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.
System Specifications Alkaline D cell battery, 75 hours operation. 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. Primary Power: Internal rechargeable NiCad battery, 6 hours operation. Standby Power: 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.
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.

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.
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.
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. 3.
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.
4 Programming and Advanced Features 4.1 Alarm Setpoints, Functions The Honeywell EC-P2 has three adjustable alarm setpoints. These setpoints are stored on each SMART-CELL. The Caution setpoint is to warn of excessive negative zero drift. The WARNING and ALARM setpoints are to warn of potentially dangerous target gas concentrations. The following procedure will change the WARNING setpoint. To Enter CAUT / WARN / ALRM Mode 1. Push power button to turn unit on.
Warning Function 4. Push WARN button. 5. Push FUNC (function) button. 6. Push SELECT button while viewing the arrow in the lower left hand corner of the screen to toggle through the following three possibilities: • UP arrow — Warn on increasing concentration (gas goes higher than setpoint). • DOWN arrow — Warn on decreasing concentration (gas goes lower than setpoint). • Blank — warning function turned OFF. 7. Push SAVE button when the DOWN arrow is displayed to store new warning function. 8.
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 5 above in which you would push the BLANK button. 4.
3. Push the MORE button. 4. Push the SMPL (sample) button and the unit is now in the SAMP / MEAS / CLEAR mode. SAMP Variable 5. Push SAMP (sample) button. 6. Push INC button (increase) or DEC button (decrease) until the display matches the desired value. The display is in minutes and seconds. 7. Push SAVE button to store new SAMP variable. To Exit SAMP / MEAS / CLEAR Mode 8. Push DONE button twice slowly to get back into normal operation mode.
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.
Each SMARTCELL has a wide range of choices of full scale values. Note: 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.

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.
