Mounting Preparation - HBM RTN/M2 Series Mounting Instructions

Mounting preparation

4 Mounting preparation
CAUTION
The weighing modules are delivered completely assembled, however, without a
load cell. Instead of the load cell, a dummy has been assembled into the
weighing module, which is capable of taking up the specified loads. Before the
weighing module is mounted underneath the tank, vessel or silo, check
whether dummy replacement through the load cell will still be possible even if
the tank is placed on the weighing module. In order to effect the replacement, a
suitable lifting device is necessary that is capable of lifting the tank by at least
10 mm. Pipe connections mounted on the tank or the feed‐in or discharge sys­
tems have to be vertically movable or separable.
Notice
If this is not the case, the dummy must be replaced by an appropriate RTN
load cell already before the weighing module is mounted.
General mounting preparations
S Ensure that the assembly/siting areas provided are clean, level and horizon­
tally aligned. Any askew positions can be compensated for, depending on
the assembly situation, for example by appropriate wedges and compensa­
tion plates (weld in position) or by grinding down the assembly area. How­
ever, module plates must not be ground down under any circumstances.
S The foundations / basic construction and the connection of the
superstructure must be sufficiently rigid in order to avoid deformations (e.g.
deflections) under load.
S In order to provide for fitting and assembly free from any constraining
forces, the mounting bores on the basic construction and the tank connec­
tion must be sufficiently aligned.
