7. DIAGNOSTIC
FUNCTIONS
7.1. Visualisation of the functions
The operator can visualise the
operating condition of the light curtains
through four LEDs positioned on the
receiving unit and two LEDs on the
emitting unit (Fig.19).
SAFE/BREAK LED:
•
SAFE
GREEN LED
when
ON
,
indicates that no objects have been
detected by the device. In this
condition the outputs are ON.
•
BREAK
RED LED
when
ON,
indicates that one object has been
detected. In this condition the outputs
are OFF.
•
ALIGN HIGH LED
:
(yellow)
when
OFF
, indicates the correct
alignment of the last TX optic with the corresponding RX optic (top
side of the device). When continuously ON, indicates that it is
necessary to press the TEST button to reset the device consequently
to an object interception. This occurs only when the device runs
under the manual RESTART mode.
•
ALIGN LOW LED
:
(yellow)
when
OFF
, indicates the correct
alignment of the first TX optic with the corresponding RX optic (low
side of the device).
The LEDs located on the emitter (TX) have the following meanings:

SAFE LED (yellow):
when ON, indicates that the unit is emitting
correctly.
•
POWER ON LED (green):
