Basic Functions
Power Recovery- If the power fails the system will automatically reboot, and continue its operation
upon the return of the supply power. No user settings will be lost. No Alarm History will be lost.
The User Interface- The user interface has been constructed to allow soft touch screen button use as
well as Fkeys to minimize the operator's interaction requirements. Refer to Screens for further
information.
Multiple Language Ability- The user interface was constructed to allow multiple languages as
selected in the set up screens. The Initial and Set Up screens will always be shown in English no
matter what language is chosen.
Conductivity- The conductivity of the system is monitored continuously with the use of the supplied
Toroidal conductivity probe placed in a continuous water flow on the filtration skid that bypasses the
filter. Allows for control of conductivity based blow down as well as HI and LO alarms placed around
the normal conductivity levels. Functions have been added to allow the calibration of the conductivity
sensor to AIR as well as to a higher known conductivity value liquid.
Blow Down Control- The blow down is controlled by a blow down set point that is selectable within
the user screens. The blow down utilizes the conductivity valve against the selected blow down
settings to control and maintain the conductivity within the system water. A dead band (found within
the Set Up screens) is utilized to reduce valve opening and closing frequency to lengthen valve life. A
simple test has been added to the Bleed screen that allows for the easy verification of Blow Down
Valve operation.
Filter Control- The filters are monitored continuously and their cleaning routines are controlled by
the Control Station. The number of back washes are shown on the main screen for easy viewing. A
Manual Back Wash initiate feature has been added to the main screen to allow your testing of the back
wash ability of the filter. The filter control interfaces with a differential pressure switch (DP) as well as
the back flush solenoids to aid in the control and monitoring of the filter.
Pump Monitoring- The control station can be configured to monitor the power system of the pump,
this includes the power status of the pump, its thermal overload condition as well as monitor the Power
Phase condition of incoming power. The system can be configured to monitor the pump's pressure if
required.
Alarm Indication- Alerts are shown under their corresponding labels, the alarms have been prioritized
to minimize nuisance alarms. Upon an alarm activation, an output of the controller can be utilized to
send a 24VDC signal to an indicator for the customer's use.
Alarm Storage- As alarms occur, they are stored in the control station's memory for future use. They
can also be stored continuously onto a Micro SD memory card if it is installed in the controller.
Optional Features- As shown above many of the monitoring features of the pumps can be turned ON
and OFF as required. The station also has the ability to communicate in other ways with building
control systems and other communication systems, contact EcoWater CHC for further information
about the communication abilities.
Set UP Screens- The Set up screens contain the basic system settings needed to configure the
operation of the system.
Password Protection- All sensitive configurations of the system have been password protected. From
the initial Start Up screen, you can press the SET UP button that will change the screen to the Password
screen. As the appropriate password is entered and the Enter (F3) button is then pressed the system
will conduct several possible items. These items could be entering into the Set UP screens (password
5850) or Conducting a Factory Default on all system settings (password 8789), clearing the counter
memories (password 1000), or simply restoring the user setting to User Defaults (passwords 112 or
977). If any of the defaults are completed all counter memory is reset to 0. This means that the back
wash counts, secondary back wash counts, current conductivity calibration, ect will be lost.
