2.2 General Product Information
The controller enclosure is NEMA4X/IP66-rated and has a corrosion-resistant
finish designed to withstand corrosive environmental constituents such as salt
spray and hydrogen sulfide. The controller display shows the current turbidity
reading if connected to a single sensor, or two readings when two sensors
are connected.
The 1720E Turbidimeter is a continuous-reading nephelometric turbidimeter
designed for low-range turbidity monitoring. This process turbidimeter is capable
of measuring turbidity from 0.001 to 100.0 NTU. Calibration is based on formazin,
the primary turbidity reference standard adopted by the APHA Standard Methods
for the Examination of Water and Wastewater and the U.S. Environmental
Protection Agency (EPA) and on StablCal® which is also recognized as a primary
standard.
6
General Information
2.3 Theory of Operation
The 1720E Turbidimeter measures turbidity by directing a strong beam of
collimated light from the sensor head assembly down into the sample in the
turbidimeter body. Light scattered at 90° relative to the center line of incident light
by suspended particles in the sample is detected by the submerged photocell
(see Figure 1).
Figure 1
90 Degree Detector
The amount of light scattered is proportional to the turbidity of the sample. If the
turbidity of the sample is negligible, little light will be scattered and detected by the
photocell and the turbidity reading will be low. High turbidity, on the other hand, will
cause a high level of light scattering and result in a high reading.
Sample enters the turbidimeter body and flows through the baffle network of the
bubble trap. The flow allows bubbles to either cling to surfaces of the baffle system
or rise to the surface and vent to atmosphere. After traveling through the bubble
trap, sample enters the center column of the turbidimeter body, rises into the
measuring chamber and spills over the weir into the drain port. A reading is taken
once per second.

3.2.3 Wiring for Power at the Controller
Wire the instrument for line power by hard-wiring in conduit or by wiring to a power
cord if local code allows. Regardless of the type of wire used, the connections are
made at the same terminal. A local disconnect designed to meet local electrical
code is required and must be identified for all types of installation. See Figure 16
and Figure 17 on page 17 for suggested local disconnect configurations.
1. Obtain appropriate fittings with NEMA 4X/IP66 environmental rating.
2. Loosen the screws using a phillips-head screwdriver and open the hinged
controller cover.
3. Remove the high-voltage barrier (see Figure 12 on page 14).
4. Insert the wires through the strain relief fitting or conduit hub located in the
right-rear access hole in the bottom of the enclosure. Tighten the strain relief if
used, to secure the cord.
5. Properly prepare each wire (Figure 14) and insert each wire into the terminal
according to Table 4. Tug gently after each insertion to ensure the connection
is secure.

3.3
Alarms and Relays
The controller is equipped with three unpowered relays rated 100–230 V ac,
50/60 Hz, 5 amp resistive maximum.
3.3.1 Connecting the Relays
The relay connector accepts 18–12 AWG wire (as determined by load
application). Wire gauge less than 18 AWG is not recommended.
Danger: Relay loads must be
resistive. User must externally
limit current to the relays to
5 Amps by use of a fuse or
breaker.
The controller contains three relays designed for use with high voltage
(greater than 30V-RMS and 42.2V-PEAK or 60 V dc). Refer to Figure 18 for
connection information. The wiring is not designed for low voltage connections.
Relay must not be powered from the same wiring used to power the controller.
See section 4.6 on page 34 for relay setup details.
Danger: ac power terminals are
designed for single wires. Do not
use more than one wire in each
terminal.
The Normally Open (NO) and Common (COM) relay contacts will be connected
when an alarm or other condition is active. The Normally Closed (NC) and
Common relay contacts will be connected when an alarm or other condition
is inactive or when power is removed from the controller.

Connecting the Analog Outputs
Two isolated analog outputs (1 and 2) are provided, see Figure 19. Each output
can be set to 0–20 or 4–20 mA, and can be assigned to represent the measured
parameter or secondary measurement such as temperature. Make connections
with twisted-pair shielded wire and connect the shield at the controlled component
end or at the control loop end. Do not connect the shield at both ends of the cable.
Use of non-shielded cable may result in radio frequency emission or susceptibility
levels higher than allowed. Maximum loop resistance is 500 ohm. Refer to
section 4.5 on page 32 for output software setup.

