Device errors can stop safe communication.
If a hardware fault in the internal circuit is detected at an input, all module inputs
Inputs
enter the safe state. The value "0" is represented in the process image of the inputs
("0" = safe state).
The diagnostic message is transmitted to the controller: see
and removal" on page
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 module is per-
manently on.
The following serious errors result in the safe state:
•
Serious hardware faults in the internal circuit
•
User errors
•
Module overload
•
Module overheating
•
Incorrect supply
The diagnostic message is transmitted to the controller: see
and removal" on page
WARNING
Sequential errors can result in the loss of the safety function.
•
In the event of a device error, the module should be disconnected completely
from the power supply and replaced so as to prevent sequential errors.
Parameterization errors are indicated in the following states:
•
Faulty parameterization
The module switches to the safe state following parameterization errors. The
FS LED on the module flashes.
In the event of faulty parameterization, a diagnostic message is transmitted to the
controller: see
"Parameterization errors" on page
