See the hazard matrix in the following Energized Electrical Work Procedure for specific PPE relative to energized electrical work.. Energized Electrical Work Procedure Note:. All electrical circuits or energized parts shall be de-energized and rendered safe using the appropriate Lockout/Tagout (LOTO) procedure, unless energized system testing, positioning, or adjustment is required. When energized work is required, this procedure must be used – inconvenience is never acceptable.. Definitions NFPA 70E – is a national consensus standard that forms a “Standard for Electrical Safety in the Workplace.” It is also a part of the National Electrical Code, which has been adopted by OSHA as an enforcement standard. Arc-flash – an explosion of electrical energy that can cause burns and other injuries. An arc-flash is essentially a short circuit through the air. Qualified Individual – an authorized employee who has been properly trained and certified (verified) to work on energized equipment. Anyone not meeting these requirements is an un-authorized individual.. Purpose To mitigate the electrical safety hazards (arc-flash) associated with energized system testing, positioning, or adjustment (calibration) of GEHC/OEC equipment - in accordance with the NFPA 70E consensus standard.. Training Requirements It is the obligation of each GE Field Service Engineer to follow this procedure and understand that failing to do so can cause serious injury or death.

(18) Safety. Lock-Out, Tag-Out This procedure meets the basic LOTO requirements established by OSHA and follows the policy of GE Healthcare for energy-isolation during the service/maintenance of this equipment. It is designed to insure that each employee involved in servicing this equipment has exclusive control over when the equipment is reenergized (i.e. each employee maintains a personal lock with a unique key). It is the obligation of each employee to follow this procedure and understand that failing to do so can cause serious injury or death. Only Field Service Engineers who have complete LOTO Authorized and initial LOTO Verification training will be permitted to execute Lockout/Tagout on this system. All other non-authorized individuals will be considered “affected” individuals.. Specific Sources of Energy TYPE. SOURCE. MAGNITUDE. STORED. Electrical. Facility. 120 VAC. NO. Electrical. Batteries. 225 VDC. YES. Electrical. Capacitors. 225 VDC. YES. Gravitational. Potential (C-arm). ~ 50 lbs.. YES. Mechanical. Potential (L-arm). NOTE:. ~ 1100 lbs.. YES. When servicing the Workstation alone, the system is considered a single energy source if and only if the C-Arm is disconnected (by removing the Main Interconnect Cable) and the power cord is under the exclusive control of the authorized employee performing service. As long as the authorized employee can retain exclusive control over the power cord, the 120 VAC electrical energy source can be considered controlled and service can proceed. If at any time service involves maintenance of the C-Arm, the following “Energy Control Procedures” are mandatory and must be implemented by authorized Employees.. Energy Control Procedures 1. Notify all affected individuals of a shutdown. 2. Verify safety of work area. 3. Identify all electrical sources. 4. Position C-Arm for service. 5. Shut down system via green main power switch. 6. Remove A/C plug from wall power.. 9.

(19) Safety. 7. Remove interconnect cable from C-Arm. 8. Apply the red lock and tag to the AC plug as shown in the figure below.. 9. Remove workstation rear and side panels. Disconnect J10 from the ISD board. (This isolates AC power coming from the UPS). 10. In the workstation verify zero volts AC at TB1 between the brown and blue wires. 11. On the C-Arm turn off battery circuit breaker CB1 located under the front right side below the power cap module.. 10.

(20) Safety. 12. Remove C-Arm covers.. 11.

(21) Safety. 13. At the top of the power cap module disconnect red and black battery connectors. Verify zero volts DC across previously removed red and black battery connectors. 14. Power is now locked out. NOTE:. In the event service will continue into another day, and/or the machine will cause a hazard if reenergized after the authorized employee leaves the location, leave the A/C cord cover installed with a “transition” lock and yellow tag attached. If more than one authorized employee is going to conduct service on the same system, at the same time, multiple locking devices must be employed and each authorized employee must adhere to the entire LOTO procedure.. Testing and Positioning During Service In the event that lockout/tagout devices must be temporarily removed from the energy isolating devices, for testing or positioning purposes, the following sequence shall be followed:. 1. Clear the machine of tools and materials. 2. Ensure that all employees/individuals in area are safely positioned or removed. 12.

