SPECIAL USER ATTENTION

The extreme positioning capabilities of the 6002 Series Table requires special attention for possible interference points when using multiple function positioning. As with the operation of any surgical table, a certain amount of care should be exercised to position the patient safely. Although the thick pads and sheets substantially protect the patient, pinch points, located at the joints of the top section should always be considered. BE SURE THAT THE ARMS, HANDS AND FINGERS OF THE PATIENT AND THOSE OF THE OPERATING ROOM PERSONNEL ARE CLEAR OF ALL MOVING PARTS BEFORE POSITIONING THE TABLE. Proper restraints should always be used for patient safety.

Certain accessories such as the Uro-Drain Tray, Armboards and X-Ray top can be damaged when changing the position of the table top sections. Always look first to see if a desired movement is going to interfere with any accessories in use.

The operator has the ultimate responsibility of preventing damage to the table and surrounding equipment or possible injury to the patient or staff. In general, common sense will dictate when there is a potential hazard.

The following precautions should be reviewed by all personnel prior to operating the table.

WARNING

Risk of electrical shock. Make sure power cord is disconnected prior to accessing fuses.

NOTE

Activating any function button will activate the brake system. Using the TABLE UP function to set the brakes provides a visual assurance that the brakes are locked. As the brake cylinders are extending, the entire table will move slightly. When the table top begins to elevate, the brakes are fully locked.

WARNING

DO NOT unlock brakes when a patient is on the table. An uneven patient weight load may cause instability.

•Never operate the table without ensuring that the brakes are set.

WARNING

Possible explosion hazard exists if table is used in the presence of FLAMMABLE ANESTHETICS.

A routine Instructional Program should be implemented by the facility for proper usage instructions for all personel that may operate this table.

WARNING

Indicates a possibility of personal injury.

CAUTION

Indicates a possibility of damage to equipment.

NOTE

Indicates important facts or helpful hints.

NOTE

The table will operate correctly on battery power with the power cord connected to a wall outlet or disconnected.

NOTE

Battery Operation must be turned OFF at the pendant control. It can not be turned Off using the main power switch.

NOTE

If the table is stored for a period greater than 6 months, the batteries should be removed and stored in a dry, clean condition at a storage temperature of 68° F (20° C). Batteries should be recharged every 6 months of product storage.

SPECIAL USER ATTENTION

NOTE

When the amber light starts to blink (indicating low power in battery) the table will operate for approximately 5 continuous minutes, typically long enough to use the table for the rest of the day.

NOTE

The charging system operates ONLY when the table is in AC120V operation mode.

NOTE

The table can be operated on 120VAC power while the battery is being recharged. The green AC 120V indicator light (on the pendant control) will illuminate confirming 120VAC operation.

NOTE

The emergency back-up control switches will function when the table is operating on 120VAC power, battery power, or turned off.

WARNING

Remove major contaminants from the table with disposable materials following appropriate biohazard waste disposal procedures.

Remove all table pads and place them on a flat surface for cleaning.

CAUTION

Thoroughly read and follow the manufacturer's directions for all cleaning fluids. DO NOT use cleaners containing phenolics.

Apply cleaning fluid liberally to top and sides of each pad and wipe with a clean lint-free cloth.

Using a clean, damp, lint-free cloth, wipe the pads to remove the cleaning fluid.

Using a clean, dry, lint-free cloth, wipe the pads to remove all moisture.

Repeat the steps to clean the bottom of the each pad.

CAUTION

Caution should be taken when cleaning the table to prevent excessive fluid entry into electrical connectors.

Electro-Hydraulic System

SECTION I HYDRAULIC SYSTEM

The hydraulic system (with the exception of the hydraulic cylinders and hoses) is contained within the base of the table. The hydraulic valves and pump are electrically controlled by the use of a hand-held push button pendant control. The power requirements for the table are 120 VAC, 5 amp, 60 Hz.

The table contains the following components. Refer to the block diagram (figure 1-1) for relationship.

a. Oil Reservoir - Main oil supply. Approximately two quarts.

b. Motor/Pump Assembly - A positive displacement gear type pump provides the necessary oil pressure and volume.

a. Motor/Pump Operation

The motor/pump assembly is a gear type pump that provides the oil pressure and volume for the entire hydraulic system. The pump has an inlet side and an outlet side. The inlet side is connected to the reservoir which provides the oil supply. The reservoir has a very fine mesh screen strainer which prevents foreign material from entering the oil system.

