---|---

WARNING| Danger of death from improper installation

• This device may only be installed by qualified technical personnel who has read and understood the operating manual!
• Do not use the display to tighten or solve to the mechanical connection of the pressure transmitter module!

NOTE – Operation of the display AX16-DM01 with the EC-Type Examination certificate IBExU12ATEX1108 X is permitted only in combination with the accompanying pressure transmitter with the EC-Type Examination certificate IBExU10ATEX 1026U!

NOTE – If both equipments have not been used in the scheduled combination (display AX16-DM01 / pressure transmitter with certificate IBExU10 ATEX 1026 U), then the complete system has to be put immediately out of operation!

A potentially damage of one or both devices could have been occurred! The device(s) consequently lose the IS-certification when using not for intended purpose!

NOTE – Handle the unprotected diaphragm very carefully – it is very sensitive and may be easily damaged.

NOTE – To avoid damaging the diaphragm, remove packaging and protective cap only directly before starting up the device. A delivered protective cap must be stored!

NOTE – Place the protective cap on the pressure port again immediately after disassembling.

NOTE – Do not use any force when installing the device to prevent damage of the device and the plant!

NOTE – Never use the display as a mounting / dismounting aid, otherwise the device or the plug-in connections will be irreparably damaged. For mounting or dismounting the device, only use the hexagon on the pressure port.

NOTE – Take note that no inadmissibly high mechanical stresses occur at the pressure port as a result of the installation, since this may cause a shifting of the characteristic curve or to the demage.

NOTE – The permissible tightening torque depends on the conditions on site (material and geometry of the mounting point). The specified tightening torques for the device must not be exceeded!

NOTE – In hydraulic systems, position the device in such a way that the pressure port points upward (venting).

NOTE – Provide a cooling line when using the device in steam lines.

NOTE – If the device is installed with the pressure port pointing upwards, ensure that no liquid drains off on the device. This could result in humidity and dirt blocking the gauge reference in the housing, and could lead to malfunctions. If necessary, dust and dirt must be removed from the edge of the screwed joint of the electrical connection.

NOTES – for mounting outdoors or in a moist environment:

• Please note that your application does not show a dew point, which causes condensation and can damage the device. There are specially protected devices for these operating conditions. Please contact us in such case.
• Connect the device electrically straightaway after mounting or prevent moisture penetration, e.g. by a suitable protective cap. (The protection rating specified on the data sheet applies to the connected device.)
• Select the mounting position such that splashed and condensed water can drain off. Stationary liquid on sealing surfaces must be excluded!
• Mount the device such that it is protected from direct solar radiation. In the most unfavourable case, direct solar radiation leads to the exceeding of the permissible operating temperature. This must be excluded if the device is used in any explosion-hazardous area!
• A device with gauge reference in the housing (small hole next to the electrical connection) must be mounted such that the gauge reference is protected against dirt and humidity. If the transducer is exposed to liquid admission, the gauge reference will be blocked, and the equalization of air pressure will be prevented. In this condition, a precise measurement is impossible and damage to the transducer may occur.

Conditions for oxygen applications

Make sure that your device was ordered for oxygen applications and delivered accordingly. (see type plate – order code ends with the numbers “007”) Unpack the device directly prior to the installation.

Skin contact during unpacking and installation must be avoided to prevent fatty residues remaining on the device. Wear safety gloves!
