CAUTION
The LT31 transportation box contains the mounting kit including nuts,
washers and frangible mounting rods/foundation screws for installation
without
extension poles. Do not use these standard frangible mounting
rods when installing extension poles.
The transportation box of each extension pole contains frangible
mounting rods which are adapted to the specific extension length.
Be sure to use frangible mounting rods/foundation screws with a
contraction area of diameter 8 mm when a LTEP100 (1 m) extension is
used and frangible mounting rods/foundation screws with a contraction
area of diameter 9 mm when a LTEP200 (2 m) extension is used.
Installing LTEP100/200
In this section, LTEP100/200 specific installation instructions are given
which replace the sections Setting up Receiver Mast to Foundation and
Setting up Transmitter Mast to Foundation in the LT31 User´s Guide in
case receiv
er and/or transmitter unit is installed using extension poles.
All other information given in the LT31 User´s Guide remains valid also
for cases where extension poles are used.
Drilling Instructions
NOTE
The following instruction replaces the instruction in section Dowel
mounting on page 87 in a case where LTEP100/200 extension poles are
used.
1. Orientate the drilling template so that one of the drilling holes
points exactly towards the opposite installation place. On both
foundations, the instrument should be mounted afterwards in the
center of the foundation surface. The distance between the single
holes which point towards the opposite place, must match exactly
the desired baseline length of typically 30 m (50 m and 75 m
optional; see Figure 152 on page 283).
