CHAPTER I - INTRODUCTION
CHEMTROL® AUTOMATION
Congratulations on your selection of a CHEMTROL® CT
Controller Programmable Controller for your water treatment
facility.
CHEMTROL® Automation uses the most advanced electronic
sensing technology to monitor and control the critical
parameters for water treatment, i.e. conductivity, pH,
Oxidation-Reduction Potential (ORP) and temperature. Also
available is monitoring of flow rates for make-up and bleed
water and influent/effluent filter pressures.
This Instruction Manual covers the following models:
- CHEMTROL® CT110 with conductivity/TDS control, pH
control option, ORP control option, Temperature monitoring,
fill and bleed water flow programs, and three additives
programs.
- CHEMTROL® CT3000 with Conductivity/TDS control, pH
control, optional ORP control, Temperature monitoring, fill
and bleed water flow programs, and four additives programs.
- CHEMTROL® CT6000 with Conductivity/TDS control, pH
control, ORP control, Temperature monitoring, fill and
bleed water flow programs, four additives programs, water
level program, influent and effluent filter pressures, and
automatic filter backwash.
Webserver remote operation is available on all models.
Use the appropriate sections in the manual for each model.
Water Maintenance
The primary purpose of water treatment is protection of the
equipment from the aggressiveness of water and prevention of
bacteriological growth.
The guidelines for Commercial water chemistry controllers
include the following:
• Conductivity typically below 5,000 µS/cm -
corresponding to Total Dissolved Solids (TDS) of less
than 2,500 ppm (mg/l) - to prevent precipitation of
dissolved salts and corrosion products,
• pH between 7.0 and 9.0, depending on chemical
treatment, to prevent scaling or corrosion,
• Oxidation-Reduction Potential (ORP) above 650 mV
to prevent algae growth and growth of bacteria, such
as Pseudomonas, E. Coli, etc.,
• proper water balance with Langelier Saturation Index
values between 0 and 0.3 for untreated waters, or up
to 2.0 - for waters treated with phosphonates and/or
polyacrylates,
• adequate filtration with a maximum turnover rate of
six hours.
Reference Manuals
For more information on water treatment, see the Maintenance
section in this Instruction Manual or refer to one of the
following reference manuals:

