The analyzer operates on 100 VAC, 115 VAC or 230 VAC power at either 50Hz
or 60Hz. Individual units are set up at the factory to accept any combination of
these five attributes. As illustrated in Figure 7-18, power enters the analyzer
through a standard IEC 320 power receptacle located on the rear panel of the
instrument. From there it is routed through the On/Off switch located in the
lower right corner of the Front Panel. A 6.75 Amp circuit breaker is built into the
ON/OFF Switch.
AC power is distributed directly to the sample gas pump. The bench and GFC
wheel heaters as well as the GFC wheel receive AC power via the relay board.
AC Line power is converted stepped down and converted to DC power by two
DC power supplies. One supplies +12 VDC, for valves and the IR source, while
a second supply provides +5 VDC and ±15 VDC for logic and analog circuitry.
All DC voltages are distributed via the relay board.
Should the AC power circuit breaker trip, investigate and correct the
condition causing this situation before turning the analyzer back on.
