Case

The EAGLE 2’s sturdy, high-impact plastic case is radio frequency (RF) resistant and is suitable for use in many environmental conditi ons, indoors and out. The case is dust proof and water resistant. It’s two main components, the top case and bottom case, are held together with three screws located on the bottom case. The interface between the top case and bottom case is gasketed. A sturdy, well balanced handle on the top case allows you to hold the instrument comfortably. A cle ar plastic window is locat ed on the top case to the front of the handle for viewing the LCD.

A removable battery case is located at the rear of the bottom case. A thumbscrew secures the battery case to the bottom case. The interface between the battery case and the bottom case is gasketed. Six raised feet on the bottom of the case, four on the bottom case and two on the battery compartment, raise the EAGLE 2 slightly from the surface on which it rests.

Sensors

The EAGLE 2 uses up to six sensors to monitor combustible gas, oxygen

), carbon monoxide (CO), hydrogen sulfide (H2S), and various other toxic

gases simultaneously. The sensors are located inside the EAGLE 2 bottom case and are installed in the flow chamber. The sensors described below are the four standard sensors. See “Appendix D: PID Sensors” for a description of the PID sensors, “Appendix E: ESM-01 Toxic Sensors” for a description of the ESM-01 toxic sensors, “Appendix F: TC Sensors” for a description of the TC sensors, “Appendix G: Infrared Carbon Dioxide Sensors” for a description of the IR CO

for a description of the IR methane sensors, and “Appendix I: Infrared Hydrocarbon Sensor” for a description of the IR hydrocarbon sensor. The standard sensors use different detection principles as described below.

sensors, “Appendix H: Infrared Methane Sensor”

Catalytic Combustible Gas Sensor (LEL Sensor)

The catalytic combustible gas (LEL) sensor detects combustible gas in the %LEL range. It uses a catalytic element for detection. The reaction of gas with oxygen on the catalyst causes a change in the resistance of the element which changes the current flowing through it. The current is amplified by the EAGLE 2’s circuitry, converted to a measurement of combustible gas concentration, and displayed on the LCD.

The LEL sensor housing includes a sintered metal flame arrestor on one end that allows gas to diffuse into the sensor. On the other end, five pins extend from the sensor. The sensor cable connects to these pins on one end and terminates in a four-position connector on the other end which plugs into the HC socket on the main PCB (see “Main PCB” on page 12).

8 • I n s t r u m e n t D e s cri p t i o n EAGLE 2 Operator’s Manual

Oxygen Sensor

The O2 sensor is a galvanic type of sensor. A membrane behind the openings on the sensor face allows gas to diffuse into the sensor at a rate proportional

to the partial pressure of oxygen. The oxygen reacts in the sensor and produces a voltage proportional to the concentration of oxygen. The voltage is measured by the EAGLE 2’s circuitry, converted to a measurement of gas concentration, and displayed on the LCD.

The sensor includes a short cable that terminates in a round 7-position connector . It m ates wit h the OXY pins on the main PCB (see “Main PCB” on page 12).

CO and H2S Sensors

The CO and H2S sensors are electrochemical sensors that consist of three precious metal electrodes in a dilute acid electrolyte. A gas permeable

membrane covers the sensor face and allows gas to diffuse into the electrolyte. The gas reacts in the sensor and produces a current proportional to the concentration of the target gas. The current is amplified by the EAGLE 2’ s circuitry, converted to a measurement of gas concentration, and displayed on the LCD.

The CO and H

S sensors are physically very similar. Except for their

markings and wire colors, they look almost identical. A three-position connector at the end of a 2-wire cable from each sensor plugs into a socket on the main PCB. The sockets on the main PCB for the CO and H

S sensors a r e

labeled CO and H2S. Normally, the CO connector plugs into the CO socket and the H2S plugs into the H2S socket. However, because of the way that the main PCB circuitry is arranged, if the CO sensor is plugged into the H2S socket and the H2S sensor is plugged into the CO socket, the sensors will still operate properly and the CO and H2S readings will still appear on the channels that are programmed for those gases.

LCD

A digital LCD (liquid crystal display) is visible through a clear plastic window in the top case. The LCD simultaneously shows the gas reading for all installed sensors. The LCD also shows information for each of the EAGLE 2’s operating modes.

Battery Case & Batteries

Four C-size alkaline batteries (standard) or optional rechargeable C-size Ni-MH batteries power the EAGLE 2. They are ins talled in the battery case which is located at the rear of the bottom case. The battery case is secured to the bottom case with a thumbscrew.

