Prior to use, all personnel that may operate thistable must be instructed in the correct opera-tional procedures. This table is designed foruse by trained and qualified personnel for hu-man medical purposes only.

Initial use should not begin until after the usershave been instructed by the manufacturer'srepresentative.

A routine instructional program must be imple-mented by the facility for proper usage instruc-tions for all personnel that may operate thistable.

The maximum lifting capacity of the 1700 Tableis 500 pounds and the maximum articulationweight capacity is 500 pounds. When lifting orarticulating large patients, pay close attention tothe patient position as well as the positioningguidelines and limitations listed in the opera-tion instructions.

The extreme positioning capabilities of the 1700Table requires special attention for possible inter-ference points when using multiple function posi-tioning. As with the operation of any surgical table,a certain amount of care should be exercised toposition the patient safely. Although the thick padsand sheets substantially protect the patient, pinchpoints, located at the joints of the top section shouldalways be considered. BE SURE THAT THEARMS, HANDS AND FINGERS OF THE PA-TIENT AND THOSE OF THE OPERATINGROOM PERSONNEL ARE CLEAR OF ALL MOV-ING PARTS BEFORE MOVING THE TABLE.Proper restraints should always be used for patientsafety.

Certain accessories such as the Armboards andTable Side Extensions can be damaged whenchanging the position of the table top sections.Always look first to see if a desired movement isgoing to interfere with any accessories in use.

The operator has the ultimate responsibility ofpreventing damage to the table and surroundingequipment or possible injury to the patient or staff.

The operator must ensure proper positioning ismaintained to prevent compromising respiration,nerve pathways or circulation.

In general, common sense will dictate when thereis a potential hazard.

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

WARNING

1-1. General

Electro-Hydraulic System

The hydraulic system (with the exception of thehydraulic cylinders and hoses) is contained withinthe base of the table. The hydraulic valves andpump are electrically controlled by the use of ahand-held push button pendant control. The powerrequirements for the table are 120 VAC, 5 amp, 60Hz.

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

a. Oil Reservoir - Main oil supply. Approximatelytwo quarts.

b. Motor/Pump Assembly - A positive displace-ment gear type pump provides the necessary oilpressure and volume.

c. Pressure Relief Valve - Provides an alternate oilpath when the hydraulic cylinders reach the end oftheir stroke.

d. Electro/Hydraulic Mini-Valve Assemblies -Thesedirect the fluid to the appropriate hydraulic cylinders.

e. Hydraulic Lines, Fittings, Connections - Theyprovide a path for the hydraulic oil.

f. Hydraulic Cylinders - They convert the hydraulicfluid pressure and volume into mechanical motion.

1-2. Component Operation

a. Motor/Pump Operation

The motor/pump assembly is a positive displace-ment gear type pump that provides the oil pressureand volume for the entire hydraulic system. Thepump has an inlet side and an outlet side. The inletside is connected to the reservoir which providesthe oil supply.

The output line of the pump is connected to themain oil galley which is internal and common to allthe hydraulic mini-valves and pressure relief valve.Also, common to the hydraulic mini-valves andpressure relief valve is an oil galley that internallyconnects to the oil reservoir to provide a return pathfor the hydraulic oil. See figure 1-2.

Figure 1-4. Pressure Relief Valve Functioning

Figure 1-3. Pressure Relief Valve NotFunctioning

b. Pressure Relief Valve

This device provides an alternate oil path when thehydraulic cylinders reach the end of their strokeand the pump continues to run. If this path were notprovided, the pump motor would stall because theoil cannot be compressed. The pressure reliefvalve is directly connected to the mini-valve bodiesand shares both the common internal main pres-sure oil galley, and the return oil galley, that inter-nally connect to the reservoir. See figure 1-3.

Figure 1-2.

The main component of the valve is an adjustablespring loaded plunger that is pushed off from itsseat by the oil pressure. The oil then flows back intothe reservoir. See figure 1-4. Turning the adjust-ment nut clockwise increases the amount of oilpressure required to open the valve, and turning itcounterclockwise decreases the amount of oil pres-sure. (See adjustment section for specification.)

c. Mini-Valves

The operation of the mini-valves is identical for alltable functions except the elevation and brakecircuits. These two hydraulic circuits use a 3-way(single check valve) type mini-valve. All other func-tions use a 4-way (dual check valve) type mini-valve.

