3 Sensor element
A temperature sensor on the respective sensor element for pressure records the current process temperature. The temperature value is output via Bluetooth, for example.
Relative pressure : the measuring cell is open to the atmosphere.
The ambient pressure is detected in the measuring cell and compensated. It thus has no influence on the measured value.
Absolute pressure : the measuring cell contains vacuum and is encapsulated. The ambient pressure is not compensated and does hence influence the measured value.
The measuring system is completely welded and thus sealed against the process.

4.1 General instructions
The instrument is suitable for standard and extended ambient conditions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used indoors as well as outdoors.
Note:
For safety reasons, the instrument must only be operated within the permissible process conditions. You can find detailed information on the process conditions in chapter " Technical data " of the operating instructions or on the type label.
Hence make sure before mounting that all parts of the instrument exposed to the process are suitable for the existing process conditions.
These are mainly:
• Active measuring component
Process fitting
Process seal
Process conditions in particular are:
• Process pressure
Process temperature
Chemical properties of the medium
• Abrasion and mechanical influences
The permissible process pressure range is specified by "MWP" (Maximum Working Pressure) on the type label, see chapter " Structure ".
The MWP takes the element of the measuring cell and processing fitting combination with the weakest pressure into consideration and may applied permanently. The specification refers to a reference temperature of +20 °C (+68 °F). It also applies when a measuring cell with a higher measuring range than the permissible pressure range of the process fitting is installed order-related.
In addition, a temperature derating of the process fitting, e. g. with flanges, can limit the permissible process pressure range according to the respective standard.
Note:
In order to prevent damage to the device, a test pressure may only exceed the specified MWP briefly by 1.5 times at reference temperature. The pressure stage of the process fitting as well as the overload resistance of the measuring cell are taken into consideration here
(see chapter " Technical Data ").

6 Access protection
6 Access protection
6.1 Bluetooth radio interface
Devices with a Bluetooth radio interface are protected against unwanted access from outside. This means that only authorized persons can receive measured and status values and change device settings via this interface.
A Bluetooth access code is required to establish Bluetooth communication via the adjustment tool (smartphone/tablet/notebook).
This code must be entered once when Bluetooth communication is established for the first time in the adjustment tool. It is then stored in the adjustment tool and does not have to be entered again.
The Bluetooth access code is individual for each device. It is printed on the device housing with Bluetooth. In addition, it is supplied with the device in the information sheet " PINs and Codes " In addition, the
Bluetooth access code can be read out via the display and adjustment unit, depending on the device version.
The Bluetooth access code can be changed by the user after the first connection is established. If the Bluetooth access code is entered incorrectly, the new entry is only possible after a waiting period has elapsed. The waiting time increases with each further incorrect entry.
The emergency Bluetooth access code enables Bluetooth communication to be established in the event that the Bluetooth access code is no longer known. It can't be changed. The emergency Bluetooth access code can be found in information sheet " Access protection ".
If this document is lost, the emergency Bluetooth access code can be retrieved from your personal contact person after legitimation.
The storage and transmission of Bluetooth access codes is always encrypted (SHA 256 algorithm).
6.2 Protection of the parameterization
The settings (parameters) of the device can be protected against unwanted changes. The parameter protection is deactivated on delivery, all settings can be made.
To protect the parameterization, the device can be locked by the user with the aid of a freely selectable device code. The settings (parameters) can then only be read out, but not changed. The device code is also stored in the adjustment tool. However, unlike the Bluetooth access code, it must be re-entered for each unlock. When using the adjustment app or DTM, the stored device code is then suggested to the user for unlocking.
The emergency device code allows unlocking the device in case the device code is no longer known. It can't be changed. The emergency device code can also be found on the supplied information sheet " Access protection ". If this document is lost, the emergency device code can be retrieved from your personal contact person after legitimation.

10.1 Maintenance
In some applications, product buildup on the 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.
The cleaning helps that the type label and markings on the instrument are visible.
Take note of the following:
• Use only cleaning agents which do not corrode the housings, type
• label and seals
Use only cleaning methods corresponding to the housing protection rating

Causes of malfunction
10.2 Rectify faults
The operator of the system is responsible for taking suitable measures to rectify faults.
The device offers maximum reliability. Nevertheless, faults can occur during operation. These may be caused by the following, e.g.:
• Sensor
Process
• Voltage supply
Signal processing
Fault rectification
Reaction after fault rectification
24 hour service hotline
The first measures are:
• Evaluation of fault messages
Checking the output signal
Treatment of measurement errors
A smartphone/tablet with the adjustment app or a PC/notebook with the software PACTware and the suitable DTM offer you further comprehensive diagnostic possibilities. In many cases, the causes can be determined in this way and the faults eliminated.
Depending on the reason for the fault and the measures taken, the steps described in chapter " Setup " must be carried out again or must be checked for plausibility and completeness.
Should these measures not be successful, please call in urgent cases the VEGA service hotline under the phone no. +49 1805 858550 .
The hotline is also available outside normal working hours, seven days a week around the clock.
Since we offer this service worldwide, the support is provided in
English. The service itself is free of charge, the only costs involved are the normal call charges.
