SECTION TWO: Introduction

2.1. Product Description

The GilAir Plus is an advanced personal air sampling pump system available in three models: a basic model, a datalogging pump (DL) model, and standard temperature and pressure (STP) model. The STP model corrects the display flow rate and air volume to standard conditions of temperature and pressure. The STP model can also correct pump flow rate to keep flow constant with changes in barometric pressure and ambient temperature.

All models offer constant flow modes and constant pressure control modes. The Constant Flow Mode holds the set flow constant against changing backpressure within 5% or 3 cc/min whichever is larger. The Constant Pressure Mode holds the pressure constant when taking samples using constant resistance sampling trains. The constant pressure (multi-flow) mode allows the air stream to be split into two or more separate samples so that multiple samples can run at the same time. (See Appendix D for information on the dual port manifold) Furthermore, all models offer a built-in low constant flow mode, such that flow rates are attainable from 20 cc/min to 5100 cc/min without the addition of an external low flow adapter. Operation down to 1 cc/min is possible in the constant pressure mode. Additionally, all models offer start-stop programmability. A matrix chart for the available pump models are shown above.

*Note: SmartCalSM Automatic calibration is only available on all pump models when used with a communications-enabled Dock. The standard Dock that comes with the basic pump does not have communication capability and will not support the SmartCal feature.

See Appendix F for part numbers for pumps, kits and accessories.

Page 8

Gilian GilAir® Plus Air Sampling Pump – Operation Manual

SECTION THREE: Set-Up

3.1. Preparation

The package includes the pump, Dock, Dock power supply, and a line cord. The Dock serves as the charging base for all models and the communications Dock for the datalogging and STP models.

Plug the power supply into the Dock and the AC power cord into the power supply. Connect the AC power cord to mains supply. The supply can accept 100-240 VAC at 50 or 60 Hz.

The pump arrives fully assembled.

IMPORTANT

Before proceeding, you MUST charge the battery to full capacity prior to using the pump. To charge the pump, place it onto the charging base. The pump’s belt clip secures the pump in place. Connection is made via contact points on both sides of the belt clip.

Allow up to five hours for a complete charge. A red LED on the pump indicates charging in progress; a green LED indicates charged and ready for use. The green LED will flash during top off charge and is on constantly while on trickle charge. For more information on charging, see Appendix H.

3.2. Pump Start Up

3.2.1. Power Up

Power pump on by pressing and holding down (about 2 seconds) the button until the pump turns on.

3.2.2. Startup sequence

As the pump starts it goes through a number of phases that check for correct pump operation and special situations at startup.

Startup Phases:

1. Power verification: Before starting the voltage from the power source

(battery or DC) must be more than 6.3v. A display screen notifies the user when the voltage is low and displays the voltage. This typically occurs when a deeply discharged battery is placed on the Dock during the initial charge phase to bring the battery to adequate voltage for powering the system.

Page 9

Datalog Index:

Datalog is checked for validity and the index is created. The number displayed is the number of events in the datalog

Calibration:

The system calibrations are checked for validity.

Point Cal:

Flow calibrations are checked for validity.

System setup:

The block of memory containing the user set parameters is checked for validity.

Programs:

The user program area is checked for validity.

2. Dock position determination: When starting up on a Dock, the system

pauses briefly to let the Dock provide the Dock position for use with the PC App. If no position is available after 45 seconds, a message appears asking the user to reseat the Dock.

3. Serial number display: The next display shows the product type (Basic,

Datalog or STP), the serial number and the software revision for about 5 seconds.

4. System initialization: During system initialization the memory is read and

checked for validity in the following sections.

5. Date Check/Set: If the current system date and time is earlier than the last

date/time stored, this message appears to remind that the date should be reset.

3.2.3. Power Source Check

When the pump is charging on the Dock and the Dock status is being displayed, the charge status reported from the Dock is compared to the type of battery that is installed on the pump. If there is a discrepancy, the pump will signal the user by flashing the backlight and show a message asking for the pump to be removed. This is done to prevent the Dock from charging the battery in an inappropriate manner, which could result in the battery not being charged or being overcharged.

