1 General Information  DANGER To avoid electrical shock from components under voltage, also be aware that: The capacitors of the capacitor bank can be electrically charged even when the system is switched off and the power cable is disconnected! Individual capacitors of the capacitor bank may have been disconnected from the discharging circuit, erroneously or as a result of failure, and can still be electrical‐ ly charged! Disconnect the battery blocks in the Mira to perform maintenance and service work! Carelessness can result in death or serious bodily injury.

   

n

Make sure that no parts or tools fall into the unit. Do not touch potentially dangerous components. If loose parts must be removed from the unit, use only insulated tools; Protect the work area so that no other persons are able to touch the unit while the covers are open or removed!

Switch the unit off before servicing or maintenance. Always disconnect the power plug first.

n

Make sure that the main switch is switched off.

n

The capacitor bank discharges to < 40 V in approx. 15 minutes

 The safety covers can be removed after this period has elapsed. n

V

Prior to performing any work, it must be verified that areas with dangerous voltage are voltage-free.

With housing covers open and safety covers removed. At the right side: CAUTION: DC voltage (400V) directly at the capacitor bank! At the front: CAUTION: DC voltage (400V) under a small metal cover at the discharging re‐ sistance of capacitor bank!

2 General Troubleshooting Information

2.3 Product-specific safety measures Prior to beginning system work, be aware of the following:

 DANGER Danger of life-threatening electric shocks. When performing maintenance or service work on the Mobilett Mira with the cov‐ ers removed, it is possible to come into contact with components under voltage. Carelessness can result in death or serious bodily injury.

 Before starting work with open covers, secure the working area so that no other persons can come into contact with the system.

 Remove safety covers only if absolutely necessary to perform a task. Then re‐ attach the cover correctly.

 Never leave the system unattended without safety covers. Do not employ any helpers without technical instruction. THINK CAREFULLY BEFORE TOUCHING ANY PART OF THE SYSTEM!

 When performing measurements and troubleshooting under voltage, comply with the general safety regulations for such work.

 Use the discharge resistor to safely discharge non-discharged capacitors.  Secure the system via the brake.  CAUTION Avoid contacting fault voltage on the unit. People must be protected against fault voltage

 After every work step when removing and installing parts of the unit, or dis‐

connecting and reconnecting system cables, a protective conductor test and a leakage current measurement should be performed.

2.4 Product-specific handling



Some trouble accrue caused by a non sufficient training or information of every user. The user manual is not designed for background knowledge of every detail. This chapter try to explain some basic steps of “best practical usage” the Mira system. When ever some trouble indicates causes by a non optimal or rough usage of the system try to inform a responsible person at the customer site how it could be possible to avoid services of readjustments or parts replacement.

2.4.1

System Power ON/OFF Mira “power ON” is organized by three main steps and corresponding functions: A) - Drive mode ON - main key switch from position 0 to 1 (permanent)

 After ~ 3 seconds the “Dead-man switch” at the handle bar react for driving. System battery powered to “free motorized driving” (fast mode) if: 1 - the mains cable is unplugged and stored (rolled up) 2 - the tube arm is locked in park position 3 - no Ethernet cable is plugged in B) - Generator ON - main key from position 1 to 2 and back to 1 (one time kick switch)

 After ~ 10 seconds the kV/mAs display light up. All generator functions for examination available / default “Digital” mode C) - Image system (FLC) ON Separate button -

 After ~ 80 seconds FLC- PC start up procedure Entire image system functionalists available (generator digital mode) Every step of the above described “power ON sequence” needs a certain time for initializa‐ tion. It’s recommended to wait always the mentioned time for initialization and respect this se‐ quence of A/B/C. Other wise an intermittent malfunction could appear like “FLC not ready” , “Waiting for FLC” etc. That caused by non synchronised initialization.

2 General Troubleshooting Information Power ON - Hints for usage: 1.) Respect the start up (power ON) sequence with the short waiting times for a sta‐ ble system function.



