WARNING!
GB Before installation, commissioning and operation, ensure that the appropriate pressure transmitter has been selected in terms of measuring range, design and specific 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 "Specifications". ■■ 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.
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 specifications contained in these operating instructions must be observed.Improper handling or operation of the instrument outside of its technical specifications requires the instrument to be taken out of service immediately and inspected by an authorisedWIKA service engineer.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.

2.2Personnel qualification
WARNING!
Risk of injury if qualification is insufficient! GB
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 qualifications 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-specific 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, flammable 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 sufficient precautionary measures.

4.Design and function
4.1 Description |
|
|
GB |
||
D-10-7: Process connection with internal diaphragm. |
||
D-11-7: Process connection with flush diaphragm for highly viscous or crystallising media. |
|
By means of a sensor element and by applying power, the prevailing pressure is converted into an amplified standardised electrical signal via the deformation of a diaphragm.This electrical signal varies in proportion to the pressure and can be evaluated accordingly.
4.2 Scope of delivery
Cross-check the scope of delivery with the delivery note.
2478159.05 12/2011 GB/D/F/E
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
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.

6.Commissioning, operation
|
CAUTION! |
|
GB |
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 fluid is indicative of damage. |
|
■■ |
Only use the pressure transmitter if it is in perfect condition with respect to safety. |
6.1 Making the mechanical connection
Required tool:Open-ended spanner (spanner width 27 or 41), screwdriver
■■ 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 flats.
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, seeTechnical Information IN 00.14 at www.wika.com.

Correct sealing of the process connections with parallel threads at the sealing face must be made using suitable flat gaskets, sealing rings orWIKA profile 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 seeWIKA 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.

6.4 Services
Byte 6 "Service request" contains the identifier of the service performed (see table "Overview of services"). Bytes 7 and 8 "Service response 1" and "Service Response 2" contains the respective response to a service.If there is no service request, bytes 6 ...8 have a value of 0x00.
The request for the services is carried out via 3 byte output data (from the master).The response is in the input data (byte 6 ...8) in the send message.

Error detection
Byte 4 (error status) and byte 5 (error code) contain the error messages. The error status shows whether there is an error present.If there is an error, this can be read via the error code (see example).
Example
Error code 42hex corresponds to binary 01000010, i.e.bit 1 and 6 are set.Error correction through reset.
The encoding should be read from the following diagram.

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 verified 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.
Res.
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 off:No voltage supply or bus communication present
■■ LED on:No bus communication

7.Maintenance and cleaning
7.Maintenance and cleaning
7.1 Maintenance
GB This pressure transmitter is maintenance-free. 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 off 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 sufficient 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".
