Connecting a Pressure Control Signal
If your melter has the flow control bypass option (option F), make the
electrical connections shown below. Refer to Pressure Control Options in
Section 2, Description, for a detailed description of the pressure control
options. To determine the configuration of your melter, refer to Melter Part
Numbers in Section 7, Parts.
To connect wiring for the flow control bypass option (F)
SeeFigure3-8.Connectacustomer-supplied 24V control signal to the
pressure control option terminal block (1) located inside the electrical
enclosure. Terminals are not polarity-sensitive.
With this pressure control option, the output pressure supplied to the
pneumatic PCV (3) is controlled with the F option air pressure regulator (2)
when no signal is provided to the solenoid. When a signal is provided to the
solenoid valve, the output pressure to the pneumatic PCV corresponds to the
melter supply pressure.