Instrument run time is dependent upon battery type. At 25°C, alkaline batteries power the EAGLE 2 for 16 hours of non-alarm operation. Ni-MH batteries will power the EAGLE 2 for 18 hours of non-alarm operation. The current battery voltage is viewable in Display Mode (see “Display Mode” on page 40).

When the EAGLE 2 detects low battery voltage, a low battery warning is activated. When battery voltage is too low for operation, the EAGLE 2 sounds a dead battery alarm.

The alkaline or Ni-MH batteries can be accessed for replacement by unscrewing the thumbscrew that secures the battery case to the bottom case and pulling the battery case away from t he bottom case. The Ni-MH bat teries can be recharged by using the EAGLE 2 charger (see “Replacing or Recharging the Batteries” on page 72).

NOTE: Use of batteries or battery chargers not specified by RKI

Instruments, Inc. will void the CSA classification and may void the warranty.

WARNING: To prevent ignition of a hazardous atmosphere, batteries

must only be changed or charged in an area known to be nonhazardous.

EAGLE 2 Operator’s Manual Instrument Description • 13

Flow System

The EAGLE 2 flow system consists of the inlet fitting, hydrophobic filter, pump, internal tubing, differential pressure (DP) switch, sensor chamber, charcoal filter, and exhaust fitting.

Inlet Fitting

The inlet fitting is on the right front (when viewed from the front) of the bottom case. It is a nickel plated brass quick connect fitting. It mates with either the sample hose or with the hydrophobic probe.

Hydrophobic Filter

The hydrophobic filter is located in the bottom case above the sensors. Normally the hydrophobic probe accessory (see “Hose and Probe” on page 15) will prevent water and particulate contamination from entering the flow system, but if the probe is not used, the hydrophobic filter will stop water and particulates from penetrating further into the flow system. If it becomes dirty or water logged, replace it (see “Replacing the Hydrophobic Filter” on page 77).

Pump

A diaphragm pump ins ide the rear of the bot tom case draws the sample to the sensors. It can draw sample from as far as 125 feet from the EAGLE 2.

CAUTION: Sample hose lengths of more than 125 feet are not r ecommended

for the EAGLE 2 because of flow rate reduction and increased response time. Consult RKI Instruments, Inc. for sample hose lengths longer than 125 feet.

Internal Tubing

The flow system includes polyurethane tubing to route the sample between the various components of the flow system. The internal sample tubing is not user serviceable.

Differential Pressure (DP) Switch The DP switch is inside the front of the bottom case. It senses the EAGLE 2’ s

flowrate by monitoring the pressure drop between points in the flow system. When the flowrate becomes too low for safe operation of the EAGLE 2, a set of contacts inside it open and the EAGLE 2 indicates a low flow alarm.

Sensor Chamber

A PVC block in the bottom case is configured to accept the four gas sensors. It routes the sample to each sensor. The LEL sensor and the oxygen sensor are retained in the sensor chamber by brackets. The CO and H

S sensors are

each pushed past two sealing O-rings into the chamber and are retained by

14 • I n s t r u m e n t D e scr i p t i o n EAGLE 2 Operator’s Manual

the O-ring compression force.

Charcoal Filter

The charcoal filter is located in the front of the flow chamber next to the CO sensor . It contains activated charcoal. The CO sensor will respond if exposed to H

S and certain hydrocarbon gases. The charcoal filter scrubs these gases

out of the sample to avoid fal se CO readings. If false or elevated CO readings are noticed, especially in the pres ence of H

charcoal inside the filter cannot be replaced; the entire filter must be replaced.

Exhaust Fitting

The exhaust fitting is located below the inlet fitting. It routes the gas sample out of the EAGLE 2. It includes a female 10-32 thread that can be used for the installation of a hose barb or other type of fitting that has a male 10-32 thread so that the exhaust can be routed to a particular location with flexible tubing if desired.

Standard Accessories

S, change the charcoal filter. The

Standard accessories include the shoulder strap, the sample hose, and the hydrophobic probe.

Shoulder Strap

A comfortable elastic shoulder strap clips to the EAGLE 2 at the front and rear of the top c ase. It clips to s tainless steel ri ngs that a re install ed in feat ures on the top case. It can be removed from the EAGLE 2 by opening the clip at each end of the strap and removing it from the strap ring at the front and rear of the top case.

