Figure 3-11: How to attach the device if the antenna diameter is larger than the process connection size
Special equipment needed:
• 3 mm Allen wrench (not supplied)
WARNING!
If you attach the antenna in a closed space, make sure that there is a good airflow in the area.
Make sure that a person not in the silo can always hear you.
INFORMATION!
If the antenna is larger than the process connection, we recommend that you use an antenna
extension. It is possible that there is not sufficient space to tighten the antenna locking screw.
• Make sure the flange on the nozzle is level.
• Drop antennas without an antenna extension: Drop antennas without an antenna extension: Remove the three locking screws with a 3 mm

• Remove the antenna from the part below the flange (if there are no antenna extensions). If the
device has one or more antenna extensions, remove the locking screw from the top antenna
extension and remove the antenna and the antenna extensions from the part below the flange.
The antenna is not attached to the device. If the device has a Drop antenna, make sure that
i
the O-ring stays in the groove on the antenna or antenna extension.
• Align the gasket correctly with the flange facing of the nozzle.
• Put the device carefully on the silo flange. Do not attach the device flange to the silo yet.
• Go inside the tank. If you attach the antenna in a closed space, make sure that there is a good
airflow in the area.
• Attach the antenna to the part below the flange. We recommend that a person holds the device
on the top of the tank.
• Go to the top of the tank. Lift the device a small distance.
