ESSENTIAL INSTRUCTIONS

READ THIS P

AGE BEFORE PROCEEDING!

Your purchase from Rosemount Analytical, Inc. has

resulted in one of the finest instruments available for

your particular application. These instruments have

been designed, and tested to meet many national

and international standards. Experience indicates

that its performance is directly related to the quality

of the installation and knowledge of the user in oper-

ating and maintaining the instrument. To ensure their

continued operation to the design specifications, per-

sonnel should read this manual thoroughly before

proceeding with installation, commissioning, opera-

tion, and maintenance of this instrument. If this

equipment is used in a manner not specified by the

manufacturer, the protection provided by it against

hazards may be impaired.

• Failure to follow the proper instructions may cause

any one of the following situations to occur: Loss

of life; personal injury; property damage; damage

to this instrument; and warranty invalidation.

• Ensure that you have received the correct model

and options from your purchase order. Verify that

this manual covers your model and options. If not,

call 1-800-854-8257 or 949-757-8500 to request

correct manual.

WARNINGS

RISK OF ELECTRICAL SHOCK

Equipment protected throughout by double insulation.

• Installation of cable connections and servicing of this

product require access to shock hazard voltage levels.

• Main power and relay contacts wired to separate power

source must be disconnected before servicing.

• Do not operate or energize instrument with case open!

• Signal wiring connected in this box must be rated at least

240 V.

• Non-metallic cable strain reliefs do not provide grounding

between conduit connections! Use grounding type bush-

ings and jumper wires.

• Unused cable conduit entries must be securely sealed by

non-flammable closures to provide enclosure integrity in

compliance with personal safety and environmental protec-

tion requirements. Unused conduit openings must be

sealed with NEMA 4X or IP65 conduit plugs to maintain

the ingress protection rating (NEMA 4X).

• Electrical installation must be in accordance with the

National Electrical Code (ANSI/NFPA-70) and/or any

other applicable national or local codes.

• Operate only with front and rear panels fastened and in

place over terminal area.

• Safety and performance require that this instrument be

connected and properly grounded through a three-wire

power source.

• Proper relay use and configuration is the responsibility of

the user.

CAUTION

This product generates, uses, and can radiate radio frequency

energy and thus can cause radio communication interference.

Improper installation, or operation, may increase such interfer-

ence. As temporarily permitted by regulation, this unit has not

been tested for compliance within the limits of Class A comput-

ing 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 user at his

own expense, will be required to take whatever measures may

be required to correct the interference.

WARNING

This product is not intended for use in the light

industrial, residential or commercial environments

per the instrument’s certification to EN50081-2.

CFA-3000 Colorimetric Analyzer

Instruction Manual

The Rosemount Analytical CFA-3000 Series analyzers are designed for minimum

maintenance and maximum reliability. The touch of a button starts the microprocessor-

controlled program, calibrates the analyzer, keeps it calibrated, and reports results directly

- unattended - for months at a time. Maintenance is simplified by a modular design with

quick disconnect fittings, labeled tubing, and color-coded components.

The CFA-3000 Series includes analyzers for many common chemical parameters,

including: silica, phosphate, hexavalent chromium (Cr+6), iron, copper, and ammonia.

Sample concentration is clearly indicated on the digital display panel, and output signals

are provided to drive recorders, alarms, or other external devices such as printers or

computers. The specific chemistry of your individual analyzer is discussed in Appendix A,

Chemistries.

Your purchase from Rosemount Analytical provides you with one of the finest instruments

available for your particular application. These instruments have been designed and

tested to meet many national and international standards. Experience indicates that its

performance is directly related to the quality of the installation and knowledge of the user

in operating and maintaining the instrument.

2.6 Prepare Electrical Connections

Electrical connections are made to and from the cabinet at the input/output panel, located on

the left side of the analyzer. See Figure 2-5.

 Terminals are provided for ground, power supply, high/low alarms, output signals,

calibration and status relays

 .Output signals - a voltage output of 0-5 Vdc and a floating, ungrounded current

output of 4-20 mA are available for remote readout or control of a process.

 Also available are contact closures for the following:

High alarm Leak Alarm

Low Alarm Lamp Alarm

Calibration

To make electrical connections, proceed as follows:

1. Remove solid caps from the holes above the input/output panel by puncturing with an

awl and prying them out. (Note: remove caps only from those holes that will be used.)

2. Replace with permanent connectors.

3. Connect alarms and external computer interfaces (if any).

4. Feed 3-wire power cable into analyzer through hole above the input/output panel.

5. Connect wires to appropriate contacts on Terminal Strip TB3.(See next page)

WARNING:

Connect output signals, if any, before connecting the power supply.

CAUTION:

 For proper operation and for safety, electrical connections to this equipment

must be made in accordance with local or national electrical code as applicable.

 This equipment must be grounded. A qualified electrician should wire this

equipment to an electrical circuit.

2.8 Install Valve Pump Assembly

The pump assembly has a vacuum pressure system that:

o Eliminates internal pump tubing

o Uses significantly less reagent

o Accurately moves fluids through the analyzer.

Perform the following procedure to install valve pump assembly:

1. Tilt pump assembly towards you.

2. .Align the hinge pins and sockets, and slide assembly tray as far as possible to

right (see Figure 2-7). Carefully lay tray down into cabinet

3. Plug in the two connectors to the back of the cabinet (6-position connector for

heating bath; 9-position connector for pump) (see Figure 2-8).

4. Connect 16-pin connector from pump assembly to small connector on CPU board

(yellow ejector) above connector for keypad panel.

5. Attach colorimeter inlet tubing on left side of pump to flowcell inlet (see Figure 2-

1).

6. Continue with procedure depending on whether system is single-stream or multi-

stream

For single-stream, continue:

6. Thread tube labeled Sample" through hole 0n bottom of shelf to the right of pump

assembly, and out through hole on left side of cabinet.

7. Connect Sample tube to top of overflow sample on left side of cabinet.

8. Guide all other tubes that are attached to valve pump assembly through reagent

cabinet access hole.

For multi-stream, continue:

6. Thread Sample tube from pump assembly through reagent access hole on the

right side of the valve pump assembly, and connect to Common (C) on #1 multi-

stream solenoid valve on left side of reagent cabinet.

Guide all other tubes that are attached to valve pump assembly through reagent cabinet

access hole.