Either type mini-valve is controlled by two pushingtype, electrically operated solenoids. The sole-noids push the spool valve (located in the lowerportion of the valve) one way or the other. Thismotion opens the main supply galley (which haspump pressure) allowing the oil to flow through thevarious parts of the mini-valve to the function. Thespool valve also opens an oil return circuit whichallows the oil to return to the oil reservoir.

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

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

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

3. Check Valve - Two are provided in each four-way mini-valve to seal the oil in the cylinders and oillines and prevent any movement of the table. Onecheck valve is provided in a 3-way mini-valve.

4. Speed Adjustments - There are two speedadjustments in each mini-valve. They are needlevalve type controls which restrict the volume of oilreturning back into the reservoir, thereby control-ling the speed of the table surface movement. A 3-way mini-valve has only one speed adjustment.

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

Also, by using this control method, it doesn’t matterwhat size cylinder and piston is used because thespeed can be controlled by restricting the return oil.If the pump puts out more volume to a certain slavecylinder than the speed control is allowing to goback to the reservoir, the pressure relief valveprovides 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 bothoil pressure and oil return galleys.

2. Pilot Plungers Both Closed -The pilot plung-ers control the opening of the check valves. If theyare closed, the check valves must be closed.

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

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

f. Mini-Valve Left Port Activated(See figure 1-7.)

Slave Cylinder Piston Moves to RightLeft Mini-Valve Port is Supply LineRight Mini-Valve Port is Return Line

1. Spool Valve - Pushed to the left by electricsolenoid. This opens the internal oil pressure gal-ley allowing the fluid to go through the check valveand on to the cylinder. Also, the spool valve opensthe oil return line providing an oil path through theinternal oil galley back to the reservoir.

2. Pilot Plunger Valve - Left pilot plunger valveis pushed up by the incoming oil pressure mechani-cally opening the check valve located above it in thereturn circuit. This action allows the oil from the leftside of the slave cylinder to go back into thereservoir. The right pilot plunger valve is notaffected in this operation mode.

3. Check Valves - Both check valves areopened in this operation mode. The right checkvalve is pushed open by the oil pressure created bythe pump. The oil then continues to go through thelines and pushes the slave cylinder piston to theleft. At the same time, the left check valve is heldopen mechanically by the pilot plunger providing areturn path for the oil through the mini-valve backto the reservoir.

4. Speed Adjustment - The right speed control(output side) does not have any effect in thisoperation mode because the oil is routed aroundthe speed adjustment through a by-pass valve andthen to the output port. The left speed adjustmentcontrols the speed of the table function by restrict-ing the amount of oil going back into the reservoir.

1. Spool Valve -Pushed to the right by electricsolenoid. This opens the internal oil pressure galleyallowing the fluid to go through the check valve andon to the cylinder. Also, the spool valve opens theoil return line providing an oil path through theinternal oil galley back to the reservoir.

2. Pilot Plunger Valve - Right pilot plunger valveis pushed up by the incoming oil pressure mechani-cally opening the check valve located above it in thereturn circuit. This action allows the oil from theright side of the slave cylinder to go back into thereservoir. The left pilot plunger valve is not affectedin this operation mode.

3. Check Valves - Both check valves are openedin this operation mode. The left valve is pushedopen by the oil pressure created by the pump. Theoil then continues to go through the lines andpushes the slave cylinder piston to the right. At thesame time, the right check valve is held openmechanically by the pilot plunger providing a returnpath for the oil through the mini-valve back to thereservoir.

4. Speed Adjustment - The left speed control(output side) does not have any effect in this oper-ation mode because the oil is routed around thespeed adjustment through a by-pass valve andthen to the output port. The right speed adjustmentcontrols the speed of the table function by restrict-ing the amount of oil going back to the reservoir.

2. Trendelenburg Cylinder Assembly - TheTrendelenburg and Lateral Tilt cylinders share acommon housing. The Trendelenburg assemblyconsists of two pistons and connecting rods thatconnect to a stationary pin on the Trendelenburgpivot casting which is attached to the center col-umn. The cylinder housing is attached to the tabletop and connects to the pivot casting with an axispin. When hydraulic fluid is pumped into onecylinder, the cylinder housing itself moves aroundthe pivot housing causing the table top to tilt. Areturn path is opened for the hydraulic fluid of theother piston. See figure 1-10.

g. Hydraulic Cylinders (Slave Cylinders)

There are several different types of hydraulic cylin-ders used in the table that activate the controlfunctions, all operate basically the same way. Thecontrol functions are listed below: (See figure 1-8.).