3.2.4. Power Down

Turn power off from any display when the pump is not running by pressing and holding down the button. After approximately two seconds a power down

display will appear and a five second shutdown sequence will start. If the button is released before the shutdown sequence is complete the power will not switch off. At the termination of the shutdown sequence, power is off.

Note: Power cannot be shut down if a sample or program is running.

Page 10

Gilian GilAir® Plus Air Sampling Pump – Operation Manual

3.3. Setting the Flow Rate

On the main menu, use the button to move the cursor to Flow Set. Adjust the flow rate to the desired value using the and buttons. Press and release the

button to confirm the change.

3.4. Power Options

The GilAir Plus comes standard with a rechargeable nickel metal hydride (NiMH) battery pack. The unit is charged through the Dock that is included with all starter kits.

An optional alkaline battery pack (P/N 783-0013-01-R) is available that allows the use of over-the-counter AA batteries.

A third option, the DC power pack (783-0014-01-R) allows extended run times with the pump on the Dock for pumps with firmware versions up to revision 2.4. Pumps that have firmware version 2.4 or higher are supplied version 3.5 Docks that support running for extended periods of time while charging on the Dock without the need for the separate DC power pack.

Note: Do not attempt PC communications with the Dock, when running a sample, calibrating, or editing pump settings.

Warning: Alkaline batteries, lithium batteries and the DC power pack should only be used in non-hazardous areas. Intrinsic safety certifications are only valid when using the rechargeable NiMH battery pack.

Gilian GilAir® Plus Air Sampling Pump – Operation Manual

SECTION FOUR: General Operation

4.1. Overview

The GilAir Plus has the capability of generating and controlling flow over the range of 20 cc/min to 5100 cc/min in two flow ranges, 20-445 cc/min, and 450-5100 cc/min, that are selectable using a 2 mm or 5/64 inch hex key (provided with the pump). The actual flow is measured and controlled by the pump’s internal processor. Flow control is provided directly in the constant flow mode. Pressure control is provided in the constant pressure control mode, which controls flow indirectly. During a sampling event the flow rate is displayed in the constant flow mode and backpressure is displayed in the constant pressure mode. Pump flow is not displayed in the constant pressure mode. The STP models measure the ambient temperature and pressure and can correct sample volumes and flows to Standard conditions. Standard temperature and pressure can be set to desired values. In addition, if enabled, the flow rate can be compensated for changes in temperature and pressure from the calibration point, holding the calibration value against altitude induced variability. (Appendix C)

4.2. Connections

Sample media is connected to the inlet port using ¼ inch ID tubing. Adapters that cause high pressure drop or using smaller diameter tubing may affect the sample flow. Minimize pressure drop in tubing and fittings and avoid any condition that will exceed the pump backpressure specifications (see Appendix E). The input port is part of the input manifold that provides input connection, output connection and contains a filter that protects the pump from contamination by particulates if operated without an effective sampling filter. This filter is user replaceable and should be replaced if discolored, clogged or obstructed in any way.

An output adapter accommodates filling sample containers such as Tedlar or Kynar sampling bags. Connect the bag fill adapter as shown below. The connection is sealed with a precision taper and should be inserted only finger tight. The knurled handle will not seat flush to the surface of the pump and should not be forced. The sample bag attaches with ¼ inch ID tubing. If the pressure in the bag increases, such as when it is completely filled, the pressure increase will be shown as increased pump backpressure and will terminate the event if the backpressure specification is exceeded.

4.3. Navigation

The GilAir Plus pump uses an intuitive six-button keypad for menu navigation and pump operation. The buttons and their functions are summarized in the table below.

4.4. Menus

The operation of the pump is controlled by entering the menu system and selecting the menu item that performs the desired function. The menu has submenus that allow control of related functions. A quick reference menu outline appears in Appendix A.