The output line of the pump is connected to the main oil galley which is internal and common to all the hydraulic mini-valves and pressure relief valve. Also, common to the hydraulic mini-valves and pressure relief valve is an oil galley that internally connects to the oil reservoir to provide a return path for the hydraulic oil. See figure 1-2.

b. Pressure Relief Valve

The main component of the valve is an adjustable spring loaded plunger that is pushed off from its seat by the oil pressure. The oil then flows back into the reservoir. See figure 1-4 Turning the adjustment nut clockwise increases the amount of oil pressure required to open the valve, and turning it counterclockwise decreases the amount of oil pressure. (See adjustment section for specification.)

SPRING LOADE PLUNGER

This device provides an alternate oil path when the hydraulic cylinders reach the end of their stroke and the pump continues to run. If this path were not provided, the pump motor would stall because the oil cannot be compressed. The pressure relief valve is directly connected to the mini-valve bodies and shares both the common internal main pressure oil galley, and the return oil galley, that internally connect to the reservoir. See figure 1-3.

Figure 1-4 . Pressure Relief Valve

Functioning

c. Mini-Valves

The operation of the mini-valves is identical for all table functions except the elevation and Single Action Brake circuits. These two hydraulic circuits use a 3-way (single check valve) type mini-valve. All other functions use a 4-way (dual check valve) type mini-valve.

Either type mini-valve is controlled by two pushing type, electrically operated solenoids. The solenoids push the spool valve (located in the lower portion of the valve) one way or the other. This motion opens the main supply galley (which has pump pressure) allowing the oil to flow through the various parts of the mini-valve to the function. The spool valve also opens an oil return circuit which allows the oil to return to the oil reservoir.

The main components of the mini-valve and their functions are listed below:

1. Spool Valve - Opens the main oil galley (pump pressure) to either mini-valve outlet depending on which direction the spool valve is pushed. Also it provides a return path for the oil returning back into the reservoir.

Also, by using this control method, it doesn’t matter what size cylinder and piston is used because the speed can be controlled by restricting the return oil. If the pump puts out more volume to a certain slave cylinder than the speed control is allowing to go back to the reservoir, the pressure relief valve provides an alternate path for the pump oil.

d. Mini-Valve in Neutral Position

(No fluid flow) See figure 1-5.

1. Spool Valve Centered - This closes off both

oil pressure and oil return galleys.

2. Pilot Plungers Both Closed -The pilot plungers control the opening of the check valves. If they are closed, the check valves must be closed.

3. Check Valves - Both check valves are closed trapping the oil in the cylinder and oil lines.

4. Speed Adjustment - When the mini-valve is in the neutral position, the speed adjustment does not affect anything because there is not any oil flow.

2. Pilot Plunger - There are two plungers in a four-way mini-valve (one in a 3-way mini-valve), one under each check valve. The purpose of the pilot plungers is to mechanically open the return check valve allowing the oil to return back into the reservoir.

3. Check Valve - Two are provided in each fourway mini-valve to seal the oil in the cylinders and oil lines and prevent any movement of the table. One check valve is provided in a 3-way mini-valve.

4. Speed Adjustments - There are two speed adjustments in each mini-valve. They are needle valve type controls which restrict the volume of oil returning back into the reservoir, thereby controlling the speed of the table surface movement. A 3way mini-valve has only one speed adjustment.

The speed controls are always located in the return oil circuit. This prevents uncontrolled movement of the piston in the slave cylinder due to one side of the piston being loaded with hydraulic pressure and the other side having no load.

1. Spool Valve - Pushed to the left by electric solenoid. This opens the internal oil pressure galley allowing the fluid to go through the check valve and on to the cylinder.

Also, the spool valve opens the oil return line providing an oil path through the internal oil galley back to the reservoir.

2. Pilot Plunger Valve - Left pilot plunger valve is pushed up by the incoming oil pressure mechanically opening the check valve located above it in the return circuit. This action allows the oil from the left side of the slave cylinder to go back into the reservoir. The right pilot plunger valve is not affected in this operation mode.

