Bottom View Pre-Installation GENERAL All Gammex AccuChrom 3 Optical Alignment Systems provide an optical aid for rapid and accurate patient positioning and repositioning for therapy and simulator machines. TECHNICAL DESCRIPTION For the purpose of this manual, a single optical aligner will be referred to as a unit and a set of related aligners will be referred to as a system. Various combinations of the GLED-800 crosshair AccuChrom 3 and the GLED600 sagittal (straight line) AccuChrom 3 are used with different systems. The GLED-800 optical aligners, mounted on each side, project crosshairs along the X-axis. A GLED-800 optical aligner mounted on the ceiling projects a crosshair vertically along the Z-axis. The Sagittal GLED-600 optical aligner projects a straight line in the Z-Y plane. Z-Y X-Y X-Z Z-Y Plane Installation Requirements ELECTRICAL Each optical aligner is provided with a universal power supply (transformer) with an input of 100 to 240 volts AC at 50 to 60 Hz. The universal power supply plugs into a wall 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 aligner with a bayonet type locking power plug. TOOLS NEEDED In addition to some basic tools, such as screwdrivers, a hammer and a ladder; you will 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 alignment systems. A spinning laser may be used as an alternative to a water level. Contact us for more information. CAUTION: The location of each optical aligner is determined in relation to the therapy machine’s crosshair and isocenter. Before installing an optical alignment system, ask the physicist to verify that the field light aligns with the therapy machine’s isocenter. See Figure 1 on page 9. During commissioning/validation of a linear accelerator, please power off all AccuChrom 3 positioning units (to prevent damage caused by high levels of radiation). They may be powered back on immediately after commissioning/ validation. Gantry rotated 90 ° Overhead aligner (crosshair) Side aligner (crosshair) Side aligner (crosshair) Sagittal aligner Figure 1 Room Layout AccuChrom 3 Alignment Systems Pre-Installation Use a water level to line up the optical aligner’s exit reference point at the height of isocenter. See Figure 2 on page 10. PREPARING THE ROOM 1. Unpack each optical alignment unit and remove shipping stability screws according to 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 ACCURACY The collimator projected crosshair is used as a reference when determining the optical aligners locations. The light field should coincide with isocenter, the gantry should be level, 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 the center 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 if a difference in dot location is observed. USING THE LEVEL Use a level to determine the height of the optical aligner exit reference point when installing 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 alignment 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 exit reference point. 10 Horizontal line Showing the Height of the laser exit reference point. Front Pointer Figure 2 Use a water level to line up the alignment exit reference point at the height of isocenter. Figure 3 Rotate the gantry 90º and project a crosshair onto the wall. 11 Figure 4 Use a string to verify the location of the units. 12 Installing Optical Alignment Systems SIDE OPTICAL ALIGNER INSTALLATION For all GLED-800 installations. For angled walls, refer to page 17. 1. Rotate the gantry 90° to the 270° position and project a crosshair onto the wall. See Figure 3 on page 11. 2. Use a pencil and straight rule to trace the crosshair onto the wall. 3. Line up the template provided, so that the projected crosshair lines up with the optical aligner exit point on the template. Use a level to line up the template. 4. Mark the outer edge of the template and also mark the mounting holes. 5. Rotate the gantry 180° to the 90° position and repeat steps 2-4 on the opposite wall. 6. Return the gantry to 0°. 7. Tape a blank 8 X 10 piece of paper to the table. 8. Project the collimator crosshair onto the paper, keep the field as wide as possible. 9. Hold the ends of a string on each wall at the center of the crosshair traced in step 2. The string shadow should be in line with projected crosshair. See Figure 4 on page 12. 10. Drill the mounting holes. Tap threads or install anchors as necessary. 11. Remove the AccuChrom 3 from its packaging and remove shipping stability screws according to the pre-installation guide included with the unit. Remove two screws from the front cover using a 1/8” hex (allen) wrench. Slide the cover straight off towards the front. 