MANUAL CT Controllers
CONTROLLER FEATURES
Integrated Water Treatment
Professional water treatment for Commercial water chemistry
controllers, and other industrial applications requires the
use of separate chemical and physical processes to
remove undesirable and harmful components.
The CHEMTROL® CT Controller is an advanced controller
that integrates all the different processes for complete
water treatment. Designed around a sophisticated
microprocessor with a large computer-like LCD (Liquid
Crystal Display) screen, it displays full-size menus and
submenus, making it easy to use and understand. All
displays and adjustments are accessible from menu screens
that are laid out in a logical and intuitive order. They can in
fact be used without reference to the instruction manual.
All sensing devices are connected to the controller. This
makes it possible to monitor the status of all operational
parameters at a glance. Also, in case of malfunction or alarm,
the operator is immediately alerted.
All control outputs are also connected to the single control
panel which makes installation and maintenance much easier
than with separate control units.
The central microprocessor manages all monitoring and control
functions, including control of the recirculation pump, chemical
additions, water balance and filter backwash.
Control Functions
The following display and control functions are available on the
CHEMTROL® CT Controller:
-Conductivity in microsiemens/cm or as Total
Dissolved Solids (TDS) in ppm or mg/l with
programmable bleed,
-Makeup Conductivity (CT112 only) in microsiemens
or as Total Dissolved Solids (MTDS) in ppm or mg/l,
with programmable cycles of concentration
-Temperature display in degrees Fahrenheit or
Celsius,
-pH from 0 to 14 with capability for programmable acid
and base feed,
-Oxidation-Reduction Potential (ORP or Redox) in
millivolts with programmable oxidizer feed,
superoxidation and chemical savings program,
-Sanitizer Concentration in parts per million (PPM) or
miligrams per liter (mg/l) with programmable sanitizer
feed, superchlorination, and chemical savings
program. This is available for Chlorine, Bromine,
Chlorine Dioxide, and Peracetic Acid.
-Water Flow with display of the flowrates for make-
up/fill and bleed water in gallons per minute (gpm) or
liters per minute (l/m), cumulative flows in gallons (ga)
or liters (l),
-Filtration with display of inlet and outlet pressures
and programmable filter backwashing based on
choice of time, inlet pressure, pressure differential or
combinations of the above.
-Additive Feed for inhibitors, biocides, descalers, etc.
- with choice of feed programs: manual, automatic
(bleed & feed or bleed-then-feed), cycle timer, percent
of flow, daily schedule or 2-week schedule controls
with bleed and feed lockout, pre-bleed and pre-pH
functions.
-Water Balance and Saturation Condition derived
from the Langelier Saturation Index and showing
water balance conditions as either OK, corrosive or
scaling.
In addition, a 24-hour clock/calendar shows the date and time
on the main screen. For other models that do not include all
the functions listed above, only the applicable screens and
menus are displayed.
Probe Failure Analysis
The CHEMTROL® CT Controller introduces a new proprietary
technology (US Patent No. 6,657,546) called Probe Failure
Analysis.
Conventional controllers detect probe failure by waiting for
an alarm condition to develop. The CHEMTROL®
CT Controller features dynamic testing of the response of the
ORP and pH sensors.
This makes it possible for the controller to detect a probe
failure immediately after the sensor fails to respond properly,
therefore avoiding dangerous out-of-range conditions.
Remote Communications
The CHEMTROL® CT Controller features complete
communication remote access by Ethernet connection
using Webserver interface, which gives you access through
any web-capable device; or PC-compatible software under
Windows®. This type of communication provides the
following capabilities:
-remote operation of controller with exact duplication of the
LCD screen display and full access to all the menus
and submenus,
-voice telephone report of test data,
-remote operational control,
-alarm callouts to a number of different pre-selected
telephone numbers through text; or to a number of
email addresses.
-automatic scanning of multiple facilities with
programmable download and storage of test data on
remote computer.
The Chemtrol® CT Controller units can also be made to
communicate to Energy Management Systems (EMS) or
Building Automation Systems (BMS) through different protocl
sets. Currently, the Chemtrol® CT Controllers can
communicate through Modbus, Lonworks, N2Bus, Bacnet
MSTP and Bacnet TCP/IP systems.
Remote Operation
Unlike controllers that provide only a simulated representation
of the display screen, the CHEMTROL® CT Controller
features true remote duplication of the controller screen.
This means that any change on the CHEMTROL® CT
Controller screen is immediately reproduced on the remote
computer screen. And vice versa, any operation that is
performed on the remote computer is reproduced immediately
on the controller.
The same commands are available on both units. This allows
instant verification and adjustment of all control parameters.
Changes in parameter settings are subject to password
verification to prevent unauthorized access.

OVERVIEW
The CHEMTROL® CT Controller constitutes an
integrated command center for complete monitoring and
control of all water treatment operations, including
chemistry and filtration.
All information provided by the sensors is processed by the
microprocessor on the Mother Board and displayed on the
Main Display screen. Command signals are then sent to the
different control outputs on the Power Board (see
ELECTRICAL below).
The schematic of installation in Figure 2 shows the principle of
installation for the CHEMTROL® CT6000 with all
options installed.
CHEMTROL® CT3000 and CT110 controllers without all the
above options are installed according to the same principles.
CONTROLLER CABINET
The CHEMTROL® CT Controllers are contained in
rain proof and splash proof NEMA Type 4X cabinets.
All electronic and electrical components are mounted inside
the cabinet on two separate PC Boards. Outlets are
provided on the bottom of the cabinet for ½" conduit
connectors.
The external dimensions of the cabinets and the positioning of
the mounting holes are shown in Figure 3 and Figure 4. To
deter unauthorized removal, the mounting holes are accessible
only from the inside of the cabinet. To facilitate installation
however, external mounting ears are also included.
LOCATION
The cabinet should be mounted on a wall in a secure location:
- meeting electrical code requirements,
- within 10' (3 m) of the main recirculation line or of the bypass
line - unless special extension cables are used for the
sensors,
- not exposed to direct sunlight as the LCD display screen will
darken at high temperature,
- easily accessible to maintenance personnel,
- if possible, in a separate room, or in a well- ventilated room
as far away as possible from corrosive chemicals and
storage tanks,
- away from power transformers, pump motors or high voltage
power lines,
- safe from unauthorized access or vandalism.

