3.3 CONNECTIONS AND SETUP
This section presents connection information for setting up the instrument to operate.
3.3.1 Electrical and Pneumatic Connections
1. Refer to Figure 3-2 for the rear panel electrical and pneumatic connectors.
2. Mount the NOx scrubber with base down (arrow labeled “FLOW” pointing
down) onto the rear panel.
3. Connect tubing from NOx scrubber base fitting to rear panel fitting labeled
“FROM SCRUBBER”.
4. Connect tubing from NOx scrubber top fitting to rear panel fitting labeled
“TO SCRUBBER”.
5. Vent the EXHAUST port to atmospheric pressure and out of the room,
because of its nitric oxide content.
6. Attach the sample inlet line to the sample inlet port. The pressure of the
sample gas at the inlet port should be at ambient pressure and constant.
7. Using 1/8” stainless steel tubing, attach a cylinder with 10,000 ppm ±10%
of nitric oxide (NO) in nitrogen (N2), with an appropriate pressure
regulator, to the 1/8” stainless steel port (labeled NITRIC OXIDE) on the
rear panel as shown in Figure 3-2. Note: The NO cylinder’s pressure
regulator should be set to deliver gas at 20 PSIG ± 5 PSIG.
8. Attach a strip chart recorder and/or data-logger to the appropriate analog
output connections on the rear panel. See section on analog output
connections in the Model T200 manual for connector pin-out definitions.
9. Connect the power cord to the correct line voltage.
WARNING
Lethal voltages present inside the analyzer’s case.
Do not operate with cover off during normal operation.
Before operation, check for correct input voltage and frequency.
Do not operate without proper chassis grounding.
Do not defeat the ground wire on power plug.
Turn off analyzer power before disconnecting electrical subassemblies.
CAUTION
GENERAL SAFETY HAZARD
Analyzer Exhaust Contains Nitric Oxide Gas.
Vent pump exhaust to a well-ventilated area at atmospheric pressure.
Obtain a Material Safety Data Sheet (MSDS) for this material. Read and
rigorously follow the safety guidelines described there.
