Start-up / Sensor Bandwidth to Mandrel Ratio Calibration
The following procedure must be performed while in Manual mode with all parallel inputs low.
Press the Sensor key repeatedly until LED’s 11 and 12
are lit.
Verify the sensor is operational by moving a web edge
back and forth in the sensor field of view that is nearest
the junction box while watching the signal change in the
bar graph on the CDP-01.
Locate the end of the SE-34 sensor bandwidth by
moving the web edge away from the junction box until
the sensor begins to scan.
(
NOTE: There are 3 configurations of the SE-34. See
left for the different configurations and the approximate
location of the end of bandwidth).
The SE-34 sensor will "scan" looking for a web when
there is nothing present. After the sensor begins to
"scan", slowly move the web back and forth to narrow in
on the precise point of the scan. Make a mark here.
From this point, move the edge of a web into the sensor
(towards the junction box) a distance equal to the total
stroke length of the mandrel. This procedure is
simplified by making a calibration strip cut to the same
width as the guide cylinder’s stroke. The strip should
be kept for future calibrations.
With the web edge stable at this position, press and
hold the F2 and F3 keys until LED’s 5 and 6 are lit
(approximately 3 seconds). Once LED’s 5 and 6 are lit,
it is no longer necessary to hold the web edge stable.
Note: Approximately one minute is required for calculations
in this procedure. If it is desired to abort this procedure, press
and hold the Manual key until LED’s 5 and 6 turn off.
The previous calibration is retained.
Half way through the calculations (approximately 30
seconds), LED 6 will turn off.
Note: If it is desired to abort this procedure, press and
hold the Manual key until LED 5 turns off.
The previous calibration is retained.
When the calculations are complete (approximately 30
additional seconds), LED 5 will turn off.
Position the web in the sensor for normal guiding.