3.6 Turbidimeter Installation Information
The turbidimeter body is designed for wall-mounting (although it may be mounted
on the optional floor stand). The turbidimeter sensor must be mounted within
six feet of the controller unless an extension cable is used. Maximum cable length
is 9.6 m (31 feet).
3.6.1 Mounting the Turbidimeter Body
Locate the turbidimeter as close to the sampling point as possible. A shorter
distance for the sample to travel results in a faster response time.
Clean the turbidimeter body and bubble trap before installation using the
instructions supplied in section 6.4.3, Cleaning the Turbidimeter Body and Bubble
Trap on page 48. Slotted mounting brackets are integral parts of the turbidimeter
body. Install customer-supplied hardware appropriate for the installation
environment using the criteria detailed below:
Note: Make sure the top of the
turbidimeter body is level.
•
Install in a location that is isolated from vibration.
•
Allow at least 22 cm (approximately 10 inches) clearance for removal of the
head assembly and bubble trap cover from the top of the turbidimeter body.
•
Leave enough room below the turbidimeter body to remove the bottom plug
and to place a container under the drain when calibrating or cleaning.
•
Install two ¼-20 bolts 10-3/4 inches apart (on center). Leave at least ¼-inch of
the bolt head exposed.
•
Make sure the bolts are installed level.
Slide the slotted mounting brackets of the turbidimeter body onto the bolts.
3.6.2 Installing the Head Assembly
After the turbidimeter body has been mounted, install the bubble trap cover, then
place the head assembly on the turbidimeter body with the label facing the front.
Move the head assembly back and forth slightly to ensure it is properly seated on
the body of the instrument. Failure to properly seat the head will result in light
leakage and erroneous readings.
The rear portion of the head assembly has a molded “lip” which may be used to
hang the head assembly on the turbidimeter body edge for routine maintenance.
3.7 Installing a Sample Line
DANGER
This turbidimeter is not designed
for use in hazardous locations or
with samples that are flammable
or explosive in nature. If any
sample solution other than water
is used in this product, test the
sample/product compatibility to
ensure user safety and proper
product performance.
24
One-fourth inch O.D. rigid or semi-rigid tubing is recommended for sample lines.
Run them as directly as possible between the turbidimeter body and the sampling
point to minimize sample flow lag time.
Install sample line taps into larger process pipes to minimize interference from
air bubbles or pipeline bottom sediment. A tap projecting into the center of the
pipe is ideal. Figure 24 shows examples of sample tap installations.
Note: When setting the flow rate, take care to avoid sweeping air “micro-bubbles” through
the internal bubble trap. Observe the sample flow inside the turbidimeter body. If small
air bubbles can be seen flowing up through the center, reduce the flow rate.
Installation
Figure 24

Air (Typical)
Sediment (Typical)

3.8 Sample Connections
Sample inlet and drain connections are made on the turbidimeter body. The
sample inlet fitting installed in the body is a ¼-inch NPT x ¼-inch compression
fitting. One additional fitting supplied with the instrument is a ½-inch NPT-to-hose
fitting for use with ½-inch ID flexible plastic tubing on the drain.
Note: For samples with high solids
content (high turbidity), operate at
the highest flow rate possible. For
samples with low solids content (low
expected turbidity), operate at a low
flow rate (200–300 mL/min).
Figure 25
The required flow rate is 200 to 750 mL/minute (4.0 to 11.9 gal/hour). Flow rate
into the turbidimeter may be controlled with a flow restriction device on the inlet
line. Flow rates below 200 mL/min will reduce response time and cause
inaccurate readings. Flow rates above 750 mL/min will cause the turbidimeter to
overflow, indicating the flow rate is too high.

Operation
4.7 Data and Event Logging Options
The sc100 provides two data logs (one for each sensor) and two event logs (one
for each sensor). The data logs store the measurement data at selected intervals.
The event log stores a variety of events that occur on the devices such as
configuration changes, alarms, and warning conditions. The data logs are stored
in a packed binary format and the event logs are stored in a CSV format. The logs
can be downloaded through either the digital network port or the IrDA port using
the file transfer program available from the manufacturer.
The default datalogging frequency is 15 minutes. If the datalogging frequency is
set to 15 minute intervals, the instrument can continue to store data for
approximately six months.