When the menu is not displayed, the and buttons select among the display screen options. The display screens are automatically selected by the pump whenever the mode of operation is changed (example: when an event is started or a fault occurs). The display screens include the Idle display, the Constant Flow control operating display, the Constant Pressure control operating display, the Fault display, Program Status display and STP Display (STP Models only). A description of the data displayed on each menu screen is contained in the Displays section (Section 4.5. ) of this manual.

Sampling events: The GilAir Plus accumulates sample data on events. An event is a sample run. The data for each sample event is stored as the event progresses so that no data loss is possible. When a sample is started, the event data is cleared to begin the new event. As the pump samples, the flow is controlled at the event flow rate or pressure depending on the selected control mode. The event data (time, flow, volume, backpressure and other information) is stored into nonvolatile memory.

If the pump is paused the event is not terminated. When the event continues, volume and time accumulation continue in the same event. If the event is stopped, the run data is available for review (Section 6.10. ) and in the idle screen until another event is started. The data from the last 16 events is available in the data review menu.

General operation of the menu system: Access the menu by pressing the

button. The menu is displayed in a vertical column. Some menu items have a ► sign after the menu item and lead to submenus. When the selected menu has the ►,

pressing the button enters the submenu. Pressing the button exits the submenu and returns to the higher level menu. If a parameter is displayed at the right

end of the line, the and buttons may be used to adjust the parameter up and down. If a parameter is changed it will be retained only if the button is pressed to

confirm the change. If a parameter has been changed, an ▲ symbol (for an increase in the parameter), or a ▼ symbol (signifying a decrease) is displayed to alert that the

button is required to confirm the change. If the menu selection is altered with the or buttons without confirmation with

the button, the parameter will revert to its original value. If the value is numeric, the and buttons alter the numeric value. If the

parameter is a selection, the buttons will select each option in sequence. The option may require the and buttons to select. For instance, the “enable” selection is always made by the button and the disable option is selected with the button.

NOTE: Several parameters have numeric values, allowing the user to scroll through the entire range by simply pressing and holding down either the and buttons. In addition to this feature after pressing and holding the or button, the and

buttons will accelerate the rate of scrolling. The button moderately and the button quickly accelerates the rate.

4.5.1. Display Details

1. Date and time: Displayed in selectable format mm/dd/yy or dd/mm/yy

2. Battery icon: The NiMH battery pack is identified by an "N" to the left of the

icon, the AA replaceable pack is identified by an "A". When using a NiMH or AA battery pack the charge state of the battery is shown. If the pump is using a DC power pack on the Dock, "DC" is shown. Charge status is approximate and depends on many factors including age, number of charge cycles, temperature and recent charge or discharge history.

3. Flow range indicator: Displays "Hi", "Lo" or "Err" at all times. This indicator

shows the setting of the flow control valve, which determines high range or low range operation of the pump. When the indicator shows "Err", the valve is between positions and must be moved to the correct detent position to operate the pump.

4. Control mode: Displays the event control mode of the pump, either constant

flow (CF) or constant pressure (CPH or CPL). In constant flow mode, the pump controls the flow rate regardless of changes in the filter load (backpressure). In constant pressure, the pump controls the inlet pressure, regardless of the flow. The constant pressure modes, CPH and CPL, allow the user to select the range of expected flow for optimum control.

5. Run mode: Displays the status of the Run mode, which indicates how the

pump’s sampling schedule is set. There are five modes; manual, the

operator turns the pump on and off; timed, the pump turns on at a preset time and off at a specified number of minutes later; Vol, the pump turns on at a specified time and collects a specified volume; RT, the pump turns on at a specified time and runs for a specified number of minutes of run time, and program, indicated by the name of the program, operating under the timing control of a user defined program which specifies on and off times and durations.

