WARNING!

GB

2.1 Intended use

The pressure transmitter is used to convert pressure into an electrical signal.

The instrument 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.

Before installation, commissioning and operation, ensure that the appropriate pressure
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!

■

Open the connections only after the system has been depressurised

■

Observe the working conditions in accordance with Chapter 3 "Specications".

■

Always operate the pressure transmitter within the overpressure safety range.

Further important safety instructions can be found in the individual chapters of these
operating instructions.

The manufacturer shall not be liable for claims of any type based on operation contrary to the intended
use.

2. Safety

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.

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.

2.3 Special hazards

WARNING!

For hazardous media such as oxygen, acetylene, ammable or toxic gases or liquids,
and refrigeration plants, compressors, etc., in addition to all standard regulations, the
appropriate existing codes or regulations must also be followed.

WARNING!

Residual media in the dismounted pressure transmitter can result in a risk to persons, the
environment and equipment.
Take sucient precautionary measures.

5. Transport, packaging and storage

5.1 Transport

Check the pressure transmitter for any damage that may have been caused during transportation.
Obvious damage must be reported immediately.

5.2 Packaging

Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in installation

site, sending for repair).

5.3 Storage

Permissible conditions at the place of storage:

Storage temperature: -40 ... +85 °C

GB

WARNING!

Before storing the instrument (following operation), remove any residual media. This is of
particular importance if the medium is hazardous to health, e.g. caustic, toxic, carcinogenic,
radioactive, etc.

CAUTION!

GB

6.1 Making the mechanical connection

■

Remove the protection cap not until shortly before installation. During
installation, ensure that the diaphragm is not damaged (with model
D-11-7).

■

The sealing faces at the instrument have to be undamaged and clean.

■

Only ever screw in, or unscrew, the instrument via the spanner ats.
Never use the case as a working surface.

■

The correct torque depends on the dimensions of the pressure connec­tion and the gasket used (form/material).

■

When screwing in, do not cross the threads.

■

For information on tapped holes and welding sockets, see Technical
Information IN 00.14 at www.wika.com.

Prior to commissioning, the pressure transmitter must be subjected to a visual inspection.

■

Check the diaphragm for any visible damage, since this is a safety-relevant component.

■

Leaking uid is indicative of damage.

■

Only use the pressure transmitter if it is in perfect condition with respect to safety.

Required tool: Open-ended spanner (spanner width 27 or 41), screwdriver

6. Commissioning, operation

Types of sealing

Parallel threads Tapered threads

per EN 837

Correct sealing of the process connections with parallel threads at the sealing face  must be made using
suitable at gaskets, sealing rings or WIKA prole sealings.
The sealing of tapered threads (e.g. NPT threads) is made by providing the thread with additional
sealing material such as, for example, PTFE tape (EN 837-2).

For further information on seals see WIKA data sheet AC 09.08 or under www.wika.com.

6.2 Making the electrical connection

■

The pressure transmitter must be earthed via the process connection.

■

Use the instrument with shielded cable.

■

Earth the shield on at least one end of the lead.

■

Only ever use a power source that ensures a safe electrical isolation of the operating voltage in
accordance with IEC/DIN EN 60204-1. In addition, observe the general requirements for PELV
circuits in accordance with IEC/DIN EN 60204-1.

Internal device error 1 (sensor unit non-synchronous)

The error message will be sent as soon as the synchronisation between the
instrument's two internal microprocessors is disturbed. Error correction through
reset.

Sensor bridge voltage outside permissible range

The sensor bridge voltage is only veried when turning on or after a reset. Error
correction through reset.

Pressure value more than 5 % over the end of the measuring range

The pressure is checked every 10 ms. The error message is sent for as long as
the pressure is outside the 5 % limit.

Pressure value more than 5 % under the start of the measuring range

The pressure is checked every 10 ms. The error message is sent for as long as
the pressure is outside the 5 % limit.

Temperature at the pressure sensor greater than 80 °C

The temperature is checked every 2.5 seconds. For as long as the temperature is
greater than 80 °C, the error message will be transmitted.

Internal device error 2 (internal communication error)

The error message will be sent as soon as there is a disruption of the internal data
exchange (sensor unit ⇔ evaluation electronics) detected. Error correction through
reset.

LED

The LED inside the instrument signals the following operating conditions:

■

LED o: No voltage supply or bus communication present

■

LED on: No bus communication

7. Maintenance and cleaning

7. Maintenance and cleaning

7.1 Maintenance

This pressure transmitter is maintenance-free.

GB

Repairs must only be carried out by the manufacturer.

7.2 Cleaning

CAUTION!

■

Before cleaning, correctly disconnect the pressure transmitter from the pressure supply,
switch it o and disconnect it from the voltage supply.

■

Clean the instrument with a moist cloth.

■

Wash or clean the dismounted instrument before returning it in order to protect personnel
and the environment from exposure to residual media.

■

Residual media in the dismounted instrument can result in a risk to persons, the
environment and equipment. Take sucient precautionary measures.

■

Do not use any pointed or hard objects for cleaning, as they may damage the diaphragm
of the process connection.

For information on returning the instrument see chapter 9.2 "Return".

CAUTION!

If deciencies cannot be eliminated by means of the measures listed above, shut down the
instrument immediately, and ensure that pressure and/or signal are no longer present, and
secure the instrument from being put back into operation inadvertently. In this case, contact
the manufacturer. If a return is needed, please follow the instructions given in chapter "9.2