It’s meant for a startup workflow for a daily work start or a work shift after charging the system. 2.) For driving from a park position to an examination position is no need to have the FLC-PC ON. To prevent from damage the PC hard drive it’s good to have the PC OFF than running during driving on bumpy ways. It’s meant for longer distances e.g. from a park position for charging and change to an‐ other floor or department. In cases of standby near the examination place is no need for a PC shut down.

2.4.2

Driving / Stand by / Parking - Driving - The unit is build for smooth drive ways with inclines / declines of 7° max. (with maxi‐ mum speed). - Any bumpy ways or doorsteps, height differences of elevators or equal bumps and rough elements should pass over carefully with slow speed. - The FLC-PC is designed for short smooth drive ways but not for likely “off-road driving”. Often bumpy driving can cause errors and a decrease of the PC - lifetime. - Run into hard elements like doors, walls or other hard resistances can reduce the me‐ chanical life time of the single tank. Driving - Hints for usage: 1.) Drive carefully with slow speed while pass over steps, bumps or rough ele‐ ments .



Drive with foresight to remain of mechanical damages to the unit. 2.) Switch OFF the FLC-PC while driving through “long” distances. Prevent the PC hard drive against mechanical bumpy stress. 3.) Do not drive with the tube against hard elements as e.g. to open a door. Every beat against the single tank housing can cause damages, like leakage of the oiltank; misalignment of tube movement etc. Stand by Definition for Mira: - The unit is powered completely - Drive mode + generator + FLC = ON - Position of the unit is next to the place of examination to act as quick as possible (emer‐ gency / intensive care department). - The stand by position should provide a mains/line power connection. - During the time of not use the unit should be plugged in for system battery charging.

General Troubleshooting Information 2 - The wireless detector must be insert correct into the docking station (charge detector battery). - The unit position should be protected against any external bumps from other traffic like patient beds, other movable facilities.

For customer with a high level of stand by situations it is always recommended to have the “ECO - mode” activated. It will relieve stress from all involved components and give the chance of the longest life time as possible. (tube filament; capacitor bank; capacitor charging circuit). The wake up will be quick enough and will not limit the user to get an exposure as quick as required.

Stand by - Hints for usage: 1.) Keep the unit ready for quick usage near the place of examination.



Always look for a position were a main/line power connection is available and plug in for charging. 2.) Try to positioning the unit that no bumps are possible to the detector inside the docking station. Prevent the charging mechanism against damages. 3.) Do r Beats a.

2.4.3

Battery care System battery System battery = 4 lead gel batteries / 12V - 65Ah serial connected for 48V nominal. These batteries allow no deep discharging. Best care is loading every time when not used. System battery Hints for users: 1.) Any time if the unit is not in use plug to mains/line power for charging.



Always look for a position were a main/line power connection is available and plug in for charging. 2.) One time a day the system battery should be fully charged. Watch out for a parking position without traffic problems to the Mira. . Detector battery The detector battery is a lithium-ion battery / 10.8V 2.6Ah (28.1Wh) This battery needs a full discharge from time to time. Mira have a service program called “Battery calibration” or

2 General Troubleshooting Information is called “Detector battery conditioning”, too. It can be started out of the tab-card service with symbol of a battery. It’ recommended to do so approximately all ~ 2 to 3 month. Procedure takes ~6h time Detector battery Hints for users: 1.) Always watch out that the detector fits correct into the docking station.



The charging pins 2.) Use the “Battery calibration” when the detector seems to be rather down than usually. It should be planned for a ~6 hours non usable time of the unit. Remote control battery These are two “AAA 1.5V alkaline batteries”. Should be changed ~ 18 month. No extra care necessary The control will temporarily beep after ~2 minutes if it’s not placed correct back into the holder. Remote control battery Hints for users: 1.) Always place the control correct back into the holder after use.



