All DI can be set to PTC Card 1 [80]. However, only one DI must be set to this choice.
Take care that the DI that is set to [80] is not also connected as Themistor Resource (motor protection) in par. 1-93.
For further description, please refer to the VLT AutomationDrive FC 300 Programming Guide (MG.33.MX.YY).
5.1.2 Safe Stop Functionality
The desired Safe Stop functionality is specified in Par. 5-19. When a MCB 112 PTC Thermistor Card is mounted, one of the PTC choices should be selected
in order to get the full benefit from the alarm handling. Choices 4 and 5 are relevant when the MCB 112 is the only interrupt device using Safe Stop
whereas choices 6-9 are relevant when also other safety sensors are connected to Safe Stop. See section 4.1.1

.
Alarm - Drive coasts and Alarm must be manually reset (via Bus, Digital I/O, or by pressing [RESET]). Auto reset does not apply here.
Warning - Drive coasts but resumes operation when safe stop AND the DI from X44/ 10 are disabled.
Configuring a digital input in 5-1* makes it possible to give a warning/ alarm that specifies what enabled the safe stop.
When selecting warning instead of alarm, the drive opens up for Automatic Restart! See Installation of Safe Stop in combination with
MCB 112 in the Design Guide.
