Installing the RPV-A Autoload Knob Box Control
If your RPV has the RPV-A control package, use the following procedure to install it:
1. Disconnect and lock out power to the Autoloader Hopper Loader.
2. Wire the RPV Material A and B solenoids to the Autoloader Hopper Loader control
box using 16AWG wire. See Figure 3.

in the Autoloader Hopper Loader control box.
Note: The knob box control will not function properly unless you remove this jumper.
