2.3.3 Mounting rope probes
"
Caution!
If there is a risk of electrostatic discharge from the product, then both process connection and
rope must be earthed before the probe is lowered into the silo.
Insert probe
• Uncoil rope and lower it slowly and
carefully into the silo.
• Do not kink the rope.
• Avoid any backlash, since this
mightdamage the probe or the silo fittings.
• If possible, make a visual check to see that
the rope has not tangled or is lysing such
that it can knot when the level falls. This
is particulary important if a flange was not
used. Re-insert the proce is necessary.
2.3.4 Mounting rope probes in a partially full silo
It is not always possible to empty a silo which is already in operation. Because the probe can be
turned in the threaded boss, it can also be mounted when the silo is only partially filled. In order
to avoid problems when Levelflex is mounted into a partially full silo, the following measures
should be taken:
• Mount when the silo is as empty as if possible. A minimum of 2/3 of the silo must be emtpy.
Insert probe
• If possible, make a visual check to see that
the rope has not tangled or is lysing such
that it can knot when the level falls. This
is particulary important if a flange was not
used. Re-insert the proce is necessary.
• Screw the flange to the counterflange on
the nozzle.
!
Note!
• After mounting, map must be made should the installation conditions require it.
• Before full accuracy is obtained the probe must hang fully extended.
