The feed pump will continue to run autonomously until
“Stop” is pushed on HMI, if H-O-A is
switch to the
“Off” position, or if E-Stop Button is pressed on either HMI panel or PLC Control
Panel.
In Extraction mode and if the Residue and Ethanol H-O-A are in Auto then holding storage will
automatically be pumped down until Low Switch is off. At this point it will wait until it is called
again with the High-level Switch. Reference Speed of each pump will automatically ramp up
depending on High Level Switch that is made up. System will check every 5 sec if a ramp up is
needed depending on state of high- level switch. If high switch is still made up after 5 sec check
then ramp will initiate for 5 sec, then re-check level status. If high switch is no longer made up
after re-check than system will continue to pump down at that speed until level is below Low
Switch. Each Pump is controlled by their corresponding Level Switches (Note** Residue
Switches are Ultrasonic Level Switches different from Ethanol Switches which are Float-Style
switches).
Automatic operation of all three pumps can be stopped by switching H-O-A to the
“Off” Position.
When transitioning to Recycle Mode upon changing mode the system will lockout for 20 sec to
give the valve enough time to actuate and change direction of flow. A
“Valve in Motion” will appear
until system is done actuating. After
“Start” button can be initiated to Run Feed Pump in Reverse
Direction at the Speed command setpoint
“Rec. Speed Hz” located on the Pump Control
Screen. The system will run and pump the fluid out the Feed until Pre-heater pressure reaches
“Rec. Stop PSI” setpoint. Once system stops it can be changed back to extraction mode for
normal operation after Valve reposition delay.
