K-WANG
Xycom Automation industrial monitors meet the rigorous requirements of the plant floor with high-resolution flat panel displays in a rugged housing with an optional resistive membrane touchscreen.
The XT1502 flat panel monitor delivers crisp, bright text and graphics with a low current draw, and it fits into panels that CRTs cannot.
The XT1502 is self-contained, requiring only to be panel mounted in an appropriate enclosure and connected to 120/240 VAC and VGA source

Parts List
When you remove the XT1502 from its shipping carton, verify that you have the parts listed below.
Save the box and inner wrapping in case you need to reship the unit.
Text Conventions Used in this Manual
Throughout this manual, certain terms are formatted in ways that indicate what type of object is being described.
Some information is also segregated to draw attention quickly.
Titles, labels, and messages are indicated by italic text.
Computer filenames and text to be entered by the user will appear in a monospace font.
Operator interfaces (such as the Start menu button) and keyboard keys (such as Enter) appear in a narrow bold typeface.
Some text is segregated into Note, Caution, or Warning boxes.
Notes contain extra information that may make the nearby text, especially the text just before the note, more understandable.
Cautions contain information necessary to prevent damage to the hardware.
Warnings contain information necessary to safeguard the operator.
System Power
It is a good practice to use isolation transformers on the incoming AC power line to the system.
An isolation transformer is especially desirable in cases in which heavy equipment is likely to introduce noise onto the AC line.
The isolation transformer can also serve as a step-down transformer to reduce the incoming line voltage to a desired level.
The transformer should have a sufficient power rating (units of volt-amperes) to supply the load adequately.
The code specifies that a grounding path must be permanent (no solder), continuous, and able to safely conduct the ground-fault current in the system with minimal impedance (minimum wire required is 18 AWG, 1 mm).
Observe the following practices:
• Separate the power and ground (P. E., or Protective Earth) cable from signal cables at the point of entry to the enclosure.
To minimize the ground wire length within the enclosure, locate the ground reference point near the point of entry for the plant power supply.
• All electrical racks or chassis and machine elements should be Earth Grounded in installations where high levels of electrical noise can be expected.
The rack/chassis should be grounded with a ground rod or attached to a nearby Earth structure such as a steel support beam.
Connect each different apparatus to a single Earth Ground point in a "star" configuration with low impedance cable.
Scrape away paint and other nonconductive material from the area where a chassis makes contact with the enclosure.
In addition to the ground connection made through the mounting bolt or stud, use a one-inch metal braid or size #8 AWG wire to connect between each
Excessive Heat
To keep the temperature in range, the cooling air at the base of the system must not exceed the maximum temperature specification (see pg. 1-4).
Allocate proper spacing between internal components installed in the enclosure.
• Place any fans or blowers close to the heat-generating devices.
If using a fan, make sure that outside air is not brought inside the enclosure unless a fabric or other reliable filter is used.
This filtration prevents conductive particles or other harmful contaminants from entering the enclosure.
• Do not place incoming power line devices (such as isolation or constant voltage transformers, local power disconnects, and surge suppressers) near the system.
The proper location of incoming line devices keeps power wire runs as short as possible and minimizes electrical noise transmitted to the unit.
• Avoid overloading the supply circuit
Back Light Replacement Procedure
After 50,000 hours of use, the two lamps used for LCD back lighting may become dim or burn out. You may return the monitor to Xycom for lamp replacement or you can order new lamps and follow the procedure below to install them.
You can perform the lamp replacement procedure without removing the monitor from the NEMA enclosure where it is mounted, but you should do this only in a clean environment.
Otherwise, the procedure is better performed at a service bench.
6. Look in the hole where the lamp is presently installed and note the small black locking tab on the front side of each hole. With a small slotted screwdriver, depress the tab while carefully pulling on the wires and slide the lamps outward.
Discard the old lamps.4-1 VGA Input Connector Pin Out
