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.