(22) Safety. 3. Remove energy control measures. 4. Energize system and proceed with testing or positioning. 5. De-energize system and reapply energy control measures.. Restore Power After Service 1. Re-inspect work area for hazards. 2. Reconnect red and black battery connectors to the power cap module 3. Reinstall C-Arm covers. 4. Turn on CB1 on the C-Arm. 5. Install workstation covers. 6. Connect main interconnect cable to the C-Arm. 7. Notify all affected personnel that power is being restored. 8. Remove red lock and tag 9. Energize the system. 10. Verify proper system operation. 11. Inform customer that system is ready to be returned to service.. WARNING:. High voltage cables, electrolytic capacitors, and CRTs can retain a dangerous static charge for long periods after power has been removed. Some devices can acquire a charge spontaneously without direct contact with other circuitry. Do not touch these components unless power has been completely removed and they have been discharged. Equipment that contains high power electrical components must be serviced only by personnel familiar with proper safety procedures for working near these components. Disconnect AC power (and battery packs if used) before discharging static electricity in components such as electrolytic capacitors and high voltage cables. Failure to heed this message will result in death or severe personal injury. Allow adequate time for static charges to discharge through bleeder resistors. Use a high wattage resistor when discharging circuits to avoid burns. Have someone watch while you work near high voltages. This person must remain clear of all circuitry and be prepared to turn off the power to the system and render aid in an emergency.. WARNING:. Systems with battery packs can deliver high currents at high voltage. Electric shock from batteries can cause death or personal injury, including severe burns. Use extreme caution when working on circuits energized by or located near the batteries. Batteries are dangerous at all times. Setting the battery pack circuit breaker to off removes battery current from other circuitry, but does not render the batteries harmless.. 13.

(23) Safety. CAUTION:. Never operate the system unless all potential equalization conductors (green wire with a yellow stripe) and related components are fastened in place. Dangerous electrical shock and improper equipment operation can result.. CAUTION:. Remove all metal rings and watchbands before working on system circuitry. Skin burns and damage from involuntary muscle contractions can result if metal jewelry shorts electrical circuits.. 14.

(24) Subsystem. Subsystem All Workstations, including non-NAV Workstations, should now be fitted with an uninterruptible power supply (UPS) as standard equipment. The block diagram below, as well as the following sections, reflects this change.. Workstation Block Diagram with UPS The following block diagram shows how the Workstation SBCs interface with the other Workstation devices over the dual passive backplane.

(25) Power Distribution and Control. Power Distribution and Control Intelligent Shutdown Power Control PCB (ISD-PC2 PCB) The Intelligent Shutdown (ISD2) Power Control PCB prevents the system from powering up if the AC line power is faulty or if applying AC power to the system would create a condition that is dangerous to the operator or the equipment. For example, if the Lemo connector is disconnected from the C-arm Lemo jack, it is not possible to power up the C-arm because AC power in the Interconnect cable is disabled to prevent electric shock. Through the uninterruptible power supply (UPS), the ISD Power Control PCB can also prevent premature shutdown of the system and data loss during a power failure or accidental shutdown. The ISD protects the Workstation in the following ways: • Controls the application of AC power to the Workstation electronics and accessory outlet strip. • Controls the application of AC power through the Interconnect cable to the C-arm. • Prevents the application of AC power to the C-arm when the Lemo connector is unplugged from the C-arm. • Senses AC mains applied voltage at power-up. Inhibits power-up if line voltage is out of range and sounds an on-board alarm to alert the operator or field service engineer. Operates LEDs that display power condition. Green LED DS1 glows when AC line voltage is OK. Amber LED DS2 glows when line voltage is too low. Red LED DS3 glows when line voltage is too high. • If you press the Workstation power switch to turn it off, and main AC power is still available to the Workstation, the system will not shut down until system software determines that all data-preservation steps are complete and it is OK to shut down. • Under software control, K9 on the ISD2 selects either unprotected AC from the AC line or battery-protected AC from the UPS to power the Workstation. • Provides status information to the Workstation software through the System Interface PCB and receives power-control commands over the same path. • Causes Workstation power switch to flash when you turn the Workstation off. The flashing continues until shutdown is complete, at which point the switch lamp turns off. • Interfaces with the UPS Off switch, which operates relay K9 to disconnect the UPS output from the Workstation. • Generates the UPS Off signal through K10 to turn the UPS AC output off.. 16.

