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
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.

• CANCEL—Stay in the halted state
If RESUME is selected, the display shows a BOTTLES EMPTIED? message. Select YES or NO:
• YES—The controller starts to monitor the sample collection again.
Note: The controller acts as if the bottles are now empty even if they are not.
• NO—The program does not resume sample collection but stays in the HALTED state if the bottle
full condition was detected earlier.
Full bottle shutoff and timed bottle mode
In order to use the full bottle shutoff when timed bottle is enabled, the timed bottle run mode must be
set to END AFTER LAST.
If an attempt is made to run timed bottle in continuous mode, a NOT ALLOWED error screen shows
TB CONTINUOUS NOT POSSIBLE WITH FULL BTL.
If this error occurs, push ENTER to acknowledge the message. In the TB MODE screen that shows,
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
Page 33
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.

START/STOPThe 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.
English31
Page 34
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.

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.

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.

components.
W A R N I N G
Multiple hazards. The technician must make sure that the equipment operates safely and correctly
after maintenance procedures.
Clean the instrument
C A U T I O N
Fire hazard. Do not use flammable agents to clean the instrument.
N O T I C E
Do not clean the controller compartment heater with liquids of any kind.
If water is not sufficient to clean the controller and the pump, disconnect the controller and move the
controller away from the sampler. Allow sufficient time for the controller and pump to dry before the
parts are re-installed and put back into service.
Clean the sampler as follows:
• Sampler enclosure—Clean the internal and external surfaces with a damp cloth and a mild
detergent. Do not use abrasive cleaners or solvents.
•
Sample bottles—Clean the bottles with a brush and water and a mild detergent. Rinse with fresh
water and then with distilled water. Use an autoclave to clean glass bottles if necessary.
Replace the desiccant
A desiccant cartridge in the controller absorbs moisture and prevents corrosion. Monitor the
desiccant color through the window (Figure 16). Fresh desiccant is yellow. When the color is green,
replace the desiccant.
1. Unscrew and remove the desiccant cartridge (Figure 16).
2. Remove the plug and discard the spent desiccant.
3. Fill the desiccant tube with fresh desiccant.
4. Install the plug.
5. Apply grease to the O-ring.
6. Install the desiccant tube in the controller.

Pump maintenance
C A U T I O N
Pinch hazard. Remove power from the instrument before maintenance or service activities are done.
Replace the pump tubing
N O T I C E
Use of tubing other than that supplied by the manufacturer can cause excessive wear on mechanical parts and/or
poor pump performance.
Examine the pump tubing for wear where the rollers rub against the tubing. Replace the tubing when
the reminder message is shown or when the tubing shows signs of wear.
Pre-requisites:
• Pump tubing—pre-cut or bulk 4.6 m or 15.2 m (15 ft or 50 ft)
1. Disconnect the power to the controller.
2. If the bulk tubing is used, cut the tubing and add alignment dots.
3. Remove the pump tubing as shown in the illustrated steps that follow.
4. Clean the silicone residue from the interior of the pump housing and from the rollers.
5. Install the new pump tubing as shown in the illustrated steps that follow.

Replace the distributor arm tube
The distributor arm moves over each bottle during multiple bottle sampling. Replace the tube in the
distributor arm when the tube is worn. Make sure that the correct tube is used for the correct
distributor and distributor arm.
Note: The distributor tubing is not the same as the pump tubing. The pump tubing installed in the distributor
assembly can damage the distributor. Also, samples can be missed because the distributor arm cannot move
easily.
1. Remove the tube from the distributor arm and from the ceiling of the center section
.
2. Insert the new tube into the distributor arm. Make sure that the tube is aligned with the
dimensions shown in Figure 18.
3. Insert the other end of the tube into the fitting on the ceiling of the center section.
4. Complete the diagnostic test for the distributor to make sure that the operation is correct.
