The traditional and real-time dust monitoring methods are described below.

Air is drawn by a vacuum pump through a 47mm diameter membrane filter
EPA FRM Style. The fibers and particles collected on the membrane filter
must be counted or weighed in a laboratory for further analysis.

• EPA or OSHA compliance reference method.

• High level of specificity and accuracy.

• Collection of dust particles, which are available for further chemical

analysis.

Dust particles are drawn into the sensor head and are detected once every
second. Dust concentrations are instantaneously calculated and displayed on
the SKC EPAM-5000’s LCD. All data points are stored in memory for later
analysis.

Advantages of
real-time
method

• Immediate estimations of the concentration of a contaminant, permitting

on-site evaluations.

• Provision of permanent 24-hour records of contaminant concentrations

using continuous monitors.

• Internal audible alarm to warn workers of approaching hazardous

situations.

• Reduction of number of manual filter tests.

• Reduction of number of laboratory analyses.

• Provision of more convincing evidence for presentation at hearings and

litigation proceedings.

• Reduced cost of obtaining individual results.

Real-Time Dust Monitoring Principles

Principles

• The SKC EPAM-5000 uses the principle of near-forward light scattering of

an infrared radiation to immediately and continuously measure the
concentration in mg/m

3

of airborne dust particles.

• This principle utilizes an infrared light source positioned at a 90-degree

angle from a photo detector.

• As the airborne particles enter the infrared beam, they scatter the light. The

amount of light received by the photo detector is directly proportional to the
aerosol concentration.

• A unique signal processes internally and compensates for noise and drift.

This allows high resolution, low detection limits and excellent base line
stability.

EPAM-5000.

Inability to Download Data to PC

Introduction

If DustComm Software installs properly but downloading instrument to
computer is unsuccessful try the following:

• Ensure that the RS232 cable connectors from the PC are tightly

screwed into place.

• Ensure that the communications settings are set appropriately in the

Download Properties screen of the DustComm program. Select Unit,
Properties to access this dialog box. The communications port must be
set to the appropriate Com Port used on the PC.

• If you are experiencing problems downloading your unit’s results to

your PC, and the RS232 cable connectors are secured tightly, your
cable may be connected to the wrong 9-pin port on your PC. If your
PC has more than one 9-pin connection port, attach the cable to
another 9-pin port and try to download the dust monitor’s results at
that port. You may need to try all of your PC’s 9-pin ports before
finding the correct connection.

• If the previous steps check out, try using the Windows supplied

HyperTerminal or other appropriately configured communications
software to receive data when downloading from the SKC EPAM-5000
Monitor.

• If using a USB port make sure you are using the proper USB to serial

adapter.

Checking the Calibration Span

Introduction

When to check
the calibration
span

Conditions

The Span Reference Insert Part Number CS-105 is a light scattering device
that provides a constant value (termed a “k” factor).

The Span Reference should be used as a reference to check factory calibration
of the EPAM-5000 Monitor.

The calibration span should be checked under the following conditions:

• Once a month with normal usage. (Normal use is twice a week).

• If the EPAM-5000 is dropped or otherwise damaged.

• The first time you use the unit to double check the factory calibration.

Note

: The EPAM-5000 can be sent to SKC. Annually recalibration

recommended in accordance with ISO and NIST procedures.

The following conditions must be met before checking the calibration span.

Condition... For further information

7 Insert the span reference into the sensor head (see diagram 5.1 on

page 5-2). Allow 2-3 minutes for reading to stabilize.

Note:

Be sure the locating pin on the calibration reference slides
into the locating hole on the sensor head. Also Push down on the
calibration reference to be sure it is aligned properly. Slightly twist
CS-105 clockwise when positioned in alignment hole. This will
ensure the CS-105 is in the exact position and ensure
reproducibility when “K” value is displayed on the EPAM-5000
monitor.

8 Observe the printed “k” value on the calibration reference.

Note:

The printed “k” value should match the concentration value
shown on the EPAM-5000 LCD to within + 10%.

Cleaning the Impactors

Introduction

Impactors should be disassembled and cleaned and greased at regular
intervals.

Example:

You should clean impactors every thirtieth sample or once a month
to start, but heavy loadings are observed on the target disk, as often as
appropriate.

Cleaning the
Impactors

Follow the Steps in the table below to clean the impactors.

Step Action

1 Pushing with a pen from bottom remove the impactor through

2 Rinse the impactor from top to bottom with a solvent

top of impactor sleeve into the palm of your free hand.

(hexane, white gas, lantern gas) using a squeeze bottle,
paying particular attention to the impaction target disks. An
acceptable alternative method of cleaning involves the use of
an ultrasonic bath with mild soapy water solution.

Note:

The impaction cup should be removed prior to re­greasing. This is accomplished by pulling the impaction cup
apart from the impactor jet gently.

3 Let all parts of the impactor air-dry.
4 Prepare a mixture of solvent and impactor grease (Apiezon ®

M, Glisseal

® Ht) or similar grease in a dropper bottle until

thoroughly mixed and of a fluid consistency. Use a 1-inch
length of grease to 30ml of solvent. Vigorously shake the
mixture until an opaque, uniform suspension, free from
grease globs, is obtained.

5 Put two or three drops of the solution on the impaction cup.

The drops should saturate the disk, flowing freely to the edge.

6 Let the impaction cup “dry” by allowing the solvent to

volatilize, leaving a thin film of grease on the impaction cup.

7 Replace the impaction cup onto the impactor jet. Re-insert

the impactor into the impactor sleeve.