Hose and Probe

A 5 foot polyurethane sample hose and a 10 inch hydrophobic probe are included as standard. The hose has a male quick connect fitting on one end and a female quick connect fitting on the other end. The probe has a male quick connect fitting. Normally, the male end of sample hose is installed in the EAGLE 2 inlet fitting and the probe is installed in the female end of the hose. However, if the sample hose is not needed for monitoring a particular area, the probe may be installed directly to the inlet fitting. Sample hose lengths are available from 5 feet (standard length) to 125 feet (see “General Parts List” on page 84). A teflon lined hose is provided with all units that contain a PID sensor. This hose must be used when operating a PID EAGLE 2 (see “Appendix D: PID Sensors” on page 136).

EAGLE 2 Operator’s Manual Standard Accessories • 15

CAUTION: Sample hose lengths of more than 125 feet are not r ecommended

for the EAGLE 2 because of flow rate reduction and increased response time. Consult RKI Instruments, Inc. for hose lengths longer than 125 feet.

The probe includes a replaceable particle filter and hydrophobic filter disk that prevent particulates and water from entering the EAGLE 2’s flow system. See “Replacing the Hydrophobic Probe’s Particle Filter and Hydrophobic Filter Disk” on page 75 for instructions to replace the particle filter and hydrophobic filter disk.

NOTE: When using the probe with a PID EAGLE 2, be sure that th e particle

filter is not installed.

Rechargeable Ni-MH Batteries

Rechargeable Ni-MH batteries are available for the EAGLE 2. A fully charged set of Ni-MH batteries will power the EAGLE 2 for 18 hours. The batteries will last for a minimum of 500 charge cycles. See “General Parts List” on page 84 for ordering information.

Battery Chargers

Three battery chargers are available for the EAGLE 2 to charge the optional Ni-MH batteries, the standard AC charger, a DC charger with a vehicle plug adapter, and an AC/DC charger with a vehicle plug adapter.

AC Charger

The standard AC charger consists of the charging module, which includes all of the charging circuitry, and an AC adapter. The char ging modul e include s a five foot cable with a connector on the end that mates with the EAGLE 2 charging socket. The AC adapter plugs into a 115 VAC wall outlet and connects to the charging module with a jack on the end of a five foot DC output cable. The AC adapter will also work for 100 VAC or 220 VAC if an appropriate plug adapter is provided. The AC charging station is shown below in Figure 7.

Optional Probes

Various optional probes designed for specific applications are available for the EAGLE 2. They include the following:

• 30 inch aluminum probe

Figure 9: 30 Inch Aluminum Probe

This probe is designed for applications where it is necessary to put the probe tip in areas that are out of reach with the standard probe. A small breather hole near the end of the probe tube prevents interruption of sampling and a low flow alarm if the probe tip is blocked.

18 • O p t i o n a l A c c e s s or i e s EAGLE 2 Operator’s Manual

• 30 inch stainless steel probe

Figure 10: 30 Inch Stainless Steel Probe

This probe is physically the same as the 30 inch aluminum probe and is intended for applications where a high level of corrosion resistance is required in the long probe tube.

• 4 foot stainless steel probe

Figure 11: 4 Foot Stainless Steel Probe

This probe is designed for areas where it is necessary to put the probe tip in areas that are out of reach for even the 30 inch probes. A stainless steel probe tube is used because the length of the probe tube requires a high degree of rigidity. Stainless steel is more rigid than other normally used materials. A small breather hole near the end of the probe tube prevents interruption of sampling and a low flow alarm if the probe tip is blocked.

• Barhole probe

Figure 12: Barhole Probe

This probe is designed specifically for barhole testing. See “Appendix K: Using the EAGLE 2 in Bar Hole Mode” for an in-depth discussion of using the EAGLE 2 in Bar Hole Mode.

• 10 inch probe with dust filter

Figure 13: 10 Inch Probe With Dust Filter

This probe is designed for use where drawing water or moisture into the EAGLE 2 is not a concern. Instead of a hydrophobic filter, a cotton dust filter is used.

• 32 inch telescoping probe with dust filter

This probe is designed for use where it is necessary to put the probe tip in areas not accessible with the 10 inch probe with dust filter and applications where the probe tube must be collapsible for storage.

• 7 foot telescoping probe with dust filter

This probe is designed for use where it is necessary to put the probe tip in areas not accessible with the 32 inch te lescoping probe with dust filter and applications where the probe tube must be collapsible for storage.

