjustment carried
out. If you decide against data logging, press the NO button. Using the button ID you
can assign a 16 digit alpha-numerical designation to the record, in order to easier find
the measurement again In both cases you return to the main display. In the internal
memory of the MSM12 you can store up to 100 adjustment records.

8Carrying-out of measurements
8.1 Installation position of the sensors in the rope
8.1.1 General conditions
The sensors must be mounted with a minimum distance of 200 mm to the cable joint
as a not vertically running rope can distort the precision of the measured results.
For an exact measuring result the sensor may only once be clamped into the
selected rope place.
> 200mm
< 200mm

Mobile Rope Measurement MSM 12
Henning GmbH Page 19 2.0 / 3.2009
8.2 Rope adjustment
On principle, take care that the sensors are mounted in that section of the rope in
which the rope exhibits a maximum length without intermediate deflections or traction
sheaves, as the ropes during stoppage cannot or only slightly balance between the
rope sections.
If, due to the elevator design, this is only possible to some extent, several rope ad-
justments one after the other have to be carried out. In this case the elevator must be
moved several times in order to balance the ropes beyond the traction sheave, too.
