1.8 Shipping Precaution

When shipping the instrument by air, deflate the purge-air bag to prevent it from bursting due to changes in air
pressure. Deflate the bag by selecting the EMTYBAG function as described on page 13.

1.9 Functional Overview

1.9.1 General Descr iption

The Bacharach CO2 PGM-IR is a portable CO2 gas monitor designed to determine the presence and level of CO2 gas.
The monitor self-zeros using an internal zero-air (purge) bag every 4 minutes to ensure accurate gas
measurements.

During normal operation the monitor displays the type of gas being monitored (CO
current gas level and (optionally) the peak gas level detected in that area on its front panel LCD. The monitor
retains a log of previous readings that can be easily accessed at a later time for analysis.

) along with displaying both the

2

Front panel indicators and an audible alarm are provided to signal gas alarm and instrument fault conditions. The
audible alarm can temporarily be silenced by a push of a button, but will reactivate if the gas level is still above the
alarm trip point after a user defined time period has elapsed.

The unit requires only minor periodic maintenance such as the occasional replacement of filters. The monitor
incorporates active diagnostics that continuously check the system for proper operation. A front panel indicator is
provided to alert an operator of system malfunctions, and fault codes are generated that enable the operator to
identify the cause of the fault.

1.9.2 Ambient vs. Rel a tive CO2 Readings

CO2 gas is present in ambient air at a concentration of approximately 386 ppm. CO2 gas is also in the “air” that we
exhale. This should be considered when testing for CO
occupied locations.

The CO

PGM-IR has an internal purge air bag that is filled with ambient air prior to performing CO2 testing. This

2

air is used to purge the IR detector of sample gas and establish a “zero” ppm baseline. Therefore, for greatest
accuracy, it is important to:

(1) ensure the purge air bag is filled with clean ambient air (away from breathing, car exhaust, etc.), and
(2) fill the purge air bag with air that is as close as possible in temperature and RH level as the area to be

sampled for leaks.

IMPORTANT: If the purge air bag is known or suspected to be filled with “contaminated” air, use
the EMPTY BAG function to clear the bag, then fill the bag with clean air.

2.2 Connecting Gas-Sample & Exhaust Lines

2.2.1 Connecting the Gas-Sample Probe

To connect the gas-sample probe to the monitor, simply push the elbow connector into the Gas Sample Port on
the front of the monitor as shown in the illustration below.

The gas-sample line can be up to 50 ft (15.2 m) in length. All tubing bends should have a radius of no less than 5”
to ensure proper airflow. If kinks or obstructions occur in the line the monitor may not function properly.

When searching for leaks, the end of the probe should be placed near the potential leak source and positioned to
reduce the possibility of mists, aerosols, oil, water, dust, or other contaminates being drawn into the monitor.

2.2.2 Connecting the Exhaust Line (Optional)

The exhaust line carries the exhausted gas sample away from the monitor, and should be installed if the monitor is
located in a confined, poorly ventilated area.

The exhaust line can be up to 50 ft (15.2 m) in length. Ideally this line should terminate outdoors in a location that
is not exposed to the elements.

2.2.3 Using the Push-to-Connect (PTC) Fittings

Connect the exhaust line to the monitor by firmly pushing the tubing into the Exhaust Port’s push-to-connect (PTC)
fitting. See below. If the exhaust line terminates outside the building, position the tubing so that no water or
moisture can enter the line. Note that this line does not require a termination filter.

PURGE

PPM LOG function (page

PURGE indicates when the monitor is resetting its infrared detector to a

baseline of 0 ppm (relative) by using the 386 ppm (absolute) zero-air from
the internal purge bag. The purge cycle runs for approximately 10 seconds.

If the detected gas level exceeds a preset gas-alarm point, the unit will respond by turning ON the front panel
ALARM (red) light. If the AUDALRM function is activated (page 11), the audible alarm will also turn ON. Pressing
the front panel SILENCE button turns OFF the audible alarm, but the ALARM light will continue to flash as long as
the detected gas level is above the alarm point. The audible alarm will reactivate if the gas-alarm condition is not
cleared within the time period set by the SILENCE function (page 13).

If a system fault occurs (see Fault Code list on page 14), the monitor responds by turning ON the front panel FAULT
(yellow) light. If the AUDALRM function is activated (page 11), the audible alarm will also turn ON. Pressing the
front panel SILENCE button turns OFF the audible alarm, but the FAULT light will continue to flash as long as the
fault is present. The audible alarm will reactivate if the fault condition is not cleared within the time period set by
the SILENCE function (page 11). Both the FAULT light and audible alarm will automatically turn OFF after the cause
of the fault has been eliminated.

A log of the last 30 fault events can be viewed using the monitor’s FAULTS function (page 12).

2.4 Time Weighted Average (TWA) Operation

2.4.1 Overview

In addition to displaying the current gas level, the monitor can also calculate and display a Time Weighted Average
ppm value. This value is available in two formats (8 Hour or Continuous). This provides users with the most
appropriate data on their average ppm exposure in the working environment.

TWA operation is selected by using the 2ndUNIT function.

The two TWA formats are identified by the appearance of either “TWA” (for an 8-hour TWA) or ‘twa” (for a
continuous TWA) in the upper-right corner of the Data Display screen.

MEASURE 0TWA
100ppm CO2

MEASURE 0twa
100ppm CO2

Instruction 3015-9000 Rev 4 7

TWA (upper case letters) is calculated over an 8-hour period. This format is
designed to show the user
work day. After 8 hours has expired, an asterisk (*) will be displayed but the
TWA will continue to be updated.

twa (lower case letters) is continuously calculated over the operating time
of the monitor. This mode is useful for monitoring an area for a few
minutes or more and is the preferred mode of operation for checking
operating room atmospheres.

When the monitor is turned ON the following message appears if the monitor
is set up to display TWA/twa.

Press either . . .

• ENTER to start a new TWA/twa

• ESC to continue with the current TWA/twa.

Tip: If NO button is pressed within 60 seconds the monitor automatically continues with

the current TWA/twa.

NOTE: During the time the monitor is OFF, the gas measurement is assumed to be zero and will be
factored into the TWA/twa calculation.

After selecting whether to start or continue a TWA/twa, the next screen shows
the current elapsed TWA/twa time, where:

2.5 Peak Reading Operation

In addition to displaying the current CO2 level, the monitor can also be set up
to display its peak ppm measurement. The peak reading display is selected
by using the 2ndUNIT function.

The display above shows that currently the monitor is detecting 50 ppm CO2 and that a peak measurement of
70 ppm has occurred. The peak reading is reset by pressing the ENTER button.

MEASURE 00070pk
50ppm CO2

2.6 Leak Detector Operation

The monitor can be configured to operate as a Leak Detector by setting the AUDALRM function (page 11) to LEAK
DETECTOR.

When configured as a Leak Detector, the monitor will produce a leak detector type of audible feedback. At zero
ppm there will be an audible beep every 2 seconds with the beep rate increasing up to 20 beeps/second when the
ppm level reaches the ALRMLVL setting.

2.7 Standby Mode

After becoming operational, the monitor can be placed into a Standby Mode. When taken out of standby the
monitor is ready for operation without waiting an additional 5 minutes to warm up. While in standby the monitor
will stop taking gas samples and stops purging itself from the purge-air bag.

Place the monitor into its Standby Mode by pressing both the ENTER and ESC
buttons at the same time. Take the monitor out of standby by again pressing