Figure 1-8. Cylinder Placement

1. Back Section and Leg Section Cylinders - Thedouble action cylinders are closed at one end andhave a movable piston with hydraulic fluid on bothsides. Connected to this piston is a ram that exits outof the other end of the cylinder. Through the use of aclevis and pin arrangement, this ram is connected toa movable table surface.The movable surface can be moved one way or theother by pumping hydraulic fluid into the cylinder oneither side of the piston. A return path is opened forthe oil on the other side. See figure 1-9.

Figure 1-10. Trendelenburg Cylinder Assy.

3. Lateral Tilt Assembly - The lateral tilt assemblyconsists of two pistons and connecting rods. Theconnecting rods attach to the table top frame.When hydraulic fluid is pumped into one cylinder,the piston and connecting rod tilts the table top toone side. To tilt the table top in the oppositedirection, fluid is pumped into the opposite cylinder.See figure 1-11.

4. Elevation Cylinder - This single action cylin-der does not have hydraulic fluid on both sides ofthe piston. It depends on the weight of the table topassembly to lower it.The cylinder is set in the center of the elevationmain column. The cylinder is elevated by the drivenforce of the oil pressure. When lowering, the oil thatis accumulated in the cylinder is returned to the oilreservoir through the mini-valve due to the table topweight.A slider support assembly is used to support theweight of the upper table section. A stainless steelshroud covers the flexible hydraulic hoses andslider. See figure 1-12.

Figure 1-12. Elevation Cylinder Assembly

5. Brake Cylinders - The brake cylinders aresingle action type similar to the elevation cylinder.The movable piston's ram is connected to a brakepad. See figure 1-13. Oil pumped into the top of thecylinder pushes the piston down raising the tablebase off its casters. An internal return spring on thebottom of the piston, pushes the piston up to returnthe oil through the mini-valve to the reservoir.

Figure 1-13. Single Action Brake Cylinder

h. Elevation Cylinder Return Circuit

Three-way (single check valve type) mini-valvescontrol both the elevation and return circuits. Theelevation circuit operation within the mini-valve isidentical to the operation of the four-way valvespreviously described. In the return position, inletpressure pushes the pilot plunger up and opens thereturn check valve. See figure 1-14. The opencheck valve allows a path for the oil in the elevationcylinder to return to the reservoir. When the pilotplunger valve is opened, the continuing pump pres-sure opens the pressure relief valve which pro-vides a return oil path to the reservoir.

The mini-valve contains only one check valve whichis used to trap the oil in the elevation cylinderthereby supporting the table top. When the top islowered the check valve is mechanically held openby the pilot plunger through pump pressure.

i. Brake System

The brake system consists of the following compo-nents: (figure 1-15)

1. Single action slave cylinders (4 each).2. 3-way (single check valve type) mini-valve.3. Manually controlled emergency brake re-

lease.4. Plumbing terminal, flexible hoses, copper

lines and "O" rings.5. Portions of the electrical system.

Each corner of the cast-iron table base has ahydraulic brake cylinder. These single action cyl-inders are hydraulically connected in parallel to themini-valve and all four are activated together. It isnormal for one corner of the table to raise before theothers due to the weight distribution of the table.

An electronic timer in the relay box is activatedwhen any function on the pendant control ispushed momentarily. The pump/motor and brakesystem mini-valve are activated and the brakecylinders are completely set. The electronic timerruns for approx. 8-10 seconds.

The brakes are released by pushing the BRAKEUNLOCK button momentarily. An electronic timerin the relay box activates the brake function hy-draulic mini-valve and pump/motor.

When activated, the return hydraulic circuit oper-ates similar to the elevation cylinder return circuit.Return springs inside the single action brake cylin-ders retract the brake pads and provide the pres-sure to return the hydraulic oil back to the reservoir.The electronic timer operates the return circuit forapproximately 8-10 seconds.

j. Emergency Brake Release

The emergency brake release is simply a manuallyoperated bypass valve connected in parallel to thebrake cylinders and the oil reservoir. See figure 1-16. When the valve is opened (turned counter-clockwise) a return circuit for the brake hydraulicfluid is opened. The return springs force thepistons up pushing the hydraulic oil back into thereservoir and retracting the brake pads.