INSTALLATION MUST FOLLOW
ALL APPLICABLE ELECTRICAL CODES.
ELECTRICAL
Electrical Codes
The controller is available in either hard-wiring or plug-in
configurations. Make sure to use the proper type of wiring
according to the local electrical code, usually the same as for
the chemical feeders.
The internal wiring of the controller is standard US, i.e.:
BLACK HOT
WHITE COMMON
GREEN GROUND
Grounding (GFI)
A grounding lug is provided on the left side of the cabinet. It is
important to connect it to a proper earth ground to prevent
dangerous current leakage and electrical shock. Ground Fault
Interruption (GFI) protection is also strongly recommended for
all installations.
AC Power Input
The CHEMTROL® CT Controller is a dual-voltage
controller with a voltage selector switch located inside the
cabinet on the Power Board (see next page). Before
connecting the unit to an external power supply, make
sure that the voltage selector switch is set to the proper AC
power input: 115 V or 230 V.
CAUTION: Damage resulting from improper voltage
selection is not covered by manufacturer warranty.
Main Power Interlock
To prevent accidental chemical feeding, the controller and the
chemical feeders should always be interlocked -i.e. wired in
parallel -with the manual switch for the main pump so that
there is no danger of feeding the chemicals if there is no water
flow in the recirculation line.
Panel Interlock
For safety of operation, apanel interlock switch is mounted
inside the cabinet to shut off all internal power when the control
panel is open.
DO NOT ATTEMPT TO DEFEAT ITS PURPOSE !!!
PC Boards
There are two PC boards inside each controller cabinet: a
Power Board (Figure 5, or Figure 10) and a Mother Board
(Figure 11). They contain all the electrical and electronic
components for the controller. The two boards are connected
together with a flexible ribbon cable.
The schematics for the two boards show the location of the key
components. In addition, all components are also labeled on
the PC boards themselves.
The PC boards are protected with a 1 A fuse that is mounted
on the upper right of the Power Board. If the fuse has to be
replaced, make sure to use a one (1) Amp fuse only. The use
of a larger fuse may cause irreparable damage to the
electronic boards.
Power Board
The Power Board (Figure 5, or Figure 10) is mounted on
the back panel of the controller cabinet. As shown on the
schematic, it contains all the high voltage (115 or 230 V)
circuits and components for inputs and outputs.
115V/230V Power Transformer
The CHEMTROL® CT Controller is equipped with a
switchable, dual voltage power transformer that is mounted on
the Power Board inside the cabinet.
The voltage selector switch is located near the upper right of
the board. Always verify that the switch is set to the correct
voltage, either 115 or 230V. Connecting the controller to
higher voltage may cause damage to the electronics that is not
covered by the manufacturer’s warranty.

Relays and Fuses
The relays for the chemical feeders and other outputs are all
rated and fused at 5 A Slow Blow. Other signal relays are 2 A
at 30 V.
NOTE: The fuses for the Power Supply to the PC boards are
AGC-1 Fast fuses.
Make sure not to overload these relays. Chemical feed pumps
normally draw less than 5 A. However, if a pump draws more
than 5 A, it will need a motor starter or a magnetic switch.
NOTE: Depending on options selected, not all relays may be
included on the Power Board.

