Technical Maintenance - Myray hyperion X5 Manual De Operador

12.2. TECHNICAL MAINTENANCE

These instructions describe the maintenance procedures for the extraoral X-ray system. These instructions apply to all the revisions of said equipment.
In order to ensure the operational safety and functional reliability of the equipment installed, at least once a year an authorized service technician must perform a full inspection of the device.
When taking measurements that require a multimeter, always use a calibrated digital multimeter.
All the following tests will be carried out. Customer should be notified prior to replacing parts.
Step
Check that all labels located
- on side of the device
1 - at the base of the column,
- on the X-ray tube housing,
are intact, well attached and legible.
2 Check there are no external damages to the equipment which could reduce protection against radiation.
3 Check the remote emission button cable is not broken or scratched.
Check the power switch verifying that the switch is working properly and the green light on the switch, check if the keyboard
4
illuminates when the switch is in the on position.
5 Verify that exposure is immediately interrupted when X-rays button is released
6 Check the control keyboard functionality: functions must respond to interrogation.
7 Check proper functioning of X-ray exposure LED and exposure buzzer
8 Check proper functioning of patient centering laser traces
Perform a motors movement test running the Dummy panoramic procedure, making sure the axis movement (rotation and
9
translation simultaneously) is smoothly and without noise. See figure 1, next page.
10 Perform column movements, up and down on the Z axis and check proper functioning. See figure 2, next page.
Check the emergency button functionality. Emergency button is used to stop X-ray device operation, it's located near main switch
11
button.
Check the X-Ray Generator functionality performing a complete trial exam exposure. Select any panoramic exam and reset the
12 unit. Hold down the emission button throughout the entire exam procedure. Absence of error messages assures a proper
generator functionality.
Perform a complete 2D calibration of the unit : column calibration, PAN x-ray alignment, PAN detector calibration, PAN mechanical
13
alignment, Laser test.
14 At the end make a 2D calibration backup
15 ( Only for 3D machines ) Perform a complete 3D calibration of the unit: Beam limiter test, Daily check, Phantom acquisition cylindrical test.
( Only for 3D machines ) At the end make a 3D calibration backup
16
( Only for 3D machines ) Perform an exam on the 3D Quality Phantom and evaluate the quality of the outcome volumetric study.
17
The undersigned confirms that he/she has checked the unit for the above criteria and that he/she has handed over the unit in fully functional condition.
All inspection and maintenance work performed by the system owner and/or service engineer must be recorded in this document and kept near the unit!!
