AUMA SAR 07.2 Manual

●
Safe STOP function: Safe STOP
- An operation command of standard controls (in directions OPEN or CLOSE)
will only be executed if an additional enable signal for the operation com-
mand is applied.
- If this is not the case, operation in directions OPEN or CLOSE is stopped
or even suspended (motor is switched off).
●
Safe ESD function combined with Safe STOP function
- Safe ESD function has a higher priority i.e. if both functions are activated,
the actuator is operated into the configured direction (OPEN/CLOSE).
The different configuration options of the safety functions are described in the
<Configuration (setting)/version> chapter.
4.3. Safe inputs and outputs
Safe inputs for Safe OPENING/CLOSING (Safe ESD function):
●
Safe ESDa
●
Safe ESDb
Safe inputs for safe stop (Safe STOP function):
●
Safe STOP OPEN
●
Safe STOP CLOSE
Safe outputs (indication that it might not be possible to perform the safety function:
●
SIL failure
●
SIL ready
For detailed information on safe inputs and outputs, refer to <Configuration
(setting)/version> chapter and <Installation> chapter.
4.4. Redundant system architecture
Besides the already described typical safety instrumented system including an
actuator, safety can be increased by integrating a second, redundant valve and
actuator with actuator controls in SIL version into the safety instrumented system.
The decision on the correct version depends on the entire system.With the redundant
system architecture shown below, actuator and actuator controls achieve SIL 3 in
accordance with IEC 61508.
