All Rights Reserved. 3 Installation Manual | Power Conditioner for Accuray CyberKnife® GENERAL DESCRIPTION The Series 700A/V-S Power Conditioner is designed to supply reliable, clean regulated power to critical loads. An efficient design with state of the art micro-processor controlled solid state devices provide immunity to all line disturbances. The basic design consists of a three phase triple shielded isolation transformer with seven separate voltage taps per phase. Output regulation is achieved by monitoring the input and automatically switching taps anytime the input line sags or surges. The use of a triple shielded isolation transformer provides superior common mode and transverse mode noise attenuation. Automatic switching occurs during current zero allowing noise free switches for both leading and lagging power factor loads that are connected to the Series 700A/V-S. MONITOR Monitoring of the Series 700A/V-S is simple, clean and effective. Three green light indicators are utilized to display “POWER ON” (output line to neutral for each phase) and one red light indicator to display “ALERT”. The “POWER ON” display is connected directly to the output that indicates the Series 700A/V-S is operating properly with just a quick glance. The “ALERT” display represents an over-temp problem or output voltage loss (optional) when illuminated, and will shut down the output, but cooling fans remain on. Overtemp thermal sensors are strategically located at critical points on the regulator assemblies and transformer. The main AC input circuit breaker must be turned off in order to reset the “ALERT” light. PROTECTION Protection is accomplished very effectively to minimize failures and the cost of repairs. A total of five major devices protect the Series 700A/V-S. 1. The input is protected with a integrally mounted AC circuit breaker for abnormal current overloads and provides a convenient means of disconnecting utility power. As an option the input breaker may be equipped with a shunt trip device that is interfaced with a REMOTE EMERGENCY POWER OFF PUSH BUTTON. By pressing this button, the input breaker will trip and disable the Series 700A/V-S completely. The input breaker must be physically reset before unit will turn on again. 2. The main transformer is protected by fuse links connecting the SCR regulators together, and are designed to clear in the event that two or more SCR’s should fail. This will prevent a transformer tap short and the possibility of transformer failure. 3. (Optional) The output of the Series 700A/V-S is constantly monitored for extreme over and under voltage conditions. This device monitors each output phase and will electronically disable the Series 700A/V-S when any phase exceeds +10% or -10% of nominal output voltage. 4. Overtemp sensing devices are mounted at critical points on the SCR regulating assembly and the main transformer. When an overtemp condition exists the “ALERT” light will illuminate and hold until the overtemp is corrected. There are no automatic shut-off circuits for the “ALERT” condition. The main AC input breaker must be turned off in order to reset the “ALERT” light. 5. Each output of the Series 700A/V-S is protected with an integrally mounted AC breaker for abnormal current overloads and provides a convenient means of disconnecting power from the load. 4 GENERAL DESCRIPTION CONTINUED OPERATION The Series 700A/V-S Power Conditioner is operated by simply turning on the main AC input circuit breaker. Each unit is provided with a bypass switch. This is a no load switch and MUST only be operated when the unit is OFF. The bypass switch should be in the “NORMAL” position unless a problem occurs with the system. If a problem occurs, turn OFF the main AC circuit breaker and turn the bypass switch to the “BYPASS” position. Re-energize the system by turning on the AC circuit breaker and contact the Customer Support Department for repairs. Any ‘ALERT” condition requires the main AC input breaker to be turned off in order to reset the “ALERT” light. THEORY OF OPERATION The Series 700A/V-S Power Line Conditioner provides the triple function of isolation, noise attenuation and voltage regulation. The first two functions are provided by the power transformer, whereas the third function of voltage regulation is achieved through solid state thyristors (SCR’s) connected to taps on the power transformer. A microprocessor monitors and controls the overall function of regulating the system. The power transformer is manufactured with a unique method of shielding which produces very low capacitive coupling between the primary and secondary. This low coupling provides excellent attenuation of the common-mode noise. In addition, special care is taken in the design of the transformer to attenuate transverse-mode noise above 1000 Hz. The power transformer has taps to which solid state switches (SCR’s) are connected. The voltage regulator incorporated in the Series 700A/V-S Power Line Conditioner is microprocessor controlled to achieve optimum correction time of input voltage sags and surges. The response time is typically one (1/2) cycle for 100% correction, therefore, a very smooth switch takes place undetected by computer equipment. As the input voltage (building power) varies, the voltage available at each tap of the transformer will also change. The amount of variation is dependent upon the input sag or surge, turns ratio and transformer losses. By selecting a particular tap voltage, the output can be kept within a tight range. The way in which this is accomplished is that an electronic control card using a micro-processor continually monitors the input voltage. When a voltage fluctuation occurs, which exceeds the limit of rated regulation (typically . 2%), the output is switched to another tap, that is within the required range. This “switch” will be made at the next current zero crossing to allow for both leading and lagging power loads to be connected to the conditioner.