As more often it’s not placed correctly the batteries will decrease in life time. 2.) Replacement when a reaction is not present by one short push of a button. Check it by usage the collimator light function.

2.4.4

Detector handling It’s trivial but not always respected. The detector technology is much more complex, sen‐ sitive and high priced than an ordinary film cassette even if it’s handled in the same way of the examination work flow. - A drop down, scratches to the surface or other rough usage is not tolerated in the same way as a film cassette. - After a wet cleaning of the detector contact side it needs a little time or an extra step with a towel to dry before replacing into the docking station - Keep the charging mecha‐ nism dry and free of corrosion. - Park - or stand by positioning the entire unit should be free of possibilities to get bumps from outside to the detector. - The charging technique needs to get one second reaction time of moving the pins away from the detector contacts.



2.) Cleaning before place back not with wrong fluids which generate corrosion to the contacts. Clean with soft cloth moistened water or a lukewarm diluted solution of water and dish‐ washer liquid only. Watch out that the contact surface is dry before place back to the docking for charging. 3.) Place back slowly - Do not let fall down the detector into the docking station. Placing it hardily down to any interim position will damage the detector frame. 4.) Observe the time of detector usage for examinations without charging. If it’s much less than usually schedule a detector battery calibration. Detector backup cable The backup cable is designed for rear special situations not for a high frequent usage. - First of all in case of an examination and the image doesn't appear at the screen - Rescue the last image. - Connection for Attachment & Detach when option detector sharing is in use. - Software upgrades, calibrations and other servicing activities. - It’s not made for use it connected while an examination is done.

 2.4.5

Detector backup cable Hints for users: 1.) Handle with care when plug in, remove and storage. Sensitive plug connection not designed for rough frequently usage.

Conclusion The next chapter “Mira handling compendium“ contains all above mentioned “Hints for users” as a kind of a “code of best practice” - memory how to use Mira optimal. Please use it as a training refresher, a help to check marks of usage and in case as a diplomatic re‐ minder to users.

4.1 Generator service usage



The generator service is managed by the image system PC (FLC) under the key words “Local Generator Tools ”. Do not mix up with the key words “Generator SSW” - not used. If it’s selected accidently exit the FLC-service and enter again.

NOTICE Beware of unintentionally moving basic system software data. When you use the touch screen functionality in the service menus, it is possible that you will unintentionally move files or folders to an unknown path. There is no notification of this on-screen. One possible outcome is that the next PC boot will fail. As a consequence, you must do a full restore using the most recent “good GHOST” DVD.

 Always use connected hardware -- a mouse and a keyboard -- for navigation in the service software.

Fig. 11: Keyboard and mouse



To change any generator values, the hardware “SERV.” button must be ON. Located on inside of the “service flap” on the front of the system (see the figure Generator_Serv‐ ice_Mode_ON)

Values in this chapter are not default or suggested values. Some values shown are based on: - Customized individual settings



- The options installed - Multiple Mira units installed - Detector sharing at the Customer's site - Age of the unit - National rules / regulations (such as: RöV§16; DHHS)



Adjusted values are saved to the generator CPU. In the event data are lost with a CPU board replacement or an upgrade to D810 firmware, there is no complete backup file for the most recent adjustment values. Suggestion: Use screen shots to capture various adjustments.

4.2 Taking screen shots



Taking a screen shot could be beneficial for several reasons: n Capturing default or adjusted data n

Documenting or logging any adjustments

n

Communicating with other departments or institutions

To take screen shots, you must have a (non-wireless) mouse connected.

