12.2. TECHNICAL MAINTENANCE
These instructions describe the maintenance procedures for the extraoral X-ray system. These instructions apply to all versions 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 any parts.
Answer questions with yes (√) or not (−)
Inspection DATE
Step Description Reference in the manual __/__/20__ __/__/20__ __/__/20__
1
Check that all labels located
-
on side of the device
- at the base of the column,
- on the X-ray tube housing,
are intact, well attached and legible.
User Manual, Section Identification plate position
2 Check there are no external damages to the equipment, which may reduce protection against radiation. User Manual, Section Description of operation
3 Check the remote emission button cable is not broken or scratched. User Manual, Section X-ray emission remote control
4
Check the power switch verifying that the switch is working properly and the green light on the switch, check if the keyboard
illuminates when the switch is in the on position.
User Manual, Section Starting the system
5 Verify that exposure is immediately interrupted when x-ray button is released User Manual, Section X-ray emission remote control
6 Check the control keyboard functionality: functions must respond to interrogation. User Manual, Section Console onboard the machine
7 Check proper functioning of X-ray exposure LED and exposure buzzer User Manual, Section X-ray emission remote control
8 Check proper functioning of patient centring laser traces User Manual, Section Laser traces
9
Perform a movement test running the Dummy panoramic procedure, making sure the axis movement (rotation and translation
simultaneously) is smoothly and without noise. See figure 1, next page.
User Manual, Section Perform a simulation (Dummy Run)
10 Perform column movements, up and down on the Z axis and check proper functioning. See figure 2, next page. User Manual, Section Console onboard the machine
11
Check the emergency stop button functionality. Emergency stop button is used to stop X-ray device operation, it is located at the
top near mains switch button.
User Manual, Section Emergency stop button
12
Check the x-ray generator functionality performing a complete trial exposure. Select any panoramic exam and reset the unit. Hold
down the emission button throughout the entire exam procedure. Absence of error messages assures proper generator
functionality.
