Introduction

This manual has been prepared to help in the use of the Manning Systems EC-P2 portable gas detector.

This manual must be carefully followed by all individuals who have or will have the responsibility for using or servicing the sensor.

Warranties made by Manning Systems, Inc. with respect to this equipment will be voided if the equipment is not used and serviced in accordance with the instructions in this manual. If in doubt about a procedure, please contact Manning Systems, Inc. before proceeding.

1 System Description

The EC-P2 is a portable, battery operated instrument for the measurement of gas concentrations in ambient air.

The EC-P2 can be converted from one target gas to another by simply plugging in a different SMART-CELL for the desired target gas (takes about 30 seconds). This allows one instrument to detect a number of different gases. All calibration and alarm setpoint data is stored on the individual SMART-CELL so reconfiguration is not necessary when changing target gases. Extra SMARTCELLs should be kept on the optional sensor keeper when not in use to keep them “warmed up” and ready for immediate use.

The EC-P2 utilizes two different batteries to insure that you’ll never be without power when you need it. The primary power source is a “C” size alkaline battery housed in the handle. It will run the unit approximately 48 hours. When this battery is removed or dead, the unit will switch to its standby power source, an internal rechargeable NiCad battery, which will run the unit approximately six hours. When not in use, the unit should be plugged into the charger to keep this standby battery charged. If desired, the unit can be run continuously when plugged into the charger.

A Operating the Sensor

The EC-P2 is shipped ready for use. To power up the instrument, push the PWR button. The power up sequence displays first the self check, the sensor full scale value, the downscale caution level, warning concentration setpoint, alarm concentration setpoint, output ranges, software version, then the normal operating screen.

The unit will then display the instantaneous gas concentration and is ready for use.

The normal operating screen displays the information as shown in Figure 2.

using SMART-CELL Technology

4) Replace the manifold and hand tighten the thumbscrews.

5) Verify proper flow through the sampling wand using the

flowmeter provided.

Extra SMART-CELLS should be kept on the optional sensor keeper when not in use to keep them “warmed up” and ready for immediate use. The sensor keeper is powered by an Alkaline “C” size battery which should be replaced every 6 months.

For a variety of target gases, see page 13 for a list of available SMART-CELLs. Contact Manning Systems if the desired target gas is not listed, as new cells may be available.

Figure 2: Normal Operating Screen of the EC-P2 Sensor

The EC-P2 can easily be changed to sense another target gas by installing the SMART-CELL for the desired target gas. Each SMART-CELL contains all the calibration and alarm setpoint information on its internal memory chip, so recalibration or reprogramming is not necessary when changing the EC-P2 from one gas to another. This procedure can be performed with the unit powered on or off (see Figure 3).

1) Unscrew the two stainless steel thumbscrews and remove

cell and pull it straight out.

the socket. Notice that the SMART-CELL is keyed so it cannot be inserted incorrectly.

2 Operation continued

C Response Test

Prior to use, the unit should first be tested for proper response. With the detector operating, the unit should be exposed to a sample of the target gas. The display should show an increasing concentration. If not, do not use it for field measurements.

D Sample Inlet Port

The EC-P2 is provided with a quick disconnect flexible extension wand. It will work with or without the wand. When using the extension wand, the internal walls must be kept dry. Water on the walls of the tubing can potentially absorb the target gas. To dry, allow the unit to pump dry, ambient air for 15 minutes.

E Response/Recovery Time

Under normal conditions, the instrument will reach 90% of final value within two minutes. This is dependent on concentration and temperature.

Recovery time for the sensor depends on duration and concentration of exposure. Short exposures of concentrations at the lower end of the target gas range result in rapid recovery. Long exposures to levels above the middle of the target gas range or short exposures to levels exceeding the target gas range can extend recovery times to hours. Repeated exposures above the target gas range will reduce cell life and should be avoided.

F Interference Gases

The EC-P2 is generally quite specific to the target gas, but depending on the target gas, other gases may cause a reading. See Appendix B for a listing of potential interference gases for the various SMART-CELLs.

