AUMA SA Series - Signal Via Fieldbus of Standard Controls; Status Signals Via Output Contacts (Digital Outputs) of Standard Controls

Impact on safety function
→ Remedy
Description/
cause of fault
Indication on display
Standard controls
●
The Safe ESD safe function cannot be executed.
●
If the fault is triggered during safety operation, operation is
stopped.
●
The Safe STOP safe function is indirectly executed as the SIL
module is no longer supplied with power.
Remedy
→ Check power supply.
Fault of internal 24 V DC
power supply.
The safety-relevant part of the
controls is without power sup-
ply.
IE 24 V AC
It might not be possible to execute the Safe ESD and Safe STOP
safety functions.
Remedy
→ Controls must cool down (for current temperature display, check
controls under: Diagnostic M0022>Device temperatures
M0524>Temp. controls).
→ Check service conditions.
Temperature within controls
housing too high (outside the
specified temperature range).
Wrn controls temp.
It might not be possible to execute the Safe ESD and Safe STOP
safety functions.
Remedy
→ Possible defect at SIL module: Contact AUMA service
Internal error SIL module elec-
tronics sub-assembly.
No signal in display
The Safe ESD safe function can possibly not be executed.
Remedy
→ In case of possible defect at the actuator: Contact AUMA service
Actuator monitoring
Actuator locked during manual
operation.
Possible defect at actuator:
No signal in display
It is possible to execute the Safe ESD safety function. A SIL fault
would occur.
Remedy
→ Check redundant control of Safe ESD signals.
Fault of redundant Safe ESD
wiring. Both signals Safe ESDa
and Safe ESDb are not simul-
taneously at the same level.
No signal in display
7.3. Status signals via output contacts (digital outputs) of standard controls
Actuator controls offer the possibility of signalling status information on safety-related
functions via output contacts (DOUT outputs).
Information Status signals via DOUT outputs are not part of a safety function! They may not be
integrated in a safety-related system! They can be used as additional information
on the standard PLC, for example.
Available signals:
Safe ESD
Safe STOP
SIL fault
SIL function active
Assignment via menu in the display:
Required user level: Specialist (4) or higher.
Device configuration M0053
I/O interface M0139
Digital outputs M0110
Default values:
Signal DOUT 5 = SIL function active
Signal DOUT 6 = SIL fault
7.4. Signal via fieldbus of standard controls
For actuator controls in fieldbus version, status information on the safety-related
functions is provided in the process representation.
