Calculated Function:
When the AquaPro is configured with two sensors on s that use the same units of
measure, this “Math Channel” can be setup to derive a calculated measurement. Currently the pH and
conductivity measurements are the only ones that can use this feature.
Map the channels to be used into the variables X and Y. Then select the math function. Once this is setup a
calculated measurement will appear in the main measure display screens and current outputs and relays can be
driven by this function. (Refer to page 36)
Relays:
There are three standard relays in the AquaPro. Three additional relays can also be installed for a total
of six relays. The standard relays are designated A through C. The add-on relays are D through F. All relays are
Form C with normally open and normally close contacts. Choosing the correct contact is necessary to achieve
the desired action.
Each relay in the system can be driven by any measurement parameter in the system.
Additionally, each relay can be configured to operate as follows:
Disabled:
Relay will not activate. This means that the normally open contact remains open and the
normally closed contact remains closed.
Alarm:
Set low and high alarm values, low and high deadband values, on and off delay values.
Control:
Set Phase, Setpoint, Deadband, on delay, off delay and Overfeed timer.
Wash:
Set Interval and duration with off-delay timer.
Error:
Activate the relays when the assigned measurement is in an error state (EG: open temperature or
out of calibration)
Data Logging:
Setup the channels to be logged and setup the interval of data recording. When the log is full, set
it up to start over or stop until removed.
Language:
The AquaPro can be setup with the following languages:
English
Spanish
German
French
Italian
Portuguese
Chinese
Factory Defaults:
The AquaPro can be put in its original factory setup. Please be careful when using this
command and be sure that functions currently configured are not being used on control.
Time/Date:
Setup the time and date for data logging.
Passwords:
Passwords can be setup to protect system settings and calibration settings. The factory default
setup is to disable passwords.
