FWT SYSTEMS: Measuring and Control instruments

FWT® controllers feature various functions for continuous measurements and different levels of operating modes

and programming procedures. FWT® controllers are suitable to cover a wide range of technical requirements,

safety and able to match different price demands. Two series are available:

TOUCH series

TOUCH series is a multifunction system with touch screen display, chemical parameter controller and a management

control system. TOUCH series is a work-in progress controller: the featured functions make it the most versatile controller

unit on the market. The alphanumerical touch screen and an internal timer allows the operator to allocate each auxiliary

output according to the system requirements thus creating a full customization.

TOUCH series can be appropriately to be consider a Central

management unit for Industry, water systems, BMS (Building

management system) and Domotic applications. Along with high

quality performance in terms of measurements and functions Touch

screen is easy to operate as most of the people are accustom to the

latest smart equipment.

CTRL series

CTRL is a compact controller series with many functions and models, which make the unit extremely versatile, and covers

different type of requirement. Simple and price effective CTRL series tops more sophisticated unit in terms of

measurements and functions thus satisfying most of the requirements for an instrument. Any model will always feature high

quality measurement and functions performance.

Some of the models within CTRL series feature also functions that allow

external auxiliary outputs to complement the unit to most of systems

requirements to obtain a complete management control from parameter

measurements to control other equipments included in the system.

CTRL SERIES PROGRAMMING FEATURES

CTRL series PROGRAMMING MENU

FWT controllers feature two programming menu:

- Basic menu with simplified functions;

- Expert: complete programming including functions for more refined control and results.

TOUCH series

SELECTING MEASURING PARAMETER PH/RX

Measuring parameter can be changed from PH to RX and consequently changing display and measurement data and programming parameter settings.

SELECTING CHLORINE MEASURING RANGE

Chlorine controller is set as for 4 ranges:

- Membrane type ion selective sensor, covering ranges 0-2 ppm; 0-20 ppm; 0-200 ppm;

- Open chlorine cell (CLC3 model) range 0-10 ppm

CHANGING VALUES

- CTRL series has a keyboard with buttons for changing values placed on the front panel;

- TOUCH series shows a keyboard where operator can touch the screen for changing values;

AUXILIARY OUTPUTS

Auxiliary outputs can remote control various functions related to external equipment and dosing pump including automatic

Open chlorine cell cleaning. Each output can drive remote equipment or devices according to a very accurate programming

of minutes/hours/days/weeks.

AUX1 output can be set for remote control of external equipment or for a cleaning program of Open Chlorine cell (FWT

series CLC); other AUX outputs only have remote control external equipment.

CTRL series

Operator can program the working days and weeks and

the exact time of the unit operations (ON-OFF mode).

Program settings features many steps, which can be programmed to have the most

accurate operation with absolute precision (up to 99 programs for each AUX output).

TOUCH series

Once choosing edit, a keypad will appear on the touch screen for selecting required values.

COOLING TOWERS CONTROLLERS

FWT COMPREHENSIVE SOLUTIONS FOR COMPLETE COOLING TOWER SYSTEM

CTRL EC COOL

CTRL B EC COOL

FWT has many years of experience and a comprehensive product range for

all processes connected with cooling water conditioning, in a wide variety of

designs for every application.

CTRL EC COOL is a compact system for cooling tower control for

centralising control that addresses the operation of cooling towers in a

practical and economic way, specially designed for cooling water treatment

and blow-down operations, air scrubbers and humidifiers of any industrial

air-conditioning systems.

The controller integrates other process equipment such as: a range of

Conductivity sensors (according to measuring range) and versatile control

options for flow meters, blow-down solenoid or flap valves.

MODELS AVAILABLE

CTRL EC COOL

CTRL2 PHEC COOL with the addition of PH (or RX/ORP) controller.

ENCLOSURE CHARACTERISTICS

CTRL EC COOL is available with 2 plastic enclosures:

- CTRL enclosure IP65, ABS plastic - V0 (fireproof)

- CTRL B enclosure IP56 ABS plastic - UL94 HB

EC COOL is capable of: • Automatically monitoring total dissolved solids and desalination through

CONDUCTIVITY measurements, driving an electro valve or via TIMER;

• Accurate dosing control of scale inhibitors and biocides;

• Corrosion inhibitor dosing via four modes;

• Dosing for two biocides dosing pumps;

• Biocide cycles via timer programming;

• Automatic blow-down operation lockout and pre-bleed operations;

• 4-20mA analog current output mode for remote control equipment;

• Flow sensor (proximity switch) function;

• Level control for external chemical tanks

BLEED OPERATIONS

CTRL EC COOL controller offers two modes concerning the Bleed mode (blow-down) operations of the EV:

TIMER mode: the internal timer independently of the conductivity level in the cooling tower will drive the EV.

CONDUCTIVITY mode: it processes the conductivity level to control blow-down operations.

INHIBITOR DOSING CONTROL OPERATIONS CTRL EC COOL controller features 4 inhibitor dosing pump operations modes:

BLEED DIRECT starts Inhibitor dosing when the bleed valve is open (works in parallel to EV);

BLEED % inhibitor is dosed after EV closing in % time equal to the last discharge time duration;

TIMER inhibitor dosing via an internal Timer: at the start of each period, dosing pump will work for a pre-set time;

WATER METER is active during the re-integration of makeup water and is driven by external water meter

pulse proportionally to flow.

BIOCIDE DOSING CONTROL OPERATIONS

CTRL EC COOL features 2 Biocide dosing programs. Most cooling tower systems include two biocides programs to ensure

efficient disinfection quality. Internal timer controls two dosing pumps and various metering processes.

- TIME PROGRAMMING: Biocide mode features many steps to have the most accurate dosing operation with

absolute precision: Program number (up to 99 programs for each biocide); Biocide dosing pump active Time

cycle; Biocide dosing pump start dosing time; Biocide dosing pump operating days, week of the month.

- BLEED LOCK OUT TIME: Biocide Lock-out mode: EV bleed operations, Inhibitor dosing pump and Biocide2

dosing pump are stopped for the duration of Biocide operations thus avoiding chemical waste.

- PRE-BLEED TIME: Lower conductivity then selected set point (Set point HIGH) enabling desalination before

biocide dosing and disabling bleed EV afterwards.

REMOTE CONTROL FEATURES

Both TOUCH and CTRL+, CTRL 2/6 and CTRL3 series are suitable for remote control

by RS485 expansion board with Modbus protocol using FWT SmartApp® software.

ETHERNET connection allows the operator to connect to the unit via pc, smartphone or

tablets and change programming and settings using FWT SmartApp® software. Unit will

signal once reaching alarm level, overdosing settings or Max dosing pump time out.

WIFI connection allows the operator to control in real time TOUCH series operations via

Internet by PC, Mac, Tablets and Smartphone (WiFi pen drive not included).

A self-explanatory program allows changing settings and programming. Unit will send

an email once reaching alarm levels, overdosing point or Max dosing pump time out.
