7Pre-InstallationGENERALAll Gammex AccuChrom 3 Optical Alignment Systems provide an optical aid forrapid and accurate patient positioning and repositioning for therapy and simulatormachines.TECHNICAL DESCRIPTIONFor the purpose of this manual, a single optical aligner will be referred to as aunit and a set of related aligners will be referred to as a system.Various combinations of the GLED-800 crosshair AccuChrom 3 and the GLED-600 sagittal (straight line) AccuChrom 3 are used with different systems. TheGLED-800 optical aligners, mounted on each side, project crosshairs along theX-axis. A GLED-800 optical aligner mounted on the ceiling projects a crosshairvertically along the Z-axis. The Sagittal GLED-600 optical aligner projects astraight line in the Z-Y plane.XXXYZ-YPlaneX-ZX-YZ-Y
8Installation RequirementsELECTRICALEach optical aligner is provided with a universal power supply (transformer) with aninput of 100 to 240 volts AC at 50 to 60 Hz. The universal power supply plugs into awall outlet using one of four (4) interchangeable “snap-in” plugs that fit most outlets.A 1.83 meter (6 foot) power cord supplies 18 Volt DC power to the optical alignerwith a bayonet type locking power plug.TOOLS NEEDEDIn addition to some basic tools, such as screwdrivers, a hammer and a ladder; youwill need an electric hammer drill, plumb bob, water level, masking tape and 15M(50 feet) of string. The mounting hardware, a 1/4-20 tap, 2 drill bits (#7 and 3/8”),1/4” anchor and a 3/16” hex (allen) wrench, are included with the optical alignmentsystems. A spinning laser may be used as an alternative to a water level. Contactus for more information.CAUTION: The location of each optical aligner is determined in relation to thetherapy machine’s crosshair and isocenter. Before installing an optical alignmentsystem, ask the physicist to verify that the field light aligns with the therapymachine’s isocenter. See Figure 1 on page 9.During commissioning/validation of a linear accelerator, please power off allAccuChrom 3 positioning units (to prevent damage caused by high levels ofradiation). They may be powered back on immediately after commissioning/validation.

10Pre-InstallationUse a water level to line up the optical aligner’s exit reference point at the height ofisocenter. See Figure 2 on page 10.PREPARING THE ROOM1. Unpack each optical alignment unit and remove shipping stability screws accordingto the pre-installation guide included with the unit. 2. Turn the linear accelerator lamp on.3. Set gantry and collimator to 0º and level the collimator.4. Lower the table as far as possible.COLLIMATOR CROSSHAIR ACCURACYThe collimator projected crosshair is used as a reference when determining the opticalaligners locations. The light field should coincide with isocenter, the gantry should belevel, and if collimator crosshair displacement exists, it should be compensated for.1. Project a collimator crosshair onto a piece of paper taped to the table and mark thecenter with a dot.2. Rotate through 360° and mark the center again.3. If there is a difference between the two dots, review this finding with site physicist.The physicist will make the final determination as to where to place the crosshair ifa difference in dot location is observed.USING THE LEVELUse a level to determine the height of the optical aligner exit reference point wheninstalling optical alignment systems in a simulator room or in a room with angled walls.In standard treatment rooms, the level should also be used to verify the optical align-ment system location. See Figure 2 on page 10.1. Raise the table to the front pointer (isocenter).2. Remove caps on ends of level and remove air bubbles.3. Line up with the table edge and with the wall. 4. The line on the wall indicates the horizontal axis of the optical aligner exitreference point.

NOTE:If there is no front pointer, raise the table to isocenter and align the firstoptical aligner with the table edge. Align the second unit with the first. Figure 6Use a blank sheet of paper to verify the placement of the side optical aligners.Sheet of paperVerify that the sidealigner crosshairsline. They shouldoverlap each other.