Figure 1-15. Brake System Block Diagram

Figure 1-16.

NOTE

•The emergency brake release valvemust be tightened securely when not inuse.

•If the emergency brake release valvehas been operated, the UNLOCK but-ton on the pendant control may have tobe pressed before brakes will lock again.

If the emergency brake release valve is open orloose, the brakes will release slowly- depending onhow loose the valve is, this could take anywherefrom a few minutes to several hours.

2. Raise the table top until the piston reachesthe end of its stroke and stalls. Observe reading onpressure gauge and turn the adjustment nut (clock-wise to increase oil pressure, counterclockwise todecrease) until desired reading is obtained. Pres-sure should be 80KG/CM† -1138 PSI.

Figure 1-17.

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

b. Bleeding The Hydraulic System

To purge the air from the hydraulic system, operateeach function back and forth at least two or threetimes.

NOTE

Whenever a hydraulic line or compo-nent is replaced, bleed the air out of thelines using the pump pressure beforemaking the final connection. Then op-erate the function until it stalls in bothdirections.

1-3. Hydraulic Adjustments

a. Fluid Level.

The fluid level should be approximately 1/2" belowthe filler hole or gasket surface. If additional fluid isneeded, remove the filler vent cap with a phillipsscrewdriver and add fluid through this openingusing a funnel. See figure 1-17.

NOTE

The elevation cylinder should be com-pletely down and all the other controlfunctions in their neutral position whenchecking oil level.

c. Pressure Relief Valve

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

To adjust:

1. Remove the blind cap and attach a hydraulicpressure gauge to the main oil galley using a 6mmplumbing bolt. See figure 1-18.

Use the second hand on a watch and timea particular function. Match that time in the oppo-site direction by opening or closing the speedcontrol. Approximate operating times are as fol-lows:

Lateral Tilt 5 secondsBack Up 13 secondsBack Down 5 seconds

d. Speed Controls

The speed controls restrict the volume of oil return-ing back to the reservoir thereby controlling thespeed of each control function.

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

One speed control adjusts one direction of aparticular function and the opposite speed controladjusts the other direction. They are adjustable byusing a small straight blade screwdriver andturning the adjustment screw clockwise to de-crease the speed and counterclockwise toincrease the speed. Refer to figure 1-19.

SECTION II HYDRAULIC TROUBLESHOOTING

2-1. PrecautionsBefore attempting to troubleshoot any hydraulicproblem on the table, please read through the pre-cautions and notes below.

CAUTION

When disconnecting any of the hydrau-lic lines, fittings, joints, hoses, etc., forthe following control functions, be surethese table surfaces are in their downposition or completely supported.

•Elevation•Back Section•Leg Section

When working on the Trendelenburgor lateral tilt hydraulic circuits, be sureto support the table top. When workingon the brake system make sure thebrakes are completely retracted.

WARNING

Failure to follow these precautions mayresult in an uncontrolled oil spray anddamage to the table or personal injury.

2-2. Troubleshooting Notes

When troubleshooting a table malfunction, firstdetermine the following:

1. Does the problem affect all control func-tions?

2. Does the problem affect only one controlfunction?

3. If the problem affects one control function isit in both directions?

4. Is the problem intermittent?

5. Is the problem no movement of a tablesurface or does the table surface lose position?

Once the problem has been determined, concen-trate on that particular hydraulic circuit or controlfunction.

Listed below are the hydraulic components thatare common with all hydraulic circuits. If there is aproblem with any of them, it could affect all controlfunctions.

1. Motor/Pump Assembly2. Reservoir3. Pressure Relief Valve4. Certain Oil Lines and Galleys

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

1. Mini-Valve2. Slave Cylinder3. Oil Lines

NOTE

Whenever a hydraulic line or compo-nent is replaced, bleed the air out of thelines using the pump pressure beforemaking the final connection. After allconnections are tight, cycle the controlfunction back and forth two or threetimes to purge the remaining air fromthe system.

CAUTION

When installing new "O" rings use whitelithium grease or hydraulic oil to thoroughlylubricate the "O" rings and cylinder. Keepeverything clean.

