When lowering the rope probe into the vessel, observe the following:
• Uncoil rope and lower it slowly and carefully into the vessel.
• Do not kink the rope.
• Avoid any backlash, since this might damage the probe or the vessel fittings.
Mounting rope probes in a partially full silo
It is not always possible to empty a silo which is already in operation. If a minimum of
2/3 of the silo is empty, it is possible to install the probe into the partially filled silo. If
possible, make a visual check after the installation to see that the rope has not
tangled or is lying such that it can knot when the level falls. Before full accuracy is
obtained the probe rope must hang fully extended.
6.2.4 Mounting the "Sensor remote" version
This section is only valid for devices of the version "Probe Design" = "Sensor remote"
(feature 600, option MB/MC/MD).
For the version "Probe design" = "Sensor remote" the following is supplied:
• The probe with the process connection
• The electronics housing
• The mounting bracket for wall or pipe mounting of the electronics housing
• The connection cable (length as ordered). The cable has got one straight and one angled
plug (90°). Depending on the local conditions the angled plug can be connected at the
probe or at the electronics housing.
L
CAUTION
The plugs of the connection cable may be damaged by mechanical stress.
‣
Mount the probe and the electronics housing tightly before connecting the cable.
‣
Lay the cable such that it is not exposed to mechanical stress. Minimum bending
radius: 100 mm (4").
‣
When connecting the cable: Connect the straight plug before the angled one. Torque
for both coupling nuts: 6 Nm.
Probe, electronics and connection cable are adjusted to match each other. They are
marked by a common serial number. Only components with the same serial number
shall be connected to each other.
If the measuring point is exposed to strong vibrations, an additional locking
compound (e.g. Loctite 243) can be applied at the plug connectors.