13 Installing Optical Alignment Systems SIDE OPTICAL ALIGNER INSTALLATION (continued) 12. Use the two 1/4” hex bolts and washers to mount the optical aligner to the wall shown in Figure 5. The optical aligner must be firmly mounted. Oversized holes provide flexibility to line up the exit reference hole. Suitable anchors must be used. Wall anchors for masonry are provided in the mounting kit. Use a 3/8” diameter drill bit for the provided anchors. It may be helpful to shift the optics to ease installation of mounting bolts. Refer to the following pages for the methods of planar adjustments. Re-center the optics after mounting. 13. Do not replace the cover at this time. 14. Plug in the universal power supply. Attach the bayonet lock power plug to the bottom of the optical alignment system. Turn on the optical aligner. 15. Plug in the receiver. 16. Rotate the gantry 90° (so that the crosshair is projected onto the optical alignment system) and tape a piece of paper to the gantry head, covering the projected light field. 17. Adjust the optical aligner so that the projected aligner crosshair lines up with the collimator cross hair. Refer to the following pages for the methods for making optical alignment system adjustments. 18. Verify that the vertical line of the projected collimator crosshair passes through the screw holes in the top and the bottom cover of the optical aligner. See Figure 5 on page 15. 19. Verify that the horizontal line of the projected collimator crosshair falls on the horizontal alignment marks of the optical aligner. See Figure 5 on page 15. 20. Adjust for perpendicular lines if necessary. Refer to page 30. 21. Turn off the optical aligner. 22. Place the cover on and replace the screws. Take care not to bump the opticals. 23. Double check the alignment of the unit several times. 24. Return the gantry to 0°. 14 A Vertical Alignment Mark Horizontal Alignment Mark Horizontal Alignment Mark For Alignment Vertical line should pass thru holes ‘A’ and ‘B’. 1/4” Mounting Hex Bolt with washers Horizontal Line should fall on groove ‘C’ and edge ‘D’. Vertical Alignment Mark Figure 5 15 Second Side Optical Aligner Installation 1. Repeat the process used to mount the first optical aligner on the opposing wall. Using the crosshair of the first optical aligner to pencil a crosshair on this wall to determine the exit reference point and use the mounting template to identify the mounting holes. 2. Drill the mounting holes. 3. Unplug optical aligner and remove the cover. 4. Mount the unit to the wall using the 1/4 hex bolts and washers. 5. Plug in and turn on optical aligner. 6. Hold piece of paper in the path between the two aligners by looking at paper, verify: • optical alignment system lines overlap • front pointer (isocenter) lines up with the optical alignment system lines • vertical lines are plumb. • horizontal lines are level. • lines are sharp and focused at isocenter. NOTE: If there is no front pointer, raise the table to isocenter and align the first optical aligner with the table edge. Align the second unit with the first. Sheet of paper Verify that the side aligner crosshairs line. They should overlap each other. Figure 6 Use a blank sheet of paper to verify the placement of the side optical aligners. 16 Installation on Angled Walls 1. When mounting on angled walls, cut out and fold the angular template to the flat wall template. 2. Use a water level to determine the height of the optical aligner exit reference point. (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 the projected crosshair. Several people may be needed. See previously mentioned Figure 4. 6. On each wall use the template with its extension. Follow the directions provided with the angular template. Level the template and mark the mounting holes. 7. Drill the mounting holes. Tap threads or install anchors as necessary. Attach the angular bracket to the unit using four bolts and nuts. Leave the nuts finger tight until all course adjustments have been made. See Figure 7 below. 8. Mount the optical aligner using the angular bracket to point the unit towards isocenter. 9. Repeat the process for any remaining units on angled walls. Figure 7 17 Ceiling Optical Aligner Installation 1. 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 a pencil. 4. Move collimator out of the way. 5. Hold a plumb bob from the ceiling so that the bottom weight hits the dot on the table. The point at which the string touches the ceiling indicates the optical aligner 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 to cover 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 to the wall as shown in Figure 5. The unit must be firmly mounted. Oversized holes in the aligner back mounting plate provide flexibility to line up the exit reference hole. Suitable anchors must be used. Wall anchors for masonry are provided in the mounting kit. Use a 3/8” diameter drill bit for the provided anchors. It may be helpful to shift the optics to ease installation of mounting bolts. See page 30 for planar adjustments. 