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.
COM 2 Serial communications port for RS-232 or RS-485. (Sections 3.3.1.9, 5.7.3, 6).
RS-232 Serial communications port for RS-232 only. (Sections 3.3.1.9, 5.7, 6.3, 6.7.2.1)
DCE DTE
Switch to select either data terminal equipment or data communication equipment
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).
ETHERNET
Connector for network or Internet remote communication, using Ethernet cable
(Section 3.3.1.9).
ANALOG IN
Option for external voltage signals from other instrumentation and for logging these
signals (Section 3.3.1.2)
USB Connector for direct connection to laptop computer, using USB cable. (Section 3.3.1.9).
