2 FLSH Manual Flush
You can use this menu item to force the RO Controller to manual flush regardless of the condition of the
current flush process. Each time you enter a value, that value is used to operate the flush function. If the
RO is currently flushing, you can use this menu to terminate the flush. To stop a flush operation, select
this menu, adjust the value up and back down to zero and then advance to the next menu. The new value
of zero will be saved and the current flush will be canceled.
3 ond Motor ON Delay
This item is used to adjust the motor ON delay. When the RO controller detects a low product level, the
controller turns ON the inlet solenoid and then waits for the motor ON delay before turning ON the
motor. If a low supply pressure occurs, the motor ON delay will recycle.
4 oFFd Motor OFF Delay
This item is used to adjust the motor OFF delay. When the RO controller detects a high product level,
the controller waits for the duration of the motor OFF delay before turning OFF the motor. If a low
supply pressure occurs, the motor OFF delay will recycle. This OFF delay is used to de-bounce
momentary low pressure cycles before turning OFF the motor.
5 LP-A Low Supply Level or Pressure Alarm Setpoint
This item is used to shut down the RO system if multiple low supply pressure cycles occur. The value set
in this menu is the maximum number of low supply pressure cycles that can occur in a short period
without shutting down the RO system. If a longer period of time passes without a low supply pressure
cycle, the current low pressure count will be reset. Setting this value to zero will disable this function. A
low supply pressure shutdown is displayed by flashing the “Low Supply” and “Err” message on the
display.
6 Sr Service Reset Time
Once a shutdown has occurred due to a low pressure cycle, this timer is started and once it expires, the
shutdown condition will be reset. Under normal operating conditions, the supply water will only have a
temporary low pressure condition. This timer is used to reset the controller for normal operation again.
If the shutdown continues to repeat, you may have a problem with pre-filters or the supply connections.
7 FC Flush Cycle
This controller will perform a flush function on a regular cycle based on the setting of this timer. When
the power is first turned on, this timer starts at zero. Each time the RO is operating, this timer is enabled
to run. When the timer expires, a flush is started. The setting of this timer will produce a flush after the
set time of RO operation. If this timer is set to zero, no flush will be started.
8 Fd Flush Duration
Once the “Flush Cycle” timer has started a flush, the flush will run for the flush duration. Use this timer
to set the total amount of flush time your system requires. Setting this timer to zero will disable a flush from
occurring.
