Prep Shelter for Purging

  • Open purge port
  • Open SPA vent

When using the generator the system will not allow the Main Shelter Breaker to be turned “ON” until a purging cycle is complete. This is a safety feature that does not function while using shore power.



Before turning the 60 amp power breakers on to power-up the shelter, you must check for the presence of flammable/explosive fumes. Assemble the portable gas detector as shown to the right and insert the wand into port in entry door to check for fumes.


Prepare Generator

  • Open covers and stow
  • Install main power cable and control line from APU/ECU
  • Also can be operated from shore power with provided shore power cable in the system.

Start Generator

  • Twist and pull stop button
  • Press Standby to turn control panel on
  • Press Generator Start/Stop once
  • Wait for start and voltage to reach 120VAC
  • Press “Purge”
  • Wait 3-4 minutes and light will go out

Press the Screen Shift button once to see the generator voltage output.


Establish Tent

  • Raise collapsed side
  • Drive stakes
  • Position Tent 4’-5’ centered behind shelter
  • Raise legs (4th hole)
  • Tighten ropes

Install Bootwall

  • Remove Ladder
  • One man on top
  • Place corners over lift eyes
  • Place over rubber pads
  • Secure straps to tent frame
  • Secure lower Velcro
  • Install ladder
  • Secure upper Velcro
  • Install inner support frame
  • Secure frame to shelter

Raise the Roof

  • Remove (4) pins that secure roof.
  • Remove roof socket plug.

Functions of the PQAS Software

Furnish a paperless environment to:

  • Enter petroleum sample information
  • Enter test results for a sample
    • Automatic entry – read data directly from instruments with RS-232 interface
    • Manual entry – of either:
      • Instruments without an RS-232 interface
      • Over-ride automatic entry with manual entry
  • Produce reports on the data

In a manner which will :

  • Be easy to use for the operator
  • Lower cycle time for testing
  • Provide a complete audit trail
  • Be reconfigurable to operational conditions
  • Simplify expandability and extensions

Instruments in the PQAS

Computer Interface



PQAS Data Entry Order

Ongoing operations:

  • Enter operator name
  • Enter new sample(s)
  • Run tests on sample(s)
  • Produce reports on samples and tests

Occasional admin operations:

  • Re-configure system
  • Perform database maintenance

After initial configuration, operations can be done in any order


New Sample Entry

  • You can simultaneously run any number of tests on any samples
    • The only restriction: you can not use an instrument again which is currently in use.
    • If you attempt to use an instrument twice, the PQAS software will warn you that you currently can not proceed with that test.

New Sample Entry Pulldowns

When done entering all samples click “Cancel” to return to main screen.

When done entering all the data for a sample, click “OK.”

System Overview

  • It provides a quick view of which tests are currently underway and which instruments are in use.
  • It provides a button to exit the “testing” (of “DAQ” – “Data Acquisition”) module of the software

Instruments in use or idle

Test currently in progress

Exit the testing mode of the PQAS software


Instrument Configuration

The Instrument Configuration function modifies information about an instrument, it’s characteristics and operating state. This includes:

Instrument name Serial number Test used for Operating State: Wiring Port Data comm details

  • Automatic/manual mode
  • RS-232 present
  • Is the instrument operating
  • When to use this function:
  • If the instrument is changed - record a new serial number
  • If the instrument malfunctions - change the operating state
  • The Data Acq module will only prompt for data on working instruments. It will set the “manual” or “automatic” data acquisition mode to match the entry in the configuration
  • If you change the wiring of the instrument to the Edgeport module –enter the new port number
  • Don’t modify the Data comm details unless particularly instructed.

Fuel Configuration

The fuel configuration module sets:

  • For a fuel type
  • Which tests are to be run for a specific test level
  • What are the acceptable test values to have pass a fuel sample.
  • This module can be used to:
  • Modify the particular tests to be run for a specified fuel and testing level
  • Modify the acceptable test values, if regulations have changed
  • Add a new fuel type to the PQAS system

The acceptable values for a test depend upon whether the source of the fuel is “IntraGovernmental” or not. This is reflected in two sets of columns in the table.



  • All data is stored in an Access database
  • Reports can be added or modified without affecting any other PQAS capabilities or any need to predefine them
  • You access the reports by running the report viewer program – “simple.exe”
  • Reports can be printed or saved in a number of formats
  • Reports can requests you enter data to limit range of the report

Running a Report

  • Run “Simple.exe”
  • Hit “Select Report” button
  • Choose the desired report

Simple.exe main screen


Report Parameters

Some reports require that you specify parameters

Our two example reports require the response to

the “Begin Date” and “End Date” for the data

If this box is “checked”, you will pick from a list of values from the whole database.

If unchecked, the pull-down button will produce a calendar to choose dates from.

Leave the box unchecked.
