2.7.3 Device errors
Outputs If a hardware fault in the internal circuit is detected at an output, all module outputs are dis-
abled (“0” = OFF = safe state).
The relevant diagnostic message is transmitted to the safe controller (see Section “Safe dig-
ital output errors” on page 71).
Serious errors All serious errors that can result in the loss of or adversely affect the safety function cause
the entire module to enter the safe state. The FS LED on the safety module is permanently
on.
The following errors result in the safe state:
– Serious hardware faults in the internal circuit
– User errors
– Module overload
– Module overheating
– Incorrect supply
The relevant diagnostic message is transmitted to the safe controller (see Section “Errors:
Messages and removal” on page 69).
2.7.4 Parameterization errors
Parameterization errors are indicated:
– As long as the module is not parameterized
or
– In the event of faulty parameterization
Parameterization errors cause the entire module to enter the safe state. The FS LED on the
safety module flashes.
In the event of faulty parameterization, the relevant diagnostic message is transmitted to the
safe controller (see Section “Parameterization errors” on page 73).
WARNING: Loss of the safety function due to sequential errors
In the event of a device error, the following measures should be taken to prevent sequen-
tial errors:
Disconnect the module from the power supply and replace it.
Exception:
If an output is operated in stop category 1 and this output is within the switch-off delay time,
then faulty parameterization results in the entire module switching to the safe state only
once the switch-off delay time has elapsed.
