11.2 Possible faults
Important information
NOTE
If a fault response can result in an undesired valid status, you should evaluate the
associated status bits in the logic to initiate suitable measures.
Possible faults and their causes
Table 132: Faults in the logic
Fault Responses Causes
Voltage supply A1 / A2
of the main module is
lower than the operat‐
ing range • Safety controller switches to the
No supply voltage status
• Voltage supply module status bit =
0
•
Status indicators are off
• Fault in the voltage supply
• Line break
• Interruption due to a fuse
Voltage supply of the
main module is higher
than the operating
range • Safety controller switches to the
critical error status
• Internal error module status bit = 0
• Fault in the voltage supply
• Short-circuit to other volt‐
age-carrying line
