Electrical Shock Hazard
CAUTION: The operator of this instrument is advised that if the equipment is used in a
manner not specified in this manual, the protection provided by the equipment may be impaired.
Opening the controller enclosure with the controller plugged in, exposes the user to AC line voltages on the lower of the two controller circuit boards.
Ground the controller AC power to the ground screw labeled and located on the bottom, right of the aluminum backplate.
External, 120VAC plug boxes are provided with controllers installed in North
America External plug boxes are grounded to the ground screw labeled located on the bottom, center of the aluminum backplate.
USER WARNING : CAUTION
Water Treatment Controllers operate steam and water valves and may pump hazardous, corrosive and toxic chemicals. Opening the controller enclosure exposes user to the risk of electrical shock at power line voltages.
Understand fully the implications of the control setpoints, interlocks and alarms that you select. Harm to personnel and damage to equipment may result from mis-application.
Unplug or turn OFF the AC power to the controller if you have any concerns regarding safety or incorrect controller operation and notify supervisory staff.
YOUR CONTROLLER
Controllers are supplied in many different configurations.
The HELP section in the back of this manual contains the information for terminating the sensors supplied with your specific controller.
The HELP section in the back of this manual depicts the installation plumbing header showing the sensor set supplied with your specific controller.

ONE CONTROLLER – MANY APPLICATIONS
Controllers are shipped configured with a wide range of sensors
for one or more cooling towers, multiple boilers, hot & chilled closed loops,
condensate monitoring, waste water control and monitoring…
YOUR CONTROLLER – SENSOR SET
The installation instructions for your specific controller are
in the HELP section YELLOW pages.
HELP is the last tab in the manual binder.
YOUR APPLICATION CHANGES
The controller can be completely reconfigured using the keypad or optional browser
Feed methods and interlocking can be changed.
pH control can be switched to ORP
A tower controller can be switched to waste water or boiler-condensate controls
You need to automate sensor cleaning, measure more water meters,
Feed based on steam production, Bleed on the ratio of make-up & bleed volume…
YOU NEED TO ADD ANOTHER PH, ORP, BOILER CONDUCTIVITY…
Upgrade kits can expand the controller to 14 analog sensors,
10 watermeter-digital inputs and 10 Relay controls
The controller recognizes new sensor drivers and auto-configures.
The digital inputs can be switched between water meter inputs to contact closure inputs.
THE REST OF SECTION 3.
Not all of the following sections apply to your controller or application.
You may need some of these functions as your application evolves.
