Manual Use When Damaged Component Is Known. () Replace or adjust component in accordance with maintenance / service instructions (Refer to para.).. Description Of Power Female Procedures Chair A. General Description (See Figure -). The Power Female Procedures Chair is an examination chair designed for performing female specific examinations and procedures on female patients; especially Lithotomy procedures. The major serviceable components of the chair are the seat actuator, seat capacitor, base actuator, base capacitor, gas spring, pan safety limit switch, seat up limit switch, seat down limit switch, base down limit switch, and the foot control which includes four foot switches. B. Theory of Operation (See Figure -, Sheets and for domestic wiring diagrams, Figure -, Sheets and for export wiring diagrams, Figure - for domestic electrical schematic, and Figure - for export electrical schematic.) Electrical Power: Line voltage is supplied directly to the footswitches of the chair. Also, line voltage is always present at the receptacle (domestic units only). Chair Operation: Power is present at all four foot control footswitches. However, the BASE DOWN and SEAT UP switches receive their power thru the BASE UP and SEAT DOWN footswitches, respectively. So, if the BASE UP footswitch is depressed, power is removed from the BASE DOWN footswitch and if the SEAT DOWN footswitch is depressed, power is removed from the SEAT UP footswitch. This wiring setup prevents the operator from trying to run the actuator in an up and down direction simultaneously and causing damage to the actuator. SEAT UP function: When the operator depresses the SEAT UP footswitch, current is applied across the seat actuator motor windings thru the normally open (N.O.) pan safety limit switch and seat capacitor, causing the seat actuator to run. The pan safety limit switch is a N.O switch. When the pan assembly is in its stowed position, the pan safety limit switch is tripped, closing the circuit and allowing the seat actuator to run. If the pan assembly is not in its stowed position, the pan safety limit switch is not tripped, which opens the circuit and prevents the seat actuator from running. This prevents the operator Midmark Corporation 99 SF- Page - Printed in U.S.A.

Major Components from running the foot section into the pan assembly and damaging it. The seat capacitor provides motor start and motor run power for the seat actuator. BASE DOWN function: When the BASE DOWN footswitch is depressed, current is applied across the base actuator motor coil thru either the seat up limit switch or the base down limit switch and base capacitor, causing the base actuator to run. The seat up limit switch is a normally closed (N.C.) switch which is tripped when the seat function is in any position, but all the way up, resulting in an open circuit. This prevents the operator from running the BASE DOWN function (lower than the / up position - see base down limit switch operation) when the seat is in any position, but all the way up, preventing an accidental seat section collision with floor. When the seat function is raised all the way up, the seat up limit switch untrips, closing the circuit, and Midmark Corporation 99 SF- Page - Printed in U.S.A.

7 SECTION I GENERAL INFORMATION allowing the BASE DOWN function to be operated to any position. The base down limit switch is a N.C. switch which is tripped when the base function is between the all the way down position to approximately the / up position, resulting in an open circuit. This means that the switch is untripped only when the base function is in / up position to all the way up position, resulting in a closed circuit. This only allows the operator to lower the BASE DOWN function down to the / up position. Then the base down limit switch trips, opening the circuit, and preventing further downward movement of the base actuator. This prevents an accidental seat section collision with floor. The base capacitor provides motor start and motor run power for the base actuator. So, if the seat up limit switch is tripped (seat function is not in all the way up position), the base down limit switch provides the base actuator with current; this allows you to lower table top only / of way down. But, if the seat up limit switch is untripped (seat function is in all the way up position), the seat up limit switch provides the base actuator with current; this allows you to lower table top all the way down. BASE UP function: When the BASE UP footswitch is depressed, current is applied across the base actuator motor coil and base capacitor, causing the base actuator to run. The base capacitor provides motor start and motor run power for the base actuator. SEAT DOWN function When the SEAT DOWN footswitch is depressed, current is applied across the seat actuator motor coil thru the seat down limit switch and seat capacitor. The seat down limit switch is a N.C. switch which is tripped when the base function is between the all the way down position to approximately the / up position, resulting in an open circuit. This means that the switch is untripped only when the base function is in the / up position to all the way up position, resulting in a closed circuit. This only allows the operator to lower the SEAT DOWN function if the base actuator is in / up position or higher. This prevents an accidental seat section collision with floor. The seat capacitor provides motor start and motor run power for the seat actuator.. Specifications Factual data for the Female Procedures Chair is provided in Table -. Also, see Figure -.

43 . 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 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 99 SF- Page - Printed in U.S.A.
