DESCRIPTION DE L'APPAREIL
2
The following equipment is permitted for parameterization of the safety function:
• The integrated display and operating unit for on-site operation
• The DTM suitable for the device in conjunction with frame software according to the FDT/DTM
standard, e.g. PACTware
To avoid possible errors during parameter adjustment in unsafe operating environments, a
verification procedure is used that allows parameterization errors to be reliably detected. To do
this, safety-relevant parameters must be verified after they have been stored in the device. In
addition, to protect against unwanted or unauthorised adjustment, the device is locked in normal
operating state against any parameter changes. This concept applies both to the operation at the
device as well as to PACTware with DTM.
For protection against unwanted or unauthorised adjustment, the set parameters must be
protected against unauthorised access. For this reason, the device is shipped in locked
condition. The PIN in delivery status is "0000". When shipped with specific parameter settings,
the device is accompanied by a list of the values differing from the basic settings.
All safety-relevant parameters must be verified following a change. The parameter settings of
the measuring point must be documented. A list of all of the safety-relevant parameters present
upon delivery can be found in the "Reset" chapter. à la page 63. In addition, a list of the safety-
relevant parameters can be saved and printed using PACTware/DTM.
The device must be unlocked using a PIN to make any changes to parameters. The status of the
device is indicated in the display with the symbol of a locked or unlocked padlock. The PIN in
delivery status is "0000".
Any parameter changes made by the operator are automatically saved for verification in the next
step.
Following start-up, you must verify the modified parameters (confirm the correctness of the
parameters). To do this you must first enter the PIN. Adjustment is then automatically locked.
Then you must compare two strings. You must confirm that both strings are identical. This is to
check the string display. Then confirm that the serial number of your device has been saved
correctly. This checks for proper device communication. Then all of the modified parameters are
listed and each must be confirmed. Upon completion of this procedure, the safety function is
once again guaranteed.
