CAUTION

Radio interference

This product generates, uses, and can radiate radio frequency energy and thus can cause radio
communication interference. Improper installation or operation may increase such interference. As
temporarily permitted by regulation, this unit has not been tested for compliance within the limits of
Class A computing devices, pursuant to Subpart J of Part 15 of FCC rules, which are designed to provide
reasonable protection against such interference.

Operation of this equipment in a residential area may cause interference, in which case the
operator, at his own expense, will be required to take whatever measures may be required to
correct the interference.

WARNING

Physical access

Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end
users’ equipment. This could be intentional or unintentional and needs to be protected against.

Physical security is an important part of any security program and fundamental to protecting your
system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for
all systems used within the facility.

General installation information

1. Although the system is suitable for outdoor use, do not install it in
direct sunlight or in areas of extreme temperature.

Quick Start Guide January 2020

CAUTION

Hazardous areas

The system is not suitable for use in hazardous areas.

2. Install the system in an area where vibrations and electromagnetic
and radio frequency interference are minimized or absent.

3. Be sure there is easy access to the transmitter and sensor(s).

2.3 Sample requirements

Be sure the sample meets the following requirements:

1. Temperature: 32 to 122 °F (0 to 50 °C )

2. Pressure: 3 to 65 psig (122 to 549 kPa abs)

3. Minimum flow: 3 gal/hr (11 L/hr)

2.4 Mounting, inlet, and drain connections

The Rosemount™ FCL is intended for wall mounting only.

Refer to Figure 2-1 or Figure 2-2 for details. The sensor(s) screw into the flow
cell adapters as shown in the figures. For Rosemount FCL-02 (free chlorine

A ¼-in. OD tubing compression fitting is provided for the sample inlet. If
desired, you can remove the compression fitting and replace it with a barbed
fitting. The fitting screws into a ¼-in. FNPT check valve. The check valve
prevents the sensor flow cell from going dry if sample flow is lost.

The sample drains through a ¾-in. barbed fitting.

1. Attach a piece of soft tubing to the fitting and allow the waste to
drain to open atmosphere.

Important

Do not restrict the drain line.

2. Adjust the sample flow until the water level is even with the central
overflow tube and excess water is flowing down the tube.

3. Confirm that sample is flowing through the flow cells.

2.5 Install the sensor(s)

Emerson provides the Rosemount™ FCL with the sensor cable pre-wired to
the transmitter.

Procedure

1. Connect the chlorine sensor (Rosemount 499ACL-01-54-VP) to the
cable labeled CL.

2. Connect the pH sensor (Rosemount 3900-VP-02-10) to the cable
labeled pH.

The terminal end of the sensor is keyed to ensure proper mating with
the cable receptacle.

3. Once the key has slid into the mating slot, tighten the connection by
turning the knurled ring clockwise.

4. Screw the sensor(s) 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.

3 Wire

3.1 Wire power

Wire AC mains power supply to the power supply board, which is mounted
on the left hand side of the transmitter enclosure beneath the gray plastic
cover.

WARNING

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.

Procedure

1. 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.)

2. Provide a switch or breaker to disconnect the transmitter from the
main power supply.

3. Install the switch or breaker near the transmitter and label it as the
disconnecting device for the transmitter.

Quick Start Guide 13

Quick Start Guide January 2020

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.

Quick Start Guide January 2020

Procedure

1. To remove the cover, grab it by the upper edges and pull straight
out.

The relay strip is at the top of the terminal board. See Figure 3-2.

2. Bring the relay wires through the rear conduit opening on the left
hand side of the enclosure and make connections to the terminal
strip.

3. 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 on the front of the cover snap
into the three tabs next to the relay terminal strip. See Figure 3-2.

Keep alarm wiring separate from signal wiring. Do not run signal and
power or relay wiring in the same conduit or close together in a tray.

3.4 Wire sensor

The Rosemount™ FCL is provided with sensor cables pre-wired to the
transmitter. If it is necessary to replace the sensor cable, refer to the
instructions below.

Procedure

1. Shut off power to the transmitter.

2. Loosen the four screws holding the front panel in place and let it drop
down.

3. Locate the appropriate signal board.

Slot 1 (left)

communication input 1 (chlorine) input 2 (optional)

Slot 2 (center) Slot 3 (right)

4. Loosen the gland fitting and carefully push the sensor cable up
through the fitting as you pull the board forward to gain access to the
wires and terminal screws.

5. Once the cable has been connected to the board, slide the board fully
into the enclosure while taking up the excess cable through the cable
gland.

6. Tighten the gland nut to secure the cable and ensure a sealed
enclosure.

3.5 Quick Start

Procedure

1. Once connections are secured and verified, apply power to the
transmitter.
When the transmitter is powered up for the first time, Quick Start
screens appear.

a. The cursor, shown by dark blue backlighting, is on the

language control box. To change the language, press the
ENTER/MENU key. A list of available languages, shown two at
a time, appears. Using the Up and Down keys, scroll (see ) to
display the choices. Press ENTER/MENU to select the desired
language. Press Down to move the cursor to the temperature
control box. To change units, press ENTER/MENU and scroll
to either °F or °C. Press ENTER/MENU to store the selection.

b. To move to the next screen, use the navigation keys to move

the cursor to NEXT and press ENTER/MENU.

2. The next screen lists navigation rules. Press ENTER/MENU for the
next screen.

3. Configure sensor 1.
Sensor 1 is the free chlorine sensor. The screen has three control

boxes.

a) For measurement, choose Free chlorine.

Important

Do not choose pH-independent free chlorine.

b) Choose the desired units, mg/L or ppm.

c) If you have a Rosemount™ FCL-02 (with pH sensor), the third

control box lets you choose between live/continuous or
manual pH correction.
If you choose live/continous (recommended), the transmitter
will use the pH measured by the pH sensor to correct the
chlorine reading for pH changes. If you choose manual (not
recommended), a fourth control box appears to let you enter
the manual pH, and the transmitter will use the entered value
to correct the chlorine reading.

d) If you have a Rosemount FCL-01 (no pH sensor), enter the pH

of the process liquid in the third control box.

e) Move the cursor to NEXT and press ENTER/MENU. If you have

a Rosemount FCL-01, the display changes to show some basic

Quick Start Guide 17

Quick Start Guide January 2020

keypad operation guidelines. Press ENTER/MENU to show the
main display. If you have a Rosemount, go to the next step.

4. Configure sensor 2.
Sensor 2 is the pH sensor. The screen has two control boxes.

a) For measurement, choose pH.

b) For pre-amplifier location, choose analyzer.

c) Move the cursor to NEXT and press ENTER/MENU. The display

changes to show some basic keypad operation guidelines.
Press ENTER/MENU to show the main display.

The outputs, alarms, display configuration, and data logging are all assigned
to default values. The default value for data logging is disabled.
