Connect line voltage to the control box at the supplied terminal block
and ground. Power can be supplied from the plant service to the
control box or directly from the Mesa melter using the optional power
harness kit.
A potentiometer labeled ”Delay” is for a fill time delay. This delay is
the time duration between the level sensor calling for more adhesive
and when the fill system activates. The delay time prevents the
system from frequently turning on and off. The delay time is preset
from the factory at 60 seconds, but can be adjusted from 0 to 119
seconds. The factory sets the potentiometer at the 12 o'clock
position, sufficient for the majority of applications. For reference, 9
o'clock is 20 seconds and 3 o'clock is 100 seconds.
