Pneumatic Sensor Board; Power Supply/Circuit Breaker - Teledyne T200 User Manual

PNEUMATIC SENSOR BOARD

The flow and pressure sensors of the analyzer are located on a printed circuit assembly just
behind the PMT sensor. The signals of this board are supplied to the motherboard for
further signal processing. All sensors are linearized in the firmware and can be span
calibrated from the front panel.

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 analyzer draws about 1.5 A at 115 V and 2.0 A during
•
start-up.
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 O
The 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, except for the dedicated 24 VDC, are distributed via the relay
PCA.

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.
