Controls & Instrumentation:Vertical, free-standing, front access, NEMA-1 cubicle; mode selector switch and keylocking override switches for sequence controlled, semi-automatic pumping system. Vacuum monitors include one thermocouple gauge, (1 to 1000 microns range), and one two-station thermocouple gauge (1 to 100 microns range) for chamber or foreline pressures plus one ionization (hot filatment) gauge for chamger submicron range. Components are interlocked to avoid undesirable operating conditions (such as oil migration in the pumping system and inadequate cooling water), to avoid electrical hazards for operting personnel and to prevent loss of vacuum. (Download technical bulletin for full details.)Vertical, free-standing, frong access, NEMA-1 cubicle, contains self-sequncing pumping system control with graphic panel. Pilot lamps indicate pump opertion and condition of valves. Vacuum thermocuople gauges (1-1000 microns) monitor pressure in melt chamber, mold lock, and booster pump foreline. Induction power supply controls and output instruments. Components are interlocked to prvent operating conditins which might damage them (such as oil migration in the pumping system and inadequate cooling water), to avoid electrical hazards for operating personnel and to prvent loss of vacuum. (Download technical bulletin for full details.)