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 the dot on the table. 12. Raise and lower the table. The crosshair should stay aligned for the entire movement of the table. Refer to Optical Alignment Adjustments on page 31 to make corrections. NOTE: If the aligner is mounted in a recess, cut a hole in the ceiling tile large enough to allow the entire crosshair to be projected. 18 X Figure 8 Figure 9 Use a string and the ceiling optical aligner crosshair to determine the placement of the sagittal laser. 19 Sagittal Optical Aligner Installation The Sagittal Optical Aligner is 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 a plumb bob string to the center of the table so that the string line aligns with the crosshair. Point A in Figure 9. If your system does not contain a ceiling unit, use the collimator-projected crosshair. 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 projected sagittal 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 vertical optical 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 system to the wall as shown in Figure 5. The unit must be firmly mounted. Oversized holes in the aligner back mounting plate provide flexibility to line up the exit reference hole. Suitable anchors must be used. Wall anchors for masonry are provided in the mounting kit. Use a 3/8” diameter drill bit for the provided anchors. It may be helpful to shift the optics to ease installation of mounting bolts. See later pages for planar adjustments. 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 the table. 20 Remote Control Remote control is a radio communication feature that allows the operator to change color and boost brightness with a hand-held remote transmitter. Each optical alignment system has a separate receiver that responds to the operator's remote control. The remote control and optical alignment system both have an ID switch. The ID switch sets the identification number for the system. This allows different rooms to operate remote control optical alignment systems in close proximity without interference. All remote control receivers in a room will have the same ID number. Different rooms will have different remote ID numbers. To communicate properly, the remote control ID must be set to match the optical alignment 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. Lock/Unlock and On/Off Unit and Code settings: (quick start) A single remote control transmitter may be used to operate one or more AccuChrom 3 positioners. Dual Inline Package (DIP) switches are used to prevent unwanted interference between adjacent systems. Use the UNIT switches to determine which AccuChrom 3 positioners will respond to which yellow UNIT button on the remote. It is possible to have some units respond after pressing button 1 and others after button 2 (and so on). Keep the CODE switches on all AccuChrom 3 aligners and the remote control that will be used to command them at the factory default (0) setting unless you experience interference. 21 UNIT switches CODE switches Bottom of Unit The following illustration shows the settings which result in successful and unsuccessful communication. Use the available switch combinations to configure systems as desired. For more details about Unit and Code settings, continue to the next pages. 22 Typical system configurations Typical configuration: three optical aligner units controlled by one remote control transmitter; Unit = 1 Code =0 23 Typical configuration: four optical aligner units controlled by one remote control transmitter; Unit = 2 Code = 0 24 Unit and Code settings Your new optical aligner has been factory set to a default configuration enabling testing during manufacture. The installer and/or end user shall set the parameters based on the desired customer configuration at the installation site. Unit By use of the Unit switch, a system is configured to either include (within the system) or exclude (from the system) optical aligner(s) to be commanded by that remote 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 remote control transmitter must match the 5-position UNIT DIP switch setting of optical aligner(s) to be commanded by that remote control transmitter. The *factory-set default value is Unit 1. AccuChrom 3 positioner Unit values may be configured according to this table.