3. Check Valves - Both check valves are opened in this operation mode. The right check valve is pushed open by the oil pressure created by the pump. The oil then continues to go through the lines and pushes the slave cylinder piston to the left. At the same time, the left check valve is held open mechanically by the pilot plunger providing a return path for the oil through the mini-valve back to the reservoir.

4. Speed Adjustment - The right speed control (output side) does not have any effect in this operation mode because the oil is routed around the speed adjustment through a by-pass valve and then to the output port. The left speed adjustment controls the speed of the table function by restricting the amount of oil going back into the reservoir.

2. Pilot Plunger Valve - Right pilot plunger valve is pushed up by the incoming oil pressure mechanically opening the check valve located above it in the return circuit. This action allows the oil from the right side of the slave cylinder to go back into the reservoir. The left pilot plunger valve is not affected in this operation mode.

3. Check Valves - Both check valves are opened in this operation mode. The left valve is pushed open by the oil pressure created by the pump. The oil then continues to go through the lines and pushes the slave cylinder piston to the right. At the same time, the right check valve is held open mechanically by the pilot plunger providing a return path for the oil through the mini-valve back to the reservoir.

4. Speed Adjustment - The left speed control (output side) does not have any effect in this operation mode because the oil is routed around the speed adjustment through a by-pass valve and then to the output port. The right speed adjustment controls the speed of the table function by restricting the amount of oil going back to the reservoir.

2. Trendelenburg Cylinder Assembly - This cylinder / piston arrangement has rack teeth cut into the top of each piston. These teeth mesh with a pinon gear that is connected directly to the table side frames. The pinion gear shaft and table side frames are supported by bearings at either side. When hydraulic fluid is pumped into one side of the cylinder, the pistons are pushed in one direction, moving the pinion gear and table side frames with them. Oil pressure can be applied to either side of the piston, making the table tilt end for end. See figure 1-10.

arrangement, this ram is connected to a movable table surface. The movable surface can be moved one way or the other by pumping hydraulic fluid into the cylinder on either side of the piston. Obviously, if oil is pumped into one side of the cylinder, a return path must be provided for the oil on the other side. See figure 1-9.

3. Lateral Tilt Assembly - The lateral tilt assem-

bly consists of two cylinders, pistons and connecting rods. The connecting rods attach to the lateral tilt lever which connects to the table side frames. When hydraulic fluid is pumped into one cylinder, the piston and connecting rod pushes the lateral tilt lever which tilts the table top to one side. To tilt the table top in the opposite direction, fluid is pumped into the opposite cylinder. See figure 1-12.

5. Brake Cylinders - The brake cylinders are single action type similar to the elevation cylinder. The movable piston's ram is connected to a brake pad. See figure 1-14. Oil pumped into the top of the cylinder pushes the piston down raising the table base off its casters. An internal return spring on the bottom of the piston, pushes the piston up to return the oil through the mini-valve to the reservoir.

4. Elevation Cylinder - This single action cylinder does not have hydraulic fluid on both sides of the piston. It depends on the weight of the table top assembly to lower it. The cylinder is set in the center of the elevation main column. The cylinder is elevated by the driven force of the oil pressure. When lowering, the oil that

is accumulated in the cylinder is returned to the oil reservoir through the mini-valve due to the table top weight. A slider support assembly is used to support the

h. Elevation Cylinder Return Circuit

weight of the upper table section. A stainless steel shroud covers the flexible hydraulic hoses and slider. See figure 1-13.

Three-way (single check valve type) mini-valves control both the elevation and return circuits. The elevation circuit operation within the mini-valve is identical to the operation of the four-way valves previously described (inlet pressure opens the check valve allowing the oil to enter the cylinder). In the return position, inlet pressure pushes the pilot plunger up and opens the return check valve. See figure 1-15. The open check valve allows a path for the oil in the elevation cylinder to return to the reservoir. When the pilot plunger valve is opened, the continuing pump pressure opens the pressure relief valve which provides a return oil path to the reservoir.

