The control box contains the membrane panel and PCA. It connects to the
melter via the supplied bracket. An optional remote mount kit is available to

Membrane Panel
The front panel of the electrical control box shown in Figure 4 contains three
LEDs that have different colored lights to indicate the unit condition:

Pressing the Enable button will toggle the indicator.
Enable button - Press the enable button to turn the fill system on or

adhesive is being transferred from the adhesive storage bin into the
melter tank through the transfer hose.
Fault LED (red light) - activates if the system exceeds the user
defined fill time limit. The system will not resume operation until the
fault is cleared with the clear fault button.
