1. Description
The PHD6 is a multi-sensor gas detector that can be configured to meet a wide variety of user requirements. This chapter provides an overview of many of the features of the PHD6. More detailed descriptions of the specific features of the PHD6 are contained in the subsequent chapters of this manual.
1.1 Methods of sampling
The PHD6 may be used in either diffusion or sample-draw mode. In either mode, the gas sample must reach the sensors for the instrument to register a gas reading. The sensors are located at the lower front of the instrument.
The sensor ports must be
kept free of obstruction. Blocked sensor ports can lead to inaccurate and potentially dangerous readings.
In diffusion mode, the atmosphere being measured reaches the sensors by diffusing through the sensor ports at the front of the instrument. Normal air movements are enough to carry the sample to the sensors. The sensors react quickly to changes in the concentrations of the gases being measured. Diffusion-style operation monitors only the atmosphere that immediately surrounds the detector.
The PHD6 can also be used to sample remote locations with its hand-aspirated sample-draw kit or with its motorized, continuous sample draw pump. During remote sampling, the gas sample is drawn into the sensor compartment through the probe assembly and a length of tubing. Remote sampling operations only monitor the atmosphere at the end of the sample draw probe.
Use of the hand-aspirated sample draw kits is covered in section 3.1.
Use of the motorized sample draw pump is covered in section 3.2.
A detailed description of the PHD6 probe assembly is given in section 6.5
1.2 Multi-sensor capability
The PHD6 can be configured to simultaneously monitor oxygen, combustible gases and vapors, volatile organic compounds (VOCs), and a wide
variety of toxic gases. All sensors are replaceable in the field.
Note: The accuracy of the PHD6 must be verified by calibration with known concentration test gas whenever a change is made to the sensors installed in the instrument.
Calibration procedures are discussed in detail in Chapter 4.
The PHD6 can utilize a variety of sensor types to detect atmospheric contaminants including electrochemical sensors, PID (Photo Ionization Detector) sensors, NDIR (Non-Dispersive Infra­Red Absorbance) sensors and catalytic hot-bead LEL sensors.
Different measurement units are used depending on the gas being measured.

1.3 Calibration
The PHD6 detector features fully automatic fresh air and gas calibration.
The accuracy of the PHD6 should be checked periodically with known concentration calibration gas. Failure to check accuracy can lead to inaccurate and potentially dangerous readings. (The Canadian Standards Association (CSA) requires an accuracy check using known concentration calibration gas prior to each day’s use.)
Calibration procedures are discussed in detail in Chapter 4.
Recommended calibration frequency is discussed in Appendix B.
1.4 Alarm logic
PHD6 gas alarms can be adjusted manually using the PHD6’s built in menu functions, with
7
BioTrak II software via IrDA interface, or with the IQ Database Manager Program through the IQ6 Dock. (See Chapter 6 for direct menu programming instructions). Alarms may be set anywhere within the nominal range of the specific sensor. When an alarm set point is exceeded a loud audible alarm sounds, and the bright red LED alarm lights flash.
1.4.1 Atmospheric hazard alarms
PHD6 portable gas detectors have been designed for the detection of deficiencies of oxygen, accumulations of flammable gases and vapors, and accumulations of specific toxic gases. An alarm condition indicating the presence of one or more of these potentially life-threatening hazards should be taken very seriously. Failure to immediately leave the area may result in serious injury or death.
In the event of an alarm condition it is important to follow established procedures. The safest course of action is to immediately leave the affected area, and to return only after further testing determines that the area is once again safe for entry. Failure to immediately leave the area may result in serious injury or death.
A rapid up-scale reading followed by a declining or erratic reading may indicate a hazardous combustible gas concentration that exceeds the PHD6’s zero to 100 percent LEL detection range. Failure to immediately leave the area may result in serious injury or death.
The combustible gas alarms are activated when the reading for combustible gases exceeds one of the alarm setpoints. Combustible gas readings are typically given in terms of percent of LEL (Lower Explosive Limit), but may also be shown in terms of percent-by-volume methane (CH
4
). The PHD6 includes Warning and Danger alarms for the both the LEL sensor and the NDIR-CH
4
sensor. Two oxygen alarm set points have been
provided; a low alarm for oxygen deficiency and a high alarm for oxygen enrichment.
