Installation and First Start-Up
12.
If the installation check shows that the magnetic side of the tape rubs against the sensor, first increase
the offset between the sensor and the tape. Up to 5 cm are acceptable without problems. If this meas-
ure is not successful, it is probable that the tape is not suspended straight in the shaft. You can easily
check that by taking the tape out of the guiding rail and performing an inspection travel along the lifting
height. While doing this, observe the distance between the tape and the sensor. Also make sure that the
tension of the tape is sufficient. If the tape is fixated too loosely, this complicates correct guiding and a
high offset between the tape and the sensor is necessary.
13.
Clean the tape after the mounting. Use a clean and dry cloth. Start at the shaft head and go down the
complete height in inspection mode pulling the magnetic tape through the cloth with a slight pressure.
Especially after metal construction works in the shaft you should clean the tape. Metal particles will ad-
here to the magnetic tape.
14.
Repeat the cleaning process before setting the elevator into operation.
15.
Check the function of the magnetic tape presence detector. To do this, pull the tape about 60 mm up-
wards until the bolt of the position switch is actuated. Leave the shaft pit and make sure that all doors
are closed. Try to move the cabin electronically. This must not be possible. Go back to the shaft pit and
make sure that the tape clamp with the spring is set back into the correct vertical position in relation to
the position switch and the crossbeam and reset the bolt into the original position with a screw driver.
Leave the shaft pit and make sure that all doors are closed. Try again to move the cabin electronically.
This must now be possible.
WARNING!
Observe the applicable safety requirements for entering the shaft pit
during this step.

Unguided variant
The unguided LIMAX44 RED is mounted on a guide rail or other support. Since the mounting is strongly de-
pendent on the environment, the details cannot be dealt with in this chapter. It is the user's responsibility to en-
sure that the system is properly installed in accordance with the instructions given in this chapter.
1.
Fasten the tape in the shaft so that the position is continuous upwards.
Clean the surface so that it is free of dust, grease, oil or other separating agents and allow the surface
to dry if necessary.
Before mounting, check the correct order of the tape segments (A bottom, B centre, C top) and their
orientation. The printed arrows must point to the head of the shaft.
Fig 16: Correct direction of magnetic tape
At the transition points between two tape segments, disconnect the protective pole at the marked point
before sticking the magnetic tape. The optimum contact pressure is 4 - 5 kg/cm

.
In the case of longer measuring ranges consisting of more than one tape segment, care must be taken
to ensure that the segments are not laterally offset at the transition between the two segments and are
close to each other at the ends as shown in the following figure.