Figure 1-13. Elevation Cylinder Assembly

The mini-valve used in the elevation circuit con-

tains only one check valve (all four-way minivalves use two check valves). The check valve is used to trap the oil in the elevation cylinder thereby supporting the table top. When the top is being lowered the check valve is mechanically held open by the pilot plunger through pump pressure.

Each corner of the cast-iron table base has a hydraulic brake cylinder. These single action cylinders are hydraulically connected in parallel to the mini-valve and all four are activated together. It is normal for one corner of the table to raise before the others due to the weight distribution of the table.

An electronic timer in the relay box is activated when any function on the pendant control is pushed momentarily. The pump/motor and brake system mini-valve are activated and the brake cylinders are completely set. The electronic timer runs for approx. 8-10 seconds.

k. Flex/Reflex System

The emergency brake release is simply a manually operated bypass valve connected in parallel to the brake cylinders and the oil reservoir. See figure 1-

17. When the valve is opened (turned counterclockwise) a return circuit for the brake hydraulic fluid is opened. The return springs force the pistons up pushing the hydraulic oil back into the reservoir and retracting the brake pads.

EMERGENCY BRAKE RELEASE LEVER

The Flex/Reflex system used on the present tables incorporates an additional mini-valve (7 total) which connects the trendelenburg and back section hydraulic systems in a series. When FLEX is activated by the pendant control, the Flex/Reflex minivalve opens the oil pressure path to the Reverse Trendelenburg piston. The return oil path from the trendelenburg piston is routed through the back section cylinder to the mini-valve return port. See

a. Fluid Level.

The fluid level should be approximately 1/2" below the filler hole or gasket surface. If additional fluid is needed, remove the filler vent cap with a phillips screwdriver and add fluid through this opening using a funnel. See figure 1-19.

NOTE

The elevation cylinder should be completely down and all the other control functions in their neutral position when checking oil level.

FILLER VENT

FILLE CAP

c. Pressure Relief Valve

The pressure relief valve is adjusted by turning the adjustment nut until the desired pressure is reached.

To adjust:

1. Remove the blind cap and attach a hydraulic pressure gauge to the main oil galley using a 6mm plumbing bolt. See figure 1-20.

RESERVOIR OPENING

Figure 1-19.

The type of oil that should be used is Mobil DTE #25 or equivalent. This is a very high quality hydraulic oil. The table requires approximately two quarts of oil to operate properly.

b. Bleeding The Hydraulic System

To purge the air from the hydraulic system, operate each function back and forth at least two or three times.

NOTE

Whenever a hydraulic line or component is replaced, bleed the air out of the lines using the pump pressure before making the final connection. Then operate the function until it stalls in both directions.

Figure 1-20.

2. Raise the table top until the piston reaches the end of its stroke and stalls. Observe reading on pressure gauge and turn the adjustment nut (clockwise to increase oil pressure, counterclockwise to decrease) until desired reading is obtained. Pressure should be 80KG/CM† -1138 PSI.

Page 9

d. Speed Controls

The speed controls restrict the volume of oil returning back to the reservoir thereby controlling the speed of each control function.

All four-way mini-valves, have two speed controls located in the ends of each valve body. All threeway mini-valves have only one speed control.

One speed control adjusts one direction of a particular function and the opposite speed control adjusts the other direction. They are adjustable by using a small straight blade screwdriver and turning the adjustment screw clockwise to decrease the speed and counterclockwise to increase the speed. Refer to figure 1-21.

A pressure gauge should be used to set the speed of the back section, trendelenburg and flex control functions.

To adjust:

1. Attach the pressure gauge onto the main oil

galley as shown in figure 1-21.

2. The gauge should read the following values when operating the various control functions in either direction. Turn the speed controls until desired values are obtained.

Back Section Up 65KG/CM†-925PSI

Dn 65KG/CM†-925PSI

Trendelenburg Up 65KG/CM†-925PSI

Dn 65KG/CM†-925PSI Flex 70KG/CM†-995PSI Reflex 70KG/CM†-995PSI

Figure 1-21.

Any control function should move in either direction at the same rate. If the rate of a certain function is too slow, open the speed control slightly and recheck. Use the second hand on a watch and time a particular function. Match that time in the opposite direction by opening or closing the speed control. Approximate operating times are as follows:

Lateral Tilt 7 seconds Back Up 25 seconds Back Down 15 seconds

NOTE

When adjusting Flex/Reflex speed controls, set Reflex last.

