5 Installation

5.1 Mounting dimensions

For dimensions, see the "Mechanical construction" section in the Technical Information.

5.2 Installation conditions

• Moisture must not penetrate the housing when mounting the device, establishing the electrical connection and during operation.

• For M12 plug made of metal: Do not remove the protection cap (only in IP69) of M12 plug connection until shortly before electrical connection.

• Do not clean or touch process isolating diaphragms with hard and/or pointed objects.

• Do not remove process isolating diaphragm protection until shortly before installation.

• Always tighten the cable entry firmly.

• Point the cable and connector downwards where possible to prevent moisture from entering (e.g. rain or condensation water).

• Protect housing against impact.

• For devices with gauge pressure sensor, the following applies:

NOTICE

If a heated device is cooled in the course of a cleaning process (by cold water, for example), a vacuum develops for a short time causing moisture to penetrate the sensor via the pressure compensation element (1).

Device could be destroyed!

In the event of this happening, mount the device in such a way that the pressure

‣

compensation element (1) is pointing downwards at an angle or to the side, if possible.

A0022252

5.3 Influence of the installation position

Any orientation is possible. However, the orientation may cause a zero point shift i.e. the measured value does not show zero when the vessel is empty or partially full.

IO-Link information

IO-Link is a point-to-point connection for communication between the measuring device and an IO-Link master. The measuring device features an IO-Link communication interface type 2 with a second IO function on pin 4. This requires an IO-Link-compatible assembly (IO-Link master) for operation. The IO-Link communication interface enables direct access to the process and diagnostic data. It also provides the option of configuring the measuring device while in operation.

Physical layer, the measuring device supports the following features:

• IO-Link specification: version 1.1

• IO-Link Smart Sensor Profile 2nd Edition (supports minimum scope of IdentClass)

• SIO mode: Yes

• Speed: COM2; 38.4 kBaud

• Minimum cycle time: 2.5 msec.

8.1 Process data

The measuring device has a current output and a switch output. The status of the switch output is transmitted in the form of process data via IO-Link.

• In the SIO mode, switch output 1 is switched at pin 4 of the M12 plug. In the IO-Link communication mode, this pin is reserved exclusively for communication.

• The current output at pin 2 of the M12 plug is always active or can be optionally deactivated via IO-Link.

• The device's process data are transmitted cyclically in 32-bit chunks.

Bit 0 (LSB) 1 ... 28 29 (MSB) 30 31

Measuring device Pressure value OU1 res.

Bit 31 is reserved. Bit 30 provides the status of the switch output.

Here, 1 or DC 24 V corresponds to the logical "closed" state on the switch output. The remaining 30 bits contain the analog raw measured value of the device. This value has yet to be scaled by the target system to the nominal operating range of the existing measuring device.
