Confined space precautions

D A N G E R

Explosion hazard. Training in pre-entry testing, ventilation, entry procedures, evacuation/rescue
procedures and safety work practices is necessary before entering confined spaces.

The information that follows is supplied to help users understand the dangers and risks that are
associated with entry into confined spaces.

On April 15, 1993, OSHA's final ruling on CFR 1910.146, Permit Required Confined Spaces, became
law. This standard directly affects more than 250,000 industrial sites in the United States and was
created to protect the health and safety of workers in confined spaces.

Definition of a confined space:

A confined space is any location or enclosure that has (or has the immediate potential for) one or
more of the following conditions:

• An atmosphere with an oxygen concentration that is less than 19.5% or more than 23.5% and/or a

hydrogen sulfide (H2S) concentration that is more than 10 ppm.

• An atmosphere that can be flammable or explosive due to gases, vapors, mists, dusts or fibers.

• Toxic materials which upon contact or inhalation can cause injury, impairment of health or death.

Confined spaces are not designed for human occupancy. Confined spaces have a restricted entry
and contain known or potential hazards. Examples of confined spaces include manholes, stacks,
pipes, vats, switch vaults and other similar locations.

Standard safety procedures must always be obeyed before entry into confined spaces and/or
locations where hazardous gases, vapors, mists, dusts or fibers can be present. Before entry into a
confined space, find and read all procedures that are related to confined space entry.

N O T I C E

Measurement errors can occur due to electrical transients from sources such as lightning or large electrical
motors. These errors can cause unexpected sample acquisition or a missed sample when the controller is
programmed for setpoint sampling based on sonde measurements. Use a power line filter or connect the
controller to a different branch circuit to reduce the possibility of transients.

The controller supplies power to the SDI-12 device. Use the 15 m (50 ft) cable or the 30 m (100 ft)
cable to connect a sonde to the controller. Refer to Figure 10.

Note: A separate power supply for the sonde is necessary for data logging by the sonde.

The SDI-12 interface is enabled only when a connected device is found by the controller. The scan
for a sensor occurs automatically. The address that is assigned to the SDI-12 device is automatically
detected by the controller.

Constant Time Variable Volume (CTVV) sampling

CTVV samples are taken at user-specified constant (fixed) time intervals. However, the actual
volume of each sample is based on the:

• Known average flow rate of the site

• Actual metered flow rate at the time of sampling

• Total sample volume desired

• User-specified collection period

• Specified sampling interval

The volume of individual sampling can vary and depends on the flow volumes of the stream at
various intervals within the collection period. The total sample collected during the entire period can
be slightly above or below the necessary total volume. For these reasons, the manufacturer
recommends that a sampling container is used that has a larger volume than the necessary total
volume. When CTVV is used for sampling:

• Sample distribution menus are not available when CTVV is selected, only composite sampling is

supported.

• The liquid sensor is always enabled.

• The sample distribution is composite.

• The run mode is non-continuous.

• The first sample is taken after the interval.

• Flow source is always 4–20 mA input.

The instrument finds the sample volume, based on user inputs and actual metered flow volume. For
example, the entered values are:

• Average flow rate (historical, site specific): 150 gph

• Sampling interval: 2 minutes

• Total sample volume desired: 1500 mL

• Collection period: 30 minutes

Calculation 1: Total number of samples

Collection period ÷ Sampling interval = 30 minutes ÷ 2 minutes = 15 samples

Calculation 2: Average sample volume

Total sample volume desired ÷ Total number of samples = 1500 mL ÷ 15 Samples = 100 mL/sample

Calculation 3: Sample volume per unit of flow rate

Average sample volume ÷ Average flow rate = (100 mL/sample) ÷ 150 gph = 0.66 mL/gph

Calculation 4: Collect actual sample volume

• If the 4–20 mA flow source is used and the flow rate measured is 140 gph, use sample volumes

per unit of flow rate x actual metered flow rate.

0.66 mL/gph x 140 gph = 92.4 mL. The sampler will pull a 90 mL sample (rounded off from

92.4 mL).

• If the flow pulses are used and every pulse count is 2 gallons and 2 counts are received in

2 minutes, the flow rate is 120 gph.
Sample volumes per unit of flow rate x actual metered flow rate

0.66 mL/gph x 120 gph = 79.2 mL. The sampler will pull a 80 mL sample (rounded off from

79.2 mL).

Volume calibration

The sample volume can be calibrated automatically with the liquid sensor or manually. When the
liquid sensor is used for volume calibration, the sensor is adjusted to accurately measure all
programmed volumes. If the liquid sensor is disabled, the volume for samples, rinses and stormwater
must be calibrated manually.

For typical applications, tap water can be used for the volume calibration. If the sample composition
is significantly different from typical water samples, calibrate the sampler with the liquid to be
collected. All programs must be stopped before calibration.

Calibrate the liquid sensor

The accuracy of the liquid sensor varies with the type of liquid that is sampled. For example, the
volume of a highly turbid sample may not be as accurate as that of clear water. The liquid sensor can
be calibrated with the sample water to improve volume accuracy.

select END AFTER LAST.