G Alarm Functions

The EC-P2 provides both visible and audible gas concentration alarms and system alarms. An alarm condition will be displayed on the normal operating screen as

described on page 5. In addition to the alarm indication code in the left side of the screen, an alarm message will flash intermittently on the screen, the audible beeper will sound and the ACK button will appear. Pushing the ACK button will silence the beeper and stop the display flashing. The Alarm Indication Code will remain on the left side of the screen until the alarm condition clears.

Alarm setpoints are stored on the individual SMARTCELL and can be changed by the user as described in Section 4.

Note: An audible alarm single beep every 60 seconds

indicates that either the Alkaline C cell battery is low or the internal rechargeable NiCad battery is low.

H Display Resolution

The EC-P2 displays gas concentration with a resolution that depends upon the range of the unit. Full scale ranges of 0-4.00 or below will provide resolution of 0.01. Ranges from 0-5.0 up to 0-49.9 will provide resolution of 0.1. Full scale ranges above 50 will have a resolution of 1.

3 Maintenance

A Periodic Maintenance

It is essential that the test and calibration schedule be adhered to. Manning Systems recommends the following maintenance schedule:

• Response test prior to each use. Expose sensor to

a sample of the target gas to verify proper sensor response and alarm functions.

• Calibration should be performed with certified

calibration gas every six months, and all tests must be logged.

• Check filter material every six months. Replace if

dirty or moist.

• If the optional sensor keeper is used for extra

SMART-CELLs, change the sensor keeper battery once every 6 months. Use only alkaline “C” size batteries.

B Sensor Life

The electrochemical SMART CELL is extremely reliable, but the following can cause the cell chemicals to become depleted:

• A period of time

C Calibration

Calibration is recommended every six months in normal use. Each SMART-CELL stores its calibration and alarm setpoint information on its own memory chip. When the SMART-CELL is plugged into the EC-P2, this information is used by the EC-P2. The SMART-CELL can be field calibrated by the user or returned to Manning Systems for factory calibration.

The calibration procedure requires the use of a bypass tee to allow the gas to be drawn into the flow cell without creating variable pressure or dilution problems. Calibration gas cannot be fed into the flow cell under pressure.

When applying calibration gas use the bypass tee as shown in figure 4 on page 8. The flowrate of calibration gas should be high enough that at least 0.5 SCFH is flowing out of the calibration tee. This can be measured with the supplied flowmeter and insures that air is not being drawn into the unit and diluting the calibration gas.

The unit may be zeroed without spanning it; however, never span the unit without first zeroing it.

The following procedure will calibrate the SMART-CELL.

• Exposure to high temperatures

• Exposure to high concentrations of the target gas

• Exposure to high moisture

When the cell becomes depleted, the unit will give no indication of failure other than that the sensor will not respond. For this reason it is absolutely essential that these units be exercised with a gas sample on a regular basis.

Typical sensor life under normal use is two years or more. When the SMART-CELL will no longer calibrate properly, simply purchase a new SMART-CELL and replace.

To Enter ZERO / SPAN Mode

1) Push power button to turn unit on. Wait for power up

sequence to finish (30 seconds).

2) Push and hold the unnamed button (second from left) first,

then Push and hold the Menu button. Hold both buttons until the screen goes blank (2 seconds). Release both buttons and the unit is now in Programming Mode.

3) Push the SENS button and the unit is now in the zero/span

mode.

3 Maintenance continued

Zero Calibration

4) Be sure the unit is in clean air or apply zero air for two

minutes.

Push ZERO button.

Push SAVE button to save the new zero calibration.

Span Calibration

7) Push SPAN button.

8) Apply span gas for two minutes.

9) Push INC button (increase) or DEC button (decrease) until

the display matches the span gas concentration.

10) Push SAVE button to store new span calibration.

To Exit ZERO / SPAN Mode

11) Push DONE button twice slowly to get back into normal

operation mode.

D Troubleshooting

The detector does not start: Check to see that a fresh

battery is installed. Both the primary and standby batteries must be discharged for this problem to occur. Plug the charger into the EC-P2 to charge the standby battery. Wait 10 minutes and retry.

