This combination is only valid if four monitoring cases are configured.
Sequence of monitoring cases
The safe multibeam scanner does not check the order in which the individual monitor‐
ing cases are activated. If necessary, you must ensure the required sequence of moni‐
toring cases externally, e.g. by the device that provides the input signals for monitoring
case switching.
Invalid signals
If a combination of input signals cannot be associated with a monitoring case, the safe
multibeam scanner outputs an error of the category “Recoverable error”.
As soon as the combination of the input signals is valid and can be associated with a
monitoring case, the safe multibeam scanner switches back to normal operation and
activates the corresponding monitoring case.
Input delay
You can configure a switch-on delay between 10 and 500 ms. After the safe multibeam
scanner has detected a change in input states, the inputs are ignored for the duration
of the configured switch-on delay.
If the control device that you use to switch the static control inputs cannot switch to the
appropriate input condition within 10 ms (for example because of the switch’s bounce
times), you need to increase the input delay. The selected input delay must be large
enough to allow your control device to switch to the new input condition within this time.

The universal output (Uni-O) can be assigned various signals for non-safety applica‐
tions, e.g., warning field interruption, contamination or error. The signal level for the
universal output is configurable.
