• UV Wavelength Calibration Procedure

  10
• 1.After disconnecting the unit from the electrical supply, install the FIVE NEW WAVELENGTH Tubes as directed in Section 9A. (Changing tubes).

  10
• 2.Plug the corresponding UV calibration sensor into the TOP HOLE just inside of the door at the upper right.

  10
• 3.Place the UV calibration sensor in the middle of the floor of the exposure chamber.

  10
• 4.Close the crosslinker door.

  10
• 5.Invoke the calibration mode of the Crosslinker by pushing/holding down STOP on the tactile touchpad and turning the power to the unit ON.

  10
• 6.A sequence of tones will be heard from the Crosslinker and a 180 second count will display on the LED when the calibration procedure has started.

  10
• 7.No calibration occurs during this 180-second period. This period allows a UV tube warm-up and stabilization period.

  10
• 8.Upon completion of the 180-second period, measurements are automatically made with the UV calibration sensor and the crosslinker sensor. These measurements are compared to limits of acceptability and/or if sensor operation is within range.

  10
• 9.If sensor readings are unacceptable, an error code (01, 02, 03 or 04) will flash on the LED Press any key to stop.

  10
• - 8 -

  10
• 10.Check all connections and redo calibration. If the same error message appears, call UVP.

  10
• 11.The previous calibrated operation of the crosslinker will continue following any unsuccessful recalibration. Replace the new UV wavelength tubes with the previously removed old wavelength tubes.

  11
• 12.Successful recalibration to the NEW UV wavelength changes the values in the microprocessor and numeric setting value is displayed on the LED. To return to original or another wavelength the proper UV calibration sensor is needed.

  12
• Chart recorder

  12
• Two probes with banana plug adapters

  12
• One radiometer with UVX-25 calibrated sensor

  12
• Cable with banana plug and jack adaptor to connect radiometer to chart-recorder

  12
• Power source (100V, 115V or 230V)

  12
• Procedure:

  12
• 1.Connect the crosslinker to the power source. Do not turn on the unit at this time.

  12
• 2.Connect the testing probes to the chart recorder and to the crosslinkers PCB as follows:

  12
• PEN 1 (red) to the right side of R7

  12
• PEN 2 (blue) to the right side of R6

  12
• Ground both pens at the lower part of R2

  12
• Note: while connecting these probes, the switches for both pens on the chart recorder should be on ZERO position to avoid possible damage to the recorder.

  12
• 3.Place the UVX-25 sensor inside the crosslinker at the center and slide it through the upper hole of the inner chassis. Plug the sensor into the PCB's jack.

  12
• 4.Select 5V scale for both pens. Turn the chart recorder on.

  12
• 5.Select a speed of 15mm/min.

  12
• 7.Adjust the ZERO position for both pens.

  12
• 8.Press the CHART DRIVE switch.

  12
• - 10 -

  12
• 9.Run the Crosslinker in calibration mode by depressing the STOP/RESET button and turning the power switch on at the same time. At this point, both pens should start recording information on paper. Sometimes either pen will record zero information rega

  13
• 10.During calibration, check the voltage levels on both pens. By adjusting the potentiometers on the PBC, adjust the values for U4 and U5. Depending on the voltage used, from past units it has been found that the optimum values for these levels are:

  13
• VOLTAGERANGE FOR U4RANGE FOR U5

  13
• 115V 3.3-3.5V 2.1-2.3V

  13
• 220V 3.5-3.7V 1.7-2.0V

  13
• 100V 2.5-2.7V 2.6-2.9V

  13
• 11.When the calibration cycle is finished, move both pens to UP and ZERO positions.

  13
• 12.Unplug the UVX-25 sensor and disconnect the probe for PEN 2.

  13
• 13.At this point, it is necessary to check the energy levels of the crosslinker to see if the unit was calibrated properly. Slide the UVX-25's cable through the lower hole of the inner chassis and plug it into the radiometer.

  13
• 14.Connect the radiometer to PEN 2 of the chart recorder.

  13
• 15.Select 1V scale for PEN 2 and a speed of 60mm/min.

  13

  13
• 17.Select an energy level of 600 Joules on the crosslinker and press the START button.

  13
• 18.When the cycle is completed, repeat for 1,200 and 2,000 Joules levels.

  13
• 19.Calculate the actual amount of energy and compare it with the energy selected. They should be within a range of +/- 10%. If this is not the case, adjustments should be made during a repeat calibration. Repeat all the above procedures until the actual

  13
• 20.When the three levels of energy are acceptable, disconnect the sensor and the chart recorder from the Crosslinker. At this point, the unit is ready to be tested.
