Status: AUTO MAX
Indicates that the Inlet Pressure is not Low, and the controller is waiting
for a Flush cycle to begin. The system is assumed to be in normal filtra-
tion mode and flowing water. The Flush interval timer is running. The
controller displays Status: AUTO MAX when the Inlet Pressure in not
low and a Flush cycle has not begun. A Flush can occur from the Timer,
a high pressure differential via the Pressure Transducers, indicated as
>> High PSID << on the display, manually by the operator by pressing
the green OK button on the controller, or by the Customer Input Signal.
Status: ON MAX
Indicates that the system is in a Flush cycle, initiated either by the Oper-
ator, by the Flush Interval Timer, the Pressure Transducers, or by the
Customer Input Signal. The controller will stop displaying the PSID val-
ue, but will instead indicate Flush Cycle.
The Flush Valve is opened, and the Alarm Light/Sounder output is flash-
ing. This output flashes the Light and Sounder throughout the entire
Flush cycle. The Flush Duration is nominally set for 8 seconds. The Flush
Duration time is adjustable
- see Setup screen #3 for information.
After this Flush duration time, the Flush Cycle is complete. The Open
Flush Valve Output will be turned off, the Alarm Light/Sounder will be
turned off, and the Status Screen will display Status: AUTO MAX.
Status: System Alarm
On any of the status screens, a System Alarm screen can be activated.
The second line down will be alternately flashing >> System Alarm <<
and whatever was on line 2 before the system alarm occurred.
A system alarm can be any customer specific alarm. The only standard
system alarm is the Consecutive Flush Alarm. This alarm occurs when
the Flush cycle has been initiated three times in a row by the Pressure
Transducers (PSID). Output #4 will be turned ON, which will then ener-
gize Relay 1 (R
- 1). Relay 1 provides a Dry Contact signal for the Custom-
er ’ s Consecutive Flush Alarm monitoring.
The Consecutive Flush Alarm will also cause the Alarm Light/Sounder to
change from flashing to steady ON. The Consecutive Flush Alarm will
also disable any additional Flush Cycles from occurring.
