Anti-Cavitation Solenoid Valve (2, Figure 1-1).

The purpose of the anti-cavitation solenoid valve ( 2, Figure 1-1) is to prevent extending the cylinder rod should upward pressure be applied to the table top through manual lifting. It prevents hydraulic fluid from escaping out of the rod end port of the cylinder when the hydraulic system is

Up and Down Function Shuttle Valves (4 & 5, Figure 1-1).

The Shuttle Valves prevent hydraulic fluid from returning to the reservoir during the specific function. During the "Up" function the check ball in the "Up" function shuttle valve (5, Figure 1-1) seats against the reservoir port, closing the port, preventing the pressurized fluid from entering the reservoir.

GENERAL INFORMATION

At the same time the check ball in the "Down" function shuttle valve (4, Figure 1-1) is repositioned due to the suction and return pressure in the system. This movement opens the reservoir port in the "Down" function shuttle valve (4) to allow fluid to enter the reservoir. During a "Down" function the position of the check balls in the shuttle valves are reversed with the check ball in the "Down" function shuttle valve (4) closed and the "Up" function shuttle valve (5) check ball opened to the reservoir.

Up and Down Function Pressure Relief Valves (7 & 8, Figure 1-1).

The pressure relief valves prevent the hydraulic motor pump from developing too high of pressures that may damage the hydraulic system components, hoses or the motor. The "Up" function pressure relief valve (8, Figure 1-1) opens at 525 - 600 PSI (36.2 - 41.4 BARS). The "Down" function pressure relief valve (7, Figure 1-1) opens at 250 - 325 PSI (17.2 - 22.4 BARS). The valves are preset at the factory and should never be adjusted.

Reservoir Check Valves (Refer to Figures 5-5, 5-6). The motor pump also contains two internal reservoir check valves, one for the "Up" function side and another for the "Down" function side. These two check valves work together to supply hydraulic fluid to the system and prevent the fluid from returning directly back to the reservoir before the base cylinder is operated. When the motor pump starts, a suction pressure is created on one of the reservoir check valves depending on which function "Up" or "Down" is being used. During a "Down" function the "Up" function check valve will open to supply hydraulic fluid to the system. The "Down" function check valve will be closed due to the system pressure and its own internal spring pressure. During an "Up" function the "Down" check valve will open and the "Up" check valve will be closed.

Base Cylinder Solenoid Valve (1, Figure 1-1). The base cylinder solenoid valve (1) allows hydraulic fluid to enter, leave or be retained in the area below the piston of the base cylinder. This allows the cylinder rod to be extended, retracted or held in position depending on which function is being performed. During the "Up" function the solenoid valve is energized and opened. Pressurized fluid is pumped into the cavity below the piston causing the piston rod to extend which forces fluid out on the rod end side of the piston back to the reservoir.

During a "Down" function the solenoid valve is energized and opened. Pressurized fluid is pumped into the cavity on the rod end side of the piston causing the piston rod to retract and forcing fluid out below the piston back to the reservoir. As long as the cylinder solenoid valve (1) is not energized it will remain closed, retaining any fluid in the cylinder.

Time Delay Relay (6, Figure 1-1). The time delay relay (6, Figure 1-1) delays current flow across the coil of the solenoid cylinder valve (1) for 1/10 of a second, causing it to energize 1/10 of a second after the motor pump (3) and anti-cavitation solenoid valve (2) have energized. This allows the motor pump to run and hydraulic fluid pressure to build up before the table cylinder is operated, so the table top will not cavitate.

C. Theory of Operation (See Figures 5-1 thru 5-4 for

wiring diagrams and electrical schematics and Figures 5-5 and 5-6 for hydraulic flow diagrams.)

Electrical Power:

115 VAC line voltage is supplied thru the power cord to terminal board (TB). The foot switch "UP" or "DOWN" pedal must be depressed in order to initiate a function.

Raising Table (Depressing the Table "UP" foot switch).

Depressing the Table "UP" foot pedal actuates the SW1 foot switch which causes the normally closed (N.C.) contacts to open and closes the normally open (N.O.) contacts. Current can flow thru the SW1 N.O. the terminal board TB6 terminal to one side of the anticavitation solenoid valve (ACV) energizing it to the open position. At the same time current flows through TB7 terminal to T2 connector on the motor pump (M1) energizing the "Up" motor winding. Current also flows thru the capacitor (C1) to T3 connector on the motor pump (M1) energizing the "Down" motor winding. The current to the "Down" winding is out of phase with the current at the "Up" winding causing the motor to rotate in the direction for the "Up" function. Current that passes thru the capacitor (C1) also flows to the solenoid coil of the base hydraulic cylinder. Due to the time delay relay (TDR), wired in series with the solenoid coil, the solenoid energizes 1/10 of a second after the motor pump has been running to prevent cavitation of the cylinder. The table top will raise as long as the foot pedal is being depressed or until it reaches maximum height.

Lowering Table (Depressing the Table "DOWN" foot switch).

Depressing the Table "DOWN" foot pedal actuates the SW2 foot switch which causes the normally closed (N.C.) contacts to open and closes the normally open (N.O.) contacts. Current can flow thru the SW2 N.O. the terminal board TB8 terminal to T3 connector on the motor pump (M1) energizing the "Down" motor winding. Current also flows thru the capacitor (C1) to T2 connector on the motor pump (M1) energizing the "Up" motor winding. The current to the "Up" winding is out of phase with the current at the "Down" winding causing the motor to rotate in the direction for the "Down" function. Current that passes thru the capacitor (C1) also flows to the anti-cavitation solenoid valve (ACV) energizing or opening the valve. Current also flows thru SW1 N.O. closed contacts to TB9 terminal on the terminal board to the solenoid coil of the base hydraulic cylinder. Due to the time delay relay (TDR), wired in series with the solenoid coil, the solenoid energizes 1/10 of a second after the motor pump has been running to prevent cavitation of the cylinder. The table top will lower as long as the foot pedal is being depressed or until it reaches minimum height.

The

Item

column of the parts list gives a component its own unique number. The same number is given to the component in the parts illustration. This allows a part number of a component to be found if the technician can visually spot the part on the illustration. The technician simply finds the component in question on the illustration and notes the item number of that component. Then, he finds that item number in the parts list. The row corresponding to the item number gives the technician the part number, a description of the component, and quantity of parts per subassembly. Also, if a part number is known, the location of that component can be determined by looking for the item number of the component on the illustration.

Bullets [ • ] in the column show the indenture level of a component. If a component does not have a bullet, it is a main component of that illustration. If a component has a bullet, it is a subcomponent of the next component listed higher in the parts list than itself that does not have a bullet.
