Display Contrast Adjustment
The display contrast is adjusted for optimal viewing at the factory. If the display is not visible when the Hot Melt
Controller powers up, the contrast may need to be adjusted.
Follow the procedure below to adjust the contrast:
1. While holding down the ‘SETUP’ key on the front panel keyboard, simultaneously press the “+” and “-”
keys to change the contrast on the display. This will make the characters on the display brighter and
dimmer, and is considered the fine adjustment.
2. If this does not work, or is not enough to see the display, open the electrical enclosure door to view the
rear of the CPU board.
3. Adjust the Display Contrast Adjustment Pot on the rear of the CPU board using a small screwdriver. (this
requires a very small slotted screwdriver)
4. This is the course adjustment and small incremental turns of this pot will make drastic changes in the
brightness of the display.
Contrast Adjustment - Fine Adjust
Contrast Adjustment - Coarse Adjustment
Contrast Adjustment Pot, Coarse Tune