External Dilution Fittings

Two external dilution fittings are available for the EAGLE 2, a 1:1 dilution fitting and a 3:1 dilution fitting. They are designed to mate with the inlet fitting and accept a sample hose or probe. The fittings are made with brass and nickel plated brass and are appropriate for use with the four standard gases. The 1:1 fitting is normally used when it is necessary to introduce air into a sample that has no oxygen or a very low level of oxygen, such as a nitrogen purged sample. Both the 1:1 and 3:1 fittings can also be used when one of the target gas levels in the sample area will likely be present in a concentration above the detection range for that gas. Since the fittings partially consist of unplated brass, they are not appropriate for detection of elevated levels of H

S or of gases that are eas ily absorbed such as Cl2 or SO2.

Using the Battery Charger for Continuous Operation

The battery charger can be used with an AC adapter or a vehicle plug DC adapter to run the EAGLE 2 in continuous operation instead of charging the batteries. Batteries do not need to be installed in the EAGLE 2 but if there are batteries installed, they must be NiMH batteries and they must have a charge.

WARNING: Use the EAGLE 2 charger’s continuous operation mode to

power the EAGLE 2 only if NiMH batteries are installed in the EAGLE 2 or if no batteries are installed in the EAGLE 2. Do not use the charger for continuous operation if alkaline batteries are installed.

1. Place the EAGLE 2 in the area to be monitored.

2. Plug the power adapter into either an AC outlet or into a vehicle outlet depending on which charger is being used.

3. Set the switch on the module to “CONT. OPERAT.”.

4. Make sure the EAGLE 2 is off.

5. Make sure the adapter and module are connected.

6. Make sure that the NiMH batteries are either charged or removed.

NOTE: If the batteries are not charged, the EAGLE 2 will not turn on and

will instead give a “Charge Ba tteri es” indi cati on when it is powered up after Step 7 below.

2. Take the EAGLE 2 to the monitoring area. Put the probe tip in the area to be monitored.

NOTE: If you notice that water has entered the flow system through the

probe, replace the probe’s hydrophobic filter and inspect the O-ring for filter particles. See “Replaci ng the Hydrophobic Probe’s Particle Filter and Hydrophobic Filter Disk” on page 75 for instructions to replace the hydrophobic filter.

3. Wait 10 - 15 seconds and observe the display for gas readings. If a reading is observed, allow the reading to stabilize to determine the gas concentrations present.

NOTE: Response time increases with the length of the sample hose. Long

sample hoses will require more time to show a response at the EAGLE 2. The maximum samp le h ose l en gth recomme nd ed for th e EAGLE 2 is 125 feet. Consult RKI Instruments, Inc. for longer sample hose lengths.

4. If a gas alarm occurs, take appropriate action. See “Responding to Alarms” on page 38.

Using Optional Sample Hoses

The standard sample hose for the EAGLE 2 is 5 feet long. Optional hoses are available up to 125 feet long. If you are considering using a longer hose, keep in mind that a longer hose will increase the EAGLE 2’ s res ponse time and the flowrate may decrease close to the low flow alarm point.

CAUTION: Sample hose lengths of more than 125 feet are not r ecommended

for the EAGLE 2 because of flow rate reduction and increased response time. Consult RKI Instruments, Inc. for hose lengths longer than 125 feet.

Using Exhaust Tubing

The EAGLE 2’s exhaust fitting has a female 10-32 thread to allow for the installation of a hose barb fitting with a 10-32 thread to which a flexible exhaust tube can be connected. If you utilize this feature, the tubing used must have a minimum internal diameter of 1/8 inch. RKI Instruments, Inc. recommends using flexible polyurethane tubing with a maximum exhaust tube length of 20 feet. Consult RKI Instruments, Inc. for exhaust tubing lengths longer than 20 feet.

Combustible Gas Detection

There are three issues to keep in mind when monitoring for combustible gas.

• The catalytic combustible sensor will respond to any combustible gas.

The standard calibration gas for the EAGLE 2 catalytic combustible channel is methane (CH

combustible gas, such as hexane or propane, the gas name for the catalytic combustible channel will reflect the target gas.

The table below lists the conversion factors for several hydrocarbon gases if the EAGLE 2 is calibrated to methane . To use this table, multiply the display reading on the combustible gas channel by the factor in the appropriate row to obtain the actual gas concentration. For example, i f you are detecting pentane and the display reads 10% LEL for the catalytic combustible channel, you actually have 10% LEL x 1.38 = 13.8% LEL pentane present.

