The CHEMTROL® PC2000 Controller features automatic control of ORP and pH with display of the Langelier Saturation Index.

Options include ppm readouts, conductivity (or TDS) and temperature monitoring and remote control with true duplex operation.

Compatible with all common sanitizers and oxidizers.

NOTE: ORP sensors are not recommended with electrolytic chlorine generators.

A FULLY PROGRAMMABLE CONTROLLER

The CHEMTROL® PC2000 controller is a simple and reliable programmable controller that features automatic maintenance of water chemistry (pH and ORP) with acid or base feed, programmable superchlorination and chemicals savings cycles and display of the Langelier Saturation Index.

The four-line Main Screen display enables the operator to supervise all process functions at a glance and to quickly respond to any changing condition.

The CHEMTROL® PC2000 controller operates like a computer with multi-line screen displays and direct access to all menus and submenus. The front panel keypad is used to move up and down each menu and enter or exit the submenus. All operating functions can be easily modified from the keypad, including sensor calibration, control setpoints, alarm levels and the programs for superchlorination and chemical savings.

With the Remote Operations feature, all facilities can be monitored by remote computer. This allows real-time supervision by management and remote troubleshooting by a CHEMTROL® Qualified Dealer or by the factory support department. The remote operation option makes it possible to control all operating functions from a remote PC computer. NOTE: The voice telephone communications option is available on the CHEMTROL® PC3000 and CHEMTROL® PC6000 Controllers.

OPERATION

The Main Display Screen of the CHEMTROL® PC2000 Programmable Controller gives direct access to all the menus and submenus. Navigation between the menus and inside the menus is easily accomplished with the four directional arrow keys. Numerical settings can be changed with the ten-key keypad.

NOTE: Several of the menus and submenus of the CHEMTROL® PC2000 extend beyond the four lines of the display. The additional lines are accessed by continuing to press the Down arrow after reaching the bottom of the screen. The Up arrow is used in the same way to display the upper lines.

ORP and pH

By constantly monitoring the pH of the water and the activity of the sanitizer (ORP), Chemical Automation makes it possible to maintain clean and safe water at all times with a significant reduction in the cost of chemicals, maintenance and repairs. It is now recognized as a must for all commercial and public pools and spas, as well as for quality residential installations.

ORP is used to monitor the Oxidation-Reduction Potential in the water produced by a true oxidizer, like ozone, or an oxidizing sanitizer, like chlorine or bromine.

The ORP MENU includes selection of the control mode (Off, Manual, Auto or Timer), sensor calibration (1, 2 or 3 points), setpoint level, high and low alarms, shocking and chemical saver programs. It also displays the run time for the current feed event and cumulative run time. Shock treatment can be initiated manually or under programmable weekly or multi-weekly schedules.

The pH MENU is used in the same way to select the pH control parameters using either acid or base feed or both. It also includes an Acid Wash program for periodic injection of an acid rinse solution to clean the heads of the sensors.

SATURATION AND WATER BALANCE

Proper control of saturation and water balance is required to maintain water quality and to avoid the development of scaling or corrosive conditions.

The Conductivity sensor monitors the concentration of dissolved solids by measuring the conductivity of the water. The data can be displayed either in conductivity units (microsiemens/cm) or in parts per million of Total Dissolved Solids (TDS), using an operator-selectable conversion factor.

The TDS MENU is used to set automatic dumping (bleeding) of water when the dissolved solid concentrations becomes too high, selecting either a Conductivity or a TDS control setpoint to activate the dump valve. Refilling of water can be done simultaneously with a level control activated valve.

The Langelier Index calculates the saturation condition from the pH and Temperature sensor inputs and from manual data entry for Alkalinity and Calcium Hardness. The water saturation condition is constantly displayed on the Main Screen as either "OK", "Scaling" or "Corrosive" using standard Langelier Index limits. If a scaling or corrosive condition develops, it is immediately indicated with a flashing display on the Main Screen. "What if" analyses can be run at any time by manually entering different values for alkalinity, calcium hardness, pH and temperature.

TEMPERATURE MENU

Temperature Sensor readings can be displayed either in degrees Farenheit or Celsius. The TEMPERATURE MENU is used to calibrate the temperature sensor using 1, 2 or 3-point calibration and to set high and low alarms.

SETUP MENU

The SETUP MENU is accessed from the Main Menu by pressing the down arrow after reaching the bottom of the screen. This menu is used to modify the configuration parameters for initialisation, operations and communications from their initial defaut values. These values can be changed at any time or restored to the original default values.

INSTALLATION

Installation of the CHEMTROL® PC2000 controller is quite simple, as shown on the schematics below.  To facilitate specification and field-installation, the following schematic drawings are offered in several formats: to be printed directly on a printer (acrobat reader pdf), or to be inserted directly into CAD drawings (AutoCAD format).

Even though the sensors may be mounted directly on the main recirculation line (2" only), it is usually recommended to install them on a bypass line or in a CHEMTROL® Flow Cell Assembly (FCA), as shown below, for better protection as well as smooth waterflow and ease of installation and maintenance.
