2. Safety

WARNING!

Before installation, commissioning and operation, ensure

that the appropriate temperature transmitter has been

selected in terms of measuring range, design and specic

measuring conditions.

Non-observance can result in serious injury and/or

damage to the equipment.

WARNING!

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.

EMC directive 2004/108/EC, EN 61326 Emission

(Group 1, Class A) and Immunity (industrial locations)

Further important safety instructions can be found in the

individual chapters of these operating instructions.

2.1 Intended use

The temperature transmitter T24.10 is a congurable transmitter for

use with resistance thermometers (RTD) and resistance sensors.

The temperature transmitter has been designed and built solely for the

intended use described here, and may only be used accordingly.

The technical specications contained in these operating instructions

must be observed. Improper handling or operation of the instrument

outside of its technical specications requires the instrument to be

taken out of service immediately and inspected by an authorised

WIKA service engineer.

2. Safety

WIKA operating instructions temperature transmitter, model T24 7

2370242.09 08/2013 GB/D

If the instrument is transported from a cold into a warm environment,

the formation of condensation may result in instrument malfunction.

Before putting it back into operation, wait for the instrument

temperature and the room temperature to equalise.

The manufacturer shall not be liable for claims of any type based on

operation contrary to the intended use.

2.2 Personnel qualication

WARNING!

Risk of injury if qualication is insucient!

Improper handling can result in considerable injury and

damage to equipment.

■

The activities described in these operating instructions

may only be carried out by skilled personnel who have

the qualications described below.

■

Keep unqualied personnel away from hazardous

areas.

Skilled personnel

Skilled personnel are understood to be personnel who, based on

their technical training, knowledge of measurement and control

technology and on their experience and knowledge of country-specic

regulations, current standards and directives, are capable of carrying

out the work described and independently recognising potential

hazards.

Special operating conditions require further appropriate knowledge,

e.g. of aggressive media.

regulations, the appropriate existing codes or regulations

must also be followed.

2. Safety

WIKA operating instructions temperature transmitter, model T24 9

2370242.09 08/2013 GB/D

WARNING!

Protection from electrostatic discharge (ESD) required.

The proper use of grounded work surfaces and personal

wrist straps is required when working with exposed

circuitry (printed circuit boards), in order to prevent static

discharge from damaging sensitive electronic components.

To ensure safe working on the instrument, the operating

company must ensure

■

that suitable rst-aid equipment is available and aid is

provided whenever required,

■

that the operating personnel are regularly instructed

in all topics regarding work safety, rst aid and

environmental protection and knows the operating

instructions and, in particular, the safety instructions

contained therein.

DANGER!

Danger of death caused by electric current

Upon contact with live parts, there is a direct danger of

death.

■

Electrical instruments may only be installed and

connected by skilled electrical personnel.

■

Operation using a defective power supply unit (e.g.

short circuit from the mains voltage to the output

voltage) can result in life-threatening voltages at the

instrument!

WARNING!

Residual media in dismounted instruments can result in

a risk to persons, the environment and equipment.Take

sucient precautionary measures.

Do not use this instrument in safety or Emergency Stop

devices. Incorrect use of the instrument result in injury.
