4.3.4 Power-in Wiring
100–115 VAC
The melt unit comes equipped with an 2.44 m (8 ft) power cord,
unless it is a conduit model.
200–230 VAC
1. Inspect melt unit identification plate and inside electrical panel
to verify actual capacity and type of 230 VAC power plug
required for the system (2- or 3-wire).
2. Open front control panel.
3. Install appropriate power-in 16 AWG wires in the terminal
blocks provided. For automatic systems only, also configure
and install applicator program wires and jumpers. Refer to
Terminal Block Configuration diagram. Liquidtight conduit
and fittings are recommended when routing wires to electrical
terminal blocks. Holes in the chassis are provided for these
installations.
4. Close the front control panel after electrical hookup.
4.3.5 Valve Group Control Circuits for Automatic
Systems
An automatic applicator, or valve, contains one or more adhesive
valves which are activated by a solenoid. A valve group is a
number of valves powered by the same source which activate at
the same time. There are several options to activate electric valves
and valve groups:
Two Types of Valves and Firing Circuits
Automatic applicators are specified by solenoid voltage and valve
type. Valves must match the VAC or VDC firing voltage. Multiple
valve applicators may have more than one firing circuit within a
single applicator.
