Single-channel switching relay or semi-conductor output with
external switching amplifier and testing
When using external switching amplifiers or downstream electro-mechanical,
pneumatic or hydraulic components, the setup for testing the complete chain
and a message/warning feature for detected faults is required in order to
achieve PL c or higher.
Positively guided auxiliary contacts are especially needed for electro-
mechanical devices and message contacts for the valve position are required
for hydraulic or pneumatic components.
The message/warning device must ensure that the operator recognizes the
dangerous situation immediately.
The achievable PL is mainly depending on the test rate, PL d acc. to nach EN
ISO 13849-1 can maximally be achieved!

SAFETY
NOTE
•
Only conditionally recommended for safety applications! In this context
see also the notes in EN ISO 13849-1 concerning the application and
the required fault exclusions.
•
For category 2 a test rate >= 100 * request rate is required.
•
If a hazardous situation is detected during a test of the safety function,
suitable control measures must be initiated. For PL d, a safe state must
be initiated which may not be lifted until the fault has been eliminated.
For PL up to and including PL c, it is also possible to indicate a fault by
means of a warning or signalling device if a safe state cannot be
initiated.