Up to four alarm set points are provided for the PID sensor and for each toxic gas sensor: Warning, Danger, STEL (Short Term Exposure Limit) and TWA (Time Weighted Average).
Appendix A discusses Warning, Danger, STEL and TWA alarms.
1.4.2 Low battery alarms
The PHD6 includes multi-staged alarms for both the Li-Ion and alkaline battery packs to let the user know that the battery is running low.
For detailed information concerning the low battery alarms, see section 2.5.5.
Use only Duracell MN1500 or Ultra MX1500, Eveready Energizer E91-LR6, Eveready EN91 batteries. Substitution of batteries may impair intrinsic safety.
1.4.3 Sensor over range alarms
The PHD6 will go into alarm if a sensor is exposed to a concentration of gas that exceeds its established range. In the case of an LEL or NDIR-CH
sensor reading that exceeds 100%
4
LEL, the sensor channel will be automatically disabled by the instrument and the instrument will remain in constant alarm until it is turned off, brought to an area that is known to be safe, and then turned back on. The display will show a vertical arrow with two heads in place of the sensor reading for any channel that has gone into over range alarm.
See section 2.5.2 for further details.
In the event of an LEL overrange alarm the PHD6 must be turned off, brought to an area that is known to be safe and then turned on again to reset the alarm.
1.4.4 PID lamp out alarm
The PHD6 monitors the status of the PID lamp to ensure that it is functioning properly. Alarms are generated if the PHD6 determines that the lamp is out. See section 2.5.3 for further details
1.4.5 LEL response failure due to lack of O
2
alarm
The PHD6 features automatic warning against LEL sensor response failure due to lack of oxygen. See section 2.5.4 for details.
1.4.6 Security beep/flash
The PHD6 includes a security beep function that is designed to notify the user that the instrument is powered up and running. Once enabled the PHD6 will emit a short audible beep and give a short flash on the LED at a user-defined interval.
The security beep/flash can be enabled manually through the Main Menu (see chapter 5), with BioTrak II software or through the IQ6 Dock.
1.4.7 Latching alarms
The PHD6’s alarms are self-resetting unless the alarm latch is enabled. With the PHD6’s alarm latch enabled, the audible and visible alarms will continue to sound after the atmospheric hazard has cleared. To reset the alarms, simply press the MODE button. If the alarm latch is disabled and the alarm condition is no longer present, the instrument will automatically return to normal operation, and the visible and audible alarms cease without further input from the user.
Latching alarms can be enabled manually through the Main Menu (see chapter 5), with BioTrak II software or through the IQ6 Dock.
8
1.4.8 Fault detection
PHD6 software includes a number of additional alarms designed to ensure the proper operation of the instrument. When the PHD6 detects that an electronic fault or failure condition has occurred, the proper audible and visible alarms are activated and an explanatory message is displayed.
Faults and other electronic safeguards are discussed in detail in section 2.5.
The PHD6 is designed to
detect potentially life threatening atmospheric conditions. Any alarm condition should be taken seriously. The safest course of action is to immediately leave the affected area, and return only after further testing determines that the area is once again safe for entry.
1.5 Other electronic safeguards
Several automatic programs prevent tampering and misuse of the PHD6 by unauthorized persons. Each time the detector is turned on, the PHD6 automatically tests the LED alarm lights, audible alarm, internal memory and pump status (if so equipped). The battery is monitored continuously for proper voltage. The PHD6 also monitors the connection of sensors that are currently installed. The detection of any electronic faults causes the activation of the audible and visible alarms and causes the display of the appropriate explanatory message.
1.6 Sensors
The PHD6 can be configured to simultaneously monitor oxygen, combustible gases and vapors, volatile organic compounds (VOCs) and a number of toxic gases. The sensor configuration of the PHD6 may be specified at the time of purchase, or changed in the field by appropriately trained personnel.
The PHD6 must be calibrated following any sensor replacement.
