6.5.5 Closed Loop Calibration Procedure
NOTE You must have Maintenance Access level to perform this procedure.
Tools and Materials Needed:
• Power Puck or other UV Measuring Device (Radiometer)
NOTE Perform all measurements with a cold UV measuring device; ideally the temperature
should be under 25 °C. UV measuring devices are sensitive to humidity, therefore it is
recommended that you store and use within a constant humidity range.
The accuracy of a Power Puck is + /- 10% , typically + /- 5%.
To perform the closed loop calibration:
1. Select
Top Lamp > Parameters > Manu to put the oven in manual mode.
2. Click on
Calibration (Figure 6-17).
Figure 6-17 Closed Loop Parameters Screen – High Power
3. Enter the conveyor speed.
The speed entered in this screen is used only for calibration and calculation; it does not
set the actual conveyor speed.
4. Set
Man Power to 100% (this control box is an active control box; it sets the value).
In case of a cold start, allow the oven to warm-up for 15 minutes before calibrating.
5. Copy the Sensor read value in the Sensor Calibration High Power field.
The UV sensor resolution varies per machine as they are individually validated. The
read value in terms of points represents the analog input value at the PLC.
6. Position the UV puck on a flat carrier or surface and point the puck sensor toward the lamp
top or bottom.
Make sure the puck is at the same height as the substrate to get an accurate UV
measurement.