4.6. Sensor Calibration

The GilAir Plus pump has a built in automatic sensor calibration feature which allows the pump to maintain an accurate stable flow rate by intermittently calibrating the pump’s flow sensor to establish the zero flow point. This routine occurs before starting, when the internal temperature of the pump changes more than 3 degrees C, or whenever one hour has elapsed since the last sensor calibration, depending on the Sensor option setting (Section 5.12.3. ). The calibration takes approximately 20 seconds during which time the pump stops running. Sample time and volume are not counted during the sensor calibration routine as the pump automatically accommodates this brief stoppage in the accumulation of sample results. The message "Sensor Calibration" displays during this process. The sensor calibrations eliminate the effect of sensor drift on flow rate stability. If the sensor calibrations are reduced or eliminated (Section 5.12.3. ) flow stability may be affected.

4.7. Run Mode

4.7.1. Run Mode Descriptions

Selecting Run begins a sampling event. The previous event data is cleared. Before selecting Run, the control mode, constant flow or constant pressure should have the proper setting and the flow rate or control pressure should be at the desired set point. If Manual Run Mode is active, the pump starts in the selected control mode at the set point. If the Timed Run Mode is selected, the pump waits for the start time and then starts and runs until the start time plus the specified duration. If the Vol Run Mode is selected, the pump waits for the start time and then starts and runs until the specified volume has been collected. If the RT Run Mode is selected, the pump waits for the start time and then starts and runs until the run time has elapsed; this does not count pauses, sensor calibration intervals and fault stop times. If the Program Run Mode is selected, the program starts and controls sampling until the program completes. When running in the high flow mode, a “Connect Media” message will pop up on the screen periodically if the pump does not see the expected backpressure caused by a sample train.

Note: The pump is designed to operate with a minimum backpressure of 2” H2O while in the high flow mode. Operating the pump in high flow mode without any collection media attached or at a backpressure of less than 2” H2O will result in inaccurate performance.

When the Run menu item is selected, readiness to start the event is evaluated. If the pump is using battery power, the battery status is checked. If the battery has less than about 5% of remaining charge, the event will not start. If the battery has less than 90% charge, a message box will appear to warn that the battery is not fully charged.

Page 21

Gilian GilAir® Plus Air Sampling Pump – Operation Manual

The recirculation valve is checked for proper position. If it is incorrectly positioned, a popup message will alert the user. If the valve is moved to the correct position, the event start evaluation will continue. If the ESC button is pressed, starting the event will be abandoned and control will return to the menu.

The Event log is checked for available space. If space is not available, a message will warn the user. If the ESC button is pressed, starting the event will be abandoned and control will return to the menu to allow the data to be recorded or downloaded before continuing. If ENTER is pressed, the pump will enter the clear datalog dialog and allow the datalog to be cleared. If the datalog is not cleared the event cannot begin. If the datalog is cleared, the event will start.

If the Event ID option is enabled, the user will be prompted to enter an Event ID, which will be stored with the event data for later review or download.

If the Pre/Post Cal option is enabled, a Pre-Cal flow calibration will start. If the ESC key is used to exit the Pre-Cal flow calibration, the event will start without adjusting the flow rate or recording a Pre Pre-Cal reading. The preset SmartCal device will be used if the pump is on the Dock, otherwise a manual calibration will be performed.

The Stop menu can be accessed by the button during Run to pause or stop the event. If Pause is activated the pump stops with flow, timing, and total volume accurately maintained. The menu changes to allow continuation of the event. The Stop menu item terminates the sample event. The keypad can be locked to avoid event modification as described in the next sections.

4.7.2. Locking the Keypad

To lock the keypad: Press and hold down simultaneously the and buttons. A lock symbol will

appear in the top status line. Release the buttons and the pump will be locked. After locking the pump it will only respond using the and buttons to access the

Idle, Fault, Program and Standard Conditions status screens. Warning: If a password is in place to restrict access to the pump, it will have to be entered to unlock the pump. Be certain that you know the password before you lock the pump.

4.7.3. Unlocking the Keypad

To unlock the keypad: Press and hold down simultaneously the and buttons. The lock symbol will

disappear from the top middle portion of the screen. Release the buttons, and the pump will be unlocked.
