1 Safety instructions

In cases where a breakage would cause injury to persons or damage to equip

ment, the user must take appropriate safety measures (such as fall protection,

overload protection, etc.). For safe and trouble‐free operation, the load cell has

to be correctly transported, stored, sited and installed and must also be care

fully operated and maintained.

It is essential to comply with the relevant accident prevention regulations. In

particular you should take into account the limit loads quoted in the specifica

tions.

Use in accordance with the regulations

The C16i... type digital load cell is conceived for weighing applications. Use for

any additional purpose shall be deemed to be not in accordance with the regu

lations.

In the interests of safety, the load cell must only be operated as described in

the Mounting instructions. It is also essential to observe the appropriate legal

and safety regulations for the application concerned during use. The same

applies to the use of accessories.

Take into account the maximum limit loads given in the Technical data. The

technical data for the load cell applies within the specified load limits only.

The electronic system processing the measurement signal must be designed

such that no consequential damage is caused by the failure of the measure

ment signal.

The load cell can be used as machine components. Please note that in these

cases, in order to achieve high sensitivity, the load cell has not been designed

with the safety factors normally applied in machine design.

The digital load cell is not a safety element within the meaning of its use as

intended. Proper and safe operation of this load cell requires proper transporta

tion, correct storage, assembly and mounting and careful operation and main

tenance.

Safety instructions

4A05516_01_Y00_01 HBM: public C16i

General dangers due to non‐observance of the safety instructions

The C16i... load cell correspond to the state of the art and are fail‐safe. The

load cell can give rise to residual dangers if it is inappropriately installed and

operated by untrained personnel.

Everyone involved with the installation, commissioning, maintenance or repair

of a force transducer must have read and understood the Mounting Instructions

and in particular the technical safety instructions.

Residual dangers

The scope of supply and performance of the load cell covers only a small area

of weighing technology. In addition, equipment planners, installers and opera

tors should plan, implement and respond to the safety engineering consider

ations of weighing technology in such a way as to minimize residual dangers.

Prevailing regulations must be complied with at all times. There must be refer

ence to the residual dangers connected with weighing technology.

Environmental conditions

In the context of your application, please note that all materials which release

chlorine ions will attack all grades of stainless steel and their welding seams. In

such cases the operator must take appropriate safety measures.

Conversions and modifications

The load cell must not be modified from the design or safety engineering point

of view except with our express agreement. Any modification shall exclude all

liability on our part for any damage resulting therefrom.

Qualified personnel

This load cell is only to be installed by qualified personnel strictly in accordance

with the technical data and with the safety rules and regulations. It is also es

sential to observe the appropriate legal and safety regulations for the applica

tion concerned. The same applies to the use of accessories.

Qualified personnel means persons entrusted with the installation, fitting, com

missioning and operation of the product who possess the appropriate qualifica

tions for their function.

Safety instructions

C16i A05516_01_Y00_01 HBM: public 5

Prevention of accidents

Although the specified breaking load in the destructive range is several times

the nominal capacity, the relevant accident prevention regulations from the

trade associations must be taken into consideration.

General hints

SPlease handle the load cell carefully.

SUse appropriate lifting gear when mounting the weighing device.

SDo not overload the load cell, not even for a short time (e.g. due to

unevenly distributed supporting loads).

SIf required, use supporting elements (dummies) of the same height for

alignment purposes.

The C16i... is a pendulum load cell designed to automatically restore the

mounting construction to a stable initial position in the case of a lateral dis

placement of the load introduction (= skewing of the load cell). The maximum

permissible lateral displacement or skewing (see chapter 8 “Dimensions”) 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 ap

propriate 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 and 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 (see chapter 8 “Dimensions”).

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 en

closed 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 pre

venting 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.
