Connect Applicator Signal Wiring
Follow this procedure to connect applicator signal wiring to the melter to
allow full use of the melter's pattern recognition and stitching capability.
NOTE: Applicator signals are routed through the respective hose to a
solenoid valve connector at the end of the hose. When an application
requires more than two applicator signals, the additional signal wiring must
be connected to the hose interface board located inside the melter. A
maximum of four applicator signals can be connected to the melter.
1. Connect the applicator signal wiring as follows:
If an applicator has one solenoid valve, connect the hose solenoid
cable to that solenoid valve and continue to the next procedure in this
section. See Figure 3‐28 later in this manual for an illustration.
If an applicator has more than one solenoid valve, use Y‐cables to
connect the hose solenoid cable to the solenoid valves and continue
to the next procedure in this section. The number of Y‐cables used in
this way is limited by the maximum current specification shown in
Table 3‐3.
If an applicator has more than one independently fired solenoid valve,
continue to the next step to connect the additional solenoid valve
signals to the hose interface board inside the melter.
See Figures 3‐19 to 3‐22 for diagrams of typical applicator signal connection
setups.
