General hints

D Please handle the load cell carefully.
D Use appropriate lifting gear when mounting the weighing device.
D Do not overload the load cell, not even for a short time (e.g. due to unevenly distributed supporting
loads).
D If required, use supporting elements (dummies) of the same height for alignment purposes.
The C16 is a pendle load cell designed to automatically restore the mounting construction to a stable
initial position in the case of a lateral displacement of the load introduction (= skewing of the load cell).
The maximum permissible lateral displacement or skewing (refer to Dimensions = Chapter 5) must
not be exceeded, otherwise the load cells or load introduction parts might be damaged. The easiest
and most common solution for this problem are the appropriate stops on the mounting construction
(weighing platform) which must be carefully adjusted within the specified values.
With the C16i, we recommend the use of EPO3/50t + C16/EPU44A or C16/ZOU44A mounting
accessories from HBM, because they permit easy mounting. The rotation stop device welded onto
the load cells and the dowel pin provided are also suitable for this model type (refer to Dimensions
= Chapter 5).
Preparation work for mounting:
When using EPO3/50t + C16/EPU44A or C16/ZOU44A to introduce and carry off the load, the
following preparations have to be made:
A dowel pin is enclosed in the packing for every load cell. This dowel pin and the rotation stop welded
onto the load cell prevent a potential transducer microrotation, thus preventing the cable from being
damaged. Use a hammer to drive in the dowel pin until it rests in the load introduction part's pocket
bore. Radially position the open side of the dowel pin.
Position of rotation stop dowel pin:
!
The bore depth ensures correct fitting of the pin. Only one load introduction part per load cell must
be equipped with this pin. This load introduction part must be mounted below the load cell to enable
the dowel pin to engage into the rotation stop recess (refer to Dimensions = Chapter 5). No pin must
be introduced into the bore on the upper load introduction part.
Please also refer to and comply with the special notes at the end of this chapter.
The areas or foundations below the lower load introduction part (for carrying off the load) and above
the upper load introduction part should be as even and level as possible. With areas complying with
these quality requirements, it is also possible to install or screw--fasten the load introduction parts
directly onto concrete so that no additional plates are needed.
Practically drill the required borings for securing and fixing on the weighbridge resp. tank and base
plate before you mount the weighing platform. The dimensions for use with EPO3/50t + C16/EPU44A
or C16/ZOU44A are as shown in the dimensioned drawings in chapter 5.