* Vapor pressure too low for significant LEL reading

• The EAGLE 2 provides the catalytic combustible sensor with some

protection against exposure to high levels of combustible gas which can damage the sensor. It does this by turning off the combustible sensor power temporarily when it determines that an over scale (more than 100% LEL) concentration of combustible gas is present that may damage the sensor. Nevertheless, concentrations of combustible gas of more than 100% LEL can still affect the zero level or calibration of the combustible sensor if the concentration is high enough.

CAUTION: Do not expose the catalytic combustible sensor to high

concentrations of combustible gas such as that from a butane lighter. Exposur e to high concentrations of combustible gas may adversely affect the performance of the sensor.

32 • M e a s u r i n g M o d e , No r m a l O p e r a t i on EAGLE 2 Operator’s Manual

CAUTION: Any rapid increase in the combustible gas reading on the

catalytic combustible channel followed by a declining or erratic reading may indicate a gas concentration above the LEL which may be hazardous.

• Some gases such as silicone vapors, chlorinated hydrocarbons, and

sulphur compounds can contaminate the detection elements inside the combustible sensor damaging the sensor and result in reduced response to combustible gas. Make every effort to avoid these gases. The catalytic combustible sensor has an integral H

S scrubber for protection from H2S

exposure resulting from normal use, but you should avoid exposure to high levels of H

S and other sulphur compounds.

Monitoring Combustible Gas in the PPM or %Volume Range

The standard factory configuration for the EAGLE 2 allows the user to use the RANGE ▼ SHIFT button to change the displayed detection units of the catalytic combustible channel between %LEL, ppm, and %volume. It is possible to disable this capability and set the EAGLE 2 to display only one of the detection units by using the Catalytic Units menu item in Setup Mode. See “Setting the Catalytic Det ection Units” on page 113 for instructions to s et this Setup Mode Menu item.

The detection range of the combustible catalytic channel when set for ppm or %volume will correspond to 0 - 100% LEL for the configured gas. For example, the LEL for methane (CH

) is 5% volume, or 50,000 ppm. So if the

catalytic combustible channel is displayed in terms of %volume, the full scale is 5.00% and if it is displayed in terms of ppm, the full scale is 50,000 ppm.

There are special considerations that must be taken into account when monitoring combustible gas in the ppm range with the catalytic combustible channel. Because of the high sensitivity in the lower part of the ppm range, the catalytic combustible channel needs more time than the warm-up period to stabilize after the EAGLE 2 is turned on if it is going to be used for ppm level detection. The reading increments in the ppm range are smallest in the lower part of the range and increase as the reading increases as follows:

• 5 ppm increments from 0 ppm to 200 ppm

• 10 ppm increments from 200 ppm to 1,000 ppm

• 50 ppm increments from 1,000 ppm to 10,000 ppm

• 250 ppm increments from 10,000 ppm to 50,000 ppm

If the catalytic combustible channel is configured for the user defined gas in Setup Mode (see “Configuring the Combustible Gas” on page 108), the ppm ratio defined for the gas must be considered. For example, if the ppm ratio is set higher than 50,000 ppm, then when the display units are set as ppm, the reading will not go above 50,000 ppm which is equivalent to 33 % LEL and 5 %volume. So if the gas reading is higher than 50,000 ppm, the ppm unit reading will indicate 50,000 ppm and also indicate an overscale condition.

34 • M e a s u r i n g M o d e , No r m a l O p e r a t i on EAGLE 2 Operator’s Manual

The %LEL and %volume unit readings will still increase up to 100% LEL and 15 %volume respectively, which are equivalent to 150,000 ppm.

The catalytic combustible sensor is slightly affected by humidity. This is not apparent when the EAGLE 2 is used for %LEL or %volume detection, but because of the high sensitivity in the ppm range, significant humidity changes can affect the ppm readin g, es pecia ll y in the lower part of the range . Take care to allow the unit to acclimate to a new environment for about a minute and perform a demand zero in a fresh air location when you move between areas of different humidity.

CAUTION: If the catalytic combustible channel is being calibrated with a

gas concentration of 1000 ppm or lower, the a 24 inch humidifier must be used for accurate calibration. See “Chapter 4: Calibration Mode” on page 55 for more explanation and instructions for calibration.

To monitor for combustible gas in the ppm range:

1. Start up the EAGLE 2 as described in “Start Up” on page 22.

2. Allow the EAGLE 2 to run for 3 - 5 minutes after the startup sequence is complete and it is in Measuring Mode. This allows the catalytic combustible sensor to stabilize sufficiently for ppm monitoring.

NOTE: This extra stabilization period is not necessary if monitoring in the

%LEL or %volume range.

