Getting Started Teledyne API – Model T300/T300M CO Analyzer
42
Table 3-3: Rear Panel Description
Component Function
cooling fan
Pulls ambient air into chassis through side vents and exhausts through rear.
AC power
connector
Connector for three-prong cord to apply AC power to the analyzer.
CAUTION! The cord’s power specifications (specs) MUST comply with the power
specs on the analyzer’s rear panel Model number label
Model/specs label
Identifies the analyzer model number and provides voltage and frequency specs
SAMPLE
Connect a gas line from the source of sample gas here.
Calibration gases are also inlet here on units without zero/span/shutoff valve options
installed.
EXHAUST
Connect an exhaust gas line of not more than 10 meters long here that leads outside
the shelter or immediate area surrounding the instrument.
SPAN 1
On units with zero/span/shutoff valve options installed, connect a gas line to the source
of calibrated span gas here.
SPAN2/VENT
Used as a second cal gas input line when instrument is configured with zero/span
valves and a dual gas option, or as a cal gas vent line when instrument is configured
with a pressurized span option (Call factory for details).
ZERO AIR
Internal Zero Air: On units with zero/span/shutoff valve options installed but no internal
zero air scrubber attach a gas line to the source of zero air here.
RX TX
LEDs indicate receive (RX) and transmit (TX) activity on the when blinking.

during RS-232 communication. (Section 6.1).
STATUS
For ouputs to devices such as Programmable Logic Controllers (PLCs). (Section
3.3.1.5).
ANALOG OUT
For voltage or current loop outputs to a strip chart recorder and/or a data logger.
(Sections 3.3.1.3 and 3.3.1.4).
CONTROL IN
For remotely activating the zero and span calibration modes. (Section 3.3.1.6).
ALARM
Option for concentration alarms and system warnings. (Section 3.3.1.7).
