108MM 15-50hP VFD MPC CONTROL SYSTEM (FULL LOAD) R00
After the initial start-up and the load delay has expired, the solenoid valve will shut off the blowdown circuit,
allowing the sump pressure to come up to operating pressure. During this time, no control air will be flowing
to any major components. As the sump pressure reaches the set point of the minimum pressure valve, air
flow to customer’s process will start. The outlet pressure to the customer’s process is monitored and will
control the blowdown when needed. Sump pressure and line pressure are displayed on the control panel to
visually monitor the status of the compressor. Until the customer’s process achieves the set pressure, the
compressor will run in the full-load condition.
