PF2000 CONTROLLER for the
AQUARIUS® DEIONIZED WATER HEATING SYSTEM
1. INTRODUCTION
The Model PF2000 is a Programmable Logic Controller (Safety PLC) for the Heateflex
Corporation® Aquarius® DeIonized (D.I.) Water Heating Systems. It monitors and controls
all functions of the Aquarius® D.I. Water Heating Systems. Although its primary function
is to accurately control the temperature of the discharged D.I. water, it also provides
monitoring for incoming or input fluid temperature, output fluid temperature, fluid flow rate,
input voltage, input pressure, system alarms, and (optional) water resistivity.
The PF2000 receives data from various sensors in the Aquarius® Systems. Temperature
inputs are direct thermocouple connections. Separate individual thermocouples are used
for the input temperature of the ambient D.I. water, output temperature of the heated D.I.
water, and a thermocouple for each heating module in the Aquarius® D.I. Water Heating
Systems, serving as independent over-temperature safety interlock (HIGH LIMIT). A
liquid level sensor checks for the proper liquid level at the top of the final heating module.
A flow sensor checks the flow rate at the input of the first heating module (all heater
modules are configured in series). Pressure sensing is done with a pressure transducer
at the ambient D.I. water input. Incoming line voltage monitoring is done with a voltage
transducer at the step-down transformer at the power line. If the resistivity option is
present a resistivity sensor after the output module is also connected to the PF2000.
The PF2000 also includes a Safety PLC which monitors the high limit thermocouples
values and status (all of which are Type J thermocouples), status of thermal cut-off
sensors and status of ground fault circuit interrupter (GFCI). The Safety PLC logic
determines if there is an output on the Heater Master Relay and/or the Heater Safety
Relay which sets the system into STANDBY mode if there is an unsafe condition.

A Human Machine Interface (HMI) Touch Screen is utilized to operate the system, display
the status of the unit and display various alarm conditions. Once the Aquarius® System
is powered ON the Main Menu screen will appear, which is illustrated by Figure 1-1. The
touch screen allows the user to set up and adjust the system parameters and set points.
The screen also allows the user to monitor the flow rate, system pressure, voltage,
incoming and process temperatures through the System Status screen (See Section 5.1)
and displays the various system alarms on the Alarm Menu screen (See Section 7).
Figure 1-1: Main Menu Screen
The System Set Up Menu (See Section 6.1) is used to access system settings and
troubleshooting. These settings include Control Settings, Alarm Set Points, System
Calibration, Factory Setup, Ethernet Interface, and Option Settings. Note: A factory
password is required to access the Trouble Shoot Menu and Factory Set Up Menu.

2. BASIC TOUCH SCREEN FUNCTIONS
2.1.
UTILIZING THE TEN KEY
The Ten Key is a keypad used to enter numeric data such as temperature set
points and parameters throughout the PF2000 screens. Once the Ten Key
window is accessed, type in the desired value ensuring that the value is within
the maximum and minimum values that are indicated at the top of the Ten Key
keypad. If a wrong entry is made, use either the Back Arrow key to backspace
or the Clear key to clear the entire entry. Once the desired value is entered
correctly, select the Enter key to submit the value into the controller as shown
in Figure 2-1. If a change is not desired select the Cancel key to cancel the
operation.
Figure 2-1: Ten Key Window
2.2.
UTILIZING THE KEYBOARD
The Keyboard is a keypad (shown in Figure 2-2 and 2-3) used to enter
alphanumeric data such as passwords or text. Once this Keyboard window is
accessed, type in the value or characters desired. The Shift key is used to
enter capital letters and special characters, as shown in Figure 2-3. If a wrong

entry is made, use either the Back-Arrow key to backspace or the Clear key
to clear the entire entry. Once the desired value or characters are entered
correctly, select the Return key to submit the value into the controller as shown
in Figure 2-2. If a change is not desired select the Cancel key to cancel the
operation.

UTILIZING THE SYSTEM SCREEN KEYS
The system screen keys are used to allow the user to easily navigate the
touch screen. These keys are shown on the upper right hand corner, lower
right hand corner and lower left hand corner. The keys that are shown are
dependent on the current screen and may vary from screen to screen.

3. LOGIN
In some cases, it may be desirable to restrict access to the Aquarius® settings,
parameters and set points. With that in mind a Password System is incorporated into the
Aquarius® D.I. Water Heating Systems to limit access, prevent unauthorized access or
prevent unintentional changes to the system.
A username and password is required to access some of the parameters and set points
of the System Set Up submenus (Control Settings, Alarm Set Points, Options (if
available), and System Calibration). When a user level access is required, the user
must select the Login key at the upper right hand corner of the screen (see table 2-1 for
icon) to bring up the Login window. The user must enter the correct User Name and
Password with the proper credentials. Touch the input boxes within the Login window,
shown in Figure 3-1 below, to access the Keyboard window so that the User Name and
Password can be entered. (For instructions on how to use the Keyboard see Section
2.2) Once the correct User Name and Password are entered, select the Return key on
the Keyboard window and then select the OK key on the Login window. When the User
Name and Password is entered, the operator will gain access to the different settings,
parameters, and set points associated with the password level entered. The active User
Name will be shown at the upper right hand corner of the screen (See Figure 1-1). If the
controller is left idle for over one minute, the “password lock” will be activated which will
require the operator to re-enter the User Name and Password for access.
