9 SECTION I GENERAL INFORMATION B. Standard Operation Theory of Operation (See Figures - thru - for wiring diagram / electrical schematic) Electrical power: Line voltage is supplied directly to the table s PC control board. There is a transformer and associated follow-on circuitry on the PC control board which reduces the line voltage to VDC. The VDC provides power to operate the circuitry on the PC control board, foot control, and hand control. Voltage is continuously supplied to the L.H. and R.H. electrical receptacles of VAC units; 0 VAC units do not have receptacles. Manual Operation of Tilt, Back, and Foot Actuator Assemblies: When a function is selected using the hand control, the hand control sends a signal to the PC control board. The signal causes the appropriate relay on the PC control board to energize (i.e., if the TILT UP button is depressed on hand control, the Tilt Up relay on PC control board is energized). Line voltage is continuously supplied to all relays on PC control 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 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 Tilt, Back, and Foot actuators have internal braking mechanisms which use friction to hold the actuator in place. When the actuator is run, the actuator overcomes the force of the friction, allowing it to move. When actuator is stopped, friction stops and holds actuator in place. Manual Operation Of Base Actuator Assembly: When a UP or DOWN function is selected using the hand control, the hand control sends a signal to the PC control board. The signal causes the base up or down relay, and the base brake relay on the PC control board to energize (i.e., if UP button is depressed on hand control, Base Up relay and the base brake relay on PC control board energizes). Line voltage is continuously supplied to the relays on PC control board. So, when the base up or down relay is energized, the line voltage flows thru the relay and is applied across the windings of the actuator motor, causing it to run. At the same time, line voltage flows thru the brake relay and is applied across the solenoid coil of the base brake, causing the brake to disengage. When the hand control button is released, the relays de-energize, removing line voltage from the coils of the actuator motor, causing it to stop and at the same time, removing line voltage from the solenoid coil of the base actuator brake, causing the base brake to engage. The base actuator is different from the other three actuators; it doesn't freewheel at the end of its stroke limit. This is because the base actuator operates under heavier loads. To prevent the base actuator from reaching its stroke limits, which could damage the actuator, two limit switches are used; a base down limit switch and a base up limit switch. These limit switches are normally closed (N.C.) switches. When the base actuator reaches the end of the travel (up or down), the appropriate N.C. switch is tripped, opening the switch circuit. The PC control board detects that the switch circuit has been opened and de-energizes the motor relay and base brake relay, causing the base actuator motor to stop running and the base brake to engage. Headlock Crash Protection Circuit: NOTE The Headlock Crash Protection Circuit section applies to early units only. Later units do not have headlock limit switch or back actuator limit switch. To prevent the headlock assembly from accidentally being run into an object such as a chair, foot, or floor, two limit switches are used. The headlock limit switch, located inside the back weldment, is a normally open (N.O.) switch. However, when the headlock assembly is in its normal position, the limit switch is tripped, creating a closed circuit. The PC control board detects that the circuit is closed and allows all functions to operate normally. If the headlock assembly contacts an object, the mounting bracket of the headlock assembly deflects away from the back assembly; this allows the headlock limit switch to untrip. This creates an open circuit which is detected by the PC control board. The PC control board will not allow the TABLE DOWN, BACK DOWN, and TILT UP functions to run while the headlock limit Midmark Corporation SF- Page - Printed in U.S.A. Rev. /

10 SECTION I GENERAL INFORMATION switch circuit is open (switch is untripped). There is another limit switch called the back actuator limit switch. This limit switch is a N.C. switch which is connected in parallel with the headlock limit switch. If the back actuator limit switch is not tripped, a closed circuit exists which overrides the functionality of the headlock limit switch by bypassing it (allows all functions to run normally even if the headlock limit switch is untripped - an untripped condition exists when headlock mounting bracket is deflected away from back assembly). The back actuator limit switch is tripped when back section is between 0 to 0 above horizontal (in relation to seat section) and untripped when the back section reaches +0. Above +0, the headlock assembly cannot contact the floor and is not needed. Therefore, the back actuator limit switch provides a way of bypassing the headlock limit switch and preventing it from becoming a nuisance (when back section is in full up position, headlock assembly can fall forward due to gravity, which will prevent TABLE DOWN, BACK DOWN, and TILT UP functions from running - a nuisance). Above +0 above horizontal (in relation to seat section), the N.C. back actuator limit switch is untripped creating an closed circuit - at this point the headlock limit switch is bypassed. At +0 or below horizontal (in relation to seat section), the N.C. back actuator limit switch is tripped creating an open circuit - at this point the headlock limit switch is not being bypassed. Pan Safety Limit Switch: The table has a N.O. pan safety limit switch which is monitored by the PC control board. When pan assembly is in stowed position, the switch is tripped resulting in a closed circuit. 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 PC control board detects an open circuit, the foot up relay is disabled, preventing movement of the UP function. This safety feature prevents the table 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 and overheats. The actuator motor is 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 are two /0 amp slow blow fuses (early units use one /0 amp slow blow fuse) providing over-current protection to the input of the PC control board on the non-progrommable table and two 0. amp slow blow fuses providing over-current protection to the input of the PC control board on the programmable table. There is a amp slow blow fuse to provide over-current protection for each function's relays (i.e, Tilt fuse protects TILT UP and TILT DOWN relays). C. Programmable Software Theory of Operation (See Figures - thru - for wiring diagram / electrical schematic) (Applies only to tables with programed positioning) Operation Of Programmable Software: The previous paragraphs have outlined the theory of operation for manual functions on both the programmable and non-programmable tables. The following paragraphs will describe software functions on the programmable tables. When the table is powered up, the software initializes the PC control board and then checks for inputs. There are two inputs which can be initiated by the operator using the hand control; an input to initiate the Calibration function and an input to initiate the Clear Diagnostics Codes function. Also, the PC control board checks if error codes are stored in memory to determine if the error mode should be initiated. Additionally, there are two technician inputs that may be initiated by depressing switches mounted on the PC control board; an input to initiate the Clear Calibration Data function and an input to initiate the Clear Memory function. The Calibration function may be initiated by the technician if a new PC control board or position sensor is installed, the position sensor is adjusted, the table is not moving to a programmed position properly, or the table begins acting erratically. When the calibration mode is initiated, the PC control board runs all actuators to their up and down limits and measures the voltage output of the position sensors at the limits. These voltage values are stored in the PC control board s memory and used as the basis for storing programmed positions into memory. Also, the error codes for incorrect direction and no sensor output change are cleared from the PC control board s memory. If the calibration procedure is Midmark Corporation SF- Page - Printed in U.S.A. Rev. /