5.1 General Operation
Plug the sensor into the unpowered controller by aligning the orientation tab on
the cable connector with the channel in the controller connector. Push in and turn
to secure the connection. Tug gently to check the connection.
After all plumbing and electrical connections have been completed and checked,
place the head on the body and supply power to the system. Ensure the head is
seated on the body when power is applied, since dark readings are measured at
this time. If power is applied while the sensor head is off the turbidimeter body,
cycle the power with the sensor head on the body.
The first time a controller is powered up, a language selection menu will appear.
The user must select the correct language from the displayed options.
Use the UP and DOWN keys to highlight the appropriate language and press
ENTER to select.
Following language selection and upon power-up, the controller will search for
connected sensors. The display will show the main measurement screen. Press
the MENU key to access the menus.
5.2 Starting Sample Flow
Start sample flow through the instrument by opening the sample supply valve.
Allow the turbidimeter to run long enough for the tubing and body to become
completely wetted and the reading on the display to stabilize. One to two hours or
longer may be required initially for complete stabilization. Allow measurements to
become stable through adequate conditioning before completing instrument
settings or performing calibrations.
5.3 Sensor Calibration and Verification
The manufacturer offers two EPA-approved calibration methods one using userprepared formazin and the other using StablCal® stabilized formazin. Two
verification methods (wet and dry) are also offered.
The 1720E Turbidimeter is factory-calibrated using StablCal® Stabilized Formazin
before shipment. The instrument must be recalibrated before use to meet
published accuracy specifications. In addition, recalibration is recommended after
any significant maintenance or repair and at least once every three months during
normal operation. The turbidimeter body and bubble trap must be thoroughly
cleaned and rinsed before initial use and prior to each calibration.
Tips to achieve the most accurate calibrations:
40
•
Optimum performance is achieved when calibration is performed in the
turbidimeter body. Accurately prepare the standard then add it to the
turbidimeter body at the appropriate step in the procedure. Do not prepare the
standard in the body.
•
Stop sample flow, drain, and clean the turbidimeter body before beginning the
calibration procedure.
•
Always clean the photocell window per the instructions in section 6.4.2 on
page 48. Rinse the photocell with deionized water and dry with a soft, lint-free
cloth before calibrating.
System Startup
•
Always clean the turbidimeter body or calibration cylinder per the instructions
in section 6.4.3 on page 48. Rinse with deionized water before calibrating.
•
Store the calibration cylinder upside-down to minimize contamination between
calibrations.
•
Pour the calibration standard into the turbidimeter body at the inflow end (left
side when facing the instrument).
•
Gently invert StablCal standards for 1 minute before opening. Do not shake.
This ensures a consistent turbidity of the standard.
•
If the 20.0 NTU StablCal standard is allowed to sit in the calibration cylinder or
turbidimeter body for more than 15 minutes, it must be remixed (gently swirled
in the calibration cylinder) before use to ensure a consistent turbidity.
•
Discard all standards after use per the instructions on the container.
Never transfer the standard back into its original container. Contamination
will result.
•
Always recalibrate after restoring default settings.
5.3.1 User-prepared Calibration
Before starting the calibration, read and apply the tips in section 5.3.
Follow the procedure as written (using 1 L of deionized water and 5.0 mL of
4000 NTU formazin) if using a calibration cylinder for calibration.
If using the turbidimeter body for the user-prepared calibration follow the
procedure below using 20 NTU formazin in step 6c. Prepare the standard as
follows:
1. Stop the sample flow, then drain and clean the body.
2. Prepare a 20 NTU standard by adding 5.0 mL of 4000 NTU formazin to a
1-L flask. Dilute to the mark with deionized water and invert gently to mix.
3. Drain the deionized water and pour the prepared 20 NTU standard into the
turbidimeter body at step 6c. Do not add additional 4000 NTU formazin.

5.4 Instrument Verification
Instrument verification is intended as a simple check to ensure turbidimeter
functionality between calibrations. A verification is initially performed directly after
a calibration and subsequent independent verifications are referenced to the initial
verification. The pass/fail criteria is set and subsequent verifications are deemed
good or bad, when compared to the initial verification. All verifications are based
on the current calibration and must be repeated when the instrument is
recalibrated or when the pass/fail criteria is not met.
43
System Startup
Two types of verifications are offered. The dry verification is performed using a
“dry” calibration device such as the ICEPIC™. A wet verification is performed
using a standard with a predetermined value such as StablCal® Stabilized
Formazin or a user-prepared standard with a value that has been verified on an
independent device such as a laboratory turbidimeter.

