WIRING DIAGRAMS
Pressing the foot switch completes the circuit to energize the valve coil. The limit switch is spring
loaded and normally open. It is triggered by a cam on the rotary disk shaft. Moving the angle
adjuster from 0 deg. to 180 deg. positions the limit switch closer to or farther away from the cam.
This controls how much the rotary disk must turn before it triggers the limit switch. When the limit
switch is triggered, it energizes the relay which will open the valve coil circuit, causing the rotary disk
to rotate back to the starting point.
