Manual Use When Damaged Component Is Known. () Replace or adjust component in accordance with maintenance/service instructions (Refer to para.).. Description Of Power Examination Table A. General Description (See Figure -). The major serviceable components of the table are the headlock, back actuator, back transmitter, back receiver, back capacitor, foot actuator, foot transmitter, foot receiver, foot capacitor, tilt actuator, tilt transmitter, tilt receiver, tilt capacitor, base actuator, base transmitter, base receiver, base capacitor, base down limit switch, chain assembly, base slide assembly, gas spring(s), program panel, program panel interface board, PC logic board, interface board, hand control panel, hand control PC board, foot control foot switches, and pan safety limit switch. B. Theory of Operation (See Figures - and - for wiring diagrams / electrical schematics) Electrical Power: Line voltage ( VAC for domestic units and 0 VAC for export units) is supplied directly to the table's interface board. There is a transformer and associated follow-on circuitry on the interface board which reduces the line voltage to - VDC. The - VDC provides power to operate the circuitry of the PC logic board, hand control, and foot control. On domestic units, VAC is continuously supplied to the electrical receptacle. Export units do not have an electrical receptacle. Manual Operation of Base, Tilt, Back, and Foot Actuator Assemblies: When a manual function is selected using the manual positioning buttons on the hand control or program panel, a signal is sent thru the PC logic board to the interface board. The signal causes the appropriate relay on the interface board to energize (i.e., if the TILT UP button is depressed on hand control, the Tilt UP relay on interface board is energized). Line voltage is continuously supplied to all relays on interface board. So, when a relay is energized, the line voltage flows thru the relay and is applied across the windings of the actuator motor, causing it to run. When the hand control button is released, the relay de-energizes, removing the line voltage from the windings of the actuator motor and causing it to stop running. The Power Examination Table is an examination table designed specifically for performing general medical examinations and procedures. Midmark Corporation SF- Page - Printed in U.S.A.

FOOT CONTROL FOOT SWITCH MA000 Figure -. Major Components Midmark Corporation SF- Rev. / Page - Printed in U.S.A.

9 SECTION I GENERAL INFORMATION Actuator Operation: The Base, Tilt, Back, and Foot actuators are ball screw driven. The actuator assemblies contain a pivot point on the end of the ball screw. If an actuator assembly is run to the end of its stroke, the ball screw shaft spins inside the nut, which allows the actuator assembly to run without damaging or advancing the nut. The Base, Tilt, Back, and Foot actuators have internal braking mechanisms which use a friction device to keep actuator stationary when the actuator is not being run. Programming Operation: The model can be programmed for up to eight operator specified positions. To program a position into memory, the operator uses the manual positioning buttons on the hand control or program panel to position the table top in the desired position. Now, the PC logic board determines the position of each function as follows: each actuator has a transmitter and a receiver attached to it; the receiver is mounted to the motor end of the actuator and is stationary while the transmitter is mounted to the moving actuator shaft of the actuator. The PC logic board has the transmitter on each actuator shaft continuously transmit a high frequency sound wave which is received by its receiver. The PC logic board compares the transmit point on the wave form against the receive point on the wave form and uses this data to determine the distance between the transmitter and receiver for each actuator. The PC logic board uses this frequency measuring technique to determine the position of the actuators at all times. The operator now presses the PROGRAM button followed by one of the eight PROGRAMMED POSITION buttons. The red L.E.D. under the PROGRAM button will illuminate when the PROGRAM button is pressed and will remain illuminated for four seconds to inform the operator that he / she may now select a PRO- GRAMMED POSITION button ( thru ). After four seconds, the PROGRAM function will automatically disable itself if a PROGRAMMED POSITION button has not been selected. When a PROGRAMMED POSITION button is pressed, the receive point on the wave form for each actuator is stored into memory. Now the operator can easily return to the position stored in memory. To do so, the operator presses and holds the PROGRAMMED POSITION button ( thru ) which has the desired position stored in memory. The PC logic board compares the receive point on the wave form that is actually being measured by each actuator's transmitter / receiver set, against the value stored in the PC logic board's memory. The PC logic board then energizes the appropriate relays and allows each actuator to run until the receive point on the wave form being measured by each actuator's transmitter / receiver set is equal to the value stored in the PC logic board's memory. When the values are equal, the relays are de-energized, stopping the actuators. Auto Return Operation: When the operator presses the AUTO RETURN button, the PC logic board energizes the base actuator's down relay, causing the base actuator to run. The base actuator lowers until the base down limit switch is tripped. The PC logic board also senses that the base down limit switch is tripped and de-energizes the base actuator relays. If the operator, at any time, wishes to stop the auto return function, he / she can press the STOP button. The PC logic board senses that the STOP button has been pressed and de-energizes the base actuator relays, causing the base actuator to stop. Pan Safety Limit Switch: The table has a N.O. pan safety limit switch. If the pan assembly is not pushed into its fully stowed position, the pan safety limit switch will not be tripped and there will be an open circuit. If the pan safety limit switch circuit is open, no power can reach the foot actuator windings, preventing movement of the FOOT UP and FOOT DOWN function. This safety feature prevents the operator from accidentally colliding the foot section into the treatment pan assembly. General Information: All actuator motors have a thermal overload switch which will activate if the actuator assembly is run continuously. The actuator motor was not designed for continuous operation. The normal cool off period for the thermal overload switches is 0-0 minutes. Each actuator motor has a capacitor which provides start up power and motor run power. There is a 0. amp fuse, located on the interface board, which provides over-current protection for the transformer. Midmark Corporation SF- Rev. / Page - Printed in U.S.A.

10 SECTION I GENERAL INFORMATION There are four amp slow blow fuses, located on the interface board, which provide over-current protection for each function's motors (i.e, Tilt fuse protects tilt actuator motor). Under the control console, there is an ON / OFF switch. Turning the switch to OFF disables movement of the table, preventing accidental table movement or patients from operating table. A red CONTROL PANEL POWER L.E.D. illuminates when the ON / OFF switch is in the ON position.. Specifications Factual data for the Power Examination Table is provided in Table -. Also, see Figure -.

67 SECTION VI PARTS LIST. Introduction The illustrated parts list provides information for identifying and ordering the parts necessary to maintain the unit in peak operating condition. Refer to paragraph. for parts ordering information. The parts list also illustrates disassembly and assembly relationships of parts.. 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. SECTION VI PARTS LIST 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.. 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. Midmark Corporation SF- Page - Printed in U.S.A.