Elevation - There is not a speed adjustment for raising the table. The speed control will only affect the rate of descent and it should equal the rate of elevation.

Back & Foot / Leg Sections The hydraulic cylinder rams that control both the

back and foot / leg sections must move together so that these sections are not twisted when operated. This is accomplished by the use of eccentric cams that move the cylinder bodies fore and aft to adjust their effective stroke.

NOTE

Adjust gear mesh before adjusting eccentric cams for the back section.

a. Back Section

Position the back section all the way up until it stalls. Both sides of the back section should stop moving at the same time and should not show any signs of twisting.

Position the leg section all the way up. Both sides of the leg section should stop moving at the same time and should not show any signs of twisting.

Any twisting or flexing of the leg section as it approaches the stalled position indicates that one of the cylinders is not reaching its fully extended position at the same time as the other and an adjustment is required.

To adjust: Loosen the cam locking nuts located inside the

table side frames. Use a spanner wrench to turn the cylinder eccentric cams as required to shift either cylinder fore or aft as needed so no twisting or flexing of the leg section is observed when it is stalled in the above horizontal position. Tighten locking nuts when proper adjustment is achieved. See figure 2-3.

Any twisting or flexing of the back section as it approaches the stalled position indicates that one of the cylinders is not reaching its fully extended position at the same time as the other. This condition would require an adjustment.

SECTION III HYDRAULIC TROUBLESHOOTING

3-1. Precautions

Before attempting to troubleshoot any hydraulic problem on the table, please read through the precautions and notes below.

CAUTION

When disconnecting any of the hydraulic lines, fittings, joints, hoses, etc., for the following control functions, be sure these table surfaces are in their down position or completely supported.

•Elevation

•Back Section

•Leg Section

When working on the trendelenburg or lateral tilt hydraulic circuits, be sure to support the table top. When working on the brake system make sure the brakes are completely retracted.

Once the problem has been determined, concentrate on that particular hydraulic circuit or control function.

Listed below are the hydraulic components that are common with all hydraulic circuits. If there is a problem with any of them, it could affect all control functions.

1. Motor/Pump Assembly

2. Reservoir

3. Pressure Relief Valve

4. Certain Oil Lines and Galleys

If there was a problem in the following components, only one control function would normally be affected.

1. Mini-Valve

2. Slave Cylinder

3. Oil Lines

NOTE

CAUTION

Failure to follow these precautions may result in an uncontrolled oil spray and damage to the table or personal injury.

3-2. Troubleshooting Notes

When troubleshooting a table malfunction, first determine the following:

1. Does the problem affect all control func-

tions?

2. Does the problem affect only one control

function?

3. If the problem affects one control function is

it in both directions?

Whenever a hydraulic line or component is replaced, bleed the air out of the lines using the pump pressure before making the final connection. After all connections are tight, cycle the control function back and forth two or three times to purge the remaining air from the system.

CAUTION

When installing new "O" rings use hydraulic oil to thoroughly lubricate the "O" rings and cylinder. Keep everything clean.

Each complete oil circuit is shown on the following pages. When troubleshooting a particular function, refer to the appropriate oil circuit diagram and the list of possible problems

4. Is the problem intermittent?

5. Is the problem no movement of a table

surface or does the table surface lose position?

SECTION IV ELECTRICAL SYSTEM

4-1. General

The complete electrical system (with the exception of the hand-held pendant control and the return circuit micro-switches) is contained within the base of the table. The pump motor and the hydraulic valves are controlled electrically with the pendant control.

The electrically operated functions are as follows:

- ELEVATION - Up and Down

- TRENDELENBURG - Head up and down

- LATERAL TILT - Right and left

- BACK SECTION - Up and Down

- LEG SECTION - Up and Down

- FLEX / REFLEX

- RETURN TO LEVEL

4-2. Components

Refer to figure 4-1 for the relationship of the electrical components.

a. Wires, Connectors, Switches, Fuse - These

provide the path for the various electrical circuits.

b. Relay Box - Contains the step down transformer, full wave rectifier, and relay switches. The relay switches are activated by the pendant control and in turn energize the solenoid.

c. Hand-Held Pendant Control - Closes microswitches to activate relay box. Operates on 5 VDC.

d. Solenoids - These electrically open and close the hydraulic ports of the mini-valve to direct the fluid to the correct cylinders. They operate on 120 VAC.

e. Motor/Pump Assembly - 120 VAC, 60 HZ, 200 Watt capacitor induction motor.