If it is necessary to run timed bottle in continuous mode, disable the full bottle shutoff.

Full bottle shutoff exception conditions

Full bottle shutoff does not prevent bottles from being over or under filled when certain exception
conditions occur. Such conditions can occur if:

• The liquid sensor is disabled and the manual calibration is incorrect.

• The liquid sensor is enabled but does not operate correctly or has bad calibration.

• Bottles are emptied but the program is not halted (controller does not know bottles are empty and

activates full bottle shut off too soon).

• The program is halted but the user gives incorrect feedback:

• Bottles are empty but the user selects NO in the BOTTLES EMPTIED? screen.

• Bottles are not empty but the user selects YES in the BOTTLES EMPTIED? screen.

Advanced sampling

Send output signal at program completion

A 12 VDC signal can be sent through pin F of the auxiliary connector at the completion of a sampling
program or when the full bottle shut-off is activated. The signal stays on for 61 seconds.

The output signal can be used to:

• Start another sampler. Cascading samplers require a cascading cable (8757300). The slave

sampler must enable setpoint sampling and start on an external trigger.

• Activate a relay or other device when the program is complete.

To transfer the sample history to an external Sigma 950 flow meter, program complete must be
disabled. In addition, the special output must be enabled and configured to assert after the sample
cycle is complete.

1. Select PROGRAM SETUP>MODIFY SELECTED>ADV SAMPLING from the main menu.

2. Select PGM COMPLT O/P>ENABLE. The message “Bottle number output disabled on pin F” will

be shown. The bottle number output to send sample history to a Sigma 950 flow meter will be
disabled.

3. Select ENTER to activate the output signal.

30

English

Send output signal with sample cycle (special output)

The special output option sends a 12 VDC signal through pin E of the auxiliary connector during or
after a sample cycle.
There are five possible configurations:

• After cycle—4-second pulse at the end of each sample cycle. This option is used to signal an
external device that a sample cycle is complete.

• Entire cycle—during the entire sample cycle, includes all purge and rinse cycles.

• During sample—during the sample intake portion of the cycle only, ignores all purges and rinse
cycles.

• Missed sample—4-second pulse in the event of a missed sample. A missed sample can be
caused by a distributor error, purge fail, rinse fail, sample timeout, full bottle or pump fault.

• Trouble output—4-second pulse when a low main battery or low memory battery error occurs.

Two configurations are necessary to transfer sample history to an external flow meter:

• First, the program complete output needs to be disabled to enable the bottle number output. The
bottle number output transmits whether the sample was taken successfully or not and which bottle
received the sample.

• Second, the special output needs to be enabled and configured to assert "After Each Sample".
The sample history will be transferred to the external Sigma 950.

1. Select PROGRAM SETUP>MODIFY SELECTED>ADV SAMPLING from the main menu.

2. Select SPECIAL OUTPUT>ENABLE.

3. Select one of the output options:

• AFTER CYCLE—at the completion of each sample cycle

• ENTIRE CYCLE—during the entire sample cycle

• DURING SAMPLE—during the sample intake

• MISSED SAMPLE—in the event of a missed sample

• TROUBLE OUTPUT—when a low main battery or low memory battery error occurs

Operate from an external signal (setpoint sample)

The setpoint sample option starts and stops the sampler after a signal is received from an external
device such as a flow meter. The current program status shows when the sample program is
inhibited by an external device.

Note: Setpoint and stormwater sampling cannot be enabled at the same time.

1. Select PROGRAM SETUP>MODIFY SELECTED>ADV SAMPLING from the main menu.

2. Select SETPT SAMPLE>SETPT TRIGGER>EXT TRIGGER >ENABLE.

3. Select SETPT SAMPLE>SETPT CONTROL and select one of the setpoint options:

Option Description

START ON SETPT The sampling program operates until the program is complete.

START/STOP The sampling program operates until the external signal is no longer received.

4. To use a setpoint delay, enter a delay time in hours and/or minutes. The delay time starts when

the external signal is received. The program starts when the delay time expires.

Use an SDI-12 device for setpoint sampling

When an SDI-12 device is connected to the controller, the measurements can be used as setpoint
sampling triggers (in addition to the external inhibit). A maximum of one measurement trigger can be
enabled that is independent of the external trigger. If multiple triggers are enabled, the program starts
from at least one trigger and stops when all triggers are cleared.

English

31

Each trigger can be defined as a high or low setpoint. Additionally, an optional deadband value can
be set. A deadband prevents the trigger from rapidly changing between active and inactive states
when the measurement value is near the setpoint. Refer to Figure 15.

1. Go to PROGRAM SETUP>MODIFY SELECTED>ADV SAMPLING>SETPT SAMPLE>SETPT
TRIGGER.

2. Select a measurement channel.

Note: A check mark is shown when a channel is enabled as a trigger.

3. Enter a setpoint trigger within the range that is shown.

4. Enter an optional deadband value.

5. Select ENABLE.

6. Select SETPT CONTROL to define how the sample program will operate.

Option Description

START ON SETPT The sampling program operates until the program is complete.

