1.3 Description Of 319 Power Examination

Table

A. General Description (See Figure 1-1).

The 319 Power Examination Table is an examination table designed specifically for performing general medical examinations and procedures.

When no functions are selected, 115 VAC is supplied to terminals 1 and 2 of all foot switches. There is no path to neutral, however, so no current flows and nothing happens. When the operator selects one of the four up functions (BACK UP, TABLE UP, FOOT UP, or TILT

UP) with the foot control, three paths to neutral are created. Current flows from terminal 2 to terminal 4 of switch and then across the motor pump winding T2 to neutral, starting the motor pump pumping. Current also flows from terminal 2 to terminal 4 of switch and then across the coil of the anti-cavitation solenoid valve, energizing the valve and causing it to open. Current also flows from terminal 2 to terminal 3 of switch and then across the coil of the cylinder solenoid valve and the time delay relay, energizing the valve and causing it to open. The time delay relay delays current flow across the coil of the cylinder solenoid valve for 1/10 of a second, causing it to energize 1/10 of a second after

the motor pump and anti-cavitation solenoid valve have energized. This allows the motor pump to run and oil pressure to build first, so table top will not drift downward slightly before starting to rise. On tables that have an optional treatment pan assembly, the foot function also has a pan safety limit switch in its circuit. If the treatment pan assembly is not pushed into its fully stowed position, the pan safety limit switch will not be tripped. If the pan safety limit switch is not tripped, current flow is interrupted, keeping the cylinder solenoid valve from energizing. This safety feature prevents the table operator from accidentally colliding the foot section into the treatment pan assembly.

When the motor pump starts pumping, suction is created by the rotating pump gears, which allows oil to defeat the reservoir check valve and flow into the pump gears. The pump gears pressurize the oil which flows to the up function shuttle valve. The check ball and shuttle in the up function shuttle valve are pushed to the open position by the oil, allowing oil to flow through the shuttle valve by flowing around the check ball (with the shuttle in the open position, oil is prevented from flowing through the reservoir ports and returning to the reservoir). The oil then flows through the open cylinder solenoid valve at the base of the selected cylinder, extending the cylinder rod. When the cylinder rod extends, oil is forced out of the rod end of the cylinder, through the open anti-cavitation solenoid valve and to the down function shuttle valve. The check ball and the shuttle in the down function shuttle valve are pushed to the closed position by the oil, which prevents oil from flowing through the shuttle valve and into the motor pump, but allows the oil to flow through the newly uncovered reservoir ports into the reservoir. When the cylinder rod reaches the end of its travel, the up function relief valve opens when the pressure reaches 525 - 600

PSI (36.2 - 41.4 BARS) and allows the oil to return to the reservoir. This prevents the motor pump from developing too high of pressures and damaging the hydraulic system components, hoses, or the motor pump itself.

When the operator releases the pedal on the foot control, the path to neutral is opened, causing the motor pump to shut down and the anti-cavitation solenoid valve and the cylinder solenoid valve to de-energize, causing the valves to close.

When no functions are selected, 115 VAC is supplied to terminals 1 and 2 of all foot switches. There is no path

GENERAL INFORMATION to neutral, however, so no current flows and nothing happens. When the operator selects one of the four down functions (BACK DOWN, TABLE DOWN, FOOT

DOWN, or TILT DOWN) with the foot control, two paths to neutral are created. Current flows from terminal 2 to terminal 4 of switch and then across the motor pump winding T3 to neutral, starting the motor pump pumping.

Current also flows from terminal 2 to terminal 3 of switch and then across the coil of the cylinder solenoid valve and the time delay relay, energizing the valve and causing it to open. The time delay relay delays current flow across the coil of the cylinder solenoid valve for 1/

10 of a second, causing it to energize 1/10 of a second after the motor pump and anti-cavitation solenoid valve have energized. This allows the motor pump to run and oil pressure to build before table is operated, so table top will not cavitate. The foot function also has a pan safety limit switch in its circuit. If the treatment pan assembly is not pushed into its fully stowed position, the pan safety limit switch will not be tripped. If the pan safety limit switch is not tripped, current flow is interrupted, keeping the cylinder solenoid valve from energizing. This safety feature prevents the table operator from accidentally colliding the foot section into the treatment pan assembly.

When the motor pump starts pumping, suction is created by the rotating pump gears, which allows oil to defeat the reservoir check valve and flow into the pump gears. The pump gears pressurize the oil which flows to the down function shuttle valve. The check ball and shuttle in the down function shuttle valve are pushed to the open position by the oil, allowing oil to flow through the shuttle valve by flowing around the check ball (with the shuttle in the open position, oil is prevented from flowing through the reservoir ports and returning to the reservoir). The oil then flows through the open anticavitation solenoid valve and into the rod end of the cylinder, causing the cylinder rod to retract. When the cylinder rod retracts, oil is forced out of the base of the cylinder, through the open cylinder solenoid valve to the up function shuttle valve. The check ball and the shuttle in the up function shuttle valve are pushed to the closed position by the oil, which prevents oil from flowing through the shuttle valve and into the motor pump, but allows the oil to flow through the newly uncovered reservoir ports into the reservoir. When the cylinder rod reaches the end of its travel, the down functions relief valve opens when the pressure reaches

250 - 325 PSI (17.2 - 22.4 BARS) and allows the oil to

return to the reservoir. This prevents the motor pump from developing too high of pressures and damaging the hydraulic system components, hoses, or the motor pump itself.

When the operator releases the pedal on the foot control, the path to neutral is opened, causing the motor pump to shut down and the cylinder solenoid valve to de-energize, causing the valve to close.

The anti-cavitation solenoid valve is in the hydraulic system to prevent oil from escaping out of the rod end of a cylinder while the table is not being moved. Otherwise, a cylinder rod would be able to extend on its own if upward pressure was placed on that function of the table top by the doctor or patient.

The cylinder solenoid valves are in the hydraulic system to prevent oil from escaping out of the base of the cylinder assemblies. Otherwise, a cylinder assembly could retract on its own, allowing the table top to drift.

The parts list also illustrates disassembly and assembly relationships of parts.

6.2 Description of Columns

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.

The Part No. column lists the MIDMARK part number for that component.

The Description column provides a physical description of the component.

The Qty. column lists the number of units of a particular component that is required for the subassembly. The letters “AR” denote “as required” when quantities of a particular component cannot be determined, such as: adhesive.

Bullets { • } in the Part No. column and the Description 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.

Likewise, if a component has two bullets, it is a subcomponent of the next component listed higher in the parts list than itself that has only one bullet.

6.3 Torque Specifications and Important

Assembly Notes

When specific assembly torque specifications, measurements, or procedures have been identified, by our engineering department, as required to assure proper function of the unit, those torque specifications measurements, and procedures will be noted on the parts illustrations. Adherence to these requirements is essential.

NOTE

Cut cable ties as necessary to remove cylinders or replace hoses. Before disassembly, take special notice of hose positioning and the cable tie locations securing hoses. Also, note the length and radius of all hose return loops. Duplicating these hose positions, cable tie locations, and loop sizes when re-installing hoses and / or cylinders will ensure the minimum bend-radius of the hose will not be reduced, risking collapse and / or premature failure of the hose.