Remote Alarm
On the CT6000, CT3000 and CT110, the remote alarm is a 5A
DPDT relay located on the upper right corner of
the Power Board. The remote alarm relay can be set for
dry or hot contacts, or for any external signal.
To avoid damaging the Power Board, make sure to use the
right type of contacts. Call your dealer or the factory if you
are not sure.
With hot contacts, the controller powers the alarm with 110 or
230V, depending on the setting of the input voltage selector
switch (see preceding page). Connect the leads to the alarm
to the Normally Open contacts (NO1 and NO2) on the terminal
strip located next to the alarm relay.
With dry contacts, remove the shunts from J4 and J5 located
below fuses marked F7 and F6. Wire the remote alarm to NO1
and C1.
For an external power source, wire the input power to the
terminals marked NC1 and NC2. Wire the remote alarm to the
normally open contact (NO1 and NO2). The alarm voltage will
be the same as the external power source
Mother Board
The Mother Board (Figure 6 and Figure 8) is mounted directly
behind the face panel of the controller and contains all the low
voltage circuitry including the microprocessor and program
chips, the LCD display and the keyboard pad.
The key features of the motherboard are the microprocessor,
the uSD Card Socket for program updates and data
downloads; the Ethernet communication connection; and the
pH and ORP sensor connections. These senosr connections
are brought to the outside of the enclosure; and can be seen
on the left side of the enclosure.
Sensor Connections
When included in the original controller order, all ot the sensor
connections are available on the outside of the cabinet via
bulkhead connectors. The conductivity sensor is included in all
controllers; and is marked on the outside of the cabinet as
TDS/Temp.
For the sake of field upgrades, the sensor connections for each
of the following functions are connected to Terminal Barrier
Strips in these locations:
CT110 Power Board

5= +5V
6=Flow Meter 1 Fill Water Meter Signal
7= Paddlewheel 2 Bleed Water Meter Signal
8= GND Ground
9=SIG Flow Switch Signal
10=GND Flow switch Ground
11= +24V Available for Powered Water Meter

In the CT110, the pH and ORP sensors will be
connected internally on the Motherboard (see Figure
8). The Conductivity/Temperature connections are made
on the Power Board, at TB!, positions 1-4. Any other sensor
inputs will be made on expansion cards. (See Figure 9 and
Figure 10).

INSTALLATION
MANUAL CT Controllers
Backup Battery
The 3V Backup Battery is located on the upper left of the
Mother Board. It is used to maintain the memory settings in
case of loss of AC power. This battery is designed to last for
several years in normal operation and for up to six months if
the AC power is shut off.
Under normal conditions, the controller will operate without
battery power. However the clock and other memory settings
will have to be restored in case of complete power shutdown.
The battery should be replaced if the voltage falls below 2.6 V.
This can be verified at any time in the Configuration Menu
using the Battery Submenu.
Remote Communications
There are several remote communications options for the
Chemtrol® CT Controllers. I will briefly cover each option
here.
Webserver Communications
Each of the Chemtrol® CT Controllers can be equipped with
an interface that will allow the user to access the
controller through any web-capable device.
The Webserver Option can be configured to work in either of
two ways: through the facility’s local area network (LAN); or
through a cellular modem to the internet.
Each Chemtrol® CT Controller is configured with a
unique MAC address, which is used for these type of
communications.
In order to work through the facility’s LAN, the facility will need
to allow access through their firewall. In many cases, the
Information Technolgy (IT) Department of the facility can
provide secure access through their firewall. In this type of
case, Chemtrol would provide a form to be filled out with the
access information from the facility. The Chemtrol IT
Department will configure the MAC address and access
information into the Chemtrol® Webserver. At that point, the
facility would only need to bring a standard Ethernet cable to
the controller; and the communication would be initiated.
Some facilites disourage this type of access into their network.
In these cases, Chemtrol® can provide the Webserver access
through a Cellular Modem. This solution requires that the
facility (or service provider) obtain and maintain a service
contract for the use of the cellular modem. This would not
involve any access to the facility LAN.
4-20 mA Output Boards
There are several 4-20 mA Converter Boards available for the
Chemtrol® CT Controllers. They all work essentially the
same way. They provide two connection terminals for the
output current. There purpose is to convert the digital outputs
of the controller into analog signals that can be used by
analog monitoring and control equipment.
If the boards are installed properly, the controller software
automatically shows the 4-20 mA menu line in the Submenu
8.3 - Communications.
Page 18
Field Installation
For field installation, turn off all power to the controller.
Position the converter board over one of the expansion slots
on the controller’s power supply board. Press the female
electrical connector of the output board onto the male header
of any of the power board expansion slots. Use the instrument
screw provided to secure the other end of the output board into
the expansion slot.
The signal assignment of each pair of terminals will be clearly
marked on the output card.
Building Management System (BMS) Communications
All of the Chemtrol® CT Controllers can be equipped
to communicate to the facility Building Management
System using a number of open protocol languages.
The most common of these languages being used today
are: Modbus, Bacnet IP, Bacnet MSTP and Lonworks. The
controllers can be configured with any of these languages.
To enable this type of communication, there will be amodule
installed inside the controller which will convert the language of
the controller to the open protocol language. (See Figure 12.)

