Section 1 INTRODUCTION About LCD Monitors 1.1 What you gain by using an LCD monitor in your industrial controls LCDs are the future of display technology. CRTs although they have dropped in cost significantly, do not offer the performance, reliability, and mounting options available with LCDs. LCD monitors consist primarily of an LCD, Video Board and a Back Light video. The LCD determines to a large extent the viewing angle, brightness and contrast.
1.2 Product Safety Precautions ⇒ Ensure that sufficient space is available around the display to provide the circulation necessary for cooling. ⇒ Ensure that the ambient air temperature will not exceed the specified maximum temperature. ⇒ Do not attempt to service this display yourself. The rear chassis has a seal so that non qualified personal will not expose themselves to dangerous voltages or other risks.
Section DISPLAY SETUP 2 2.1 INSTALLATION Do not allow anything to rest upon or roll over the power cord, and do not place the display where the power cord is subject to damage. Do not use this display near water such as near a sink, in a wet location where there is standing water. Displays are provided with ventilation openings in the cabinet to allow the release of heat generated during operation. If these openings are blocked, built-up heat can cause failures which may result in a fire hazard.
2.3 Signal Connections Cont. The power and signal inputs to the monitor are located on the rear of the unit.
Section GETTING STARTED 3 3.1 OPERATING INSTRUCTIONS The monitor must be connected to a suitable DC power source and video signal. The monitor will switch on as soon as the power is applied and a picture will be displayed. Basic User Controls Adjustments to the picture can be made by means of the push button controls on the front of the monitor. The → & ← buttons control the contrast of the display.
3.2 PROCEDURE FOR PICTURE ADJUSTMENT Each value that is adjusted is automatically saved when the highlighted line is moved, the only exception is when the RESTORE function is used. If at any time the monitor cannot accept the new settings it will recall the previous good values. Step 1 Move picture so the top left hand corner is positioned correctly. The top left hand of the picture needs to be 2 to 3mm from the corner of the screen. Use the ↑ & ↓ buttons untill HORIZONTAL POS is highlighted.
3.3 OTHER OSD FUNCTIONS Restore Use this function if adjustments mad to monitor need to be undone. This returns the monitor to the state when the OSD was STARTED. Use the ↑ & ↓ buttons until RESTORE is highlighted. Then use the → & ← buttons to undo adjustments made to the monitor. Reset Mode(s) This has four options that are selectable as detailed below. Use the ↑ & ↓ buttons until RESET MODE(S) is highlighted. Then use the → or ← buttons to swithch between NO-YES - ALL - NEW.
3.5 Frequency & Frequency Fine Adjustment of TFT monitors The Video signal is made up of pixels. These are generated in the video generator (process controller, PC, etc.) A crystal oscillator controls the rate at which the pixels are generated: this is called the Dot Clock. When the TFT monitor receives the video signal it must convert it back to it’s individual pixels in digital form. To do this it must sample the video at the same rate as the dot clock.
3.6 SIGNAL FORMATS These signals are currently factory programmed into the monitor Resolution V Rate H Rate Syncs H V Application 640 x 350 70Hz 31.475kHz VGA 640 x 400 70Hz 31.475kHz VGA 640 x 480 60Hz 31.475kHz VGA 1024 x 384 40Hz 16.67kHz IECC Railway Signaling 1024 x 768 60Hz 48.40kHz XGA 1280 x 1024 60Hz 63.98kHz SXGA 640 x 384 50Hz 20.65kHz ABB Mod300 640 x 384 60Hz 24.78kHz ABB Mod300 800 x 600 56Hz 35.21kHz SVGA 604 x 240 60Hz 15.
Section 4 TROUBLESHOOTING GUIDE TROUBLESHOOTING GUIDE Trouble Troubleshooting Tip Unable to set Vertical Size The Vertical Size value is limited by what values are set for Frequency and Horizontal size. Not all video modes can be shown full screen. Sometimes the vertical size will have to be small. Cannot Set Correct Frequency On some systems there are no pictures available that make frequency setting easy. This can make it very hard to see what is happening on the screen.
Section 5 CLEANING AND MAINTANENCE Cleaning Occasionally clean the display panel and cabinet with a soft cloth dampened (not soaked) with a mild (non-abrasive) glass cleaner. Keep turning a fresh side of the cloth toward the screen surface to avoid scratching it with accumulated grit. Note: The solvent should be applied only to the cloth, and not directly on the monitor screen. Do not use paper products as they may scratch the surface. To minimize the risk of abrasion, allow the screen to stand dry.
