System Operation
Series S50 RO System Controller Operation
The unit has a single mode of operation ON with 6 sub-modes or states as indicated by the steady or flashing panel lights.
Any light condition other than steady Power ON indicates the unit is effectively in stand-by. If there are no lights – system
is OFF and all outputs are turned off. In the operating mode, the unit operates automatically. All inputs are monitored, and
the outputs are controlled accordingly. Pressing the Power key will toggle the unit from off to operate or from operate to
off. If power is removed from the unit, when power is reapplied, the unit will restart in the mode it was in when power was
removed.
Illustration 8 - Controller Sub-Modes
Power Key:

Pressure Retry:
Steady red light.
Pressure fault:
Flashing red light.
Power On:
Steady green light. System operating.
Pretreat:
Flashing green light.
Tank Full:
Steady amber light.
Flush:
There is no Flush sequence.
When the power switch is turned ON, the center status LED will light Green, the inlet valve will OPEN and the RO pump
will START. (Refer also to Switch - pages 12.)
Under normal operation the RO unit will run until: (A) the storage tank is full (right LED Amber) or (B) Pretreat lockout has
occurred (center status LED Flashing Green). When A or B has cleared, after a time delay, the RO unit will restart, and
the center status LED will return to Green. Switch setting 3 selects a 2 second- or 15-minute tank full restart time delay.
Upon an alarm signal for Pressure Fault, the left status LED will Flash Red, the RO pump will stop and the inlet valve will
close and the RO pump will turn OFF.
If switch 1 and 2 are in the OFF Position (disabled), the left status LED will be a steady RED and the RO will not restart
until the Power Switch has been manually cycled OFF then ON to reset the unit. If switch 1 is in the ON Position (auto
reset), every 60 minutes the RO will start and stop again if a pressure fault continues.
If switch 2 is in the ON Position (pressure fault retry), the RO will attempt to restart after 30 seconds, then 5 minutes, then
30 minutes. If the pressure alarm has not cleared after the third try, the RO unit will remain off until manually reset.
If switch 1 and 2 are in the ON Position, after a pressure fault condition, the RO unit will continually attempt to restart after
each 60-minute cycle, until the pressure switch input has cleared.
