Subject to change without notice
Cause
The configuration in the system plug
does not match the device's func‐
tionality.
The configuration in the system plug
does not match the device's
firmware version.
The safety laser scanner has an
internal fault.
The safety laser scanner has an
internal error.
fault.
The system plug is unsuitable for
the safety laser scanner.
An invalid signal is applied at a reset
input. The reset signal is applied for
too long.
The signal applied at the control
inputs is not assigned to a monitor‐
ing case. The signal is applied for
longer than the set input delay +1 s.
The configured switching sequence
was interrupted by the new monitor‐
ing case.
The input signal for switching
between monitoring cases received
via the network is invalid. The invalid
signal is applied for longer than 1 s.
The input signal for activating
switching between monitoring cases
received via the network is invalid.
The invalid signal is applied for
longer than 1 s.
The input signal for switching
between monitoring cases received
via the network is invalid. The invalid
signal is applied for longer than 1 s.