The detector does not respond to the target gas: Verify

the proper flow rate using the supplied flowmeter. Perform calibration. If sensor won’t calibrate, the SMART-CELL may be depleted. Contact Manning Systems for a replacement SMART-CELL.

Pump alarm: This will occur if the pump motor stops

or if an internal pressure sensor detects blockage of the inlet. Check that the internal filter is not clogged or wet and that the inlet tube is clear.

External flowmeter indicates no flow: Verify that pump

is running. Check that the manifold screws are tight and the extension wand connection is tight.

Unit does not respond when keys are pressed: Press

and hold all four buttons for five seconds. This will reset the EC-P2. Turn the unit back on by pressing the PWR button.

High reading won’t clear: When the sensor is exposed

to very high gas concentrations, it takes a relatively long time for the sensor to clear. Leave the unit running in a clean environment for a few hours to clear the sensor. If it doesn’t clear after six hours, the sensor may have been damaged. Contact Manning Systems for a replacement SMART-CELL.

Unit is in alarm with gas reading of 0 ppm: Check the

alarm setpoints and alarm functions as described on page 9. Verify that alarm is not programmed as a downscale alarm, and that the setpoint is above zero.

B Display Variables

The EC-P2 has two adjustable display variables. These variables control signal conditioning of the LCD display. Variables are stored on each SMART-CELL. The AVG (Average) variable determines the number of one second samples to average to calculate the displayed value. The lower the averaging value, the faster the display will change and the more “wiggle” will be displayed. The BLANK (zero blanking) variable controls the lowest reading that will be displayed. This is to eliminate the misleading display of signals within the zero noise of the sensor. The following procedure will change the AVG variable.

To Enter AVG / BLANK Mode

1) Push power button to turn unit on. Wait for power up

sequence to finish (30 seconds).

2) Push and hold the unnamed button first, then Push and

hold the Menu button. Hold both buttons until the screen goes blank (two seconds). Release both buttons and the unit is now in Programming Mode.

3) Push the MORE button.

4) Push the DISP (display) button and the unit is now in the

AVG / BLANK mode.

AVG Variable

5) Push AVG button.

6) Push INC button (increase) or DEC button (decrease) until

the display matches the desired value.

7) Push SAVE button to store new AVG variable.

To Exit AVG / BLANK Mode

8) Push DONE button twice slowly to get back into normal

operation mode.

The Blanking variable is programmed in the same manner, except for step five above in which you would push the BLANK button.

C Sample Mode

The Sample Mode feature allows the user to take a measurement using a predefined repeatable method to eliminate user “interpretation” of a gas concentration that is changing. This is similar to a digital scale, for example, so the exact same reading will be taken regardless of who is taking it.

The measuring sequence used in Sample Mode is as follows:

• Draw a

time to allow unit to stabilize to the existing gas concentration.

Measure the gas concentration and average it for

•

a user programmed measuring time.

•

Clear the gas concentration to below a user

programmed recovery value before allowing another cycle to start. (Unit should be moved to fresh air during the clear time.)

Sample for a user programmed sampling

Taking a sample:

To take a sample, locate the detector at the desired sample location, and push the SMPL (sample) button on the normal operation screen. The unit will countdown the Sample time, followed by the Measure time, at the end of which the average value will be displayed.

Note the displayed sample value. Pushing the CLEAR

button will return the unit to the normal operation screen once the gas concentration is below the predefined recovery value. The unit is now ready to take another sample if desired.

8) Push DONE button twice slowly to get back into normal

operation mode.

The Measure and Clear variables are programmed in the same manner, except for step five above in which you would push the MEAS or CLEAR button.

D Data Logging

The EC-P2 can log periodic gas concentration readings to be downloaded to a file which can be read by Microsoft Excel or other popular spreadsheet applications. The EC-P2 will store instantaneous gas values every one, five, 10, or 15 minutes. Multiple sessions can be logged and then downloaded as separate files.