3. Set the catalytic combustible channel’s units to be ppm by using the RANGE ▼ SHIFT button.

4. Perform a demand zero as described in “Performing a Demand Zero” on page 27.

5. Proceed to monitor for gas as described in “Monitoring an Area” on page 30.

Measuring Mode, Alarms

This section covers alarm indications in Measuring Mode. It also describes how to reset the EAGLE 2 after an alarm has occurred and how to respond to an alarm condition.

NOTE: False alarms may be caused by radio frequency (RF) or

electromagnetic (EMI) interference. Keep the EAGLE 2 away from RF and EMI sources such as radio transmitters or large motors.

EAGLE 2 Operator’s Manual Measuring Mode, Alarms • 35

Alarm Indications

The EAGLE 2 will sound an alarm and flash the LED arrays when one of the target gas concentrations rises above the Low Alarm level, or in the case of oxygen falls below the Low Alarm level, for that gas.

The EAGLE 2 also sounds an alarm and flashes the LED arrays when one of the target gas concentrations rises above the High Alarm level and when the STEL and TWA alarm levels are reached for CO and H

NOTE: If an alarm condition occurs while you are in Display Mode, the

EAGLE 2 will automatically bring up the alarm screen instead.

When a failure condition occurs, such as a sensor failure, low flow, or dead battery condition, the unit will also sound an alarm and flash the LED arrays.

The table below summarizes the types of alarms produced by the EAGLE 2 and their indications.

WARNING: An over range condition may indicate an extreme

combustible gas, toxic gas, or oxygen concentration . Confirm a normal condition with a different EAGLE 2 or with another gas detecting device.

1. Determine which channel is in alarm.

2. Follow your established procedure for an extreme gas condition.

3. Reset the alarm using the POWER ENTER RESET button once the alarm

condition has cleared.

4. Calibrate the EAGLE 2 as described in “Chapter 4: Calibration Mode” on

page 55.

5. If the over range condition continues or if you are not able to successfully

calibrate the unit, you may need to replace the sensor that has triggered the over range alarm.

6. If the over range condition continues after you have replaced the sensor,

contact RKI Instruments, Inc. for further instructions.

Responding to Battery Alarms

WARNING: The EAGLE 2 is not operational as a gas monitoring device

during a dead battery alarm. Take the Model EAGLE 2 to a non-hazardous area and replace or recharge the batteries as described in “Replacing or Recharging the Batteries” on page 72.

The EAGLE 2 is fully functional during a low battery warning. However, only a limited amount of operating time remains, approximately 1 - 2 hours. The amount of time depends on how often the LCD backlight is used and how often the unit is responding to alarm conditions. Recharge the Ni-MH batteries or replace the alkaline batteries as soon as possible as described in “Replacing or Recharging the Batteries” on page 72.

NOTE: Alarms and the LCD back light consume battery power and reduce

the amount of operating time remaining.

Responding to Sensor Failure Alarms

1. Determine which sensor has triggered the sensor failure alarm.

2. Try calibrating the sensor first, as described in “Chapter 4: Calibration

Mode” on page 55 before replacing it.

catalytic combustible channel.

SELECT RELATIVE RESPONSE TO CALIBRATED GAS

FOR CATALYTIC SENSOR

You can select from a list of gases whose response relative to the configured gas, normally methane, is programmed into the EAGLE 2’s memory. This includes several pre-defined gases and 5 gases that can be entered into the EAGLE 2 in the field using the Eagle 2 Maintenance Data Loader Program. In order to program a field defined gas into the EAGLE 2, gas testing must be performed to determine the gas’ response factor relative to methane. See the Eagle 2 Maintenance Data Loader Program Operator’s manual for details regarding the gas testing and programming user defined gases into the EAGLE 2’s relative response list. The last five items in the gas list are reserved for field defined gases.

The relative response feature enables you to temporarily monitor for the selected gas without having to recalibrate the EAGLE 2. The EAGLE 2 will clear the gas configuration change when it is turned off and will return to the programmed configuration when it is turned on again.

Because of normal variation between sensors, these relative response factors are typical fact ors. If you use this featur e, the response to the selected gas will not be as accurate as it would be if you configured and calibrated the cataly tic combustible channel to the target gas.

NOTE: For maximum accuracy, configure and calibrate the EAGLE 2’s

catalytic combustible channel to the desired target gas.

The EAGLE 2 features the ability to log data to its internal memory and download it to a computer via the infrared communications port on the front of the unit. It logs gas readings during normal operation, alarm data, and calibration data.

