2 Overview
Thank you for purchasing from Chemtrac, Inc.
The UVM5000 is a continuous UV 254nm organic testing monitor
which utilizes an innovative dual path measurement technique,
shown in the following illustration.
The UVM5000 is designed to take sensor readings at 90-
degree angles to each other through two different path lengths
through a rectangular quartz flow cell. The two sensor readings
give the amount of light able to pass through two different path
lengths of test water. From these two measurements alone, the
UV transmittance (UVT) or UV absorbance (UVA) of the test
water is calculated without continuous need for calibration.
By continuously taking readings in the two directions through
the flow cell, calibration is effectively performed every time a
sample is taken. Therefore, quartz fouling and lamp fluctuations
are inherently compensated for by the measurement process
itself, improving accuracy.

1. Position the flat side of the motor shaft so it is facing out as shown in Figure 5.1.
2. Place the rotating arm on the motor shaft as shown in Figure 5.2, pushing down as far as possible.
3. Tighten the shaft locking screw with a #2 Phillips screwdriver as shown in Figure 5.3.
5.3.2 Installing the Quartz Flow Cell
1. Remove the flow cell carefully from the packaging. The flow cell should be clean, and care should be
taken to prevent fingerprints, especially in the middle region of the flow cell where the light beam passes
through. (Wearing gloves is recommended.)
2. Insert the flow cell into position under the flow cell header as shown below in Figure 5.4. Align the black
dot on the flow cell with the black dot on top of the white plastic flow cell guide.
3. Carefully and slowly lower the clamp ensuring it is aligned with the flow cell as shown in Figure 5.5 and
Figure 5.6. The flow cell clamp should not require much force when clamping down. If any significant
force is required, try adjusting the position of the flow cell to prevent damage.

5.4 Mounting
The monitor should be attached to the wall at all four of the
mounting holes provided (top left and right; bottom left and
right in Figure 5.10). Use screws and washers that are
sturdy enough to support the cabinet weight of
approximately 20 lbs.
Cabinet dimensions are to the nearest 1/8 inch. Refer to
Section 18, Cabinet Dimensions and Clearance for
drawings of dimensions and clearance.
The expanded view at right
(Figure 5.11) shows an example
of a ¼” bolt and washer inserted
in the front side of the cabinet.
5.5 Plumbing
Process water from a pressurized pipe flows into the monitor via a ¼”
push to connect fitting. The sample is analyzed by the sensor inside
the cabinet and discharged to drain as shown in Figure 5.12.
IMPORTANT: If the UVM5000 was supplied with the Dual Feed or
Auto Clean option, be sure to review the manual(s) that were supplied
with those optional devices before plumbing the system.
A shut off valve must be installed to allow the flow to the monitor to be
shut off when servicing is required. A flow control valve is also
recommended to regulate the flow to 0.3 –1.0 L/min. A simple needle
valve is often used if pressure is somewhat consistent.

There are two push-in fittings on the side of the cabinet labeled IN and
OUT as shown in Figure 5.13.
1. Connect ¼” OD flex tubing from the process to the IN-push
connector on the monitor.
2. Connect another piece of ¼” tubing to the OUT port on the monitor
and divert the line to the drain.
IMPORTANT: The test water must be allowed to flow unrestricted to the
drain so that no significant water pressure occurs inside the analyzer.
The maximum pressure rating for the monitor is 20 PSI.

5.6 Turbidity and Filtration
Depending on the application, the role of turbidity can be
treated either as a part of the measurement, or as an
interference in the measurement.
For example, a UV disinfection application will generally
require a transmittance measurement that includes the
effects of both dissolved organics and light blocking
particulate, whereas an organics monitoring application will
often require a measurement of the organics isolated from
the light blocking effects of particulate.
Because of this, Chemtrac’s monitors can include an
optional 550 nm turbidity compensation measurement.
Since 550 nm light is not significantly sensitive to organic
material but is sensitive to light blocking particulate, the
550-nm turbidity compensation measurement can provide
an isolated measurement of turbidity that allows this
turbidity component to be extracted from the 254-nm
measurement. This results in a measurement of organics
material independent of turbidity and particulate in the
water. The same results can also be achieved by removing
light blocking particulate from the sample stream through
filtration.
5.6.1 Turbidity Compensation (Optional)
Optional turbidity compensation can be added to any
UV254 analyzer. Turbidity compensation allows for
sampling without filtration in water with turbidity levels
below ~60 NTU. Above 60 NTU, a 50-200-micron filter
should be installed prior to sampling. If 50-micron is not
sufficient to obtain 60 NTU on the filter effluent, a 20-micron
filter should then be added. Refer to menu item Turbidity
Comp. in Section 9, Menu Structure, to enable the turbidity
compensation feature.
5.6.2 Filtering
All UV254 analyzers without turbidity compensation can
obtain an accurate reading of dissolved organic matter at
a turbidity level below ~10 NTU. If the sample water has
turbidity levels that fluctuate above 10 NTU, a 50-micron
filter should be installed prior to sampling. Should 50-
micron not be sufficient to obtain 10 NTU on the filter
effluent, a 20-micron filter should then be added.