11 SECTION I GENERAL INFORMATION not successful due to a position sensor reading being out of limits, the error code indicating why will be stored into the PC control board s memory along with an error code indicating the table is not calibrated. The PC control board emits a second warning beep at. second intervals to indicate to the operator that the calibration procedure is taking place. The calibration procedure is described in Section IV, Maintenance. The Clear Diagnostics Codes function may be initiated by the operator to reset the PC Control Board, after the PC control board initiates the error code mode due to a voltage spike or loose position sensor connection. The PC control board displays the error code by alternately flashing the PROGRAM lamp and the PAN OUT lamp to form a code (See Diagnostic code [error code] operation later in this paragraph). When the table is in the error code mode, only manual positioning of the table will work. To resume normal operation, the Clear Diagnostic Codes procedure must be completed. If the PC control board is replaced or the position sensor is replaced or adjusted, this procedure will not work; in this case, the clear memory procedure followed by the Calibration procedure must be performed. The procedure is described in Section IV, Maintenance. The Clear Calibration Data function is initiated when it is desired to clear the PC control board s memory where the calibration data is stored. The Clear Calibration Data procedure is described in Section IV, Maintenance. The Clear Memory function is initiated when it is desired to clear the PC control board s memory where the error codes and program position data are stored. This function should be used if the PC control board seems locked up or if a position sensor is replaced / adjusted. The Clear Memory procedure is described in Section IV, Maintenance. Operation of Home Position Function: When the operator presses the Home position button, the PC control board lowers the base actuator until the base down limit switch is tripped. The Home position button can be pressed and released; it does not have to be held down to continue movement. If the base down limit switch is not detected as being tripped (open circuit) within seconds from the time the Home position button was pressed, the PC control board de-energizes the base actuator. If the headlock limit switch is detected as untripped, resulting in an open circuit, the PC control board stops the base actuator, terminates the Home position function, and sounds a beep every two seconds. If Base Up function is selected, the base actuator is stopped and the Home position function is terminated. Stop Function Operation: When a Stop button has been pressed, the PC control board terminates all functions, stopping table movement. When the Stop button is released, the stop mode is cancelled and normal table operation may resume. Program Mode Operation: The Program Mode is used to allow the operator to program up to four different table top positions into memory. When the Program Mode button is pressed, the Program Mode function stays active for five seconds, until the operator has pressed one of the four Programmed Position buttons, or the Stop button is pressed. Also, the Program Mode lamp is illuminated and stays illuminated until the seconds are up or an action is taken. When a Programmed Position button is pressed, the PC control board stores the position sensor voltage values for each axis into its memory. Then, if the position was stored correctly, the PC control board flashes the Program Mode lamp three times. Programmed Position Operation: To recall a program that is stored in memory, the operator selects one of the four Programmed Position buttons. The button must be pressed and held to continue table movement. The PC control board determines which direction to run the actuators by comparing the current position sensor voltage output for each axis with the voltage values stored in memory for each axis. The PC control board energizes the relays for the actuators requiring movement and then monitors the position sensor voltage output for each axis. When the position sensor voltage output of each position sensor matches the value stored in the PC control board s memory, the PC control board de-energizes the actuator relays. The PC control board has a maximum run time it allows for each actuator at any one time. This feature prevents damage to an actuator motor because of an actuator relay sticking. When a button is pressed, the PC control board starts a countdown of the maximum time allowed for that actuator. At the end of the countdown, if the button is still sensed by the PC control board as being pressed, the PC control board de-energizes the relay for the actuator. The maximum run time for each function is: Midmark Corporation SF- Page - Printed in U.S.A. Rev. /

