Chapter 1: Introduction and Overview ESC Series Industrial Computer Using This Manual This manual covers installation and service of components, enclosures and cooling systems. • • • • Chapter 1 Chapter 2 Chapter 3 Appendix A Introduction and Overview Installation Maintenance and Repair Technical Support and Warranty Safety Information Caution and Warning statements are used to draw attention to vital information: Caution! If you do not follow instructions, there is a risk you may damage the equipment.
Figure 1 ESC series computer Technical Specifications Fans Dual 50 cfm (19 lps) 12 VDC, 230 mA Stainless steel ball bearings; locked rotor and polarity protected Operating temperature range: –10°C to 70°C UL Yellow Card recognized; CSA certified Environmental Temperature (Per IEC 68-2-1,2,3,14): Operating 0°C to +50°C*; Storage: -20°C to +65°C Humidity (Per IEC 68-2-1,2,3,14): Operating 10% to 95%; Storage 5% to 95% *Operation at 50°C is possible but may shorten component life.
Chapter 2: Installation Installation Requirements Mounting hardware supplied for easy installation. When determining the location for mounting, keep in mind the weight of the unit, available power connections, and access to peripheral equipment necessary for system operation. If installing a system outdoors, be certain to read the recommendations for outdoor installation provided elsewhere in this manual. ESCs require 4 Amps maximum at 120VAC, and 2 Amps maximum at 230VAC.
2) Make certain the unit mounting hardware is not compromised by the rack or cabinet installation. 3) Verify that the connection of the equipment to the supply circuit does not overload the circuit, and that a reliable earth ground is maintained for the power connection. Other mounting options, such as desk stands, are available. Outdoor Installation Although systems are dust and moisture proof, solar radiation from direct sunlight can overheat the enclosure.
1) Identify the specific location and position at which the unit is to be installed. Make sure to allow sufficient clearance for conduit and/or cable connections. Mark the mounting surface where the top edge and one side of the enclosure will be aligned. 2) The mounting points of the unit are located in a rectangular pattern 18.5” wide by 15” high. The mount points are ¾” from the sides and 1½ ” from the top and bottom of the installed enclosure.
These standard connectors are intended to be used with flexible, nonmetallic conduit or tubing. It is strongly recommended that computer installations include a flexible section of conduit, for example, three feet of conduit or two feet of tubing to allow the shock and vibration isolators a full range of motion. Caution! The conduit connectors must be sealed against adverse environments. If the unit is not connected to a closed conduit system, the connectors must be sealed with a suitable compound.
Caution! The incoming power switch must be set correctly before powering the computer. Failure to do so may cause serious damage to the equipment and or injury to personnel. 4) Connect the ground wire to the ground stud in the bottom of the enclosure as shown in Figure 2. A wire runs from this stud to the terminal block. This wire must remain connected. 5) Connect 110/220 VAC, 50/60 Hz power to the Mains Power terminal block inside the enclosure.
Chapter 3: Maintenance and Repair Very little maintenance is required. The enclosure is watertight but should be checked regularly to ensure that all components are operating properly. Contact VarTech for assistance and/or to order spare parts. Cleaning Systems are housed in stainless steel enclosures. The enclosure may be cleaned with a variety of industrial cleaners or solvents. To prevent discoloration or deterioration of the enclosure finish, avoid prolonged contact with acids or strong solvents.