5.7 Electrical Connections
The 24 VDC power is supplied to the UVM5000 by means
of a DC power adapter that is plugged into a wall outlet of
100-240 VAC 50/60 Hz. The two 24 VDC wires from the
adapter are run through the connector in the bottom of the
monitor. The black wire is connected to terminal #11 (-)
and the red wire (+) is connected to terminal #12, as
shown in Figure 5.14.
Both 24 VDC power and communication lines feed into the
monitor via one ¾” electrical conduit fitting on the bottom
of the monitor and must be connected to the terminal block
on the main control board.
5.8 4-20 Ma Connections and Dry Contacts
Primary communication is provided by a 4-20mA
sourcing current loop output. RS-232 is also included to
allow direct connection to a PC COM port if desired. A
configurable digital output / dry contact is also
available. These provide the operator with alarms for
operator configured UVT/UVA set-points and system
failure alarms. Dry contact connections are from
terminals #5 & #6. The 4-20 mA output connections are
from negative terminal #3 and positive terminal #4.
Dual Feed Connection –For the dual feed option, a
second pair of 4-20 mA output connections are from
negative terminal #1 and positive terminal #2. This
output signal is for the water stream 2.
Automatic Chemical Clean Connection - Power to
the optional Automatic chemical clean system is
provided at connector terminals #9 and #10, which run
to the left terminal block on the circuit board in the
chemical clean cabinet. Matching the correct polarity is
important. The chemical clean logic is through
connector terminals #7 & #8, which run to the right terminal
block on the circuit board in the chemical clean cabinet.
Polarity is not important.

6 Start-up
After the monitor has been installed as described in the Installation section, operation of the monitor is very
straight-forward.
6.1 Start-up Instructions
1. Inspect the inside of the monitor to ensure all packing material (which may restrict moving parts inside
the monitor) has been removed.
2. Ensure the 24 VDC power wires are securely attached to the correct corresponding terminals. Do not
plug the monitor in at this time.
3. After making sure the flow rate has been set to 0.3 –1.0 L/min and the drain is unrestricted and not
kinked, open the inlet valve to allow test water to flow through the monitor and check for any leaks in the
flow cell, piping, and fittings for at least 10 minutes before proceeding to the next step. Ensure there are
no bubbles flowing through the flow cell and no water droplets are on the inside of the monitor.
4. Plug in the power supply. Display screen will read “Initializing.”
5. Calibrate your Analyzer. Measurements are not assumed to be accurate until the analyzer is calibrated.
See Section 8, Zeroing (Calibration).
6. Configure the monitor to your application, i.e. enter warning and alarm set points, dry contact, 4-20mA
set-up, data logging. See Section 9, Menu Structure.
IMPORTANT: In areas of high humidity, the UVM5000 door must remain closed for a minimum of three
hours to allow for the dehumidifier to dry the air inside the enclosure. (Refer to Section 13). If you
receive a Humidity alarm while calibrating, the door may not have been closed long enough. Wait until
the alarm is removed, and then start calibration again.

8 Calibration (Zeroing)
The monitor must be calibrated before accurate UVT/ UVA data can be read. Two methods for calibration can
be used:
•Zero monitor to DI or RO water reference of 100% UVT
•Zero monitor to a known water value
The first method is using 100% transparency as the standard by which the monitor is zeroed, whereas the
second method uses a known transparency. Both are accurate, but the second method allows for greater
accuracy because the expected measured values are presumably clustered around the known value instead of
falling within a wider range in the measurement scale.
8.1 Using RO or DI Water Method
Carry out these steps using a fresh supply of DI or RO water:
1. Close the monitor door and secure both door clamps.
2. Make sure the monitor is powered up.
3. Shut off the water supply to the monitor if not already
done.
4. Disconnect the ¼” supply tubing at the inlet connection
on the monitor.
5. Fill the supplied wash bottle with DI/RO water and
connect the ¼” bottle tubing to the inlet connection on
the monitor.
6. Hold a finger over the small vent hole in the wash
bottle cap, as shown in Figure 8.1.
7. Squeeze the bottle to get the DI water to flow through
the monitor.
8. Once the fluid starts to flow remove finger from the
vent hole and place bottle on top of the monitor, as
shown in Figure 8.2. The fluid should continue to flow
through the monitor. If it stops go back to step 6.
9. The LCD display should display a UVT or UVA reading
(depending on display mode).
10. Let about half the DI water run through the monitor
before pressing the Zero button. Use the down arrow
to select “Zero to DI Water”. Then press “Enter” and
the monitor will calibrate itself to 100% in UVT mode
or 0.000 in UVA mode.
11. The monitor has now been calibrated to DI/RO water.
Disconnect the wash bottle hose from the inlet of the
monitor.
12. Connect the supply line to the monitor and open the
valve to start the flow running.

8.2 Using Known Water Method
Carry out these steps:
1. Press the Zero button on the monitor. The Calibration menu appears.
2. Scroll down to ‘Custom Zero’ using the down arrow button. Press Enter.
3. A default value is displayed in the ‘New UVT:’ field (in this example, 75.0).
4. Press the up arrow to increase the number above 75.0 or the down arrow to decrease the number
below 75.0. When you have keyed in the number of known water transparency, press Enter.
Note that if you only know your UVA value then this can be converted to UVT using the formula:
UVT = 100 * 10(-UVA)
5. The monitor is now calibrated to the correct value.