17Installation on Angled Walls1. When mounting on angled walls, cut out and fold the angular template to the flatwall template.2. Use a water level to determine the height of the optical aligner exit referencepoint. (refer to pages 10 &11)3. Set gantry at 0°, tape a piece of paper to the table.4. Project a crosshair onto the paper, keeping the field as wide as possible.5. Hold the ends of a string on each wall until the string shadow is in line with theprojected crosshair. Several people may be needed. See previously mentionedFigure 4.6. On each wall use the template with its extension. Follow the directions providedwith the angular template. Level the template and mark the mounting holes.7. Drill the mounting holes. Tap threads or install anchors as necessary. Attachthe angular bracket to the unit using four bolts and nuts. Leave the nuts fingertight until all course adjustments have been made. See Figure 7 below.8. Mount the optical aligner using the angular bracket to point the unit towardsisocenter. 9. Repeat the process for any remaining units on angled walls.Figure 7
18Ceiling Optical Aligner Installation1. Level gantry at 0° and place the table at isocenter height.2. Tape a piece of paper to the table.3. Project a crosshair and mark the crosshair center point on the paper with apencil.4. Move collimator out of the way.5. Hold a plumb bob from the ceiling so that the bottom weight hits the dot on thetable. The point at which the string touches the ceiling indicates the opticalaligner exit reference point. Mark this location with a pencil. See Figure 8.6. Use the template to mark the location of the mounting holes.7. Drill the mounting holes. Tap or install anchors as necessary. It is helpful tocover the table to catch drill filmings. 8. Unplug the optical aligner and remove the cover.9. Use the two 1/4” hex mounting bolts and washers to mount the optical aligner tothe wall as shown in Figure 5. The unit must be firmly mounted. Oversizedholes in the aligner back mounting plate provide flexibility to line up the exit ref-erence hole. Suitable anchors must be used. Wall anchors for masonry areprovided in the mounting kit. Use a 3/8” diameter drill bit for the provided anchors. It may be helpful to shiftthe optics to ease installation of mounting bolts. See page 30 for planar adjust-ments. Re-center the optics after mounting. 10. Plug in and turn on optical alignment system.11. The center of the optical alignment system crosshair should correspond with thedot on the table.12. Raise and lower the table. The crosshair should stay aligned for the entiremovement of the table. Refer to Optical Alignment Adjustments on page 31 tomake corrections.NOTE:If the aligner is mounted in a recess, cut a hole in the ceiling tile largeenough to allow the entire crosshair to be projected.

20Sagittal Optical Aligner InstallationThe Sagittal Optical Aligneris mounted high on the wall. See Figure 9 room layout.The minimum install height is 7', or higher.1. Set the table to isocenter height.2. Use the crosshair from the ceiling optical aligner as a reference and tape aplumb bob string to the center of the table so that the string line aligns with thecrosshair. Point A in Figure 9. If your system does not contain a ceiling unit, use the collimator-projectedcrosshair. Be sure to check for collimator accuracy. Refer to page 10. 3. Move the table up and down to verify tracking of the string line. The projectedsagittal line should cover or, overlay the line formed by the string.4. The point at which the string hits the wall indicates the center of the verticaloptical aligner exit reference point. Point B in Figure 9.5. Use the template to determine the location of the mounting holes.6. Drill the mounting holes. Tap or install anchors as necessary.7. Unplug the optical aligner and remove the cover.8. Use the two 1/4” allen bolts and washers to mount the optical alignment systemto the wall as shown in Figure 5. The unit must be firmly mounted. Oversizedholes in the aligner back mounting plate provide flexibility to line up the exitreference hole. Suitable anchors must be used. Wall anchors for masonry areprovided in the mounting kit. Use a 3/8” diameter drill bit for the provided anchors. It may be helpful to shiftthe optics to ease installation of mounting bolts. See later pages for planaradjustments. Re-center the optics after mounting. 9. Plug in and turn on optical aligner.10. Verify that the optical alignment line tracks the crosshair projected onto thetable.
21Remote ControlRemote control is a radio communication feature that allows the operator tochange color and boost brightness with a hand-held remote transmitter. Eachoptical alignment system has a separate receiver that responds to the operator'sremote control. The remote control and optical alignment system both have anID switch. The ID switch sets the identification number for the system. This al-lows different rooms to operate remote control optical alignment systems in closeproximity without interference. All remote control receivers in a room will havethe same ID number. Different rooms will have different remote ID numbers. Tocommunicate properly, the remote control ID must be set to match the opticalalignment system IDs of all of the optical alignment system receivers in a system.To turn remote on press the lock/unlock button. Green light will illuminate. Unit and Code settings: (quick start)A single remote control transmitter may be used to operate one or moreAccuChrom 3 positioners. Dual Inline Package (DIP) switches are used toprevent unwanted interference between adjacent systems.Use the UNIT switches to determine which AccuChrom 3 positioners will respondto which yellow UNIT button on the remote. It is possible to have some unitsrespond after pressing button 1 and others after button 2 (and so on).Keep the CODE switches on all AccuChrom 3 aligners and the remote controlthat will be used to command them at the factory default (0) setting unless youexperience interference.

