The operation and interval time of POA are controlled by PLC.
POA is actuated by pneumatic and controlled by a solenoid valve, which could be an ON/OFF switch. The input pneumatic pressure determines the output pressure. Oil discharges during operation.
Recommend using input pneumatic pressure of 3.5~7 kgf/cm2 and setting up a solenoid valve’s ON/OFF time of more than 5 seconds for discharging oil.
POA has a feed-oil button which can be used for manual oil feeding.
Recommend working with OC type oil-air volume distributors to deliver the metered quantity of oil-air mixture to lubrication points.
POA has two pressure gauges that enable the user to check the input pneumatic and output operating pressure easily.
POA has a NC contact float switch that detects the oil level automatically and sends signals when the oil level is low.
POA has three NC Contact socket pressure switches, and the specifications are as follows.(1) High Oil-Pressure Switch sets 20 kgf/cm2 to detect the operating pressure.(2) Low Oil-Pressure Switch sets 1 kgf/cm2 to detect the pressure-relief function.(3) Air-Pressure Switch sets 3.5 kgf/cm2 to detect the pneumatic pressure.
