General information

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 with a functioning Memoskop. If this is not available, the test pattern of the Multinorm test box (refer to "Measuring instruments and auxiliary devices"), the corresponding digital system, or the Videomed D can be used, if necessary.

•Except for the luminance, adjustments are required only after replacing a module or picture tube.

•The maximum luminance influences the image quality to a considerable extent. If after a lengthy operating time, the luminance does not attain a maximum of > 300 cd/m2, replace the picture tube.

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

Service

Repairs are limited to replacing modules.

Individual parts for PC boards are not available.

Parts available for delivery are shown in the spare parts list.

•Test templates are included in the appendix. Their purpose is to simplify service. The test template is fastened onto the picture tube to adjust the image geometry. If the image geometry is correctly adjusted, the intersections of the grid lines must be located within the rings. Otherwise, adjust the image geometry in accordance with Chap. 4.

Safety information

Re: DHHS requirements

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

-Do not replace components or make circuit modifications on the PC boards. Always replace PC boards when servicing the system.

-After replacing the power pack board SV1, check the voltage U = 48 V ± 0.5 V at 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 insulation for
		primary/secondary (4 kV).
•	Interference	acc. to VDE 0871, Part 2, limit value B,
	suppression:	acc. to VDE 0871, Part 3, interference suppression grade N,

•Comply with the safety-technical information in TI 236 “Safety regulations for installation and maintenance.”

•Check that the monitor mounting and hardware are secure and show no signs of damage.

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

Observe the safety instructions according 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

•The picture tube parameters change with increasing time of operation. This affects the luminance and the brightness and/or the contrast setting. For this reason, the luminance has to be tested every 12 months according to chapter 6-1 and, if necessary, the video amplifier setting has to be performed according to pages 5-1 through 6-5.

•The inner part of the monitor should be cleaned with compressed air from time to time depending on the amount of dust in the operating rooms.

In order to recognize parameter deviations, the image quality test for the specific system must be performed every 12 months according to the IQ instructions.

If deviations in sharpness and geometry are found, correct them according to the service instructions.

Required documents

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

-Wiring diagrams of the corresponding SIMOMED, type X2079 or X2080

-IQ Instructions for the X-ray system used.

-Operating Instructions for the Monitor-Multinorm Testbox (included with the unit)

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

-Safety-technical Instructions. RA0-000.012.20... and the instructions “Handling of vacuum container” TI 201 from TI-folder part 2, replaced by ARTD, Part 2, ARTD-002.731.12.01.
