DANGER
Potentially lethal shock hazard!
It is essential to switch off the unit and wait at least 1 minute before removing a cover.
Switch OFF the X-ray unit before connecting a measuring instrument.
Perform continuity tests only on units which are switched off.
NOTICE
Risk of damage to unit
Select the correct current/voltage type and adjust the measuring range to match the expected readings.
Keep to the prescribed cool-off periods if several exposures have to be taken to check a measured value.
Please observe the usual precautionary measures for handling printed circuit boards (ESD). Touch a ground point to discharge static electricity before touching any boards.
CAN bus cable: When unplugging CAN bus cables, it is essential to unplug the power supply as well.

Checking the CAN bus
NOTICE
Risk of damage to unit
The power supply MUST be plugged in and switched on when cables are attached and plugged in. For example, if no power cable is connected to the DX71, the module has no ground connection to the unit and there is no potential equalization. If the CAN cable is plugged in, the
CAN transceiver (IC on the DX71) can be destroyed by the voltage difference. In other words, when the unit is switched on, CAN cables may only be plugged in on modules that are connected to the power source and ground.
For troubleshooting, you can disconnect the CAN bus cable and/or plug it back in and observe the (unit's) behavior.

6.2 Checking the CAN bus
6.2.1
Checking the CAN bus with the diagnostic function of board DX1
Checking the CAN bus with the diagnostic function of board DX1
Board DX1 features a diagnostic function for diagnosing malfunctions of the CAN bus via LEDs V700 and V701 (see wiring diagrams). The following table indicates the operating status of the CAN bus and the recommended error correction measures:
V700 V701 CAN bus operation
Slow flashing Slow flashing CAN bus OK
Fast flashing Off CAN error, no communication with board DX7, i.e. no display of error messages
Fast flashing Fast flashing CAN error, no physical communication with CAN bus possible; there is probably a short circuit in the CAN cable or on the board of a module.
Off

CAN error, CAN bus TTP (time trigger protocol) disturbed by defective, constantly transmitting board (busheavy).

Error correction
Not required
● Check cabling.
● Check CAN jumpers (Jumper positions in the CAN bus [ → 125])
● Disconnect CAN cables one after the other (set jumpers to inner position!) until the CAN bus functions again
(V700 and V701 flash slowly).
Replace faulty module.
● Disconnect CAN cables one after the other (set jumpers to inner position!) until the CAN bus functions again
(V700 and V701 flash slowly).
Replace faulty module.
Switch unit off and on again and wait until end of power-on time.
6.2.2
Jumper positions in the CAN bus
Jumper positions in the CAN bus
The jumpers are located on board DX1 at sockets X302, X303, X306,
X307, X309, X500, and X503 (see also wiring diagrams). If a cable is connected to the socket, the corresponding jumpers must be set to the outer position. If no cable is plugged in, the jumpers must be set to the inner position. If a jumper is set to the inner position without a cable plugged in, the CAN bus is interrupted at this location. Modules located behind this location can no longer be connected to the CAN bus and, therefore, do not function.

Fault diagnosis of the X-ray detector and on board DX89
Fault diagnosis of the X-ray detector and on board DX89
NOTICE
Do not damage the image tube!
The image tube of the X-ray detector is sensitive to mechanical stress, and therefore must be handled with extreme care. Avoid bumps and jolts. Please consider this point during transport and installation.
For error messages in connection with board DX89, it is important to determine whether the fault concerned is attributable to a defect on board
DX89 or to a defect in the X-ray detector. To do this, proceed as follows:
1. Move the unit down using the Up/Down keys.
2. Switch off the unit.
3. Remove the x-ray detector cover.
4. CAUTION! Risk of injury! The cover plate has sharp edges.
Carefully pull the cover plate upwards to remove it from the X-ray
detector (see also Replace X-ray detector [ → 279]).
5. WARNING! Potentially lethal shock hazard! Do not touch any live parts while observing board DX89.
Remove the cover plate of board DX89. Switch the unit on again and observe board DX89.
The LEDs on the board can provide information about the possible
cause of the error (LEDs on board DX89 [ → 141]).

NOTE: In x-ray detectors with a serial number
≥5000, cable L28 cannot be replaced.
If all LEDs light up after the power-up phase, this indicates that there is a defective FPGA on board DX89. For troubleshooting, see the action under "LED OFF for PLL_FPGA".

● Replace the X-ray detector [ → 279].
The free ions are pumped out of the vacuum of the X-ray detector by the getters (hence the name "getter pump"). The getter current is measured during operation. If this does not drop below a certain value within 12 minutes, the gettering is not o.k. In this case, the error is probably caused by a defective x-ray detector.
