The lock-out operational status
In case of certain faults or an erroneous configuration, the device can go into the lock-out operational status. To place the
device back in operation, proceed as follows:
 Rectify the cause of the fault per Table 15 on page 53.
 Switch off the power supply for the SafeZone Mini, wait at least three seconds and then switch back on the power
supply.
Or:
 Restart the safety laser scanner with the aid of the SCD software.
