UV CROSSLINKERS | UVP |
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 regardless of the lights in the crosslinker being on, if this is the case, check for bad connections.
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:
VOLTAGE RANGE FOR U4 | RANGE FOR U5 | |
115V | ||
220V | ||
100V | ||
11.When the calibration cycle is finished, move both pens to UP and ZERO positions.
12.Unplug the
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
14.Connect the radiometer to PEN 2 of the chart recorder.
15.Select 1V scale for PEN 2 and a speed of 60mm/min.
16.Lower both pens, turn the CHART DRIVE switch on, change the pens' switches to MEASURE position and adjust for zero level.
17.Select an energy level of 600 Joules on the crosslinker and press the START button.
18.When the cycle is completed, repeat for 1,200 and 2,000 Joules levels.
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 levels are within range.
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.