Replacement sensor part numbers and sensor ranges are given in Appendix C.
A sensor that cannot be calibrated or is found to be out of tolerance must be replaced immediately. An instrument that fails calibration may not be used until testing with known concentration test gas determines that accuracy has been restored, and the instrument is once again fit for use.
Calibration procedures are discussed in detail in Chapter 4.
1.6.1 Cross Sensitivity
Sensor cross-sensitivity figures are given in Appendix D.
The CO channel in the Duo-Tox sensor in the PHD6 may exhibit high levels of cross sensitivity to organic vapors (VOCs). For best performance
in an atmosphere known to contain VOCs, use a dedicated CO sensor.
1.7 Optional sample draw pump
A motorized sample-draw pump is available for the PHD6 for situations requiring continuous "hands free" remote monitoring.
The PHD6 continuous sample draw pump (part number 54-54-102) is the only pump that can be used with the PHD6.
The pump contains a pressure sensor that detects restrictions in airflow caused by water or other obstructions being drawn into the unit and immediately acts to turn the pump off in order to protect the sensors, pump, and other PHD6 components from damage.
Pump status is continuously monitored by the PHD6 microcontroller. When the pump is active and functioning properly, the spinning pump icon is displayed in the status bar at the bottom of the display. Low flow or other pump fault conditions activate audible and visible alarms and cause the display of the appropriate explanatory message.
1.7.1 Special precautions when using the
PHD6 pump
The rubber material used in the PHD6 diaphragm pump is susceptible to temporary compromise by exposure to high levels of flammable fuel and solvent vapors. If the PHD6 is being used to sample atmospheres that exceed 50% LEL, test the pump frequently to ensure that pump function has not been compromised.
To test the pump, block the end of the sampling line (probe) inlet with a finger. The pump should quickly go into alarm, which indicates proper function. If the pump fails to go into alarm while the inlet is blocked, it is not working properly; and the PHD6 may not be providing an accurate reading. If the pump test fails, the safest course of action is to immediately leave the affected area and to return only after further testing with known, functional detection equipment confirms that the area is once again safe for entry.
Do not use the pump to sample for prolonged periods in conditions where the concentration of solvent or fuel vapors may be greater than 50% LEL.
1.8 Data storage
The PHD6 includes a black box data recorder and an event logger as standard features. A full datalogger is available as an upgrade at any time.
9
1.8.1 Black box data recorder
A black box data recorder is a standard feature in the PHD6. The “black box” is continually in operation whether the user is aware of it or not. The black box stores important information such as gas readings, turn-on times, turn-off times, temperatures, battery conditions, the most recent calibration date and settings, types of sensors currently installed, sensor serial numbers, warranty expiration and service due dates, and current alarm settings.
There is a finite amount of memory storage available in the black box data recorder. Once the memory is “full”, the PHD6 will begin to write the new data over the oldest data. The black box data recorder will store a minimum of 63 hours of data in one-minute increments before it begins to write new data over the oldest data. In this way, the newest data is always conserved.
To extract the information from the black box data recorder, the PHD6 must be returned to Honeywell Analytics. Once the data is downloaded from the instrument, a report will be generated. The unit and the report will then be returned to the user. Simply call Honeywell Analytics’ Instrument Service Department to obtain a return authorization number. There is no charge for the downloading service, but the user is responsible for any freight charges incurred.
The “black box” data recorder in the PHD6 can be upgraded to a fully enabled datalogger at any time. All that is required is the activation code that corresponds to the serial number of the PHD6 and the PHD6 Upgrade Utility Program.
1.8.2 Event logger
The event logger in the PHD6 stores data associated with alarm conditions. Each (alarm) event includes the following data for each of the installed sensors:
Sensor type
Max reading
Average reading
Start time
End time
Duration of the event.
The PHD6 stores the data from the 20 most recent alarm events. Once 20 events have been stored, the PHD6 will begin to systematically overwrite the data from the oldest event in memory with data from new events. One event may be a combination of different alarms occurring simultaneously or in immediate succession. The event logger may be downloaded using BioTrak II software. The PC must be equipped with IrDA to provide a connection.
