1.1 Important Notes

• The ORTHOPHOS® 3 / 3 Ceph / 3 DS operates with the following nominal line voltages: 208V, 230-240V, 50/60 Hz. The permissible line voltage fluctuations The internal line resistance

• Remote control The unit can be equipped with a remote control inside the treatment room or outside an X-ray room. For the tests the Multitimer can/must be removed from the remote control module and is to be connected directly to the

unit (for remote control with the Multitimer without coiled cable, the coiled cable has to be connected for the tests according to the installation instructions).

Remember that the fault can then be in the deactivated cable.

• Warm-up time, self-adjustment, cool-down time, After power-up the unit always requires a warm-up time of one minute.

During this time, the self-adjustment routine for the mechanical elements and electronics of the unit is executed. Pressing a key during the self-adjustment causes an error indication at the Multitimer. The cool-down time between two consecutive exposures is ensured by the automatic exposure blockage determined by the pulse/pause ratio. The count down of the waiting time required is indicated on the Multitimer. The turn-off time of board XAB-OP must be at least 60s; otherwise the unit will not function correctly (no exposure readiness).

• For demonstration units Now, no X-ray radiation is generated. In the interest of improved safety we recommend removing fuse F5 on board DX3.

• The overall software v ersion Multitimer D4 as well as the version number of the memory card. Refer to the list of software versions. When switching the unit ON the versions are indicated on the Multitimer for about three seconds after the segment test.

• Interference of radio telephones with electromedical equipment The use of mobile telephones in the area of the medical practice or clinic is prohibited in order to ensure the

operational reliability and safety of electromedical equipment.

• Disposal The X-ray tube assembly contains a tube which can implode, a small amount of beryllium, a lead lining and mineral oil.

• Error messages Error messages are indicated on the Multitimer.

1.1 Important Notes

• If you have to remove panels from the unit. Refer to section "Removing panels". With the panels removed, remember that the direct incidence of sunshine or bright room light can cause unit malfunctions

by activating the light barriers.

Therefore: Avoid direct sunshine and bright lighting above the unit

Remember when reattaching the panels: Secure sheet metal covers with screws.

IMPORTANT: For reasons of EMC it is essential Reinstall all panels.

• Measurements Before connecting a measuring instrument, always switch the unit OFF. Select the required current/voltage type and set the measuring range according to the expected value. Carry out continuity tests only with the unit switched off.

If the release of several exposures with radiation is required for checking the measuring results, you must observe the specified cool-down intervals. This is ensured by the automatic exposure blockage (see Operating Instructions).

The pulse/interval ratio is 1:10, which means a 10 second pause has to follow after 1 second of radi ati on. This pul se/i nterval ratio is automatically guaranteed by the automatic exposure blockage.

However, preferable for the X-ray tube is a pulse/pause ratio of 1:20.

Adhere to the radiation protection guidelines before generating radiation.

Test runs initiated by pressing the T key on the Multitimer followed by actuation of the exposure release button are executed without radiation, i.e. the kV/mA displays remain blank. l

to insert all screws.

• Replacing parts Always turn the unit OFF before replacing any parts.

When parts located close to the line transformer are to be replaced, switch off the power at the distributor box for the onsite electrical system for safety reasons WARNING! The discharge time for the capacitors is 4 minutes.

To protect electrostatic sensitive devices (ESD) on boards, always wear the wrist band.

The unit must be checked and newly adjusted following the replacement of the DX1 electronics, the X-ray tube assembly or a diaphragm.

The article numbers for ordering spare parts can be found in the spare parts list, order no. 33 33 908. The figures in the spare parts list offer valuable assistance when replacing parts.

2.1List of Help Messages

After the cool-down interval has elapsed you want to release an exposure, but the Ready LED is flashing:

• Press the X-ray key on the Multitimer.

CAUTION: Take radiation protection measures.

The H3 or H4 message then appears on the kV/mA display.

• Find in the following list the actions required to return the unit to readiness for exposure.

• Before

carrying out the required action clear the help message

Description

Interruption caused by releasing the X-ray button on the Multitimer during radiation.

Interruption caused by releasing the X-ray button on the Multitimer between two partial exposures.

Interruption by OP. Check error message on Multitimer.

Voltage problem/failure at image receptor, see Appendix A.

Timeout on the XOP/XAB, no defined functional call from OP within a preset time. (only for ORTHOPHOS Plus DS Ceph)

Incorrect communication between XOP/ XAB and image receptor.

OP pulses are more than intended for the exposure.

Image acquisition card holds insufficient storage space for the intended exposure.

Image acquisition card receives no image information.

ORTHOPHOS emits incorrect exposure ID. Check the software versions of OP and

The displayed number XXX is an indication of several error numbers, see Appendix A.

Check for mechanical obstruction of the OP movement. Check the software version of OP and SIDEXIS for compatibility.

Remove the image receptor from its holder and reinsert it firmly. Check signal path with XOP: XOP – cable connection – OP – image receptor. Check signal path with XAB: XAB – image receptor. Check the voltages at the image receptor.

Check the software versions of OP and SIDEXIS for compatibility. Check whether OP is "hung up".

Check the software versions of OP and SIDEXIS for compatibility. Check the memory configuration of XOP/ XAB.

Remove EDC from its holder and reinsert it firmly. Check the signal path: Check signal path with XOP: XOP – cable connection – OP – image receptor. Check signal path with XAB: XAB – image receptor. Check the voltages at the image receptor.

SIDEXIS for compatibility. Check the error message displayed by the OP. (data or address bus error?)
