6.B Starting the Device

In order to switch on the MSM12 mobile rope load meter please press the on/off switch for
a minimum of 3 seconds. The display now shows the Weight Watcher logo as well as a
progress bar. After a short time the display switches over to the main display. The MSM12
is now ready for operation.

To switch off please press the on/off switch for minimum 3 seconds again. The device
switches off and the display lighting is extinguished. If the batteries are run-down, the
MSM12 switches off automatically.

 Henning GmbH & Co. KG page 10 19/02/2019

6.C Main Display

Below, the main display of the mobile rope load evaluation unit MSM12 is shown. The upper
two lines display the status bar indicating the individual weight of each rope under the cor­responding measuring chanel number.

Below, in the centre, the total weight resulting from the individual weights as well as the
maximum individual load, minimum individual load and the maximum deviation and the cor­responding measuring channel numbers are indicated. At the right side four menu keys are
to be found which will be described in detail later. In the lower left-hand corner the charge
status of the batteries is displayed. On the upper left below the status bar the selected sus­pension ratio is shown.

The individual sensor display shows the measured load of each connected rope load sensor.

Please note: The load in the status bar on top will not be calculated on the basis of
the selected suspension ratio.

If a connected sensor is defective, ERR will be displayed. The yellow warning­triangle will show up, as soon as the calibration of the corresponding sensor has
expired.

A touch on one of the sensor-keys in the status bar will open a separate window showing
the data of the corresponding sensor (see also 6.C.1 “sensor-information”).

The suspension ratio of the elevator can be selected manualy by the user. The displayed
total weight is calculated by this factor. The individual weight displayed per sensor remains
unaffected (see also 6.D “Choosing Suspension Type”).

The total weight is the sum of all individual rope loads measured, converted according to
the suspension ratio (if applicable). The output can be selected in different weight units
such as kilogram, tons, Newton, English pounds, short tons or long tons.

The maximum individual rope load shows the actual load and the measuring 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 information for the rope with the lowest
load.

The maximum deviation shows the deviation (absolute as well as percentage) of the rope
with the greatest deviation from the average calculated from all ropes. The example in figure
shows a total weight of 1,529 kg distributed among nine ropes. This means that under ideal
conditions each rope should carry 177 kg. However, the rope at measuring channel 3 carries
245 kg, i. e. 68 kg (absolute) or 39 % more load(rounding errors possible).

The calibration warning will be displayed, if the last calibration of the evaluation unit
has been one year ago (or longer).

6.D Choosing Suspension Type

In this menu section one can enter the suspension ratio of the elevator at which you want to
carry out measurements. The ratio is displayed on the main display; however, it is not per­manently stored in the evaluation unit. After a restart the evaluation unit will automatically
be displaying a suspension of 1 : 1.
By means of the suspension ratio the displayed total weight is calculated. The suspension
ratio has no influence on the individual rope loads.

6.E Saving Data

By touching the key „save“, a selection menu opens, in which one can choose between the

options “save current weight distribution” and “measurement of load curve”, if you have pur-

chased the optional software “curve storage”. If not, the unit switches automatically to the

allocation of the project-ID (see also 6.E.3).

6.G Rope Adjustment Wizard

The rope load wizard will assist you with the uniform adjustment of the ropes. For this pur­pose the wizard uses the current rope loads as the actual state and calculates a new setpoint
load for each rope. The changed load distribution in the ropes is already taken into consid­eration when readjusting one of the ropes. Due to a special algorithm it will be possible that
all ropes bear the same load after only one adjustment run. Also, during each adjustment
process the wizard determines a reference rope which does not have to be adjusted (rope
4 in the illustration). The rope load wizard will only be activated when two or more sensors
are connected.

7 Operating the Sensors

7.A General Notes

Operation

The rope load sensors are based on a patented measuring method which allows to carry
out absolute measurements without the nned to calibrate the system with weights. The
sensor contains a strain gauge, the signals of which are beeing conditioned by integrated
electronics and transmitted via the USB connector of the sensor to the evaluation unit
MSM12. Each sensor is calibrated individually.

