Vega VEGAPULS 6X - First Setup

8 Functional safety (SIL)
VEGAPULS 6X • Two-wire 4 … 20 mA/HART
66190-EN-221107
The parameter settings of the measuring point must be documented.
A list of the safety-relevant parameters can be stored and printed ad-
ditionally by the PACTware/DTM.
Information:
Whenshippedwithaspecicparameteradjustment,theinstruments
are accompanied by a list with the values deviating from the default
setting.
For each parameter change, the device must be unlocked via the
device code (see chapter " Parameter adjustment, setup steps - Lock
adjustment"). The device status is indicated in the respective adjust-
ment tool by the symbol of an unlocked or locked padlock.
Warning:
If adjustment is enabled, the safety function must be considered
as unreliable. This applies until the parameterisation is terminated
correctly. If necessary, other measures must be taken to maintain the
safety function.
All parameters changed by the operator are automatically stored
temporarilysothattheycanbeveriedinthenextstep.
Aftersetup,themodiedparametersmustbeveried(conrmthe
correctnessoftheparameters).Todothis,yoursthavetoenterthe
device code. Here the adjustment is locked automatically. Then you
carryoutacomparisonoftwocharacterstrings.Youmustconrmthat
the character strings are identical. This is used to check the character
presentation.
Thenyouconrmthattheserialnumberofyourinstrumenthasbeen
carried over correctly. This is used to check device communication.
Then,allmodiedparametersthathavetobeconrmedarelisted.
After this process is terminated, the safety function is again ensured.
Warning:
If the described process was not carried out completely or correctly
(e.g. due to interruption or voltage loss), the instrument remains in an
unlocked, and thus unsafe, status.
Warning:
When the device is reset to default settings, all of the safety-relevant
parameters are reset. Therefore, these must be checked or read-
justed afterwards.
8.5 First setup
8.5.1 Overview
The initial setup serves to check the device version and the current
parameters under the existing measurement conditions. This deter-
mineswhetherthisconstellationissuitableforprovidingqualied
measurement data for safety-related instrumentation.
