All the functions are hydraulic and controlled by solenoid valves. Someone tried to fix it before me. I think it's more screwed up now. The original problem was that the table would not reverse correctly. The reversing mechanism uses hall effect proximity switches that signal a PLC circuit board. That board shifts a solenoid to reverse the table.

Whereas, the solenoid is home to several important parts, including a coil, sleeve assembly and plunger. Solenoid valves work by employing the electromagnetic coil to either open or close the valve orifice. When the coil within the solenoid is energised, the plunger is lifted or lowered to open or close the orifice.

Solenoid valves are control units which, when electrically energized or de-energized, either shut off or allow fluid flow. The actuator takes the form of an electromagnet. When energized, a magnetic field builds up which pulls a plunger or pivoted armature against the action of a spring. When de-energized, the plunger or pivoted armature is ...

1. Direct-acting solenoid valve. Working principle. When the power is on, the solenoid coil generates the electromagnetic force to lift the closure member from the valve seat to open the valve. When the power is cut off, the electromagnetic force disappears and the spring presses the closure member on the valve seat to close the valve.

A hydraulic solenoid valve is an electromechanical device that helps control the flow of hydraulic fluid in a hydraulic system. It consists of a solenoid coil, a plunger, and a valve body. When an electrical current is passed through the solenoid coil, it creates a magnetic field that attracts the plunger, causing it to move inside the valve body.