UNIT DIP switch How to select Remote Control Transmitter Unit setting The Unit setting is user-selected by pressing the correct push-button along top row of the remote control transmitter as illustrated below after the remote control is on (green LED above Lock/Unlock button illuminated). Once the user selects a Unit number (with green Lock/Unlock LED illuminated), this Unit number is retained until a different Unit button is pressed. 26 Code The factory default Code value should work in most applications; the installer/user should not need to change the Code setting. Only if interference from other 433.92 MHz remote control devices is present, would this Code value be changed. Wireless encryption (tunnel) is used between remote control transmitter and optical aligners to prevent/mitigate interference from other devices sharing the 433.92 MHz frequency. The optical aligner is capable of operation using any of eight distinct encryption (coding) scheme combinations selected by the threeposition CODE DIP switches. In order for any remote control transmitter to work with any optical aligner(s), the ON/OFF position on the three internal DIP switches the remote control transmitter 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.

The default setting (Code 0) should work. However if you must change it, follow these instructions to change the CODE DIP switches inside the remote control transmitter. Step 1) Set remote control unit on table face-down with back facing up. Step 2) Remove the battery compartment cover. Step 3) Remove four screws on the back of the case (two within battery compartment). Step 4) Remove case back; set the Code DIP switches to desired setting. OFF ON Note: The switch is off (0) when pushed up or away from batteries toward the word “CODE” on circuit board. Step 5) Reassemble remote control transmitter reversing the above steps. 29 Adjustments Shift Skew Shift:: Planar Shift 30 Alignment and Adjustments and Positioning– AccuChrom 3 Warning - Risk of incorrect (diagnosis or treatment) if alignment is not done correctly. • Isocenter of alignment optical alignment systems must coincide with isocenter of diagnostic of treatment equipment. Test alignment of optical aligner daily, before use, for first month of operation and weekly after first month. Newly installed equipment will shift as building walls and floor settle and as building materials dry out. Re-align optical alignment system to isocenter before use, if anything has shifted. • The optical alignment system must be aligned with the diagnostic or therapy equipment to be safely useful. Only a GAMMEX service technician, or trained Medical Physicist, Biotech Engineer or Service Technician should perform the alignment. Caution - Optical Radiation Risk of eye damage. Do not stare directly at the light source. • Alignment procedures need to be performed with the optical alignment system powered 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 alignment system set-up. Removing the Cover On the AccuChrom 3, most adjustments and repairs require the removal of the front cover. Remove the cover as follows: First, turn off the unit. Unplug the power cord from the main socket. Remove two screws from the front cover using an 1/8” allen wrench. 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 the optical aligner. Unplug the power cord. Replace the front cover and secure it with the two screws. Take care not to jar the optical aligner. Plug in the power cord. 31 Alignment and Adjustments – AccuChrom 3 GENERAL Test the alignment of the optical alignment systems daily, before use, for the first month after installation. In a new installation some building movements can be expected. The first month test the system at least weekly. Isocenter of the alignment optical alignment system must coincide with the isocenter of the diagnostic or treatment equipment. CEILING AND SAGITTAL OPTICAL ALIGNERS Tape a piece of typing paper to the table under the gantry. That has been leveled and set at 0°. Project a crosshair on the paper from the gantry. Mark the center point. Move the gantry out of the way. Project the Ceiling optical aligner crosshair on the paper. Raise and lower the table. The center of the crosshair should align with the dot on the paper at all times. The Sagittal line should pass through the dot on the paper at all times. SIDE OPTICAL ALIGNERS Turn on both side optical aligners. Use a piece of typing paper held perpendicular to the optical aligner light. The two projected optical aligner crosshairs should overlap on the paper. See Figure 6 on page 16. With the gantry at 0° use a front pointer, which is shown in Figure 2, to verify that both side optical aligners hit isocenter. If there is not a front pointer, raise the table to isocenter and project a crosshair on the table to verify that the side optical aligners hit isocenter. Maintenance/Cleaning Once 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 cover is delicate. Use only a camera lens brush or other soft brushes for this purpose. 