1.3 Description Of 355 Lighting System

A. General Description (See Figure 1-1).

The 355 Lighting System is a general purpose lighting system designed specifically for performing general medical examinations and procedures. Listed are the two different models available:

355 (-001 thru -004 &

-007 thru -010)..........................120 VAC Models

355 (-012 thru -015).......................... 220 VAC Models

The major serviceable components of the lighting system are the transformer, fuse / fuse holder, bulb socket, ON / STANDBY switch, main pivot stop, counterbalance assembly, ball pivot joint assembly which includes ball pivot stop, lamp tube pivot stop, lighthead pivot bearing stop, lamp tube brake assembly, lighthead brake assembly, and top cap assembly.

B. Model 355 (-001 thru -004 & -007 thru -010) The-

ory of Operation (See Figure 5-1 for wiring diagram / electrical schematic)

Line voltage is supplied thru the line fuse (F1) to the transformer. If to o m uch c ur rent is dr a wn by the lighting system's circuitry, the line fuse (F1) blows. The transformer will provide 12.27 +/- 0.37 VAC output to power the light circuit based on an ideal 120.0 VAC input. Because there are facilities which cannot supply the ideal level of input voltage, the transformer is designed with three different primary input taps which can be used, based on the voltage level av ailable at a particular facility. If the facility's voltage is 117.0 VA C or lower, the

114.0 VA C (yellow) transformer input tap must be used. If the facility's voltage is between 117.1 to 123.0 VAC, the 120.0 VAC (orange) transformer input tap must be used. If the facility's voltage is 123.1 VAC or higher, the

126.0 VAC (red) transformer input tap must be used. Using the correct transf ormer input tap will result in a transformer output of 12.27 +/- 0.37 VAC.

When the ON / STANDBY switch is switched to ON, the output voltage from the transformer secondary tap is applied across the bulb assembly causing the bulb to illuminate. Turning the ON / STANDBY switch to STANDBY opens the circuit, causing the bulb to stop illuminating. However, power is still applied to the primary side of the transformer.

Line voltage is supplied thru the line fuse (F1) to the transformer. If to o m uch c ur rent is dr a wn by the lighting system's circuitry, the line fuse (F1) blows. The trans-

former will provide 12.27 +/- 0.37 VAC output to power the light circuit based on an ideal 220.0 VA C input. Because there are facilities which cannot supply the ideal level of input voltage, the transformer has three primary input taps which can be used, based on the voltage level available at a particular facility. If the facility’s voltage is 225 VAC or lower, the 220 VAC (yellow) transformer input tap must be used. If the facility’s voltage is between 225.1 and 235.0 VAC, the 230 VAC (orange) transformer input tap must be used. If the facility’s v oltage is 235.1 VAC or higher, the 240 VAC (red) transformer input tap must be used. Using the correct transformer input tap will result in a transformer output of 12.27 +/- 0.37 VAC.

PARTS LIST

SECTION VI 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.

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. 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 hav e 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.