5.5 Calibration and Verification History
The calibration and verification history logs contain information on the last
12 calibrations and the last 12 verifications. The calibration history log shows the
gain value, the time and date of the calibration, and the initials of the operator
performing verification.
Note: Restoring default settings
from the DIAG/TEST menu will
return the turbidimeter to its non
calibration state (gain = 1.0) but it
will not remove the previous
calibration history from memory.
The calibration history log is accessed from the Calibrate menu. The verification
history log is accessed from the Verification menu (a submenu of the Calibrate
menu).
Each verification history entry shows the serial number of the verification device
(dry verification) or the value of the verification standard (wet verification), the time
and date of the verification, and the initials of the operator performing the
verification.
Scroll through the entries by pressing the ENTER key. After scrolling through all
12 histories, the display will return to the calibration menu level.
When the instrument is received from the factory, default values or blank spaces
will be shown for the calibration and verification history information. Those values
will be replaced with real data as the history log is filled.
The data is retained as first in, first out. When the log is full, the newest entry is
stored and the oldest entry in the log is deleted.

Section 6
Maintenance
DANGER
Only qualified personnel should conduct the maintenance tasks described
in this section of the manual.
6.1 Maintenance Schedule
Maintenance Task
Frequency
Clean the sensor
Before each calibration and as needed. Depends on sample
characteristics.
Calibrate Sensor (as required by regulatory agency)
Per agency-dictated schedule.
Scheduled periodic maintenance requirements of the 1720E are minimal and
include calibration and cleaning of the photocell window, bubble trap, and body.
Check and clean the bubble trap and turbidimeter body (as described in
section 6.4.3) if visual inspection shows that it is necessary. Perform other
maintenance on a regular basis; experience will dictate scheduling and may
depend on the installation, sample type, and season.
It is very important to maintain the cleanliness of the interior and exterior of the
turbidimeter body, head assembly, the integral bubble trap, and the surrounding
area. Doing so will ensure accurate, low-level turbidity measurements.
Clean the body before calibration and verification (especially when measurements
are being made at 1.0 NTU or lower).
Check and/or perform a calibration periodically (as experience dictates) using one
of the methods described in section 5.3 on page 40. A calibration history menu
option is available under Sensor Setup/Calibrate.
6.2 Removing a Sensor from the System
Prior to physically removing a sensor from the system, record all user defined
settings such as relays, signal averaging, etc. Disconnect the sensor connector at
the controller.
6.3 Reinstalling a Sensor on the System
To return the system to normal operation following a software upgrade or sensor
repair perform the following procedure:
1. Detach all sensors from the sc100 controller.
2. From the main menu, press the down arrow key to highlight TEST/MAINT.
Press ENTER.
3. Use the down arrow key to scroll to SCAN SENSORS and press ENTER.
4. Remove attached sensors by selecting the corresponding serial number or
select “All”.
5. Power down the sc100 then attach the 1720E.
Note: Clean sensors before
reinstallation on the system.
6. Supply power to the sc100. The system will initialize automatically.
47
Maintenance
6.4 Cleaning
6.4.1 Cleaning the Controller
With the enclosure securely closed, wipe the exterior with a damp cloth.
6.4.2 Cleaning the Photocell Window
Occasional cleaning of the photocell window is required. The frequency will
depend on the nature and concentration of dissolved and suspended solids in the
sample. Biological activity is a primary factor in mineral scale deposit on the
window and the amount differs with sample temperature. In general, more growth
will occur in warm temperatures and less in cold.
Note: Take care to not scratch the
photocell window.
Inspect the photocell window often to determine cleaning needs. Remove any
organic growth or film on the photocell window before standardization or
calibration. Use a cotton swab and isopropyl alcohol or a mild detergent (such as
Liqui-nox®) to remove most sediment and dirt. Mineral scale buildup may require
cleaning with a mild acid applied with a cotton swab followed by a detergent wash.
Do not use abrasive cleaners.
6.4.3 Cleaning the Turbidimeter Body and Bubble Trap
Sediment may collect in the turbidimeter body after extended use. Noise
(fluctuation) in the reading could indicate the need to clean the body and/or bubble
trap. The 1720E bubble trap and bottom plate may be removed to make cleaning
easier. Drain and clean the turbidimeter body before each calibration. Establish a