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

4-1. Troubleshooting Notes

The basic operation of each component will bedefined along with a drawing and explanation onhow to check it out.

Certain defective components could cause theentire table to stop functioning or only one controlfunction to stop. It would depend on what part of thecomponent failed. Other defective componentswould only cause one control function to stop.

The following defective components could causeall control functions to be affected:

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

The following defective components could causeall control functions to be affected or only onecontrol function:

a. Relay Boxb. Pendant Control

The component listed below would only affect onecontrol function:

Solenoid

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

4-2. Main Switch

The main power supply, 120 VAC, 60 HZ, comes inthrough the power cord and through the mainswitch. The main switch opens both lines when inthe "OFF" position. Two 10 amp fuses are used toprotect the complete electrical system and arelocated next to the main switch.

a. Main Switch Test

The following test will determine if line voltage isapplied to connector CN4, which in turn wouldpower the table.

1. Plug the power cord into the 120VAC powersupply (wall receptacle) and turn ON the mainswitch.

2. Disconnect connector CN4 from the relaybox. See figure 4-1. Leave all other connectorsconnected.

SECTION IV ELECTRICAL SYSTEM TROUBLESHOOTING

Figure 4-1. Main Power Test

CAUTION

Line voltage (120 VAC) will be mea-sured in this test. Do not touch uninsu-lated connector pins or meter test leads.

3. Use an AC voltmeter capable of measuring120 VAC and measure the voltage between pins1 and 2 (black and white wires) located in connectorCN4. See figure 4-2. You should receive linevoltage 120 VAC.

b. Test Results

If you do not receive the correct voltage measure-ment, the problem would have to be in the wires,main switch, fuses, or power cord. If the correctvoltage is obtained, everything is good up to thispoint and the problem would have to be in anotherarea.

4-3. Pendant Control

The Pendant Control is part of the solid state, multi-plex, logic control system. The pendant controlcontains illuminated, circuit board mounted switchesand a micro processor. The encoded output from thependant control is serial bit stream logic.

The output signal is transmitted to the micro pro-cessors in the relay box where the logic is decodedand the appropriate relays for the selected functionare activated.

a. Wiring Harness TestThe following test checks the wires leading from thetable connector to connector CN7 at the Relay Box.Disconnect connector CN7 from the Relay Box andusing an ohmmeter, test the continuity between thecorresponding pins in connectors CN7 and thetable connector. See figure 4-3.

is always activated no matter what control functionis selected. The brake locking circuit relay is alsoactivated when any control function other thanBRAKE UNLOCK is initially selected.

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

The following tests will determine if the relay box isfunctioning correctly.

a. Checking Relay Box Connector CN4

1. Connect the power cord to the table. Plugthe power cord into the 120 VAC power supply (wallreceptacle) and turn the main switch ON. Leave allconnectors connected.

WARNING

Line voltage (120 VAC) will be mea-sured in this test. Do not touch uninsu-lated connector pins or meter test leads.

2. Use an AC voltmeter capable of measuring120 volts and measure the voltage between pins 1(white) and 2 (black) of connector CN4 for inputvoltage. See figure 4-4. Meter should read linevoltage 120 VAC.

3. Activate any table function with the PendantControl and using an AC voltmeter, test the voltageat pins 3 and 4 of CN4 for output to the pump. Metershould read 120 VAC.

4-4. Relay BoxThe 120 volt power supply is directly connected tothe relay contacts. When these contacts areclosed, 120 volts is supplied to the solenoids whichare mounted on the hydraulic mini-valves. Onerelay is used to supply 120V to the pump/motor and

Page 22

b. Test Results:

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

c. Checking Output to Solenoidshis test checks the high voltage (120V) that is usedto energize the solenoids.

WARNING

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

NOTE•The Brake Lock function is activatedby pressing any function button (exceptBRAKE UNLOCK). A timer in the RelayBox allows continuous output for about7 seconds. If the brakes are alreadylocked, no output is provided.

•The BRAKE UNLOCK button activatesanother timer in the relay box whichallows continuous output for the brakerelease function for approximately 7seconds. If the brakes are released(using the BRAKE UNLOCK button) nooutput is provided.

1. The power cord should be plugged into thewall receptacle and Power Switch turned ON.

2. Disconnect the motor connector. All otherconnectors should be connected. Test connectorsCN1, CN2A and CN2B from the back while at-tached to the relay box.

