Oxygen applications 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.
4 Mounting Sealing/Screwing in Use the seal corresponding to the instrument: l Process fitting GD: Tesnit seal in front of the thread - or Seal the thread with teflon, hemp or a similar resistant seal material: l Process fitting GN à Screw IPT-1* into the welded socket. Tighten the hexagon on the process fitting with a suitable wrench. Wrench size, see chapter "Dimensional drawings".
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.

6 Set up with the indicating and adjustment module 6.4 Setup procedure Level or process pressure measurement IPT-1* can be used for level as well as for process pressure measurement. Default setting is level measurement. The mode can be changed in the adjustment menu. Depending on the application only the respective subchapter "Level or process pressure measurement" is of importance. There, you find the individual adjustment steps.
6 Set up with the indicating and adjustment module ▶ 2 Basic adjustment Display Diagnostics Service Info Confirm the menu "Basic adjustment" with [OK], the menu item "Unit" will be displayed. Unit Unit of measurement bar▼ Temperature unit °C▼ 3 Activate the selection with [OK] and select "Units of measurement with [->]. 4 Activate the selection with [OK] and select the requested unit with [->] (in the example mbar). 5 Confirm with [OK] and move to position correction with [->].
6 Set up with the indicating and adjustment module The adjustment unit is thus switched over from bar to m. Proceed as follows to select the temperature unit:4) 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]. The temperature unit is hence switched over from °C to °F.
6 Set up with the indicating and adjustment module 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. adjustment Proceed as follows: 1 Edit the % value in the menu item "Max. adjustment" with [OK]. Max. adjustment +100.0 % = +1000.0 mbar 0000.
6 Set up with the indicating and adjustment module In the menu items "zero" and "span" you determine the span of the sensor, the span corresponds to the end value. Information: The steps 1, 3 and 4 are not necessary for instruments which are already preset according to customer specifications! You can find the data on the type label on the instrument or in the menu items of the zero/span adjustment. The indicating and adjustment module enables the adjustmetn without filling or pressure.

If IPT-1* is equipped with an indicating and adjustment module, the most important data can be read out of the sensor into indicating and adjustment module.
7 Maintenance and fault rectification 7 Maintenance and fault rectification 7.1 Maintenance, cleaning When the instrument is used properly, 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.
7 Maintenance and fault rectification ? 4 … 20 mA signal missing l Connection to voltage supply wrong à Check connection according to chapter "Connection steps" and if necessary, correct according to chapter "Wiring plan" 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.
