Safety instructions

Use in accordance with the regulations

The T12 digital torque transducer is used exclusively for torque, rotational

speed, angle of rotation and power measurement tasks and control and

adjustment tasks directly connected thereto. Use for any additional purpose

shall be deemed to be not in accordance with the regulations.

Stator operation is only permitted with an installed rotor.

In the interests of safety, the transducer should only be operated as described

in the operating manual. 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.

Each time, before starting up the transducer, you must first run a project plan

ning and risk analysis that takes into account all the safety aspects of automa

tion technology. This particularly concerns personal and machine protection.

The transducer is not a safety element within the meaning of its use as

intended. Proper and safe operation of these transducers require proper

transportation, correct storage, assembly and mounting and careful operation.

This is a Class A product. In a domestic environment this product may cause

radio interference in which case the user may be required to take adequate

measures.

General dangers of failing to follow the safety instructions

The transducer corresponds to the state of the art and is fail‐safe. The

transducer can give rise to remaining dangers if it is inappropriately installed

and operated by untrained personnel.

Everyone involved with the installation, commissioning, maintenance or repair

of the transducer must have read and understood the operating manual and in

particular the technical safety instructions.

Remaining dangers

The scope of supply and performance of the transducer covers only a small

area of torque measurement technology. In addition, equipment planners,

installers and operators should plan, implement and respond to the safety

engineering considerations of torque measurement technology in such a way

as to minimize remaining dangers. Prevailing regulations must be complied

with at all times. Reference must be made to remaining dangers connected

with torque measurement technology.

In this Mounting instructions remaining dangers are pointed out using the

following symbols:

Symbol: DANGER

Meaning: Maximum danger level

Warns of an imminently dangerous situation in which failure to comply with

safety requirements will result in death or serious physical injury.

Symbol: WARNING

Meaning: Potentially dangerous situation

Warns of a potentially dangerous situation in which failure to comply with

safety requirements can result in death or serious physical injury.

Symbol: CAUTION

Meaning: Dangerous situation

Warns of a potentially dangerous situation in which failure to comply with

safety requirements could result in damage to property or some form of

physical injury.

Symbols for using advices and helpful information:

Symbol: NOTE

Means that important information about the product or its handling is being

given.

Symbol:

Meaning: CE mark

The CE mark enables the manufacturer to guarantee that the product com

plies with the requirements of the relevant EC directives (the declaration of

conformity is available at http://www.hbm.com/HBMdoc).

T12

A1979-7.1 en HBM

Symbol:

Meaning: Statutory marking requirements for waste disposal

National and local regulations regarding the protection of the environment and

recycling of raw materials require old equipment to be separated from regular

domestic waste for disposal.

For more detailed information on disposal, please contact the local authorities

or the dealer from whom you purchased the product.

Conversions and modifications

The transducer 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

The transducer must only be installed and used by qualified personnel, strictly

in accordance with the specifications and with safety requirements and

regulations. 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.

Qualified personnel means persons entrusted with the installation, fitting,

commissioning and operation of the product who possess the appropriate

qualifications for their function.

Prevention of accidents

According to the prevailing accident prevention regulations, once the T12

digital torque transducer has been mounted, a cover or cladding has to be

fitted as follows:

•The cover or cladding must not be free to rotate.

•The cover or cladding should avoid squeezing or shearing and provide

protection against parts that might come loose.

•Covers and cladding must be positioned at a suitable distance or so

arranged that there is no access to any moving parts within.

•Covers and cladding must also be attached if the moving parts of the

torque flange are installed outside peoples' movement and operating

range.

T12

A1979-7.1 enHBM

CAUTION

The protection against contact option, to prevent accidental contact,

must not be used as protection against bursting parts.

The only permitted exceptions to the above requirements are if the various

parts and assemblies of the machine are already fully protected by the design

of the machine or by existing safety precautions.

Warranty

In the case of complaints, a warranty can only be given if the torque

transducer is returned in the original packaging.

1 Scope of supply

•Digital torque transducer (rotor and stator)

•T12 Mounting Instructions

•Quick Start Guide for installing the T12 Assistant control software

•T12 system CD

•Mounting kit

•Test report

•Options:

- Speed measuring system, comprising optical rotational speed sensor and

speed kit (slotted disc, screwdriver, screw locking device, screws)

- Protection against contact

- Mounted coupling

2 Operation

The supplied T12 system CD contains the "T12 Assistant" control software.

You can use this software to:

•monitor the correct installation of the torque transducer

•set the signal conditioning (zero balance, filters, scaling)

•protect your settings or load the factory settings

•display and evaluate the measured values

Notes on installing the T12 Assistant on your PC can be found in the "T12

Assistant Control Software" Quick Start Guide. (pdf file on T12 system CD

and part of the “Setup Toolkit for T12" accessory).

Notes on the operation of the T12 Assistant can be found in the program's

online Help, which is called with function key F1 or via the menu bar.

For more information about connecting to fieldbus systems, please refer to the

“T12‐CAN bus/PROFIBUS" operating manual (pdf file on T12 system CD).

3 Application

The T12 digital torque transducer records static and dynamic torque at

stationary or rotating shafts measures rotational speed or angle of rotation,

including indication of the direction of rotation, and computes the power. It is

designed for:

•highly dynamic torque measurements when testing the performance and

functionality of engines and compound sets

•high‐resolution speed and angle of rotation measurements

•fast, dynamic performance measurements on engine and transmission test

rigs and roll test stands

Designed to work without bearings and with contactless digital signal

transmission, the torque measuring system is maintenance‐free.

The torque transducer is supplied for nominal (rated) torques of 100 N⋅m to

10 kN⋅m. Depending on the nominal torque, maximum speeds of up to

18 000 rpm are permissible.

The T12 torque transducer is reliably protected against electromagnetic inter

ference. It has been tested with regard to EMC according to the relevant

European standards, and carries the CE mark.