Connections
Each LSM sensor features cable with USB-A connector to connect them to the evaluation

unit MSM12. The sensors have no other connecting options.
Handling
To ensure that there is always good electrical contact please keep the sensor plugs free

from dust, liquids etc..

 Henning GmbH & Co. KG page 26 19/02/2019

7.A.1 Positioning of Sensors on the Rope

The sensors must be mounted with a minimum clearance of 200 mm to the rope clamps, as
a non perpendicular running cable may distort the result of the measurement.

! Attention: for an accurate measurement, the sensor may be clamped only once onto

a particular space in a rope.

7.A.3 Rope Adjustment

Generally, the sensors should be mounted in the section of the rope which features maxi­mum lengths without intermediate deflections or traction sheaves, as the ropes will be bal­ancing out only very slightly or none at all during standstill.

If this is not possible due to the layout of the elevator, several rope settings may be carried
out in succession. In between the adjustment procedures, the elevator should be driven
several times in order to compensate the ropes loads across the traction sheave.

7.A.4 Friction / Determination of Weight

Due to heavy friction of the car or the counterweight in the guide rails the measuring
result may be negatively affected. In such a case it is prefered to determine the weight
during a constant travel. This effect is found particularly often in the case of rucksack
guides. With roller guides this effect is found generally less frequently than with slide
type guides.

If possible, clamp the sensors onto the rope directly above the load to be measured (>= 200
mm) and subsequently travel a short distance upward with constant speed. If there is no
difference between the indicated load during the constant travel and while standing still,
there is no friction to speak of in the guides and it will not be necessary to carry out the
measurement during travel.

If there is a significant difference between the travel and the standstill value, make a note
of the value measured during the upward travel and then start a downward travel with con­stant speed. Make a note of this value too.

The average of the readings obtained during upward and downward travel is the real
weight without friction.

By this trick of traveling upwards and downwards and the subsequent determination of an
average value you have eliminated the dynamic and static friction of the elevator from the
measurements.

! Attention: In the case of multi-suspensions, please take extra special care that the

sensors are not overrun during the measuring travels!

 Henning GmbH & Co. KG page 36 19/02/2019

7.B Installation of Sensors LSM1 und LSM2

1. Bring the clamp lever into the “open” position. Place the sensor onto the

rope. If this is not possible, open the adjustment-screw several turns. When
the sensor is placed on the rope, turn the adjustment-screw in such a way,
that the marker matches the apropriate rope diameter on the label. This is
only a rough adjustment, the fine tuning will be done by the green o-ring on
the adjustment-screw.

2. Now close the clamp lever and taking care that the cable still runs correctly in the
sensor groove.

3. Connect the sensor LSM to the evaluation unit MSM12 via the USB cable.

Step 1

Step 2

Step 3

 Henning GmbH & Co. KG page 37 19/02/2019

After installation, the correct sensor adjustment should be verified, to ensure that the sen­sor has been fitted with the right force. The clamping force is correct, if the edge of the ad­justment screw’s silver cylinder is positioned in the center of the green o-ring. If the edge
of the silver cylinder is not positioned inside the O-ring, the clamping force is wrong and
the installation should be repeated.

The following pictures show correctly and incorrectly adjusted rope load sensors:

Correctly adjusted:

 Henning GmbH & Co. KG page 38 19/02/2019

7.C Installation of Sensors LSM-XL

Open both levers 1 as well as lever 2, open strap 3. Adjust the sensor by means of the ad­justment screw 4 roughly to the rope diameter and mount the sensor onto the rope. Close
strap 3 and after lever 2.

7.D Installation of Sensors LSM-BELT

Place the sensor onto the belt and close the strap at the side. Make sure that the belt is
positioned correctly in the in the sensor’s corresponding groove. If the belt has only
grooves on one side, the flat side should be facing towards the sensor body.

After installation, the correct sensor adjustment should be verified, to ensure that the sen­sor has been fitted with the right force. The clamping force is correct, if the edge of the
adjustment screw’s silver cylinder is positioned in the center of the green o-ring. If the edge
of the silver cylinder is not positioned inside the O-ring the sensor is incorrectly mounted.