PLUMBING
Plumbing includes installation of the sensors and connection of
the chemical feeders or control valves.
Installation of Sensors
The CHEMTROL® CT Controller can use many sensors
for measurement of water chemistry. For this discussion, we
will restrict that list to: conductivity, temperature, pH, ORP,
flow rate, pressure and water level:
- conductivity sensor for Total Dissolved Solids,
- potentiometric sensors for pH and ORP,
- thermistor for temperature,
- Hall effect pulse generator for flow rate,
- piezoelectric sensors for influent and effluent pressures,
- electro-optical water level sensor.
On small recirculation lines (2-inch pipe), the water chemistry
sensors (conductivity, pH, ORP and temperature) can be
installed directly on the main line using PVC reducing tees
(Figure 16).
On larger lines, the sensors should be mounted on a bypass
line, using either a Sample Line Assembly (Figure 17) or a
Sensor Cell Cabinet (Figure 8).
In-line Installation (2" Pipe)
Use only 2x2x3/4 in. SST reducing tees without reducers. Do
not install the sensors near an elbow or a constriction where
there might be excessive turbulence.
Install the tees on the suction side of the pump and make sure
that the tip of the sensor is oriented downward - as shown in
Figure - to avoid formation of air pockets near the tip. The
sensors should be readily accessible for servicing but not
exposed to physical damage.
After inserting the sensor, be careful not to overtighten the
compression fitting as it can crush the small glass tube inside
the sensor. Make it finger tight (no wrench).
Figure 16 - Sensor Tee
Sample Line Installation
The CHEMTROL® Bypass Line Assembly (P/N FSLYCT2)
shown in Figure is recommended for installation of the
sensors. It is designed to assure a smooth and reliable flow of
water. It includes:
- PVC tees (3/4" SST),
- Fast & Tite fittings (3/4" MPT),
- In-line Y-filter (3/4" MPT),
- On/off flow switch (3/4" FPT),
- Two Union Connections
-Ball valve for water sampling and testing.
The Bypass Line Assembly should be installed exactly as
shown on Figure .In particular, make sure to install the
flowmeter in avertical position and to install the flow switch
downstream of (after) the sensors to assure a smooth flow of
water near the sensors.
Figure 17 – CT Controller Sample Line Assembly

INSTALLATION Page 20
MANUAL CT Controllers
Sensor Cell Cabinet
For ease of installation and maintenance, the components of
the bypass line assembly can also be supplied in apre-
plumbed Sensor Cell Assembly, also named Wet Box. As
shown in Figure 18, the Wet Box is mounted in aseparate
fiberglass cabinet containing the sensor cell. It should be
mounted on a½" bypass line with Y-filter, flowmeter and
paddlewheel safety flow switch.
Make sure that the Sensor Cell Assembly is located within 10'
(3 m) of the controller cabinet or order sensor extension cables
(see Sensor Cables).
See the wiring instructions in the ELECTRICAL section and the
operational instructions under WATER FLOW below.
Water Flow
Proper flow of water past the sensors is essential to obtaining
good readings. To check the water flow in the bypass line,
start the main recirculation pump. Open any isolation valves
on the bypass line and see the flow past the flow switch. If
there is no water flow, replumb the bypass line as shown on
the schematic.
NOTE: The most common installation problems with bypass
line or wet box installations are caused by faulty hydraulics.
To ensure proper water flow, make sure that the intake side of
the bypass line is connected to the pressure side of the
recirculation system and that the return side is connected to a
low pressure area -such as the vacuum side before the
recirculation pump, or low pressure downstream
On/Off Flow Switch
An on/off-type flow switch is recommended with the
CHEMTROL® CT Controller to prevent accidental feeding
when there is no water flow.
If you purchase the flow switch with the controller, the flow
switch connection will be available on the left side of the
cabinet, marked Flow Switch. If you have apreference for
another type of flow switch, you can make the flow switch
connections on TB1 of the Power Supply Board (See Figures 5
and 7) at the Terminals 9 and 10.
