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

ABLE

Technical Specifications

, page 

48, for more information regarding electrical require-
ments.

Heat Control Zone Selection

Warm melt supply systems have six heat zones (see 
F

IG

. 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.