CLEARED

To utilize the EAGLE 2’s downloading capability, you will need the Eagle 2

EAGLE 2 Operator’s Manual Data Logging • 53

Data Logger Management Program and a computer with an infrared port or a USB port that runs one of the following operating systems: Windows 2000, Windows XP, or Windows Vista. If your computer has an infrared port, then no additional accessories are needed to download data from the EAGLE 2. If your computer does not have an infrared port but does have a USB port, a USB/IrDA adapter cable can be used to download data from the EAGLE 2 using the USB port. The Eagle 2 Data Logger Management Program is available from RKI Instr uments, Inc. Th e adapter cable is also a vailable from RKI Instruments, Inc. or may be purchased from an electronic supply website.

The data logging capacity depends on how often the EAGLE 2 stores data, how many channels are active, and how often the EAGLE 2 is turned on and off. The table below illustrates how much data logging time is available for the various interval times. It assumes that the unit is setup with four sensors, is only turned on once, and there are no alarm occurrences. See “Updating the Data Log Interval Setting” on page 120 for instructions on setting the data logging interval time.

Chapter 4: Calibration Mode

Overview

This section describes the EAGLE 2 in Calibration Mode. In Calibration Mode, you can move through a menu of screens to do the following:

• Perform a span adjustment on all channels simultaneously using

auto calibration

• Perform a span adjustment on one channel at a time using single

calibration

• Perform a fresh air (zero) adjustment

NOTE: You can set up the EAGLE 2 to alert you during the startup

sequence when calibration is due. See “Updating the Calibration Reminder Setting” on page 122

CAUTION: BEFORE EACH DAY’S USAGE, SENSITIVITY IN THE

%LEL RANGE MUST BE TESTED ON A KNOWN CONCENTRATION OF THE COMBUSTIBLE TARGET GAS, METHANE, EQUIVALENT TO 25 - 50% OF FULL SCALE CONCENTRATION (the %LEL full scale is 100 %LEL). ACCURACY MUST BE WITHIN -0 to + 20% OF ACTUAL. ACCURACY MAY BE CORRECTED BY FOLLOWING THE CALIBRATION INSTRUCTIONS FOR THE COMBUSTIBLE CHANNEL BELOW.

If the combustible channel passes the above response test and does not require calibration, the unit should still be calibrated periodically. The optimum frequency of calibration depends heavily on how the EAGLE 2 is used. For example, instruments used daily may need to be calibrated weekly or monthly, while instruments that are used only a few times a year may need to be calibrated before each use. Typical calibration frequencies range from monthly to quarterly. Make sure to perform the combustible channel response test as described above and make sure to develop a calibration schedule tailored to your application that takes this test and required calibration resulting from this test into account.

EAGLE 2 Operator’s Manual Overview • 55

Calibration Supplies and Equipment

To calibrate the EAGLE 2, you will need:

• Known calibrating samples of the gases being detected. The combustible

and toxic gas samples should have concentrations between 10 and 50% of the full scale value. For example, if you are calibrating the catalytic combustible gas channel, your calibration cylinder should have a combustible gas concentration between 10% LEL and 50% LEL. An oxygen-free source, such as 100% nitrogen is recommended for setting the oxygen zero.

NOTE: The catalytic combustible channel can be set up for and calibrated to

a number of different combustible gases. See “Configuring the Combustible Gas” on page 108 for instructions. Be sure that you are using an appropriate calibration cylinder for the target gas of the catalytic combustible channel.

CAUTION: When using auto calibration with the standard 4-gas EAGLE 2,

although the EAGLE 2 can be calibrated with an oxygen concentration of up to 19.5%, RKI Instruments, Inc. recommends that the multi-gas cylinder have an oxygen concentration in the range of 10% - 16% oxygen.

• A demand-flow regulator to provide adequate sample gas flow

• Non-absorbent tubing

• A 24 inch humidifier tube if you are calibrating the catalytic combustible

channel with a gas concentration of 1000 ppm or lower

WARNING: If you are using a calibration kit that includes a gas bag and

a fixed flow regulator or dispensing valve, do not apply gas directly to the EAGLE 2 with the regulator or dispensing valve or damage to the pump will result. See “Appendix A: Calibrating with a Sample Bag” on page 86 for instructions to properly use a gas bag kit.