- BRAKE UNLOCK - Brake release

The power requirements are 120 VAC, 60 Hz, fuse protected. The main power on-off switch is an enclosed DPST type and the power cord is a threewire, fifteen foot long, UL listed cord with a threeprong hospital grade plug.

4-3. Battery Model Components

The functions of the battery model tables are the same as the standard 120 VAC models. The electrical components and operation however, vary greatly between the two models. To simplify the troubleshooting procedures, the battery model tables are covered separately in Section VI.

Page 22

SECTION V ELECTRICAL SYSTEM TROUBLESHOOTING

5-1. Troubleshooting Notes

The basic operation of each component will be defined along with a drawing and explanation on how to check it out.

NOTE

This section does not cover the battery table components. They are

covered separately in Section 6.

Certain defective components could cause the entire table to stop functioning or only one control function to stop. It would depend on what part of the component failed. Other defective components would only cause one control function to stop.

The following defective components could cause all control functions to be affected:

a. Motor/Pump Assembly (starting capacitor) b. Main Switch Circuit and Wiring

The following defective components could cause all control functions to be affected or only one control function:

a. Relay Box b. Pendant Control

The component listed below would only affect one control function:

Solenoid

1. Plug the power cord into the 120VAC power supply (wall receptacle) and turn ON the main switch.

2. Disconnect connector CN4 from the relay box. See figure 5-1. Leave all other connectors connected.

RELAY BOX

Figure 5-1. Main Power Test

WARNING

Line voltage (120 VAC) will be measured in this test. Do not touch uninsulated connector pins or meter test leads.

3. Use an AC voltmeter capable of measuring 120 VAC and measure the voltage between pins 1 and 2 (black and white wires) located in connector CN4. See figure 5-2. You should receive line voltage 120 VAC.

When troubleshooting an electrical circuit, start at the problem and work back to the power source.

5-2. Main Switch

The main power supply, 120 VAC, 60 HZ, comes in through the power cord and through the main switch. The main switch opens both lines when in the "OFF" position. An 8 amp or two 10 amp fuses are used to protect the complete electrical system and are located next to the main switch.

a. Main Switch Test

The following test will determine if line voltage is applied to connector CN4, which in turn would power the table.

b. Test Results

If you do not receive the correct voltage measurement, the problem would have to be in the wires, main switch, fuses, or power cord. If the correct voltage is obtained, everything is good up to this point and the problem would have to be in another area.

5-3. Pendant Control

The Pendant Control consists of 14 micro-switches (buttons). When any of the circuits are completed (by depressing a control button) the appropriate relay contacts (located in the relay box) close applying 120V potential to the appropriate solenoid to operate the mini-valve and the pump/motor. The Pendant Control has only 5-6 volts applied to it.

a. Pendant Control Test

The following test will determine if the microswitches inside the Pendant Control are functioning correctly.

1. Unplug the pendant control from the base of the table. You will be checking the cord side connector.

2. Use an ohmmeter R x 1 scale and check the continuity between pin 1 and pins 4 through 19. See figure 5-3.

3. Ohmmeter must show continuity between the pins that are indicated when the appropriate buttons are pressed.

NOTE

Pins 2 and 3 are connected to the LED (power on light on the pendant control) and cannot be checked with an ohmmeter. Pins 17 & 18 are not used.

Page 24

Figure 5-3. Pendant Control Test

b. Test Results:

If you do not receive continuity between any of the pins, either the micro-switch in the Pendant Control is defective or a wire is broken. Either of these problems can be repaired easily.

If you receive correct readings with the meter, the Pendant Control is okay.

c. Wiring Harness Test

The following test checks the wires leading from the relay box connector CN8 to the 19 pin connector table socket. These wires apply low voltage to the pendant control buttons.