(26) Power Distribution and Control. Uninterruptible Power Supply Workstations have a 230 VAC-operated uninterruptible power supply (UPS), which generates modified sine wave 230 VAC from an internal battery-powered inverter if the AC line fails. This enables orderly system shutdown during a power failure so that no important patient data or images are lost. The UPS also protects the Workstation from power sags, power surges, brownouts, and line noise. Other important features of the UPS include the following: • Battery-management software that effectively doubles the battery service life. The software optimizes battery charging and provides advance warning of impending battery failure. • Buck and boost voltage regulation that corrects AC line voltage fluctuations. • Start-on-battery capability that allows you to turn on the UPS even if the AC line power is not available. • Accepts control signals from external equipment. The Workstation UPS mounts inside the Workstation just above the transformer pan and has a capacity of 1400 VA. It appears as follows:. Workstation UPS. 17.

(27) Power Distribution and Control. Front-Panel Controls and Indicators The UPS front-panel controls and indicators shown below are accessible behind the right Workstation cover (viewed from the front of the Workstation). The UPS external circuitry appears on sheets 4 and 5 of Interconnect Diagram 885899. When the Workstation is on, the ISD-PCB supplies a low on P12-2- to pin 3 of the UPS communication port, turning the UPS on. When the UPS is on, it supplies AC power to its rear-panel receptacles by switching AC power from its input connector. The AC power at the input connector comes from the ISD PCB. After the UPS is on it conducts a self-test, and if all is well it enters Normal mode. The green Power On indicator glows, indicating that power is available from the UPS rear-panel receptacles. If the AC mains power fails, the UPS supplies power to the system using its internal battery and inverter. The green Power On indicator goes out and the yellow On Battery indicator comes on. An audible alarm sounds. The UPS receives AC power whenever the system power switch is on. The battery recharges if necessary. Refer to the UPS Fault Indicators table at the end of this section for more information on how the UPS front-panel controls and indicators behave in various error conditions.. UPS Front-Panel Controls and Indicators. 18.

(28) Power Distribution and Control. Rear-Panel Devices The following illustration shows the rear panel of the UPS. You must remove the Workstation front cover, the two screws securing the strap, the UPS corner bracket and slide the UPS out to the right to gain access to this panel.. UPS Rear Panel Devices. Communication Port The ISD board connects to the UPS communication port. This enables the system to turn the UPS on or off. The pinout for the 9-pin D-sub connector appears below.. Communication Port. 19.

DIP Switches The two DIP switches next to the communication port configure the UPS for the proper input voltage range. A switch in the up position is on and in the down position is off. Normally, you will not have to adjust these switches unless you are replacing the UPS. Verify output voltage setting is 220V UPS Rear-Panel DIP Switches Output Voltage. Input Voltage Range. DIP Switch 2. DIP Switch 1. 220*. 198–233. Off. On. 230. 207–243*. Off or On. Off. 240. 216–254. On. On. *Factory setting. Network Transient Protector (Not used) The network transient protector is not used in the Workstation UPS.. 10A Receptacles The six IEC-320 230 VAC receptacles together have a maximum current capacity of 10A. WARNING:. 20. Do not connect any other devices to the UPS receptacles..