To calibrate the %LEL, oxygen, CO, and H

S sensors at the same time,

automatically, with no need for a zero-oxygen source, you can use the auto calibration feature with a 4-gas cyli nder . If the H

S channel is not active, then

a 3-gas cylinder may be used for auto calibration. This chapter includes instructions for auto calibration with a demand-flow regulator and a 4-gas

56 • C a l i b r a t i o n S u pp l i e s a n d E q u i p m e n t EAGLE 2 Operator’s Manual

cylinder . This chapter also includes inst ructions for calibrati ng one channel at a time using single calibration.

Replacing the Hydrophobic Filter

Replace the hydrophobic filter inside the bottom case when it becomes dirty or clogged. An unexplained low flow alarm may indicate that the hydrophobic filter is dirty and needs to be replaced.

1. Verify that the EAGLE 2 is off.

2. Place the EAGLE 2 upside down on a flat surface or hold it upside down.

3. Unscrew the three case screws until they disengage from the top case. They are captive screws so they will not fall off of the bottom case.

4. Turn the EAGLE 2 right side up and carefully lift the top case away from the bottom case. Be careful not to lift it so far that it pulls on the main PCB with the cable that connects the top case to the main PCB.

5. Lay the top case down next to the bottom case to allow access to the flow system.

7. Pull the grey connecting tubes off of each end of the filter and remove it.

8. Install the new filter with the red RKI logo and part number on the inlet side of the flow chamber, facing the front of the EAGLE 2. Make sure to push the grey connection tubes all the way onto the filter’s hose barbs.

9. Confirm that the main PCB is seated in its slots and that its bottom edge is resting on the bottom of the bottom case. If the main PCB is not seated properly, then it may be damaged when the top case is re-installed.

10. Make sure that the top case gasket is fully seated in its groove and carefully put the top case back on the bottom case. If you have any difficulty mating the top and bottom cases, inspect the placement of the main PCB and the placement of the top case gasket.

11. Turn the EAGLE 2 upside down and tighten the three case screws to secure the top case to the bottom case.

10. Confirm that the main PCB is seated in its slots and that its bottom edge is resting on the bottom of the bottom case. If the main PCB is not seated properly, then it may be damaged when the top case is re-installed.

11. Make sure that the top case gasket is fully seated in its groove and carefully put the top case back on the bottom case. If you have any difficulty mating the top and bottom cases, inspect the placement of the main PCB and the placement of the top case gasket.

12. Turn the EAGLE 2 upside down and tighten the three case screws to secure the top case to the bottom case.

Checking the Combustible Gas Sensor’s Condition

If you suspect that the combustible sensor has been contaminated or may be reaching the end of its operational life, do the following to confirm it is still operating properly:

1. Perform a calibration using single calibr ation as des cribed in “Calib rating Using the Single Calibration Method” on page 64.

2. When you perform the span adjustment, note the adjustment range on the result screen as described in Step 12 and Step on page 68.

3. A new sensor can typically be adjusted to more than twice the calibration gas concentration. If the result screen indicates that the EAGLE 2 could not adjust the combustible gas reading to be at least 10% higher than the calibration gas concentration, then the sensor should be replaced as soon as possible.

Appendix A: Calibrating with a Sample Bag

Overview

The EAGLE 2 can be calibrated with a gas bag calibration kit instead of a demand flow regulator kit. This appendix describes how to use a sample bag calibration kit to calibrate the EAGLE 2. A parts list at the end of this appendix lists spare parts for the calibration kit.

To calibrate the EAGLE 2, you will need:

• Known calibrating samples of the gases being detected. The combustible and toxic gas samples should have concentrations between 10 and 50% of the full scale value. For example, if you are calibrating the catalytic combustible gas channel, your calibration cylinder should have a combustible gas concentration between 10% LEL and 50% LEL. An oxygen-free source, such as 100% nitrogen is recommended for setting the oxygen zero.

NOTE: The catalytic combustible channel can be set up for and calibrated to

CAUTION: When using auto calibration with the standard 4-gas EAGLE 2,

• A gas collection bag with hose clamp

• A 6 LPM fixed-flow regulator or a dispensing valve

• Calibration tubing

To calibrate the combustible gas, oxygen, CO, and H time, automatically, with no need for a zero-oxygen source, you can use the

auto calibration feature with a 4-gas cylinder . If the H then a 3-gas cylinder may be used for auto calibration. This document

includes instructions for auto calibration with a fixed flow regulator or dispensing valve, a sample bag, and a 4-gas cylinder. This document also includes instructions for calibrating one channel at a time using single calibration.

Entering Calibration Mode

To enter Calibration Mode, do the following:

1. Find a fresh-air environment. This is an environment free of toxic or

combustible gases and of normal oxygen content (20.9%).
