CONTROLLING THE FEED
REMOTE ELECTRIC ACTUATION
To control the timing of the Feed Slide motion
electrically, install the 3-Way Solenoid Valve on top
of the P.O.V. and wire into a Limit Switch. Mounting
a Linear Cam on the Press Ram Slide or installing a
Rotary Cam on the crankshaft are two ways to
electrically control the Feed Cycle.
Many new presses today are equipped with electronic
Programmable Controllers and/or electronic Rotary
Limit Switches. Specify 24 VDC for Solenoid Valve.
