General information 1

General information 1

Before starting work, make sure that the part number of the monitor corresponds with the
number of the instructions.

• Type X2080 monitors can be operated at 100 and 120 Hz and type X2079 at

50/60 Hz without changing the video standard.
Voltage: when delivered = 230 V +10% / -15%
(can be switched to 115V+10% / -15%).

• The monitor is adjusted wi th a functioning Memoskop. If this is no t available, the test

pattern of the Multinorm tes t box (refer to "Measuring inst ruments and auxiliary
devices"), the corresponding digital system, or the Videomed D can be used, if
necessary.

• Except for the luminance, adjustments are required only aft er replacing a module or

picture tube.

• The maximum luminance influences t he image quality to a considerable ex tent. If after a

lengthy operating time, t he luminance does not attain a maximum of

,

• When adjusting luminance, che ck the luminance of the second monitor as well.

Service 1

Repairs are limited to replacing modules.
Individual parts for PC boards are not avail able.
Parts available for delivery are shown in the spare parts list.

• Test templates are inc luded in the appendix. Their purpose i s to simplify service. The test

template is fastened onto the picture tube to adjust the image geometry. If the image
geometry is correctly adjusted, t he intersections of the grid li nes must be located within
the rings. Otherwise, adjust the imag e geometry in accordance with Chap. 4.

CAUTION

Safety information 1

Re: DHHS requirements

• DHHS requirements are met via factor y adjustment of the PC boards.

- Do not replace components or make circuit modif ications on the PC boards.
Always replace PC boards when servici ng the system.

- After replacing the power pack board SV1, check the voltage U = 48 V
TP “9”.
Ensure compliance with the tolerances.
This ensures compliance with DHHS requirements.

• Protection: IEC 601, protection class I, (with protective conductor)

unit type B IP 20 with reinforced insulati on for
primary/secondary (4 kV).

± 0.5 V at

• Interference

suppression:

acc. to VDE 0871, Part 2, limit value B,
acc. to VDE 0871, Part 3, interference suppression grade N,

• Comply with the safety-t echnical information in TI 236 “Safety regulations for installa tion

and maintenance.”

• Check that the monitor mounti ng and hardware are secure and show no signs of

damage.

Disconnect the power plug before removing the cover. Electric
shock hazard exists when the unit is still connected.

Observe the safety instructions accordi ng to theTI folder Register 2 (replaced by ARTD,
Part 2, ARTD-002.731.12.01) due to the risk of implosion of the picture tube.

When handling PC boards, observe the ESD directives according to TI 219.
To comply with EMC regulations, ensure that shielding plates for the PC boards are

mounted correctly.
After completing all work and attaching the hood, test the protective conductor according

to TI 236, document number RA0-000.12.20... (replaced by ARTD, Part 2,
ARTD-002.731.17.01)

Maintenance 1

• The picture tube parameters change with increasing time of operation. Thi s affects the

luminance and the brightness and/or the cont rast setting. For this reason, t he luminance
has to be tested every 12 months according to chapter 6-1 and, if necessary, the vide o
amplifier setting has to be perfor med according to pages 5-1 through 6-5.

• The inner part of the monitor should be cleaned with compressed air f rom time to time

depending on the amount of dust in the operating r ooms.
In order to recognize parameter devi ations, the image quality test for the specific system
must be performed every 12 months according to the IQ i nstructions.
If deviations in sharpness and geometry ar e found, correct them according to t he service
instructions.

Required documents 1

- Operating instructions for the X- ray system to which the SIMOMED monitor is
connected.

- Wiring diagrams of the corresponding SIMOMED, type X2079 or X208 0

- IQ Instructions for the X-ray system used.

- Operating Instructions for the Moni tor-Multinorm Testbox (included with the uni t)

- Operating Instructions for the Mavo- Monitor (included with the unit)

- Safety-technical Instruc tions. RA0-000.012.20... and the inst ructions
