Please contact the manufacturer's support service for applications with nozzles that are higher
than indicated in the table.
Information concerning threaded connections
For devices with a threaded connection, it may be necessary - depending on the antenna size -
to first disassemble the horn and then mount it again after screwing in the device.
• When screwing in, turn by the hex bolt only.
• Tool: open-ended wrench 60 mm
• Maximum permissible torque: 60 Nm (44 lbf ft)
Parabolic antenna (FMR57)
Alignment
Ideally, the parabolic antenna should be installed vertically. To avoid interference reflections or for
optimum alignment in the vessel, the Micropilot can be swiveled by 15 ° in all directions with the
optional alignment device.
Information concerning nozzles
• Case 1: Ideally, the parabolic antenna should project fully out of the nozzle (1). Particularly when
using the alignment device, it is important to ensure that the parabolic reflector is projecting out of
the nozzle/ceiling so as not to inhibit alignment.
• Case 2: For applications with higher nozzles, it may be necessary to install the parabolic antenna
completely in the nozzle (2).
The maximum height of the nozzle ( H
max
) to the parabolic mirror should not exceed
500 mm (19.7 in). Interfering edges within the nozzle should be avoided.