regular schedule or perform cleaning as determined by visual inspection.
Cleaning the Turbidimeter Body
Note: The turbidimeter body, bubble
trap, and detector must be cleaned
before each calibration.
1. Turn off sample flow to the turbidimeter body.
2. Remove the head assembly and bubble trap cover from the body. Remove the
bubble trap by lifting it vertically. Set it aside to be cleaned separately.
3. Drain the body by removing the plug from the bottom of the body.
4. Replace the drain plug and fill the body to the weir with cleaning solution. This
cleaning solution can consist of dilute chlorine solution (25 mL of household
bleach in 3.78 liters of water) or a laboratory detergent such as Liqui-nox
(1 mL detergent in 1 liter of water).
5. Use a soft brush to clean the inside surfaces of the body.
6. Remove the drain plug again and thoroughly flush the turbidimeter body with
ultra-filtered deionized water. Clean and replace the plug.
Cleaning the Bubble Trap
1. Prepare a cleaning solution (as in step 4 above) in a container large enough
to submerge the entire bubble trap.
2. Using a test tube brush such as Cat. No. 690-00, clean each surface.
3. Rinse the bubble trap thoroughly with ultra-filtered deionized water and
reinstall it in the turbidimeter body.
4. Replace the bubble trap cover and head assembly on the top of the body.
48
Maintenance
5. Restore sample flow to the instrument.
6. Calibrate the instrument using one of the methods in section 5.3 on page 40.
If the above cleaning procedures have been performed and the turbidimeter
readings are still noisy, the bottom plate and gasket may need to be removed and
cleaned. Carefully perform the following procedure to ensure the turbidimeter
body integrity is maintained.
1. Turn off sample flow to the turbidimeter body.
2. Remove the head assembly, bubble trap cover, and bubble trap (by lifting it
vertically) from the body.
3. Drain the body by removing the plug from the bottom of the body.
4. Lift the body off of its mounting screws.
5. With the body turned upside-down, remove the two Phillips-head screws
holding the bottom plate.
6. Lift the bottom plate off the body; set the gasket aside for use in reassembly.
7. Use a soft brush and a dilute cleaning solution (as prepared above) to clean
the bottom plate and inside surfaces of the turbidimeter body. Rinse the entire
body and bottom plate with ultra-filtered deionized water.
8. Reassemble by inserting the gasket into the molded channel in the
bottom plate.
9. Fit the bottom plate onto the turbidimeter body.
10. Reinstall both screws and carefully tighten to 15 inch-lb maximum.
11. Reinstall the turbidimeter onto the wall mounting screws.
12. Replace the bubble trap, bubble trap cover, and head assembly on the top of
the body.
13. Restore sample flow to the instrument.
6.4.4 Replacing the Lamp Assembly
The Lamp Assembly is located on the head assembly. Under normal use, Hach
recommends replacing the lamp once a year to maintain peak performance.
Replacement bulbs have been “burned-in” at the factory and are ready for
installation and use.
To change the lamp, refer to Figure 28 on page 50 and perform the
following steps:
1. Disconnect power to the controller to remove all power to the turbidimeter.
2. Disconnect the lamp leads by unplugging the connector.
3. After the bulb has cooled, remove as follows:
49
Maintenance
a. Wear cotton gloves to protect your hands and to avoid fingerprints on
the bulb.
b. Grasp the bulb.
c. Twist the bulb in a counterclockwise direction, pulling out slightly, until it is
released from the housing.
d. Pull the lamp leads and connector through the hole in the lamp housing.
Do not touch the new bulb with bare hands. Etched glass and reduced lamp life
will result. Wear cotton gloves or grasp the lamp assembly with a tissue to avoid
contamination. If contamination occurs, clean the glass bulb portion with isopropyl
alcohol.
Replace the bulb by reversing the above instructions. The bulb base only fits one
way; align the notch in the metal bulb flange with the hole in the lamp holder.

Fuse Replacement
The controller contains two mains fuses. Failed fuses are an indication that an
equipment problem could exist. Problem resolution and fuse replacement should
only be performed by qualified service personnel. Refer to Figure 29 and perform
the following steps to replace the fuses:
1. Disconnect power to the controller (including power to relays if powered).
2. Open the hinged controller cover by completely loosening all four captive
screws in the cover.
3. Remove the high voltage barrier; pull out on the lever of the captive fastener
then pull straight out on the barrier. Set the barrier aside for reinstallation.
4. Remove the fuses and install new fuses of the same type and rating
(T, 1.6A, 250 V, slow blow).
5. Reinstall the high voltage barrier.
6. Close the controller cover and hand-tighten the four screws.
7. Reconnect all power to the instrument.
