[1] Actuator
Connect the actuator between F-DO._P and the GND reference potential.
The actuator input need not be isolated.
The sourcing output connection variant is suitable for applications up to SIL 3 pursuant
to IEC 61508 and Performance Level d pursuant to EN ISO 13849-1.
The MOVISAFE
®
CS..A safety card detects the following faults in the external cabling
when the output is switched on or off:
•
Short circuit between sourcing output and a supply voltage that lies within the
range 15 - 30 V and has the same ground potential as the assembly.
The MOVISAFE
®
CS..A safety card also detects the following faults when the output is
activated:
•
Short circuit between different sourcing outputs
•
Short circuit between the P output and the reference potential 0 V
•
Overload at every output
•
Wire break F-DO., if activated)
WARNING
In case of a short circuit between the sourcing output and a 24 V supply voltage, the
MOVISAFE
®
CS..A safety card can no longer switch off the actuator nor otherwise
switch over to a safe state.
The line diagnostics function can detect the fault. However, the MOVISAFE
®
CS..A
safety card cannot switch over to the safe state as there is no redundant switch-off
channel in this connection variant.
Severe or fatal injuries.
•
Route the cables in such a way that no short circuit between the sourcing output
and a +24 V supply voltage is possible.
•
Make sure that an additional redundant switch-off channel exists for the actuator
(e.g., by using a second sourcing output).
INFORMATION
SEW-EURODRIVE recommends the sourcing/sinking output or using 2 parallel,
sourcing outputs, if possible.
For safe outputs, refer also to details contained in the chapter "Technical data".