START/STOP The sampling program operates until the trigger is cleared.

7. To use a setpoint delay, enter a delay time in hours and/or minutes. The delay time starts when

the setpoint trigger becomes active. The program starts when the delay time expires.

Note: Setpoint control and delay options are global settings that are applied to all triggers.

5. Enter the time (24-hour format) and date for the first stop time.

6. Continue to add start and stop times as necessary.

Collect first flush stormwater samples

The stormwater option collects first flush (FF) samples or initial runoff during storm conditions when
pollutants are typically at high concentrations. The first flush samples are collected at timed intervals
and can be started by an external device. A stormwater program can operate at the same time as the
main program. First flush samples are usually collected within 30 minutes of a storm. The stormwater
program has these capabilities:

• Collect grab samples at up to 24 different time intervals. First flush and main program flow­weighted composite samples are automatically segregated. The first flush sample volume may be
set independently of the sample volume for the flow-weighted composite.

• Initiation by an external device. A dry contact closure across pins B and D on the auxiliary
connector, held closed for at least 61 seconds, is necessary.

• For multiple bottles, the sampler can be programmed to collect one large “first flush” sample (or
small multiple samples) at timed interval(s). The number of bottles segregated for the first flush
sample is selectable. Concurrently, flow-weighted samples are collected from the beginning of the
storm until all remaining bottle(s) are filled, or after a specified time has elapsed.

Note: NPDES requirements typically requests that the first three hours of a storm be monitored. If the flow volume
is lower than expected, flow-weighted sampling can continue for a long time as the flow rates decrease and the
sample intervals become longer.

1. Go to PROGRAM SETUP>MODIFY SELECTED>ADV SAMPLING.

2. Select STORMWATER>ENABLE.

3. Select how the program will start.

Option Description

Immediate The user starts the sampling program.

External The sampling program starts when a signal is received by an external device.

4. If configured for a single bottle, enter the number of first flush (FF) samples to collect.

5. If configured for multiple bottles, enter the number of bottles to be used for first flush collection.

6. Enter the multi-bottle distribution mode.

• Samples per bottle—more than one sample is collected in each bottle

• Bottles per sample—more than one bottle is used to collect each sample.

7. Enter the number of samples per bottle or bottles per sample.

8. Enter the time interval between each first flush sample cycle. The intervals can be different. The

sum of the intervals is equal to the total length of the stormwater collection period.

Note: The number of intervals is determined by the number of bottles and the distribution mode.

9. Enter the volume of each first flush sample.

10. Select whether a time limit will be used.

Option Description

ENABLE The sampling program stops after a specified time. Enter the time.

DISABLE The sampling program operates until the program is complete.

Set variable intervals

Variable time intervals (hours and minutes) or flow intervals (counts) can be set for sample cycles.
Variable intervals cannot be enabled when CTVV is enabled.

English

33

1. Select PROGRAM SETUP>MODIFY SELECTED>ADV SAMPLING from the main menu.

2. Select VARIABLE INTVL>ENABLE.

3. Enter the time or count interval between each sample cycle and push ENTER to save the interval.

Up to 99 intervals can be entered.

Timed bottle sets

The timed bottle option makes a single sampler operate like multiple samplers. This option is useful
for situations such as high flow versus low flow days. The sampler is configured to start a sampling
program in multiple parts. The first part of the program starts for a user-specified time interval. The
second part then operates for a user-specified time interval, followed by the third part, etc.

The sample bottles are also divided into multiple sets. The first set of bottles is assigned to part one
of the sampling program. The second set of bottles is assigned to part two of the sampling program,
etc.

A timed bottle program can run at the same time as the storm program, setpoint sampling and
variable intervals.

When enabled with variable intervals, the timed bottle option will collect samples in each timed bottle
set based on the specified variable intervals. When a timed bottle set switch occurs upon expiration
of the trigger time, the variable interval index is reset.

Note: Timed bottle can be enabled only if the sampler is configured with multiple bottles, non-composite mode and
the distribution mode is set to Bottles/Sample.

1. Go to PROGRAM SETUP>MODIFY SELECTED>ADVANCED SAMPLING.

2. Select TIME BOTTLE>ENABLE.

3. Enter the number of samples to be collected in each timed bottle set.

4. Select one of the timed bottle trigger time methods.

Option Description

24 HR FORMAT The time that must expire every day before one bottle set switches to the next bottle set.

DURATION As long as the controller is not inhibited, the trigger timer starts when RUN is pushed and

START is selected.

The bottle set size is shown.

5. Select when the program will stop.

Option Description

CONTINUOUS The program must be stopped manually.

END AFTER LAST The program stops when the last sample is collected in the last bottle of the last timed

bottle set.

Note: If Take 1st Sample is set to IMMEDIATE on the controller, the first sample of every timed bottle set is
taken immediately. If Take 1st Sample is set to AFTER THE INTERVAL, the first sample of every timed bottle
set is taken after the first interval.
