2. Mechanical Installation

2.1 Mounting and safety instructions

WARNING! Mount the device (pressure transmitter module) always in the state without pressure and apart from the display!

WARNING! This device may only be installed by qualified technical personnel who has read and understood the operating manual!

⚠️ WARNING! Do not use the display to tighten or solve to the mechanical connection of the pressure transmitter module!

!Handle this electronic precision measuring device carefully in packed as well as in unpacked condition!

!The device must not be subject to any changes or modifications.

!The device may not be thrown!

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

!Place the protective cap on the pressure port again immediately after disassembling.
!Handle the unprotected diaphragm very carefully - it is very sensitive and may be easily damaged.
!Do not use any force when installing the device to prevent damage of the device and the plant!
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 damage. This is especially important for very small pressure ranges as well as for devices with a pressure port made of plastic.
In hydraulic systems, position the device in such a way that the pressure port points upward (venting).
Provide a cooling line when using the device in steam lines.

• Carefully remove the pressure measuring device from the package and dispose of the package properly.
• Then go ahead as detailed in the specific instructions below.

2.3 Installation steps for DIN 3852

DO NOT USE ANY ADDITIONAL SEALING MATERIALS, LIKE YARN, HEMP OR TEFLON TAPE!

• Check to ensure the proper groove fitting of the o-ring and additionally to ensure no damage to the o-ring.
• Ensure that the sealing surface of the taking part is perfectly smooth and clean. (Rz 3.2)
• Screw the device into the corresponding thread by hand.
• If you have a device with a knurled ring, the transmitter has to be screwed in by hand only.
• Devices with a spanner flat have to be fully tightened with an open-end Devices (G1/4": approx. 5 Nm; G1/2": approx. 10 Nm).

- The indicated tightening torques must not be exceeded!

2.4 Installation steps for EN 837

• Use a suitable seal, corresponding to the medium and the pressure input (e. g. a cooper gasket).
• Ensure that the sealing surface of the taking part is perfectly smooth and clean. (Rz 6.3)
• Screw the device into the corresponding thread by hand.
• Tighten it with a wrench (for G1/4": approx. 20 Nm; for G1/2": approx. 50 Nm).

- The indicated tightening torques must not be exceeded!

2.5 Installation steps for NPT

• Use a suitable seal (e. g. a PTFE-strip).
• Screw the device into the corresponding thread by hand.

8. Operation

8.1 Operating and display elements

Fig. 3 Display and operating foil

The display of the measuring value as well as configuring the single parameters occurs menu-steered about a LC display capable of graphic arts. The single functions are regulated on the basis of three-front-sided arranged push buttons.

The menu system is closed, thereby one can "browse" forward as well as backward by the single setting menus to reach to the desired setting point.

• Left Button: if is a functional button and can be configured in the menu 6. Light-, Zero-, Reset- or Min- function can be assigned to the button. The configured function is active in the display mode. Hold the button during approx. 2 seconds to activate the function. In the operating mode you move in the menu system backward “<<” or you reduce the set value.
• Right Button: if is a functional button and can be configured in the menu 6. Light-, Zero-, Reset- or Max- function can be assigned to the button. . Hold the button during approx. 2 seconds to activate the function. In the operating mode you move in the menu system forward ">>" or you raise the set value.
• Menu-Button: by pressure of this button "menu" you reach in the operating mode; moreover, she serves for the choice of the single menu points "Edit" or in the confirmation the opposed worth "Next".

To the configuration of the single menu points the desired menu point is to be put with the help of the left button "<<" or right button ">>". Confirm this afterwards with the menu button "Edit" the menu point is marked and the configuration can begin.

To store an opposed value the menu button "Next" must be also pressed. To leave the menu press the menu button so often to the mark of the single menu point and choose with the left button "<<" or right button ">>" the menu 1 and press the menu button once more "Exit". The operating mode will also leave after approx. 1 min automatically.

Changes become first after activity of the menu button "Next" and after abandonment of the menu point effective. With the abandonment of the whole menu system the opposed parameters are checked once again in dependence to each other and concerning the characteristics of the device. With the configuration of the unity a conversion of the measuring area occurs in the new unity only after abandonment of the menu system. According to pressure area not all units can be also used if necessary.