The manual bypass switch is used to bypass all power electronics in case of failure. NORMAL MODE With the switch in the normal position, the Series 700A/V-S will provide clean and regulated power to the critical loads. The Series 700A/V-S should have the switch in the normal position unless a failure has occurred. BYPASS MODE With the switch in the bypass position, the Series 700A/V-S will provide clean power to the critical loads. In the bypass position, the unit will not regulate the incoming voltage. The Series 700A/V-S should be placed in the bypass position when a failure of the system has occurred. This provides the user with some protection until a service technician arrives. CAUTION PRIOR TO SWITCHING FROM ONE POSITION TO ANOTHER- TURN OFF THE AC INPUT BREAKER. REMOTE EMERGENCY POWER OFF (REPO) OPTION The REPO is operated by a remote push button that when depressed will shunt trip the Series 700A/V-S input breaker and disable the unit.

All Rights Reserved. 17 Installation Manual | Power Conditioner for Accuray CyberKnife® EQUIPMENT REQUIRED True RMS Digital multimeter, SCR tester, common hand tools, spare parts kit (contact service center at 1-800-882-9110 X 6112). STEP 1. DISASSEMBLING THE POWER LINE CONDITIONER A. Turn off the power to the Power Conditioner at its source. B. Turn off the input circuit breaker on the unit and the output circuit breakers to all loads. (Remove all loads from unit). C. Remove the front and side covers to the Power Conditioner. Refer to Diagrams in “Appendix A - Cabinet Layout”. STEP 2. ELECTRICAL CONNECTIONS, FUSES Refer to Diagrams in “Appendix A - Component Location Diagrams” for component locations. A. Inspect the unit for proper tightness of all electrical connections, burnt, frayed, broken or loose connections and components in these areas. Input and output connections, SCR assembly, SCR snubber, output filter assembly, MOVs (metal oxide varistors), circuit boards, bypass switch and transformer connections. B. Correct and tighten any loose connections, replace any physically burned or broken components. C. Check all fuses in system *. Time delay fuses, fan fuses, circuit board fuses, SCR fusible Link wire. POWER MODULES (SCR’s) Refer to the diagram below and the diagram in “Appendix A - Heatsink Layout”. 1. Unplug the connections to the control cards Part # 414921 labeled TB1, TB2 and TB3. 2. Disconnect any cooling fans in the unit so your SCR resistance checks are not interfered by fan motor coils. Each power mod contains 2 inverse parallel SCR’s. 6 1 7 3 2 4 5 3. Measure the following resistance on each power module. There are 7 per phase or 21 for all three phases. *Refer to the circuit diagrams received with your unit. 18 Note: When checking the power module assembly, if more than one defective power module is present it will appear as if all the power modules are defective. If this is the case, the individual power module must be isolated from the power transformer. 4. A. K1-1 to K2-1 thru K1-7 to K2-7=High resistance, 1 Meg Ohm. B. K1-1 to G1-1 thru K1-7 to G1-7=10 to 90 Ohms. K1-1 to G2-1 thru K1-7 to G2-7=1 Meg Ohm. C. K2-1 to G2-2 thru K2-7 to G2-7=10 to 90 Ohms. K2-1 to G1-1 thru K2-7 to G1-7=1 Meg Ohm. D. G1-1 to G2-1 thru G1-7 to G2-7=1 Meg Ohm. 5. Replace any defective power mods. This may require removing the shunt and loosening the K1 bus from all the power modules to get the defective power module out. Use only equivalent hardware and heat sink grease when replacing power modules. 6. If a resistance measure is questionable, a more thorough test will assure an SCR is good or bad by using the following test procedure. A. Completely isolate SCR under test by removing all connections to the device. B. Hook up the following test circuit to each individual SCR. C. Plug in SCR tester. With Switch #1 open light bulb should be off. If not, replace SCR. D. Close Switch #1. Light bulb should illuminate to about 3/4 brilliance. If not, replace SCR. SWITCH #1 7. Re-assemble the power module assembly, make sure all connections are tight. CHECK THE SCR SNUBBER CARD 1. Three components make up the SCR snubber. (Resistors, MOVs and Capacitors). Check for open resistors. Check MOVs for shorts, they should read high resistance when ohm meter is placed across them. Resistance check each capacitor. The DC resistance across the snubber capacitor should look capacitive-that is high resistance after the meter charges the capacitor. If it measures open or shorted, replace the snubber card. 2. Re-connect all wires and fans. Double check that all connections are secure. Do not connect TB1, TB2 and TB3 connectors from the control cards #414921 yet! © Smiths Power 2015.

All Rights Reserved. 23 Installation Manual | Power Conditioner for Accuray CyberKnife® SPECIFICATIONS SCOPE This specification covers the electrical characteristics of the Transtector Power Conditioner which provides clean regulated power for the entire Accuray CyberKnife.® GENERAL The Power Line Conditioner consists of a front access power cabinet incorporating an all copper, multiple tapped, triple shield isolation/ regulation transformer. The ultra low output impedance of the transformer in conjunction with the electrostatic shields assures precision hospital grade performance with excellent noise and transient attenuation. Independently controlled inverse parallel electronic switches for each of the 7 taps per phase provide tight regulation over a wide input range. Linear devices are used for line synchronization to prevent phase shift errors normally associated with simple CT zero current crossing acquisition. The microprocessor control accurately selects the correct tap to provide line voltage regulation of + 2.0% typical, correcting for voltage disturbances within one cycle. Digital processing technique provides fast and accurate regulation without output voltage over or undershoots.