3. Activate each of the Pendant Control buttonsmeasure the voltage for the corresponding con-nector pins with an AC voltmeter. See figure 4-5.Meter should read 120VAC.

d. Test Results:

If you do not receive the correct meter readings, therelay box or wiring is defective and should bereplaced.

NOTE

Before deciding the relay box is de-fective, check the wires and pins in theconnector blocks to make sure they arenot loose or making a bad connectionwith their mate.

Figure 4-5. Solenoid Output Connectors

e. Checking Output to Pendant Control

The output to the Pendant Control can not be testedwithout specialized equipment. If all tests havebeen conducted and it appears that the Relay Boxis faulty, contact SKYTRON.

4-5. Solenoids

The solenoids are energized by 120 volt potentialthat is controlled by the relays located inside therelay box.

The solenoid windings are protected from exces-sive heat with an internal thermal fuse that will openafter approximately seven (7) minutes of continu-ous operation. The solenoid must be replaced ifthe internal thermal fuse has been blown. Thesolenoids are mounted directly on either side of thehydraulic mini-valves and push the spool valve inone direction or the other depending upon whichsolenoid is activated.

c. Test Results:

If you do not receive the correct voltage, the prob-lem could be in the wires leading to connectors.The problem could also be in the relay box or thePendant Control (refer to appropriate section fortroubleshooting).

If the correct voltage is obtained, everything isgood up to that point and the problem is more thanlikely the solenoid.

d. Step #2

The solenoid can be checked out using an ohm-meter R x 1 scale.

1. Measure the resistance between the twopins of the connector in question. See figure 4-6.Connector being tested must be disconnected.Polarity of meter leads is not important.

2. The meter should read approximately 60ohms at room temperature.

3. Measure the resistance between either pinand ground.

4. Meter should read infinity.

e. Test Results:

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

NOTE

Whenever there are several compo-nents of the same type, a defective unitcan also be detected by substituting aknown good unit or wire connector. Insome cases this may be faster thanusing a multi-meter.

a. Solenoid Test

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

NOTE

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

NOTE

Each solenoid is controlled with 120Vsource coming from the relay box. Thissource can easily be checked by mea-suring the voltage at the 2 pin connec-tor in question.

WARNING

Line voltage will be measured in thistest. Do not touch uninsulated connec-tor pins or meter test leads.

b. Step #1

1. Plug the table cord into the wall receptacleand turn main switch ON.

2. Disconnect the 2 pin connector from thesolenoid in question. See figure 4-6.

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

NOTE

The appropriate pendant control but-ton must be pushed during this test.The motor will run when this test isperformed, and the brake locking sole-noid will be activated by any functionother than UNLOCK.

c. Test Results:

If you do not receive the correct meter readings, theproblem could be in the wires, connectors, relaybox, or main switch (refer to appropriate section fortroubleshooting).

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

d. Step #2

If the starting capacitor is shorted or grounded, themotor will not run. Capacitors very seldom fail, andit requires a dielectric tester to accurately test one.However, an ohmmeter can be used to determineif the capacitor will store a low voltage charge andmost of the time this is adequate.

1. Turn the main switch OFF.

2. Motor connector should be disconnected.

3. Use the R x 100 scale of the ohmmeter andtouch pins 2 and 3 of the connector. See figure 4-8.

4-6. Motor/Pump Assembly

The electric motor is a capacitor start type with arating of 120 VAC, 200 watts. The field windingsare protected with a thermal protector that will openthe winding circuit if the motor is run continuouslyfor approximately 10 minutes. This protector willtake about 10 minutes to automatically reset. Theoil pump unit is attached to the bottom of the motorand is a gear type positive displacement pump witha pumping capacity of .4 liter per min. The Motor/Pump Assembly is mounted on an insulated motorplate in the base of the table. The starting capacitoris mounted along side the motor/pump assembly

a. Motor/Pump Test

The following tests will check the voltage applied tothe motor and the resistance of the motor fieldwindings.

CAUTION

Line voltage will be measured in thistest. Do not touch uninsulated connec-tor pins or meter test leads.

b. Step #1

1. Plug the power cord into 120 VAC powersupply (wall receptacle). Turn main switch ON.

2. Disconnect the 3 pin motor connector at themotor. Leave all other connectors connected. Seefigure 4-7.