1. The power cord should be plugged into the

wall socket and the main switch turned ON.

d. Test Results:

If you do not receive the correct voltage reading, the wiring or connector pins may be faulty. Disconnect connector CN8 from the relay box and using an ohmmeter, test the continuity between the corresponding pins in connectors CN8 and the table base connector. See figure 5-5. If the correct readings are obtained, this part of the circuit is okay.

2. Disconnect the pendant control from the base connector. All other connectors should be connected.

3. Use a DC voltmeter 10V scale and measure the following pins located in the 19 pin table base connector. See figure 5-4.

NOTE

Pin 19 will have no voltage potential unless one of the return-to-level microswitches are activated, i.e. trend or tilt . Pins 17 & 18 are not used.

5-4. Relay Box

The 120 volt power supply is directly connected to the relay contacts. When these contacts are closed, 120 volts is supplied to the solenoids which are mounted on the hydraulic mini-valves. One relay is used to supply 120V to the pump/motor and is always activated no matter what control function is selected. The brake locking circuit relay is also activated when any control function other than BRAKE UNLOCK is initially selected.

Also, inside the relay box is a step-down transformer and full-wave rectifier which decreases the line voltage to 5.5 volts. This low voltage potential controls the relays by the use of the hand-held pendant control buttons. Basically the relays enable a 5.5 volt potential to control the 120 volt circuit.

Figure 5-4. Table Base Connector

The following tests will determine if the relay box is functioning correctly.

a. Relay Box Input Connector CN4

1. Plug the power cord into the 120 VAC power supply (wall receptacle) and turn the main switch ON. Leave all connectors connected.

d. Test Results:

Line voltage (120 VAC) will be measured in this test. Do not touch uninsulated connector pins or meter test leads.

2. Use an AC voltmeter capable of measuring 120 volts and measure the voltage between pins 1 (white) and 2 (black) of connector CN4 for input voltage. See figure 5-6. Meter should read line voltage 120 VAC.

3. Activate any table function with the Pendant Control and using an AC voltmeter, test the voltage at pins 3 and 4 of CN4 for output to the pump. Meter should read 120 VAC.

b. Test Results:

If you do not receive the correct meter readings, the relay box or wiring is defective. If the correct readings are obtained, this part of the relay box is okay. Proceed to the next step.

e. Relay Box Output Connectors CN6 & CN7

This test checks the high voltage (120V) that is used to energize the solenoids.

WARNING

120 VAC will be measured in this test. Do not touch uninsulated connector pins or meter test leads.

1. The power cord should be plugged into the

wall receptacle and main switch turned ON.

2. Disconnect the motor connector CN15. All other connectors should be connected. Test connectors CN6 and CN7 from the back while attached to the relay box.

3. Activate each of the Pendant Control buttons and using an AC voltmeter capable of measuring 120VAC, measure the voltage between the appropriate connector pins located in connector CN6 or CN7. See figure 5-7. Polarity of meter test leads is not important. Meter should read 120VAC.

f. Test Results:

If you do not receive the correct meter readings, the relay box or wiring is defective and should be replaced.

NOTE

Before deciding the relay box is defective, check the wires and pins in the connector blocks to make sure they are not loose or making a bad connection with their mate.

5-5. Solenoids

The solenoids are energized by 120 volt potential that is controlled by the relays located inside the relay box.

The solenoid windings are protected from excessive heat with an internal thermal fuse that will open after approximately seven (7) minutes of continuous operation. The solenoid must be replaced if the internal thermal fuse has been blown. The solenoids are mounted directly on either side of the hydraulic mini-valves and push the spool valve in one direction or the other depending upon which solenoid is activated.

WARNING

Line voltage will be measured in this test. Do not touch uninsulated connector pins or meter test leads.

b. Step #1

1. Plug the table cord into the wall receptacle

and turn main switch ON.

2. Disconnect the 2 pin connector from the

solenoid in question. See figure 5-8.

3. Use a voltmeter capable of measuring 120 VAC and measure the voltage across the 2 pin connector. Polarity of meter leads is not important.

NOTE

The appropriate pendant control button must be pushed during this test. The motor will run when this test is performed, and the brake locking solenoid will be activated by any function other than UNLOCK.

c. Test Results:

a. Solenoid Test

The following tests check the voltage applied to the solenoids and the resistance of the solenoid coil.

