In some cases, the sensor can be used in samples having pH as great as 10.0. Consult the factory.
1.1 APPLICATIONS
The FCL free chlorine system is intended for the determination of free chlorine in fresh water. Unlike free
chlorine transmitters from other manufacturers, the
FCL does not use expensive sample conditioning
systems or messy reagents to control pH. Instead, the
transmitter automatically compensates for changes in
the pH of the sample. The FCL is not intended for the
determi- nation of total chlorine or combined
chlorine (like monochloramine). Nor, can the FCL be
used for the determination of chlorine in seawater.
1.2 FEATURES
The FCL uses a membrane-covered amperometric
sensor. A polarizing voltage applied to a platinum
cathode behind the membrane reduces the chlorine
diffusing through the membrane and keeps the concentration of chlorine in the sensor equal to zero. The
current generated by the cathode reaction is proportional to the rate of diffusion of chlorine through the
membrane. Because the concentration of chlorine in
the sensor is zero, th e diffusion rate and the current
are proportional to the concentration of chlorine in the
sample.
All amperometric free chlorine sensors respond to
changes in pH. Although free chlorine is a mixture of
hypochlorous acid and hypochlorite ion, hypochlorous
acid alone is responsible for the sensor current.
Because the relative amounts of hypochlorous acid
and hypochlorite ion depend on pH, a pH change will
cause the current and the apparent free chlorine
concentration to change, even though the true concentration remained constant. Most manufacturers
solve the pH-dependence problem by treating the
sample with acid, which lowers the pH and converts
hypochlorite ion into hypochlorous acid. The FCL
avoids the expense and inconvenience of sample conditioning by measuring the pH and applying a correction to the raw chlorine sensor signal. The correction
is valid between pH 6.0 and 9.5. For samples having
pH between 9.5 and 10.0, consult the factory.
The FCL is available in two options: Model FCL-01
with manual pH correction and Model FCL-02 with
continuous pH correction. Choose the FCL-01 if the
pH varies less than 0. 2 or if pH changes are
predictable or seasonal. Choose the FCL-02 if the pH
varies more than 0.2. To provide the continuous
pH correction, the Model FCL-02 requires a separate
pH sensor.
Maintenance is fast and easy. Replacing a membrane
requires no special tools or fixtures. A screw cap holds
the pre-tensioned membrane in place. Replacing the
electrolyte solution takes only minutes.
The FCL includes the easy-to-use 56 transmitter.
The transmitter features four fully programmable 4-20
mA out- puts and four fully programmable relays. The
large, full color display allows the user to read sample
pH and chlorine concentration at a
glance. A data logger, graphical display, and
HART digital communications are standard.
Valves, rotameters, and pressure regulators to control
sample flow are things of the past with the FCL. A constant head overflow sampler ensures the correct sample flow to each sensor. To eliminate wiring hassles,
quick-disconnect Variopol cable is standard.
Stable free chlorine standards do not exist. The chlorine
sensor must be calibrated using the results of a laboratory test run on a grab sample.

temperature.
CAUTION
The FCL free chlorine transmitter is NOT suitabl e
for use in hazardous areas.
2. To keep the transmitter enclosure watertight, install plugs (provided) in the unused cable
openings.
3. Install the system in an area where vibrations and electromagnetic and radio frequency interference are minimized or absent.
4. Be sure there is easy access to the transmitter and
sensors.
2.2.2 Sample Requirements
Be sure the sample meets the following requirements:
1. Temperature: 32 to 122ºF (0 to 50ºC)
2. Pressure: 3 to 65 psig (122 to 549 kPa abs)
3. Minimum flow: 3 gal/hr (11 L/hr)
2.2.3 Mounting, Inlet, and Drain Connections
The Model FCL is intended for wall mounting only. Refer to Figure 2-1 or 2-2 for details. The sensor(s) screw into
the flow cell adapters as shown in the figures. For Model FCL-02 (free chlorine with continuous pH adjustment),
the pH sensor must be installed as shown in Figure 2-2.
A 1/4-inch OD tubing compression fitting is provided for the sample inlet. If desired, the compression fitting can
be removed and replaced with a barbed fitting. The fitting screws into a 1/4-inch FNPT check valve. The check
valve prevents the flow cells from going dry if sample flow is lost.
The sample drains through a 3/4-inch barbed fitting. Attach a piece of soft tubing to the fitting and allow the waste
to drain open atmosphere. Do not restrict the drain line.
Adjust the sample flow until the water level is even with the central overflow tube and excess water is flowing down
the tube.

Refer to Section 3.1 for details.
2.2.5 Installing the Sensor(s)
The Model FCL is provided with sensor cables pre-wired to the transmitter. Connect the chlorine sensor
(Model
499ACL-01-54-VP) to the cable labeled Chlorine. Connect the pH sensor (Model 3900VP-02-10 or older Model
399VP-09) to the cable labeled pH. The terminal end of the sensor is keyed to ensure proper mating with the cable
receptacle. Once the key has slid into the mating slot, tighten the connection by turning the knurled ring clockwise.
The sensor(s) screw into the plastic fitting(s), which are held in the flow cell(s) by the union nut. Do not remove the
protective cap on the sensor(s) until ready to put the sensor(s) in service.

RISK OF ELECTRICAL SHOCK
Electrical installation must be in accordance with
the National Electrical Code (ANSI/NFPA-70)
and/or any other applicable national or local codes.
3.1.1 Power
Wire AC mains power to the power supply board, which is mounted on the left hand side of the enclosure beneath
the gray plastic cover. To remove the cover, grab it by the upper edges and pull straight out. The power connector
is at the bottom of the board. See Figure 3-2. Bring the power cable through the conduit opening just below the connector. Unplug the connector from the board and wire the power cable to it. Lead connections are marked on the
connector. (L is live or hot; N is neutral; the ground connection has the standard symbol.)
Replace the cover. The two tabs on the back edge of the cover fit into slots at the rear of the enclosure, and the
three small slots in the front of the cover snap into the three tabs next to the relay terminal strip. See Figure 3-2.
Once the tabs are lined up, push
the cover to snap it in place.
AC power wiring should be 14
gauge or greater. Run the power
wiring through the conduit opening
nearest the power terminal.
Provide a switch or breaker to
disconnect the transmitter from
the main power supply. Install the
switch or breaker near the
transmitter and label it as the
disconnecting device for the
transmitter.
3.1.2 Analog output wiring
Four analog current outputs are
located on the main circuit
board, which is attached to the
inside of the enclosure door.
Figure 3-1 shows the location of
the terminals, the outputs they
are assigned to, and the polarity.
For best EMI/RFI protection, use
shielded output signal cable
enclosed in earth-grounded
metal conduit.
Keep output signal wiring separate from power wiring. Do not
run signal and power or relay
wiring in the same conduit or
close together in a cable tray.
FIGURE 3-1. Analog output connections.
The analog outputs are on the main board near the
hinged end of the enclosure door.
