5 Setup
5.1 General information
Take note of the mounting and installation instructions in the operating
instructions manual.
When locking the adjustment, the instrument checks the data of the
measurement loop and decides on the basis of the evaluation results
if it is necessary to check the level.
Hence the following actions must be carried out at the time of every
startup:
•
Unlock adjustment
•
if necessary, change parameters
•
Lock adjustment and verify modified parameters, if necessary
5.2 Instrument parameter adjustment
The following adjustment units are permitted for parameterization of
the safety function:
•
Display and adjustment module
•
The DTM suitable for VEGAFLEX 80 in conjunction with an
adjustment software according to the FDT/DTM standard, e. g.
PACTware
•
The device description EDD suitable for VEGAFLEX 80
The parameter adjustment is described in the operating instructions
manual.
The documentation of the device settings is only possible with the full
version of the DTM Collection.
For protection against unwanted or unauthorzed adjustment, the set
parameters must be protected against unauthorized access. For this
reason, the instrument is shipped in locked condition. The PIN in
delivery status is "0000".
The default values of the parameters are listed in the operating in-
structions. When shipped with customer-specific parameter settings,
the instrument is accompanied by a list of the values differing from the
default values.
By means of the serial number this list can also be downloaded at
www.vega.com /VEGA Tools/serial number search .
To avoid or detect possible errors during parameter adjustment for
unsafe operating environments, a verification procedure is used that
allows the safety-relevant parameters to be checked.
Parameter adjustment proceeds according to the following steps:
•
Unlock adjustment
•
Change parameters
•
Lock adjustment and verify modified parameters
The exact process is described in the operating instructions.
