4 Mounting 4 Mounting 4.1 General instructions Suitability for process conditions Make sure that all parts of the instrument in contact with the measured product, especially the sensor element, process seal and process fitting, are suitable for the existing process conditions such as process pressure, process temperature as well as the chemical properties of the medium. You can find the specifications in chapter "Technical data" in the or on the type label.
4 Mounting Ventilation and pressure compensation The ventilation of the measuring cell is realised by a filter element in the socket of the electronics housing. The ventilation of the electronics housing is realised via an additional filter element around the cable glands.2) 2 1 Fig.
4 Mounting Oxygen applications Danger: Instruments in the version "Oil and grease free for oxygen" should be unpacked just before mounting. After the protective cover of the process fitting has been removed, the label "O₂" on the process fitting is visible. Contamination by oil, grease and dirt should be avoided. Danger of explosion! 4.2 Mounting instructions Mounting position IPT-1* functions in any installation position. It is mounted according to the same directives as a manometer (DIN EN 839-2).
5 Connecting to power supply 5 Connecting to power supply 5.1 Preparing the connection Note safety instructions Always keep in mind the following safety instructions: l l Connect only in the complete absence of line voltage If overvoltage surges are expected, overvoltage arresters should be installed Take note of safety instructions for Ex applications In hazardous areas you should take note of the appropriate regulations, conformity and type approval certificates of the sensors and power supply units.
5 Connecting to power supply Select connection cable for Ex applications Take note of the corresponding installation regulations for Ex applications. In particular, make sure that no potential equalisation currents flow over the cable screen. In case of grounding on both sides this can be achieved by the use of a capacitor or a separate potential equalisation. 5.

You will find a detailed description in the operating instructions manual "Indicating and adjustment module" or in the online help of PACTware or DTM.
6 Set up with the indicating and adjustment module To select the adjustment unit (in the example switching over from bar to mbar) you have to proceed as follows:4) 1 ▶ 2 Push the [OK] button in the measured value display, the menu overview is displayed. Basic adjustment Display Diagnostics Service Info Confirm the menu "Basic adjustment" with [OK], the menu item "Unit" will be displayed.
6 Set up with the indicating and adjustment module Unit of measurement Density 0001000 kg/dm³ 6 Enter the requested density value with [->] and [+], confirm with [OK] and move to position correction with [->]. The adjustment unit is hence switched over from bar to m. Proceed as follows to select the temperature unit:5) à Activate the selection with [OK] and select "Temperature unit with [->]. à Activate the selection with [OK] and select the requested unit with [->] (e.g. °F). à Confirm with [OK].
6 Set up with the indicating and adjustment module 5 Confirm with [+] and move to max. adjustment with [->]. The min. adjustment is finished. Information: For an adjustment with filling, you simply enter the displayed actual measured value. If the adjustment ranges are exceeded, the message "Outside parameter limits" appears. The editing procedure can be aborted with [ESC] or the displayed limit value can be accepted with [OK]. Carrying out max.
6 Set up with the indicating and adjustment module The position correction compensates the influence of the mounting position or static pressure on the measurement. It does not influence the adjustment values. In the menu items "zero" and "span" you determine the span of the sensor, the span corresponds to the end value.

8 Maintenance and fault rectification 8 Maintenance and fault rectification 8.1 Maintenance, cleaning When used in the correct way, no special maintenance is required in normal operation. In some applications, product buildup on the sensor diaphragm can influence the measuring result. Depending on the sensor and application, take precautions to ensure that heavy buildup, and especially a hardening thereof, is avoided. If necessary, the transmitter has to be cleaned.
8 Maintenance and fault rectification l No power supply à Check cables for breaks; repair if necessary l Operating voltage too low or load resistance too high à Check, adapt if necessary ? Current signal greater than 22 mA or less than 3.6 mA l electronics module or measuring cell defective à Exchange instrument or return instrument for repair In Ex applications, the regulations for the wiring of intrinsically safe circuits must be observed.