22The following illustration shows the settings which result in successful andunsuccessful communication. Use the available switch combinations toconfigure systems as desired. For more details about Unit and Code settings,continue to the next pages. CODE switches UNIT switchesBottom of Unit
23Typical system configurationsTypical configuration: three optical aligner units controlled by one remotecontrol transmitter; Unit = 1 Code =0
24Typical configuration: four optical aligner units controlled by one remote controltransmitter; Unit = 2 Code = 0
25Unit and Code settingsYour new optical aligner has been factory set to a default configuration enablingtesting during manufacture. The installer and/or end user shall set the parameters based on the desiredcustomer configuration at the installation site. UnitBy use of the Unit switch, a system is configured to either include (within thesystem) or exclude (from the system) optical aligner(s) to be commanded by thatremote control transmitter. A “one-to-one” or a “one-to-many” command and control structure (association)can be configured through use of the Unit switch. The Unit selection of a remotecontrol transmitter must match the 5-position UNIT DIP switch setting of opticalaligner(s) to be commanded by that remote control transmitter. The *factory-set default value is Unit 1. AccuChrom 3 positioner Unit valuesmay be configured according to this table.AccuChrom 3positioner 5-position unitDIP switchswitch 1 switch 2 switch 3 switch 4 switch 5Unit 1* On (1) Off (0) Off (0) Off (0) Off (0)Unit 2 Off (0) On (1) Off (0) Off (0) Off (0)Unit 3 Off (0) Off (0) On (1) Off (0) Off (0)Unit 4 Off (0) Off (0) Off (0) On (1) Off (0)Unit 5 Off (0) Off (0) Off (0) Off (0) On (1)
26How to select optical aligner Unit settingThe Unit is configured through the 5-position DIP switch located on the bottom ofthe optical aligner as illustrated below. How to select Remote Control Transmitter Unit settingThe Unit setting is user-selected by pressing the correct push-button along toprow of the remote control transmitter as illustrated below after the remote controlis on (green LED above Lock/Unlock button illuminated). Once the user selects aUnit number (with green Lock/Unlock LED illuminated), this Unit number isretained until a different Unit button is pressed.UNIT DIPswitch
27CodeThe factory default Code value should work in most applications; theinstaller/user should not need to change the Code setting. Only if interferencefrom other 433.92 MHz remote control devices is present, would this Code valuebe changed.Wireless encryption (tunnel) is used between remote control transmitter andoptical aligners to prevent/mitigate interference from other devices sharing the433.92 MHz frequency. The optical aligner is capable of operation using any ofeight distinct encryption (coding) scheme combinations selected by the three-position CODE DIP switches. In order for any remote control transmitter to work with any optical aligner(s), theON/OFF position on the three internal DIP switches the remote control transmit-ter and the externally accessible optical aligner (3-position Code DIP switch)must precisely match. Note the *default factory-set value is encryption code 0. However, other values may be used to mitigate interference.

31Alignment and Adjustments and Positioning– AccuChrom 3 Warning - Risk of incorrect (diagnosis or treatment) if alignment is not donecorrectly. • Isocenter of alignment optical alignment systems must coincide with isocenterof diagnostic of treatment equipment. Test alignment of optical aligner daily,before use, for first month of operation and weekly after first month. Newlyinstalled equipment will shift as building walls and floor settle and as buildingmaterials dry out. Re-align optical alignment system to isocenter before use, ifanything has shifted.• The optical alignment system must be aligned with the diagnostic or therapyequipment to be safely useful. Only a GAMMEX service technician, or trainedMedical Physicist, Biotech Engineer or Service Technician should perform thealignment.Caution - Optical Radiation Risk of eye damage. Do not stare directly at thelight source. • Alignment procedures need to be performed with the optical alignment systempowered on.• Look only at optical alignment system light reflected from a diffuse surface(like paper or a wall).See Typical Room Layout (page 9) for general concept of optical alignmentsystem set-up.Removing the CoverOn the AccuChrom 3, most adjustments and repairs require the removal of the frontcover. Remove the cover as follows: First, turn off the unit. Unplug the power cordfrom the main socket. Remove two screws from the front cover using an 1/8” allenwrench. Slide the cover off.Plug in the power cord and turn on the unit to make adjustments. To replace the cover after making adjustments, reverse the process. Turn off theoptical aligner. Unplug the power cord. Replace the front cover and secure it with thetwo screws.Take care not to jar the optical aligner. Plug in the power cord.
