Teledyne 9110T instruction manual Power SUPPLY/CIRCUIT Breaker

Model 9110T NOx Analyzer Principles of Operation

13.7. POWER SUPPLY/CIRCUIT BREAKER

The analyzer operates on 100 VAC, 115 VAC or 230 VAC power at either 50 Hz or 60Hz. Individual instruments are set up at the factory to accept any combination of these five attributes. A 6.75 amp circuit breaker is built into the ON/OFF switch. In case of a wiring fault or incorrect supply power, the circuit breaker will automatically turn off the analyzer.

∙Under normal operation, the 9110T draws about 1.5 A at 115 V and 2.0 A during start-up.

WARNING

ELECTRICAL SHOCK HAZARD

Should the AC power circuit breaker trip, investigate and correct the condition

causing this situation before turning the analyzer back on.

Power enters the analyzer through a standard International Electrotechnical Commission (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. AC Line power is stepped down and converted to DC power by two DC power supplies (PS).

∙One PS provides +5 VDC (3 A) and ±15 VDC (1.5/0.5 A) for logic and analog circuitry as well as the power for the O3 generator.

∙A second PS provides +12 VDC (5 A), for the PMT’s thermoelectric cooler, fans and as well as the various gas stream valves (both standard and optional).

All AC and DC Voltages are distributed via the relay PCA.
