Baseline Setting
NOTE:
Refer to
Appendix A, Retrofit Refill System With Nordson Level Sensor,
for updated
information.
Upon setting the probe's height, calibrate the level sensor.
1. Remove the threaded plug on the front face of the level sensor control
box to reveal the adjustment potentiometer.
2. Fill the tank with adhesive and allow it to melt completely.
3. Adjust the liquid level to coincide with the black line on the level probe.
4. If the LED on the control box is amber, turn the adjustment potentiometer
counter‐clockwise until it turns green. If the LED on the control box is
green, turn the adjustment potentiometer clockwise until it just turns
amber. The point at which the LED transitions from green to amber is the
switching point.
5. Once the switching point is found, rotate the adjustment potentiometer
1
/
2
turn clockwise and leave it at that position.
Final Setting
NOTE:
Refer to
Appendix A, Retrofit Refill System With Nordson Level Sensor,
for updated
information.
1. Begin normal operation. Check the adhesive level in the tank after 30
minutes of operation.
2. If the adhesive level is satisfactory, the calibration procedure is complete.
Re‐install the plug over the calibration pot to discourage tampering.
3. If unmelted adhesive is piled up to the top of the tank or the system has
already faulted due to overfilling, rotate the adjustment pot
1
/
2
turn
clockwise to increase the level sensor's sensitivity. Wait 10 minutes and
check the adhesive level again. If the adhesive level is still too high,
repeat this process until the adhesive level is satisfactory. When
finished, reinstall the plug over the calibration potentiometer.
4. If unmelted adhesive has built up on the probe and the adhesive level in
the tank has dropped below the black line on the probe, rotate the
adjustment potentiometer
1
/
2
turn counter‐clockwise to decrease the
level sensor's sensitivity. If the adhesive level is still too low, repeat this
process until the adhesive level is satisfactory.
