Installation; Preparing For Installation - ABB 364G Series Manual

Installation

Read carefully these installation instructions before proceeding. Failure to observe the warnings and
instructions may cause a malfunction or personal hazard.
As already specified in t he Safety Notes th e installation must only be carried out by suitably trained
personnel and in accordance with the information given. Any deviation from these instructions, will transfer
the complete liability to the user.
It is not recommended to install the transmitter and leave the cover open or the electical input without the
appropriate plugs. Water penetration can damage the electrical circuit.

Preparing for installation

Before installing the pressure transmitter, check whether the model meets the measurement and safety
requirements of the measuring point. This applies for:
• Measuring range
• Overpressure stability
• Temperature
• Explosion protection
• Operating voltage
The materials must be checked to ensure compatibility with regard to their resistance to the media.
This applies for:
• Gaskets
• Process connections, etc.
In addition, the relevant directives, regulations, standards and accident prevention regulations
must be observed. (e.g., VDE/VDI 3512, DIN 19210, VBG, Elex V, etc.).
Measurement accuracy is largely de pendent on correct installation of the pre ssure transmitter and, if
applicable, the related m easuring tube. The m easuring setup should be as free as possible of critical
ambient conditions such as major temperature variations, vibration or shock.
Note
If unfavorable ambient condition s cannot be avo ided owing to rea sons related to bu ilding structure,
measuring requirements or other reasons, this may influence the measurement quality.
If a pressure sensor with capillary tube is installed, observe also the related data sheets.
Pressure transmitter
The transmitter can be connected directly to the shu t-off valve. There is also a mounting bracket for wall or
pipe installation (2" pipe) available as an accessory.
The pressure transmitter should be installed so that the di splay and control unit are a ccessible during
installation and connection, as well as retrofitting.
The transmitter should be installed preferably in a vertical position to avoid subsequent zero shift corrections.
Note
In case of an oblique installation and depending on the measuring range, the fill fluid exert s a hydrostatic
pressure on the measuring diaphragm, resulting in a zero shift. The zero point must then be adjusted.
In general, the pressure transmitters can be used in any mounting position. It is installed according to t he
same guidelines as a manometer
