Safe Stop Commissioning Test - Danfoss VLT AutomationDrive FC 300 Design Manual

FC 300 Design Guide
Illustration 3.7: Illustration of the essential aspects for installing a combination of a Safe Stop application
and a MCB112 application. The diagram shows a Restart input for the external Safety Device. This means
that in this installation parameter 5-19 might be set to value [7] or [8].
Parameter settings for Safe Stop in com-
bination with MCB112
If MCB112 is connected, then additional settings are possible for parameter 5-19: [1] (default)
and [3] are still available, but should not be set. They must be set if only Safe Stop is used. If [1]
or [3] are chosen and MCB112 is triggered, then the FC300 will react with an alarm "Dangerous
Failure [A72]" and stop the drive safely, without Automatic Restart. [4] and [5] are available then,
but should not be used. They must be used if only MCB112 is connected, and no other safety-
related sensor. If [4] or [5] are chosen and Safe Stop is activated, then the FC300 will react with
an alarm "Dangerous Failure [A72]" and stop the drive safely, without Automatic Restart.
Choices [6], [7], [8] or [9] must be used for combination of Safe Stop and MCB112. IMPORTANT!
Choices [7] or [8] set Safe Stop to Automatic Restart.
This is only allowed in one of the two following situations:

3.11.4. Safe Stop Commissioning Test

After installation and before first operation, perform a commissioning test of an installation or
application making use of FC 300 Safe Stop.
Moreover, perform the test after each modification of the installation or application, which the FC
300 Safe Stop is part of.
The Unintended Restart Prevention is implemented by other parts of the Safe Stop in-
stallation.
A presence in the dangerous zone can be physically excluded when Safe Stop is not
activated. In particular, the following paragraphs of standards under the EU Machinery
Directive must be observed: 5.2.1, 5.2.2, and 5.2.3. of EN954-1:1996 (or ISO
13849-1:2006), 4.11.3 and 4.11.4 of EN292-2 (ISO 12100-2:2003).
NB!
A passed commissioning test is mandatory for fulfilment of Safety Category 3 by
such an installation or application.
