Honeywell EC-P2 Instruction and Installation Manual  
 
1 System Description  
The Honeywell EC-P2 is a portable, battery operated instrument for the measurement  
of gas concentrations in ambient air.  
The Honeywell 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 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 Honeywell 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 “D” size alkaline  
battery housed in the handle. It will run the unit approximately 75 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.  
The Honeywell EC-P2 also has advanced capabilities such as data logging to an  
Excel spreadsheet, 0 to 1.0 Volt DC analog output capability, and a sampling mode  
for taking a single reading in a controlled, repeatable manner.

2.1 Operating the Sensor  
The Honeywell 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.  
Honeywell EC-P2 Instruction and Installation Manual

The normal operating screen displays the information as shown in Figure 2.  
The Honeywell EC-P2 is designed to avoid accidental shut-off of the power.To turn  
the unit off, the PWR button must be held down for approximately three seconds.  
Release the button after the “Power Down” message appears.  
2.2 Changing the Target Gas using SMART-CELL Technology  
The Honeywell 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 Honeywell  
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 the black inlet  
/ outlet manifold lid from the back of the unit.  
2. To remove the existing SMART-CELL, grip the sides of the cell and pull  
it straight out.  
3. Install the desired SMART-CELL by gently inserting it into the socket.Notice  
that the SMART-CELL is keyed so it cannot be inserted incorrectly.  
4. Replace the manifold and hand tighten the thumbscrews.  
5. Verify proper flow through the sampling wand using the flowmeter  
provided.  
Note:  
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 “D” size battery which should  
be replaced every 6 months.  
For a variety of target gases, see page 19 for a list of available SMART-CELLs.  
Contact Honeywell Analytics if the desired target gas is not listed, as new cells  
may be available.

2.3 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.  
2.4 Sample Inlet Port  
The Honeywell 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.  
2.5 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.

2.6 Interference Gases  
The Honeywell 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.  
2.7 Alarm Functions  
The Honeywell 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 8.  
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 D cell battery is low or the internal rechargeable NiCad battery  
is low.  
2.8 Display Resolution  
The Honeywell 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  
3.1 Periodic Maintenance  
It is essential that the test and calibration schedule be adhered to. Honeywell  
Analytics 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 “D” size  
batteries.  
3.2 Sensor Life  
The electrochemical SMART CELL is extremely reliable, but the following can cause  
the cell chemicals to become depleted:  
A period of time  
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.  
3.3 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 Honeywell EC-P2, this information is used  
by the sensor. The SMART-CELL can be field calibrated by the user or returned to  
Honeywell Analytics 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  
11.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.  
Honeywell EC-P2 Instruction and Installation Manual

Note:  
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.  
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.

6. 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.  
3.4 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 Honeywell 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 Honeywell Analytics 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.  
13  
Honeywell EC-P2 Instruction and Installation Manual  
 
 
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 Honeywell 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 Honeywell Analytics  
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 12. Verify that alarm is not programmed as  
a downscale alarm, and that the setpoint is above zero.

4.2 Display Variables  
The Honeywell 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.

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 5 above  
in which you would push the BLANK button.  
4.3 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 Sample for a user programmed sampling 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.)  
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 count down  
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.  
Programming sample mode variables  
The sample mode variables are Sample, Measure and Clear as described above.  
The following procedure will change the Sample variable.  
To Enter SAMP / MEAS / CLEAR 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.

To Exit SAMP / MEAS / CLEAR Mode  
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.  
4.4 Data Logging  
The Honeywell 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 Honeywell EC-P2 is supplied with a CD containing the “Honeywell EC-P2”  
program. It will run on Windows 98, Windows 2000 or Windows XP. 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 Computerand 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  
Honeywell 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 Honeywell 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).  
Honeywell EC-P2 Instruction and Installation Manual

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.  
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 Honeywell 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 Honeywell EC-P2 and connect it to your PC using the RS-232 cable  
supplied. From Windows START menu, select “PROGRAMS,then “Honeywell 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 Honeywell EC-P2. If the Honeywell EC-P2  
is currently logging data, the “EC-P2” program will automatically stop the logging  
function.  
The program contains two tabs, one markedDownloadand one markedConfigure”.  
Review the settings on the “Configure” tab, making changes as necessary.  
From the “Downloadtab, 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 Honeywell EC-P2.  
When you are ready to transfer data from the Honeywell 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.  
4.5 Analog Output  
The Honeywell 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 SMART-CELL as programmed below.  
19

Notes:  
1. None means there is no interference.  
2. A number indicates that when exposed to the interference gas, the sensor  
will react the specified amount for a given concentration. For example,  
on the first line of the table above, if the NO2 sensor is exposed to 1 ppm  
Bromine (Br2), the sensor will read 0.5 ppm.This interference is in addition  
to the target gas present.  
For example, if an NH3 sensor is exposed to 1 ppm NH3 and 1 ppm Br2 at  
the same time, the reading will be 0.9 ppm
