MA4 Control Panels and Their Functions
MAIN CONTROL PANEL:
The Main Control Panel is used to operate the melter control system. Controls located on the outer
cover are for operating in AUTO mode only.
OFF: Shuts down power to the control panel, the sealant material pump, agitator and burner.
RUN: Allows the preprogrammed controllers to turn on the pump, agitator, and burner.
CLEAN OUT: Shuts down the burner and reverses pump flow direction to clean out material
from the spray bar and internal plumbing returning the sealant material to the material tank
COOL DOWN: - Shuts down the burner and sealant material pump and turns the agitator only.
This allows the material to cool down more consistently, extending the life of the material remaining in
the tank.
Inside the Main Control Panel box is a Sub Control Panel.
See pages 12-13 for detailed explanation of its use.
