Teledyne 9110T Pneumatic Connections, Testing it before setting up the rest of the chain

Model 9110TH NOx Analyzer Getting Started

Note	TAI recommends setting up the first link, between the Host and the first analyzer,
	and testing it before setting up the rest of the chain.

RS-485 CONNECTION

As delivered from the factory, COM2 is configured for RS-232 communications. This port can be reconfigured for operation as a non-isolated, half-duplex RS-485 port. Using COM2 for RS-485 communication will disable the USB port. To reconfigure this port for RS-485 communication, please contact the factory.

3.3.2. PNEUMATIC CONNECTIONS

This section provides not only pneumatic connection information, but also important information about the gases required for accurate calibration (Section 3.3.2.1); it also illustrates the pneumatic layouts for the analyzer in its basic configuration and with options.

Before making the pneumatic connections, carefully note the following cautionary and additional messages:

IMPORTANT

CAUTION

GENERAL SAFETY HAZARD

Do not vent calibration gas or sample gas into enclosed areas.

CAUTION – GENERAL SAFETY HAZARD

In units with a permeation tube option installed, vacuum pump must be connected and powered on to maintain constant gas flow though the analyzer at all times. Insufficient gas flow allows gas to build up to levels that will contaminate the instrument or present a safety hazard to personnel.

Remove permeation tube when taking analyzer out of operation, and store in sealed container (use original container that tube was shipped in).

(See Figure 3-6 for location and Section 11.3.6 for instructions on how to remove the perm tube when the unit is not in operation).

IMPACT ON READINGS OR DATA

Sample and calibration gases should only come into contact with PTFE tubing.
