Operation 3-5Part 106913ā04 2018 Nordson CorporationRotary Sieve SettingsNOTE: Sieve operation depends on system configuration. The sieve willturn on when the exhaust fan is started, or automatically on a signal fromthe feed-hopper level sensor.1. See Figure 3-4. If your system uses a rotary sieve equipped with apneumatic panel set the bearing-air pressure regulator (3) andflowmeters (1):Bearing air pressure 1.7 bar (25 psi)Flow meters 100 SCFH2. If your system uses an air-operated vibratory sieve, set the motor airpressure to 3 bar (50 psi). Increase or decrease the pressure asneeded to maintain the flow of powder through the sieve.Final Startup Steps1. Set the accumulator vent-assist air pressure regulator (2). Refer toVent-Assist Air Pressure Adjustment on page 3-8.2. Set the transfer-pump air pressure to 1 bar (15 psi). Set thetransfer-pump selector switch to AUTO. This turns the pumps on and offon a signal from the feed-hopper level sensor.3. Set the conveyor interlock switch to NORM.12 31Figure 3-4 Sieve Air Pressure Regulators and Flowmeters1. Flow meters2.
