FCI WATERMAKERS, INC. 91 Operational Instructions
RUN SEQUENCE
During the Run Sequence, if equipped with APC, the High Pressure Control Valve will
stabilize once the desired production rate is achieved. If not equipped with APC, the High
Pressure Valve should be set to where you are making your production rate. The unit’s
production rate can be found in the info section under the contact screen. The system
will wait for a given time period to allow the TDS sensor to verify the PPM reading.
When the system is in Run Sequence and stabilizing:
LPP – is on
HPP – is on
FWF Valve
– is closed
Quality Valve
– directed overboard
APC (if equipped)
– is stabilizing
When the time period has expired, the system will verify the PPM reading. If the PPM
reading is below the Product Quality Setpoint for ten seconds, the Quality Valve will
divert to the product water tank. If the PPM reading is above the setpoint for more than
sixty seconds, you will get a High TDS Alarm. If the PPM reading continues to stay above
the setpoint for the set High TDS Shutdown Time (amount of time set by the operator),
the system will shut down with a High TDS Shutdown. If at any point during the
production the water quality goes above the setpoint, the Quality Valve will immediately
divert back to overboard until the Product TDS sensor is able to get a reading below the
setpoint for ten seconds. At this point the system will divert back to the product tank.
When the system is in Run Sequence and stabilized:
LPP
– is on
HPP – is on
FWF Valve – is closed
Quality Valve – directed to product tank
APC (if equipped) – is stabilized