EC-P2 software installation:

The EC-P2 is supplied with a CD containing the “Manning Systems EC-P2” program. It will run on Windows 95, Windows 98, or Windows 2000. To install the program, place the disk in your CD drive. The CD should automatically begin the installation process. Follow the prompts as they appear on your screen. Accepting the default directory locations is recommended for most installations. If the CD does not automatically start, click on “My Computer” and then your CD drive. Double-click on the file named “Setup.exe.”

Prior to your first datalogging session it is recommended that you connect the EC-P2 to your computer with the data logging program running. The computer can then set the time in the EC-P2 to match its own clock.

Data logging with the EC-P2:

To Start the Data Logging Session

1) Push power button to turn unit on. Wait for power up

sequence to finish (30 seconds).

2) Push the MENU button.

3) Push the LOG button and the unit is now in the

CLEAR / INT / START mode.

4) If the CLEAR button is available, that means there is data

currently stored in the unit. If desired, you can erase the data already in the unit by pushing the CLEAR button. (If you don’t push CLEAR, each data logging session can be downloaded as a separate file).

5) Push INT button (interval) to cycle through the choices for

how often to log a data point. Stop when the desired interval is displayed. Notice how much time can be covered with the remaining free memory.

6) Push and hold the START button until the screen goes

blank (two seconds) to begin a new data logging session. The unit will now display the gas concentration. The Lg symbol in the left side of the display indicates that the unit is logging data. If you watch this symbol carefully, you will see it change to an “s” each time a data point is stored.

4 Programming and Advanced Features continued

To Stop the Data Logging Session

7) Push the MENU button.

8) Push the LOG button.

9) Push and hold the STOP button until the screen changes

to CLEAR / INT / START / MODE (two seconds).

10) Push the DONE button to get back into normal operation

mode.

Working with the “EC-P2” program:

The “EC-P2” program downloads the logging files from the EC-P2. It does not display the data. The files it downloads can be opened by or imported into Excel, Lotus 123 or other programs for graphing and analysis.

Turn on the EC-P2 and connect it to your PC using the RS-232 cable supplied. From Windows START menu, select “PROGRAMS,” then “Manning Systems EC-P2,” and then “EC-P2”. As soon as you start the “EC-P2” program, your computer will try to establish a connection to the EC-P2. If the EC-P2 is currently logging data, the “EC-P2” program will automatically stop the logging function.

The program contains two tabs, one marked “Download” and one marked “Configure”. Review the settings on the “Configure” tab, making changes as necessary.

From the “Download” tab, review the Link Status block in the lower right hand corner. It should indicate “Link OK”. Link Trouble can be caused by selection of the wrong Com port in the Configure Tab, improperly connecting the RS-232 cable, or not turning on the EC-P2.

E Analog Output

The EC-P2 has a 0 to 1.0 volt DC analog output capability when used with the optional analog output cable. With the analog output cable plugged into the communication port of the EC-P2, the user can measure the voltage between the two wires and correlate it to gas concentration. The voltage output will be linear between zero and the full scale range of the SMARTCELL as programmed below. Each SMART-CELL has a wide range of choices of full scale values.

The full scale range as programmed below only affects the analog output and the data logging full-scale output. The display will always cover the entire operating range of the SMART-CELL. Changing the range can affect the display resolution for some SMART-CELLs.

Changing the full scale range on EC-P2:

To Enter RANGE Mode

1) Push power button to turn unit on. Wait for power up

sequence to finish (30 seconds).

2) Push and hold the unnamed button (second from left) first,

then Push and hold the Menu button. Hold both buttons until the screen goes blank (two seconds). Release both buttons and the unit is now in Programming Mode.

3) Push the MORE button.

4) Push the DISP (display) button.

5) Push the MORE button and the unit is now in the RANGE

mode.

Adjusting the RANGE

When you are ready to transfer data from the EC-P2 to your PC, click on “get data” and the files will be downloaded to your computer. Note the file names in the destination window so you can locate the files.

These files can now be opened with Excel (use .csv filename), Lotus 123, or other user supplied programs.

6) Push RANGE button.

7) Push INC button (increase) or DEC button (decrease) until

the display matches the desired full scale range.

8) Push SAVE button to store new full scale range.

To Exit RANGE Mode

9) Push DONE button twice slowly to get back into normal

operation mode.