(30) Power Distribution and Control. Input Connector Supplies 230 VAC to the UPS.. Cooling Fan The UPS fan and Workstation cooling fans must operate at all times the system is on, or the Workstation will overheat.. UPS OFF Switch The Workstation has a UPS OFF switch, which enables you to turn the system off manually even if the UPS is currently powering it. CAUTION:. This switch turns the system off immediately without the protection of software controlled shutdown. Because there is risk of data loss or corruption, use this switch to turn off the system only when absolutely necessary.. The UPS OFF switch is located on the rear panel of the Workstation. There is a clear plastic protective panel over the switch, that you must lift before operating the switch. If AC line power is available, an LED behind the switch lights when you press the switch. If the Workstation is being powered by UPS battery power, the LED lights and the ISD -PC2 alarm sounds until power is removed. The LED and alarm serve as reminders if the UPS Off switch is still engaged when AC power returns.. 21.

(31) Power Distribution and Control. UPS Off Switch Refer to sheets 4 and 5 of Interconnect Diagram 885899 and to sheet 3 of ISD PC2 Schematic 887456 when reading the following description of the UPS Off switch. After the system boots completely, the system routes AC line power through the UPS to the Workstation. This permits a rapid switchover from AC line power to UPS power in the event of a power failure. K9 energizes after bootup and remains energized if AC power fails. CAUTION:. When the system operates on UPS battery power it may become necessary to shut the system down immediately to prevent equipment damage, even though some loss of data may occur.. Press the normally closed UPS Off switch on the back of the Workstation to accomplish this. Pressing the UPS switch causes P11-5 to go high. This turns on transistor Q10, pulling the UPS_SEL line (U8-7) low and de-energizing relay K9. This shuts off power from the UPS. When P11-5 goes high, it also lights the UPS Off lamp if battery power from the UPS is still available.. 22.

(32) Power Distribution and Control. UPS Functional Tests Uninterruptible Power Supply Self-Test. CAUTION:. Removing the Workstation's covers in the following step exposes high-voltage points within the Workstation. Avoid contact with these points as you perform the following procedure.. 1.. Remove the front, side, and rear Workstation covers as described in the Replacement section of this manual.. 2.. With the workstation plugged in and not powered up, press and hold the Test/Alarm Reset button for three seconds to initiate a self test. The UPS automatically distributes the load to the batteries for 15 seconds and tests the battery’s performance. If there is a problem with the battery, the On Battery indicator glows and the Service indicator flashes. Check the battery connections and be sure that the battery is fully charged.. Uninterruptible Power Supply Battery Test The UPS inside the Workstation can power the Workstation for a limited amount of time when the system loses AC power. This allows the operator to shut down system operation in an orderly way to avoid the loss of patient images and data. The UPS uses an internal sealed lead acid (SLA) battery as the primary source of power during power outage emergencies. The SLA battery powers an inverter inside the UPS, which generates AC power for the Workstation. Note:. The C-arm shuts down immediately when the Workstation loses AC power. It is not possible to generate X-rays during a power outage.. The AC line supplies charging power to the UPS internal battery charger as long as the Workstation's AC line plug connects to an active AC outlet. Circuitry inside the UPS turns the charger on and off as necessary to keep the UPS SLA battery charged. The following procedure tests the UPS battery only. It does not test any other circuitry inside the UPS or elsewhere. 1.. Make sure that the Workstation has been plugged into an active AC outlet for at least 3 hours. If not, plug the Workstation into an active outlet and wait at least 3 hours before performing step 2.. Note:. If the system has been in long-term storage, you should charge the UPS batteries for 6–24 hours.. 2.. Power up system as described in Workstation Operator Manual.. 3.. Disconnect the USB connector J22 from the top of the electronics box at the rear of the workstation.. 23.