Cleaning the Sensor Optics

Introduction

Cleaning the
Sensor Optics

Although the EPAM-5000 has an internal sensor purge it is important to keep
the sensor optics of the EPAM-5000 clean to ensure the integrity of the
optical sensor.

The sensor optics need to be checked every 2 months or on a weekly basis,
when used in a 2 to 3 mg/m

Follow the steps in the table below to clean the sensor optics.

Step Action

1 Remove the thumbscrews located on sensor cover. See Diagram

5-3.

2 Inspect internal sensor. Inspect cavities for residual dust. Use one

of the following methods to clean the surface. Blow the dust away
with low-pressure air or wipe with foam tipped cotton swab. See
figures 5-6, and 5-7.

3 Inspect the glass lens covers for dust.

Note:

Use one of the following methods to clean the glass lens.

• Blow the dust away with low pressure air, or,

• Use a small amount of isopropyl alcohol and wipe with cotton

swabs.

CAUTION: Do not spill any alcohol into the internal cavity of

the EPAM-5000.

4 Replace the sensor cover.
5 Tighten the thumbscrews snugly into place.

NOTE:

If thumbscrews are not tighten enough the flow of the

EPAM-5000 could be off.

If Instrument Does Not Respond

Introduction Check the following items if the EPAM-5000 Monitor’s LCD display is

incomplete, or the display and keypad are “locked up”.

Step Action

1 If the LCD display turns on, check the battery’s voltage. (Chapter 5

Section 5-8) A depleted battery will show a charge level of 5.95
VDC or lower. Replace the depleted battery with a fully charged
battery (Chapter 5 Section 10) or attach the appropriate power
transformer (Chapter 5 Section 9) to the EPAM-5000 Monitor.

2 If the LCD display does not appear, remove the battery (Chapter 5

Section 10) and check the voltage across positive pin and case
ground using a digital voltmeter. The battery should be recharged
(either inside or outside of the monitor) if it shows a charge level of

5.95 VDC or lower. Led battery indicator light should turn from red
to green when battery is fully charged or after approximately 15
hours of charging. If the battery voltage is higher than 5.95 VDC,
check the continuity of the 2-amp fuse in the battery pack at location
F1. If the fuse is blown, replace it with a new 2-amp replacement
fuse. If you do not purchase your replacement fuse from EDC, be
sure to replace this fuse with an identically rated component to avoid
damaging the monitor.

3 If the unit is “locked up” and the buttons on the keypad are non-

functional remove the battery (Chapter 5 Section 10). Other
symptoms of instrument lock up includes: Letters scrolling across the
bottom of the display or non-sensible lettering, display “locked up”
on preparing compensation or two lines across display. First remove
the battery and charge as stated in step 2. Then replace the battery
and check battery status, if it does not appear, it may be necessary to
reset the instrument. A reset switch is located inside the instrument
(NOTE: only use press the reset button as a last resort, all logged
data can be lost). Lift the sensor cover, inside of the instrument is a
push switch located on the PCB (see figure 6-2). Press reset switch
for one second and release. If unit resets it self check battery status
and date and time. If not, then press the switch and hold down as the
pump and solenoid purges. (This should take 30 seconds to 1
minute). Once purge is complete the switch can be released, remove
battery. Replace battery and check battery status (see chapter 5
section 8). If battery status does not appear repeat procedure. After
battery status appears it is necessary to reset date and time (see
Chapter 2 section 4) for the instrument to work. Note: Always
choose over write when beginning a sampling session.

If Memory Full Appears on Display

Step Action

1

• Clear the memory as described in Chapter 2 page 2-6.

• Lithium battery may have to be replaced. Please consult EDC

certified technicians.

• Batteries are covered 90 days under warranty.

6 - 4

Flow Rate Not Achievable

Perform the following checks if the flow rate of 4 LPM is not attainable.

• Air flow meter must be vertical to ensure accurate measurements.

• Air intake tubing is attached to filter cassette.

• Air may be leaking from the sensor covers on the front and right side of

optical sensor of the monitor. This can be tested quickly by operating the
unit (Chapter 3 page 3 -9) and placing your palm or thumb over the inlet
where the sample stream enters the unit. If this does not result in a
noticeable strain on the pump, it is likely that leaks exist around the sensor
covers or cassette holder. Remove the sensor covers and ensure the proper
cover placement front cover must be placed on front of sensor this cover
can be identified by the circular pattern on the gasket material of the cover
itself and reinstall them tightly. Cassette holder must have the white filter
holder ring installed and holder must be screwed on tightly to avoid air
leaks.

Inability to Download Data to PC

If instrument
will not
download to
PC.

If DustComm Pro Software installs properly but downloading instrument to
computer is unsuccessful try the following:

• Ensure that the RS232 cable connectors from the monitor and PC are

securely in place.

• Ensure that the communications settings are set appropriately in the

Communications Setup screen of the DustComm Pro program. The
communications port must be set to the appropriate COM port connector
used on the PC.

• If you are experiencing problems downloading your monitor’s results to

your PC, and the RS232 cable connectors are secured tightly, your cable
may be connected to the wrong 9-pin port on your PC. If your PC has
more than one 9-pin connection port, attach the cable to another 9-pin port
and try to download the monitor’s results at that port. Some PCs can have
up to eight 9-pin ports. You may need to try all of your PC’s 9-pin ports
before finding the correct connection.

• If the previous steps check out, try using the Windows -supplied

HyperTerminal or other appropriately configured communications software
to receive data when downloading from the EPAM-5000 Monitor.

If software does not install properly:

• Ensure DustComm Pro Software is being installed on the C: Drive

EPAM5000 Subdirectory.