32 Troubleshooting PROBLEM NO OPTICAL ALIGNMENT LIGHT POSSIBLE CAUSE Wall switch not on. POSSIBLE REMEDY Check switch by turning optical aligner off and on. Wall switch not in full on position. Verify switch lever is in the full on position Plug/connector not plugged Verify plug is in the fully in. Plug partially plugged in. plugged in position. Power supply not functioning. INTERMITTENT OPTICAL ALIGNMENT LIGHT Use a voltmeter to measure the voltage output of power supply wall plug. If voltage is less than 18 or greater than 23 VDC, the power supply will need to be replaced. Call Gammex Sales and Service for assistance. Use a voltmeter to measure the voltage output of power supply wall plug. If voltage is less than 18 or greater than 23 VDC, the power supply will need to be replaced. Call Gammex Sales and Service for assistance. Gammex uses optical alignment systems that are matched for chromacity. The company strives to match unit-to-unit consistency as closely as possible. Over time, chromacity may change slightly so that optical aligners purchased at different times may display slight color variations. If you have questions on this, please contact the Gammex Service Department. 33 PROBLEM MAIN UNIT DOES NOT RESPOND TO COMMANDS FROM REMOTE CONTROL TRANSMITTER POSSIBLE CAUSE Remote Control Transmitter is off. POSSIBLE REMEDY Turn on (unlock) the remote control transmitter by pressing lock/unlock switch until “on LED” is illuminated. Dead batteries in remote Replace batteries (page control transmitter. 36 of this manual) and (parts list table page 37) The “Unit” setting is mis-matched. Verify/set positioner unit value setting (page 25 of this manual) and then power on positioner unit and remote control. Select same “unit” on the remote control transmitter (page 26 How to Select Remote Control Transmitter unit setting) as is set on main unit DIP switches. Mis-matched “Code” setting. Verify/set positioner Code Value Setting (page 2728 How to Set Optical Aligner Code Setting) and then verify remote control value (page 29 How to Change Remote Control Transmitter Code Setting) to match the positioner code value. Power on positioner and remote control transmitter 34 AccuChrom 3 LED Replacement Kit Instructions The following directions outline the procedure for replacing the heat sink module. Read and familiarize yourself with all of the steps before beginning. Tools Required: 3/32,7/64, and 1/8” allen wrenches 1. 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 support frame of the unit. 4. Two small dowel pins help align the heatsink in the proper location on the support frame. The tight tolerances on these parts makes for a tight fit. The center hole in the heatsink has been provided to help with removal. Thread one of the long screws back into the center hole and it will help separate the heatsink from the support frame. There will 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 as the ribbon cable will allow. Unplug the ribbon cable from the underside of the driver board and fully remove the heatsink. Remove the long screw from the center hole and set 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 lose this screw. 7. Unplug the thermostat from the front edge of the driver board. 8.Gently separate the driver board from the heatsink. Carefully grasp it by the edges and lift it upwards. 9. Transfer the driver board to the new heatsink module provided with the replacement kit. Connect the new thermostat and replace the #4 screw. 10. Bring the new heat sink assembly close enough to reconnect the ribbon cable. Make sure the ribbon cable’s connector fits over all of the pins on the driver board and is fully engaged. 11. Align the heat sink to the support frame and secure it with the two long screws. Alternate between tightening both screws to bring the components together evenly. 12. Check the alignment of the unit. Small corrections may need to be made because the internal components have been handled. Note: Electronic components are sensitive to static electricity. Use standard ESD precautions when performing the replacement procedure. 35 REPLACING THE TRANSMITTER BATTERIES The transmitter has a battery compartment on the back that can be opened by pushing down on the catch and sliding it toward the end of the case. The cover may be tight. It may be necessary to very carefully pry the opening apart at the parting line. It is very important to replace the batteries with the proper polarity in the right direction as shown. The spring contact always matches the negative (-) end. These batteries are not rechargeable. Do not recharge them. They are long life lithium AA, 3.6V, 2.4Ah batteries. Transmitter batteries will not often require replacement, but when they do, they are available from Gammex Sales Department. The transmitter will not function using commonly available AA batteries, they are not the correct voltage. DISMANTLING The AccuChrom 3 can be removed from the wall by following the reverse of the installation instructions.
