Overview
System Description
Warm melt supply systems are used for melting and
pumping warm melt adhesives and high viscosity seal-
ants.
The system consists of an air-powered ram that drives a
Check-Mate pump and a heated platen into a drum of
material. The heated platen heats the material and the
pump removes it from the drum. The material is then
pushed through a supply hose to the applicator.
All features of the warm melt supply system are con-
trolled by Graco Control Architecture components: Tem-
perature Control Modules (TCM) and the display
module. The TCMs control the heaters, and the display
module provides the user interface for the entire warm
melt supply system.
Power Requirements
A 30A (minimum) - 40A (maximum) circuit breaker (not
provided) must be installed on the incoming power sup-
ply. See T
1 and
48, for more information regarding electrical require-
ments.
Heat Control Zone Selection
Warm melt supply systems have six heat zones (see
F
. 1).
•
Zones 1 and 2 are always used for the heated
platen and the heated pump respectively.
•
Zones 3, 4, 5, and 6 are used for the heated hose
and gun, or a heated regulator. Zones 3 and 4 are
integrated into one receptacle, and zones 5 and 6
are integrated into another. These zones are rated
for 2000 watts at 220 volts.
There are four receptacles with a 12-pin connector on
the control board inside. Heated hoses also have a
12-pin connector on the inlet end cable, and an 8-pin
connector on the outlet end cable. All heated valves,
manifolds and heaters are equipped with a 12-pin con-
nector.
