PS20 NON STOP DRUM UNLOADER INHIBITION MANUAL
4. The amplifier that adjusts the sensor´s sensitivity is located in the control
cabinet.
This amplifier has two states indicated with two different LED colours (1):
• Green: no adhesive (empty).
• Yellow: there is adhesive (full).
5. Remove the plastic plug of the amplifier to access the sensitivity ad-
justment potentiometer (2) and turn the adjusting screw at least 3 turns
counterclockwise. The LED must be green.
6. With the sensor still covered by melted adhesive, gently turn the adjusting
screw clockwise, just until the LED turns yellow (sensor activated).
7. Gently turn the adjusting screw ¼ turn counterclockwise. The LED will
change back to green.
Verification of the sensor regulation
1. Increase slightly the adhesive level of the tank. The LED should change to
yellow.
2. Decrease the adhesive level of the tank. As soon as the detector is visible,
the LED should change to green.
It is recommended to carry out a verification of the signals once the equip-
ment is in automatic operation.
In Non Stop melters, check which cylinder pushes the adhesive block when
the amplifier LED shows the green colour and stops pushing when it is yellow
colour