32Alignment and Adjustments – AccuChrom 3 GENERALTest the alignment of the optical alignment systems daily, before use, for the firstmonth after installation. In a new installation some building movements can beexpected. The first month test the system at least weekly. Isocenter of thealignment optical alignment system must coincide with the isocenter of thediagnostic or treatment equipment.CEILING AND SAGITTAL OPTICAL ALIGNERSTape a piece of typing paper to the table under the gantry. That has been leveledand set at 0°. Project a crosshair on the paper from the gantry. Mark the centerpoint. Move the gantry out of the way. Project the Ceiling optical aligner crosshairon the paper. Raise and lower the table. The center of the crosshair should alignwith the dot on the paper at all times. The Sagittal line should pass through the doton the paper at all times. SIDE OPTICAL ALIGNERSTurn on both side optical aligners. Use a piece of typing paper held perpendicularto the optical aligner light. The two projected optical aligner crosshairs should over-lap on the paper. See Figure 6 on page 16.With the gantry at 0° use a front pointer, which is shown inFigure 2, to verify thatboth side optical aligners hit isocenter. If there is not a front pointer, raise the tableto isocenter and project a crosshair on the table to verify that the side optical align-ers hit isocenter.Maintenance/CleaningOnce installed, the Gammex Aligners should require no maintenance other than the cleaning of mirrors and lenses according to standard optical practices.Occasional outside wiping of the dust cover may be necessary. The dust coveris delicate. Use only a camera lens brush or other soft brushes for this purpose.
33TroubleshootingGammex uses optical alignment systems that are matched for chromacity. Thecompany strives to match unit-to-unit consistency as closely as possible. Overtime, chromacity may change slightly so that optical aligners purchased atdifferent times may display slight color variations. If you have questions on this,please contact the Gammex Service Department. PROBLEM POSSIBLE CAUSE POSSIBLE REMEDYNO OPTICAL ALIGNMENTLIGHTWall switch not on.

35AccuChrom 3 LED Replacement Kit InstructionsThe following directions outline the procedure for replacing the heat sink module. Readand familiarize yourself with all of the steps before beginning.Tools Required: 3/32,7/64, and 1/8” allen wrenches1. Turn off and unplug the unit from the power source.2. Remove the two screws holding the front cover on using the 1/8” allen wrench.Slide the cover off and set it aside.3. Loosen and remove the two 3” long screws fastening the heatsink module to the sup-port frame of the unit.4. Two small dowel pins help align the heatsink in the proper location on the supportframe. The tight tolerances on these parts makes for a tight fit. The center hole in theheatsink has been provided to help with removal. Thread one of the long screws backinto the center hole and it will help separate the heatsink from the support frame. Therewill be some resistance due to friction of the dowel pins. 5. Once the heatsink has been separated from the support frame withdraw it as far asthe ribbon cable will allow. Unplug the ribbon cable from the underside of the driverboard and fully remove the heatsink. Remove the long screw from the center hole andset it with the other one. Do not lose either of these screws.6. Remove the single #4 screw fastening the driver board to the heatsink. Do not losethis screw.7. Unplug the thermostat from thefront edge of the driver board.8.Gently separate the driver boardfrom the heatsink. Carefully grasp itby the edges and lift it upwards.9. Transfer the driver board to thenew heatsink module provided withthe replacement kit. Connect thenew thermostat and replace the #4screw.10. Bring the new heat sink assem-bly close enough to reconnect theribbon cable. Make sure the ribboncable’s connector fits over all of thepins on the driver board and is fullyengaged.11. Align the heat sink to the supportframe and secure it with the two longscrews. Alternate between tighten-ing both screws to bring thecomponents together evenly. 12. Check the alignment of the unit.Small corrections may need to bemade because the internal compo-nents have been handled. Note: Electronic components are sensitive to static electricity. Use standard ESD precautions when performing the replacement procedure.
36REPLACING THE TRANSMITTER BATTERIESThe transmitter has a battery compartment on the back that can be opened bypushing down on the catch and sliding it toward the end of the case. The covermay be tight. It may be necessary to very carefully pry the opening apart at theparting line.It is very important to replace the batteries with the proper polarity in the rightdirection as shown. The spring contact always matches the negative (-) end.These batteries are not rechargeable. Do not recharge them. They are long lifelithium AA, 3.6V, 2.4Ah batteries. Transmitter batteries will not often requirereplacement, but when they do, they are available from Gammex Sales Depart-ment. The transmitter will not function using commonly available AA batteries,they are not the correct voltage.
