GENERAL INFORMATION

Table Operation using Hand Control: When a hand control button is pressed, the hand control

sends serial digital signals to the PC control board using two data lines. (Early units sent PC board using determines which function was selected by analyzing which data lines contained a signal and then the PC control board energizes the relay for the selected function.

There is always line voltage potential at the output of the relays; there is a relay for each up and down function: BASE UP, BASE DOWN, BACK UP, and BACK DOWN. So, when a relay is energized closing the circuit, line voltage is applied across the relay and then across the motor coil of the selected function, causing it to run. When the hand control button is released, the function's relay is de-energized, removing line voltage from the motor coil which causes it to stop running. The BASE DOWN function has an additional control circuit (the base down limit switch) to prevent the base actuator from freewheeling at the end of its down travel. The base down limit switch is adjusted to trip just before the base actuator is completely lowered. When the N.O. base down limit switch is tripped closing the circuit, the PC control board de-energizes the base down relay causing the base actuator to stop running (even if the hand control button is still being depressed by the operator). This prevents the base actuator from freewheeling when it reaches the end of its down travel. Otherwise, under heavy loads, excessive wear or damage to base actuator could result.

When the AUTO RETURN button is depressed, the PC control board energizes the BASE DOWN relay; the BASE DOWN function will continue to run even if the operator releases the button. The PC control board also monitors the status of the normally open (N.O.) base down limit switch. The N.O. base down limit switch is not tripped, resulting in an open circuit, when the actuator is in all positions but its auto return home position (base down completely lowered). When the base actuator reaches its auto return home position, the base down limit switch is tripped, closing the circuit. The PC control board senses this and de-energizes the relay for the base down function causing the base actuator to stop. When the base down limit switch has tripped, stopping the base down actuator, the auto return function is complete. The PC control board has a backup timing circuit in case the base down limit switch malfunctions during the auto return function. If the PC control board does not see the status of the base down limit switch change within approximately 17 seconds of

three

data lines). The PC control board

analog

signals to the

actuator run time, the backup circuit shuts down the auto return function. The STOP button may be pressed at any time during the AUTO RETURN function. When the STOP button is pressed, the PC control board stops the auto return function. This de-energizes the base down relay, stopping the base actuator.

Actuator Operation: The base and back 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 (called freewheeling).

The base and back actuators have internal braking mechanisms which disengage when the motor starts running and engage when the motor stops running.

Foot Control Operation The foot control used on later units sends serial digital signals to the PC board using two data lines. The PC board determines which function was selected by analyzing which data lines contained a signal and then energizes the relay for the selected function. The foot control used on early units sends a signal from a footswitch in the foot control to the PC board thru a line which does not require any decoding.

Optional Heater Plate Some units are equipped with the optional heater plate. When the operator turns the (N.O.) HEATER ON / OFF switch to ON, closing the circuit, power is supplied to the heater plate, heating the unit. This provides heat in the top, foot end drawer to warm instruments.

• There are three Data Line L.E.D.'s; data line #1

L.E.D., data line #2 L.E.D., and data line #3 L.E.D.. Different combinations of these L.E.D's

illuminate to indicate if the proper input signal is being sent to the PC control board from the mem-

brane panels or hand control. General Information: All actuator motors have a thermal overload switch

which will activate if the actuator assembly is run continuously, causing its motor to overheat. The actuator motors are not designed for continuous operation. The normal cool off period for the thermal overload switches is 10 - 20 minutes.

Each actuator motor has a capacitor which provides start up power and motor run power.

There are two 0.10 amp fuses ( one 0.25 amp fuse on early units) , located on the PC control board, which provide over-current protection to the control circuitry of the PC control board.

There are two 5 amp slow blow fuses, located on the PC control board, which provide over-current protection for each function's motor (i.e, Base fuse protects base actuator motor).

On early units, there is board labeled SW1 (this switch must be in the IN position to bypass the back up limit switch which is not used on this unit) or a jumper connector across both SW1 pins (this jumper connector must be installed on both SW1 pins to bypass the back up limit switch which is not used on this unit). This prevents the back function from moving when the auto return function is selected. Later units with Serial Numbers LE1000, LF1000 and LG1000 thru Present use a new style PC board and do have the SW1 switch.

• The base down relay L.E.D. illuminates to indicate that the PC control board is energizing the base down relay.

• The foot control back up L.E.D. illuminates to indicate that the PC control board is receiving a good signal from the back up foot switch.

• The foot control back down L.E.D . illuminates to indicate that the PC control board is receiving a good signal from the back down foot switch.

• The foot control base up L.E.D. illuminates to indicate that the PC control board is receiving a good signal from the base up foot switch.

• The foot control base down L.E.D. illuminates to indicate that the PC control board is receiving a good signal from the base down foot switch.

• The auto return back function L.E.D. is not used on this table.

• The auto return base function L.E.D. illuminates to indicate that the auto return circuit for the base function is activated. The L.E.D. stays illuminated until the base function has completed its portion of the auto return cycle.

• There are three Data Line L.E.D.'s; data line #1 L.E.D., data line #2 L.E.D., and data line #3 L.E.D.. Different combinations of these L.E.D's illuminate to indicate if the proper input signal is being sent to the PC control board from the membrane panels or hand control.

PARTS LIST

6.1 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

1.5 for parts ordering information. The parts list also illustrates disassembly and assembly

relationships of parts.

6.2 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.

for that component.

column lists the MIDMARK part number

SECTION VI PARTS LIST

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 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.

6.3 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.
