1. Important details for your information

Read these operating instructions before installing and starting the pressure transmitter. Keep the operating instructions in a place that is accessible to all users at any time. The following installation and operating instructions have been compiled by us with great care but it is not feasible to take all possible applications into consideration. These installation and operation instructions should meet the needs of most pressure measurement applications. If questions remain regarding a specific application, you can obtain further information:

With special model number, e.g. SL-10000, please note specifications in the delivery note. If the serial number and/or the 2D code on the hexagon gets illegible (e.g. by mechanical damage or repainting), the retraceability of the instrument is not possible any more.

WIKA pressure transmitters are carefully designed and manufactured using state-of-the-art technology. Every component undergoes strict quality and environmental inspection before assembly and each instrument is fully tested prior to shipment. Our environmental management system is certified to DIN EN ISO 14001.

Use of the product in accordance with the intended use SL-1:

Use the pressure transmitter to transform the pressure into an electrical signal.

Knowledge required

Install and start the pressure transmitter only if you are familiar with the relevant regulations and directives of your country and if you have the qualification required. You have to be acquainted with the rules and regulations on measurement and control technology and electric circuits. Depending on the operating conditions of your application you have to have the corresponding knowledge, e.g. of aggressive media.

2. A quick overview for you

If you want to get a quick overview, read Chapters 3, 5, 7 and 11. There you will get some short safety instructions and important information on your product and its starting. Read

these chapters in any case.

Notice, important information, malfunction.

The product complies with the applicable European directives.

4. Function

The pressure prevailing within the application is transformed into a standardised electrical signal through the deflection of the diaphragm, which acts on the sensor element with the power supply fed to the transmitter. This electric signal changes in proportion to the pressure and can be evaluated correspondingly.

Check the scope of supply:

 Completely assembled pressure transmitters  Inspect the pressure transmitter for possible damage during transportation. Should

there be any obvious damage, inform the transport company and WIKA without delay.

 Keep the packaging, as it offers optimal protection during transportation (e.g. chan-

ging installation location, shipment for repair).

 Ensure that the pressure connection thread and the connection contacts will not be

damaged.

7. Starting, operation

Diaphragm test for your safety

It is necessary that before starting the pressure transmitter you test the diaphragm, as this is a safety-relevant component.

 Use the pressure transmitter only if the diaphragm is undamaged.

Warning

 Use the pressure transmitter only if it is in a faultless condition as far as the

safety-relevant features are concerned.

7. Starting, operation

 Screw in or unscrew the instrument only via the flats using a suitable tool and the

prescribed torque. The appropriate torque depends on the dimension of the pressure connection and on the sealing element used (form/material). Do not use the case as

working surface for screwing in or unscrewing the instrument.

 When screwing the transmitter in, ensure that the threads are not jammed.  For tapped holes and welding sockets please see Technical Information IN 00.14 for

 Please refer to our data sheet “Pressure gauge sealing washers AC 09.08” in WIKA’s

product catalog Pressure and Temperature Measurement or our website www.wika.de for details about sealing washers.

 When mounting the instrument, ensure that the sealing faces of the instrument and

the measuring point are clean and undamaged.

WIKA Operating instructions/Betriebsanleitung/Mode d'emploi SL-1

Electrical connection

 Connect the instrument to earth via the pressure connection.  This equipment of protection class 3 is designed for connection to safety low voltages

that are separated from the mains voltage or from a voltage greater than AC 50 V or

DC 120 V. It is preferred to connect it to SELV or PELV electric circuits; alternatively, a

safety measure from HD 60346-4-41 (DIN VDE 0100-410) is recommended.

Alternative for North America: The connection may also be made to „Class 2 Circuits“

or „Class 2 Power Units“ according to CEC (Canadian Electrical Code) or NEC (Nati-

onal Electrical Code).

 Operate the pressure transmitter with a shielded cable and earth the shield at least

on one side of the cable, if the cable is longer than 30 m or if it is run outside of the

building.

 Ingress protection per IEC 60529 (The ingress protection classes specified only apply

while the pressure transmitter is connected with female connectors that provide the

corresponding ingress protection).

 Ensure that the cable diameter you select fits to the cable gland of the connector.

Ensure that the cable gland of the mounted connector is positioned correctly and

that the sealings are available and undamaged. Tighten the threaded connection and

check the correct position of the sealings in order to ensure the ingress protection.

 Please make sure that the ends of cables with flying leads do not allow any ingress of

moisture.

When designing your plant, take into account that the stated values (e.g.burst pressure, over pressure safety) apply depending on the material, thread and sealing element used.

Functional test

The output signal must be proportional to the pressure. If not, this might point to a damage of the diaphragm. In that case refer to chapter 10 „Troubleshooting“.

 Open pressure connections only after the system is without pressure!

Warning

 Observe the ambient and working conditions outlined in section 7 „Technical

data".

 Please make sure that the pressure transmitter is only used within the over-

load threshold limit at all times! When touching the pressure transmitter, keep in mind that the surfaces of

the instrument components might get hot during operation.

8. Adjustment of zero point / span (only for pressure transmitter with clamping nut)

We do not recommend to adjust the span potentiometer. It is used for adjustment ex factory and should not be adjusted by you unless you have adequate calibration equipment at your disposal (at least three times more accurate than the instrument being tested).

 Make sure wires are not cut or pinche

during disassembly and reassembly of the connector.

 Remove the female connector. Open

the pressure transmitter by detaching the clamping nut (see Fig. A ). Carefully remove the male connector from the case.

 Adjust the zero point (Z) (see Fig. B ) by

generating the lower limit of the pressure range.

 Adjust the span (S) by generating the

higher limit of the pressure range.

 Check the zero point.  If the zero point is incorrect, repeat

procedure as required.

 Reassemble the instrument carefully.  Make sure all sealings and o-rings are

not damaged and correctly installed to

assure the rated moisture ingress protec-

tion.