Fig. 13: Taking screen shots

Taking screen shots: 1. Right-click (using the mouse) the small encircled letter "i" in the lower right corner of the FLC application screen 2. Left-click the checkbox “create screen dump” 3. Left-clicking the OK button onscreen will produce a .bmp image file. This file is auto‐ matically saved under:

 Explorer partition: C:\FLCompact\Log\Screen dumps  Filename example: Screenshot_20090930_122144.bmp



The folder “Screen dumps” is not part of the FLC backup. If any file is to be used for documentation or logging, it must be copied to an external data device for archiving or communication ( a print out for the system binder; CD/DVD for image quality confirmation or start up protocol).

The adjustment should be done in coordination with a responsible user. The goal is to find out the driving characteristics best suited to the area where the unit will be mainly used. During the initial startup, demonstrate the different drive adjustments to the responsible user and offer a drive test for making a final decision. Only one combination will be stor‐ ed and usable. Adjustment suggestions: n

D890_R5 hardware switches “HARD / SOFT”

 SOFT - most preferred configuration / Drive behavior seems to be easy to move and reacting sensitive.

 HARD - behavior as boards with revision level R4 / Seems to drive with human arm power and reacting harder.

n

Mostly longer distances ( building to building)

 Transport speed = High / Turn Compensation 1 to 4 (less sensitive) n

Small rooms with difficult maneuvers ( intensive care rooms)

 Transport speed = Middle or Slow / Turn Compensation 4 to 9 (more sensitive) n



The final movement behavior adjustment is a user decision.

In case of a part replacement or update of the firmware for the motor control board (D890), the user-decided values are deleted and need to be re-configured.

4.12 Board Firmware Upgrade Fig. 70: Firmware upgrade



All board upgrades require the “SERV.” button to be activated. There are 3 different upgrade procedures. Part of the board functionality. Upgrade procedures 1. Simple installation for D820 / D830 / D850 / D860 / D890 (slave of CPU) 2. D848 Power distribution - different power supply organization cause for power man‐ agement. 3. CPU D810 "Master FW" - for generator control needs a different LIN-Bus management during the upgrade



The installed FW file could be an older or newer one than the one stored in FLC explorer. If the update failed there is no way to go back to the previous FW file. Unless a backup ghost file of partition \\C: is available. When you click on the “Firmware Upgrade“ button onscreen, a black window with “+ C:” will be displayed. Navigation is similar to WINDOWS Explorer. Step by step for each board.

5.1 Basic function

5.1.1

System ON/OFF (park/ standby/ Eco mode/ drive) All these functions should be tested according the user manual SPR8-260.620.01...

5.1.2

TFT displays (touch screen) Sometimes users complain of insufficient reaction by the screen buttons. 1) Sensitivity One reason or possible solution could be in adjusting the touch screen sensitivity. It should be adjusted to the 16 or 25 point calibration. Refer to the replacement of parts ( Performing touch calibration / XPR8-260.841.01) The main problem seems to be failing to center the finger exactly on the screen button of interest. 2) Cleaning sequence In another case, the user felt the on-screen area of interest had to be pressed hard or more than once for a reaction. This is mostly due to cleaning of the touch screen surface. The requirement is the man‐ ual: “...should be cleaned at least every two months”. That is far too little a touch screen. It should be cleaned at a minimum every two days of regular use. 3) Cleaning agent One more reason could that the regular cleaning is with a damp cloth and water only. Af‐ ter a while this will produce a thin film on the surface (a mix of water and oils from the fingers). - Clean the screen with an damp cloth dipped in alcohol and advise the user to clean it in the same way on a regular basis. - Instead of using a finger, try a “touch screen stick” (works cleanly and is more exact than fingers).

If LED V4-D820 lights up, then proceed as follows: - Switch the unit off, disconnect D810 X13, X20 and X22. Reconnect X10 and switch the unit on again. If LED V4-D20 lights up, connect X13 and check LED V4. If it does not light up, the problem is cable x13 or board D890 (control motor). If it lights up, connect the next cable X20, if does not light up, the problem is cable x20 or board D850 (capacitor charger). If it lights up, connect the next cable X22. If it does not light up, the problem is cable x22 or board D860.
