FC 300 Design Guide
The Safe Stop function can be set to an Automatic Restart behaviour by setting the value of
parameter 5-19 from default value [1] to value [3]. If a MCB112 Option is connected to the drive,
then Automatic Restart Behaviour is set by values [7] and [8].
Automatic Restart means that Safe Stop is terminated, and normal operation is resumed, as soon
as the 24Vdc are reapplied to Terminal 37, no Reset signal is required.
IMPORTANT! Automatic Restart Behaviour is only allowed in one of the two situations:
1.
2.
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).
