results of the diagnostics at hand.
The lock-out operational status
In case of certain faults or an erroneous configuration, the system can go into the lock-out status. The seven­segment
display on the safety laser scanner then indicates , , , , , , , , , or . To place the device back in
operation, proceed as follows:
 Rectify the cause of the fault as per Tab. 18.
 Switch off the voltage supply for the SafeZone Mini for at least two seconds and then switch it back on.
Or:
 Restart the safety laser scanner with the aid of the SCD software.
Extended diagnostics The SCD software is supplied with the devices. It allows you to narrow down the problem if the error is non-specific or if
you experience usage downtime problems. Find detailed information in the online help for the SCD software.
Short-circuit between OSSD
connection 1 and 2  Check the wiring and rectify the error.
General OSSD wiring error  Check the complete wiring of the OSSDs.
The SafeZone Mini is receiving
no measured values within a
range of at least 90°
(measuring range maximum
29.9 m(98.1 ft)), it thus is not
detecting any obstacles such as
e.g. building walls.  For the correct function of the safety laser scanner,
always ensure that measured values are received within
a range of 90°; this range can be moved as required
within the scan range.
Device is faulted.  Check whether the SafeZone Mini is being affected by an
external light source, e.g. headlight, infrared light
sources, stroboscopic light, sun etc.
 If necessary, re-mount the device.
Temperature error. The
operating temperature of the
SafeZone Mini has exceeded
the permissible range.  Check whether the SafeZone Mini is operated as per the
permissible ambient conditions.
Invalid configuration of the
EDM  Verify that the machine-side EDM is connected correctly.
Undervoltage of the supply
voltage  Check the power supply or the connecting cables.
There is a short-circuit between
the input for the control switch
for restart or reset and another
input or output.  Check the wiring for cross-circuits.
Park/stand-by mode,
the OSSDs of the SafeZone Mini
are in the OFF state; the laser is
deactivated. No error. If the criteria for the park mode or the stand-by
mode are withdrawn, readiness for operation is re-
established.
If the display does not go off:
 Test the level(s) at the universal I/O and at the control
inputs that switch to the monitoring case with park
mode.
Optics cover calibration active  No error
Window for light output on the
optics cover contaminated  Clean the window for the light output on the optics
cover.
and
Optical saturation of the
contamination measurement
(there may not be an optics
cover fitted)  Check whether the SafeZone Mini is being affected by an
external light source, e.g. headlight, infrared light
source, stroboscopic light, sun etc.
Or:
 Fit the new optics cover (then perform optics cover
calibration).
