Preparation
(contd)
3. Make sure your production line is ready to start. For both motion sensor
sensitivity adjustment and ramp mode power level adjustment you must
run can ends through the dryer.
4. Turn the main disconnect to the ON position.
5. Press the POWER button on the operator panel. The dryer powers up.
NOTE:
With the enclosure doors open and the door interlock switch
overridden, the Cooling Blower Fault LED lights. The motion sensor and
PLC will remain powered for making adjustments. The inverter will not turn
on, so product in the dryer while the fault LED is on will not be cured and
must be removed from production.
Motion Sensor Sensitivity Adjustment
WARNING:
LASER RADIATION!
Do not look directly into the laser beam.
Doing so could result in serious eye injury.
The motion sensor focal point is adjustable between 30
−
60 mm from the
sensor face. Adjust the sensor focus so it senses the motion of the can
ends as follows:
1. Make sure the protective cover is removed from the sensor head.
2. Run product through the dryer.
3. See Figure 13. Observe the LED indicator:
S
Green = Operating
S
Yellow = Reception.
4. Use a small screwdriver to adjust the Distance/Gain screw. The LED
should flash yellow as can ends pass under the sensor head.

Figure 13 Motion Sensor Module
The motion sensor should now be calibrated to your product. As can
ends pass under the sensor head, the Motion LED on the operator panel
should flash.
If the sensitivity adjustment failed, repeat the procedure again. Clean the
sensor head lens with a clean soft cloth if necessary.
