Verify the station
is
configured properly
and
that the sensor is
mounted on its mounting
pole
in
approximately the correct
position per the installation drawing for your system.
Verify the wiring connections
from
the sensor to the Main
Terminal
Block
TB1
in the
FT
-
50/70
Inspection Head. Use thestandard wiring information presented in the
FT
-
50/70
manual
and
Drawing

at
the back
of
this appendix. If the
TB1
pin
connections are not standard, a separate wiring diagram will be
included in the documentation sent with your system.
SETUP, ALIGNMENT AND CALIBRATION PROCEDURES
The procedures in the following paragraphs give step-by-step
instructions for the mechanical alignment and electrical
calibration of the Ultraviolet Label Detector Sensor/Amplifier.
Before setting up the Ultraviolet Label Detector, The
FT
-
50/70
Inspection Head Trigger, Encoderand Rejector must be set up
and calibrated.
In
addition, the bottle guides must be positioned
to deliver the bottles to the center
of
the conveyor.
Place a productionbottle on the conveyor
at
the Sensor
centerline and in the approximate position
of
a bottle delivered
by the bottle positioning guide rail.
Adjust the position
of
the UltravioletLabel Sensor
so
that the
sensor
will
intersect the label at
its
widest point. There are two
adjustment knobs on the Detector; one each for the vertical and
the horizontal. Both
will
need to be adjusted to position the
sensorapproximately
1.6
inches from and perpendicular
to
the
label surfaceat a height that allows the sensor to detect the
largest portion
of
a properly positioned label. The final sensor
height
will
be a function of the label fluorescence and sensor
calibration setting.
Firmly tighten the
locking
knobs on the bracket.
Mechanical Alignment
Calibration
Refer
to
your
FT
-
50/70
manual for power turn
-
on and electrical
startup procedures. After the power
is
on, perform the following
calibration steps.
Remove the washdown coverand set aside.
Beforeattempting to calibrate the sensor, make sure the lens on
the front
of
the sensor
is
clean and unobstructed.