12 SECTION I GENERAL INFORMATION Base Up / Base Down - seconds Back Up / Back Down - seconds Foot Up / Foot Down - seconds Tilt Up / Tilt Down - seconds During the Program Position, the PC control board monitors for several errors: If it is detected that a position sensor s voltage is increasing when it should be decreasing, decreasing when it should be increasing, or data input from a position sensor is invalid, the PC control board stops the table and sets an error code condition. An explanation of the error codes is given in para.. If data stored for the Program Position button being pressed is invalid, the Program lamp will flash on and off until the button is released. If the base down limit switch or base up limit switch is tripped (open circuit), the PC control board disables the Program Positioning mode. If the pan safety limit switch is untripped (open circuit), the PC control board disables the Program Positioning mode. If the headlock limit switch (early units only) is untripped (open circuit), the PC control board disables the Program Positioning mode and sounds beep every two seconds (for as long as the headlock is deflected). If the Stop button is pressed, the Program Position mode is disabled. Manual Positioning Software Operation: During manual positioning operation, the software for the programmable table works like the software for the non-programmable table except for some additional controls: If there is invalid data inputs from any position sensor, the PC control board still allows manual positioning operation. If the N.O. pan safety limit switch is untripped (treatment pan is pulled out) (open circuit), the PC control board disables the Foot Up function and illuminates the Pan Out lamp. If conflicting functions are attempted such as Base UP and Base Down, the PC control board disables all functions until all buttons are released. Then, the PC control board resets and normal operation may be continued. Diagnostic Code (Error Code) Operation: When the PC control board detects an error condition, it disables the Home position and Programmed Position functions. When these buttons are pressed, nothing happens at all. By unplugging the table power cord and then plugging it back in, the PC control board enters the diagnostic code mode, described as follows: At power up, if an error code is stored in memory, the PC control board outputs the error code to the hand control in the form of a code. The Program Mode lamp flashes on and then off for the number of times equal to the first digit of the error code stored in memory. Then the Pan Out lamp flashes on and then off for the number of times equal to the second digit of the error code stored into memory. The PC control board then waits one second, repeats the error code a second time, then waits one second and repeats the error code a third time. The next error code is also displayed three times consecutively. This is repeated until all error codes have been displayed. Then, the PC control board continuously displays the error codes on the hand control or foot control. Position Sensor Operation: There is a position sensor mounted to a pivot point on the Back, Tilt, and Foot axis and a position sensor mechanism (called a base reducer assembly) attached to the column assembly for the base function. As each axis rotates / moves, its position sensor s inner wheel rotates with the axis. The position sensor is basically a variable resistor which changes resistance in a linear manner when rotated. So when the axis rotates / moves, the position sensors voltage output changes, due to its resistance change, in a linear fashion based upon how far the axis has moved. The PC control board monitors the voltage change to determine the location of an axis. When a programmed position is programmed by the operator, the PC control board stores the voltage output value of each axis into its memory. When the operator wishes to return to that stored position later, the programmed position button for the desired programmed position is depressed. The PC control board determines the current position of all the axis based on the voltage output of the position sensors for all axis, and then determines which axis must be moved and in what direction. The PC control board energizes the relays for these actuators and the table top is moved to the desired programmed position. The PC control board stops these actuators when the voltage value of the position sensors matches the values stored in the PC control board s memory..

When nothing happens after a Position,,, or button is pressed, perform the following steps to view the error codes on the hand control. A. Using Table s Diagnostic Mode To View Error Codes And Repair Table () Unplug the table power cord from outlet receptacle and wait five seconds before going to next step. NOTE If the PROGRAM MODE lamp does not begin to flash on and off, then the PC control board is not in the error code mode and no error codes will be displayed. () Plug the table power cord into outlet receptacle while observing the PROGRAM MODE and PAN OUT lamps. Observe. The PROGRAM MODE lamp will flash on and then off for the number of times equal to the first digit of the error code stored in memory. Then, the PAN OUT lamp will flash on and off for the number of times equal to the second digit of the error code. Then, the PC control board will pause for one second, repeat the error code a second time, pause one second, and repeat the error code a third time. If there are additional error codes, they are also displayed three time consecutively with a one second pause in between. This is repeated until all error codes in the PC control board s memory have been displayed. Then, the PC control board continuously cycles the error codes on the hand control. () Look up the error code(s) in Table - to get a description of the error code(s). Also, the error code(s) and their remedy(ies) can be found in Table - Troubleshooting Guide. () Once the problem has been repaired, calibrate the table to clear the error codes and allow the table program recall feature to used again (Refer to para.). Error Code Table -.

133 (&,, $ /, 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.. 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.. 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. Always Specify Model & Serial Number Page - Midmark Corporation SF- Printed in U.S.A.
