Starting the Melter
Before starting the melter for the first time, confirm that the
melter is fully installed including any required inputs and outputs, gun
drivers, pattern controllers, and timers
melter's operating parameters are set up to support the
current manufacturing process
Refer to Section 3, Installation, if any of the items listed above are
not complete.
To start the melter
1. Switch the melter on.
The melter:
Tests the control panel LEDs
Turns on the heaters (the heaters LED turns green)
Begins to automatically scan through and display the
actual temperature of the tank and each hose and gun that has a
set‐point temperature that is greater than zero degrees. The
sequence of the automatic scan is: tank, each hose and gun pair, and
then back to the tank.
Turns on the ready LED (green) when the tank and all of the
hoses and guns are within 3 C (5 F) of their assigned
set‐point temperature.
NOTE: Appendix D contains a functional description of the pump.
2. Check the air pressure gauge on the front of the melter to confirm that the
operating air pressure is set correctly.
NOTE: The minimum operating air pressure is 0.7 bar (10 psi).
Operating the melter with the air pressure set to less than 0.7 bar (10 psi)
may cause the pump to function erratically.