NOTE

If a solenoid does not function when the pendant control button is pushed, the problem could be the pendant control, the relay box, or the solenoid.

NOTE

Each solenoid is controlled with 120V source coming from the relay box. This source can easily be checked by measuring the voltage at the 2 pin connector in question.

If you do not receive the correct voltage, the problem could be in the wires leading to connectors CN6 and CN7. The problem could also be in the relay box or the Pendant Control (refer to appropriate section for troubleshooting).

If the correct voltage is obtained, everything is good up to that point and the problem is more than likely the solenoid.

d. Step #2

The solenoid can be checked out using an ohmmeter R x 1 scale.

1. Measure the resistance between the two pins of the connector in question. See figure 5-8. Connector being tested must be disconnected. Polarity of meter leads is not important.

2. The meter should read approximately 80-90 ohms at room temperature.

Page 27

3. Measure the resistance between either pin

and ground.

4. Meter should read infinity.

e. Test Results:

If the solenoid does not check out with the meter, it is more than likely defective and must be replaced.

OHM ACV

NOTE

Whenever there are several components of the same type, a defective unit can also be detected by substituting a known good unit or wire connector. In some cases this may be faster than using a multi-meter.

5-6. Motor/Pump Assembly

The electric motor is a capacitor start type with a rating of 120 VAC, 200 watts. The field windings are protected with a thermal protector that will open the winding circuit if the motor is run continuously for approximately 10 minutes. This protector will take about 10 minutes to automatically reset. The oil pump unit is attached to the bottom of the motor and is a gear type displacement pump with a pumping capacity of .4 liter per min. The Motor/ Pump Assembly is mounted on an insulated motor plate in the base of the table. The starting capacitor is mounted along side the motor/pump assembly

a. Motor/Pump Test

The following tests will check the voltage applied to the motor and the resistance of the motor field windings.

c. Test Results:

If you do not receive the correct meter readings, the problem could be in the wires, connectors, relay box, or main switch (refer to appropriate section for troubleshooting).

If the correct voltage is obtained, everything is good up to that point and the problem could be either the motor or the starting capacitor.

d. Step #2

If the starting capacitor is shorted or grounded, the motor will not run. Capacitors very seldom fail, and it requires a dielectric tester to accurately test one. However, an ohmmeter can be used to determine if the capacitor will store a low voltage charge and most of the time this is adequate.

1. Turn the main switch OFF.

Figure 5-9.

2. Connector CN15 should be disconnected.

3. Use the R x 100 scale of the ohmmeter and touch pins 2 and 3 of connector CN15. See figure 5-10.

Page 29

e. Test Results:

The meter needle should move up scale and then back down to infinity. This would indicate that the capacitor is storing an electrical charge.

NOTE

The capacitor may have to be discharged first (by shorting pins 2 and 3 together) before you will be able to see the ohmmeter needle swing up the scale.

f. Step #3

The motor windings can be statically checked for resistance using an ohmmeter.

1. Turn main power switch OFF.

2. Connector CN15 should be disconnected.

3. Use the R x 1 scale of the ohmmeter and measure the resistance between the pins located in the pump connector CN15. See figure 5-11.

5-7. Return-to-Level Micro-Switches.

The return-to-level feature is activated by a single button on the pendant control and automatically levels the major table functions, lateral tilt, trendelenburg, back section, and leg section.

The return-to-level system consists of 6 microswitches, 2 electrical connectors, and the related wiring. The micro-switches are mounted on or adjacent to the function they control and are wired for normally open or normally closed operation. The micro-switches are lever actuated and can be adjusted at the individual switch mounting brackets. See figure 5-12.

The micro-switches operate on low voltage, and control the function circuits (pump/motor and appropriate solenoid valves) when activated by the pendant control RETURN button.

The micro-switches are wired to the relay box through a riser cord and to the 15 pin connector CN2. See figure 5-12 for switch location and identification.

5-8. Troubleshooting

If a problem is suspected in the return circuits, disconnect the connector CN2 from the Relay Box to eliminate the circuits. Ensure that all table functions operate properly using the Pendant Control. If the functions do not work properly using the Pendant Control, refer to the appropriate test section and make all needed repairs before working on the return circuits.
