02250050-761 Supervisor Supervisor 1E 02250050-761 Compressor Controller



  • 02250050-761 Sullair Supervisor 1E -P/N 02250050-761 Compressor Controller


    The SullairSupervisor 1E P/N 02250050-761 supercedes the Sullair Supervisor 1 - P/N 02250081-361 which replaced the standard Electro-Mechanical controller of pushbuttons switches and gauges.

     The SullairSupervisor 1E - P/N 02250050-761 control panel consists of displays for pressure,temperature, time (run hours) and a status message. The default pressuredisplayed is line pressure (line pressure) with touchpad selections for sumppressure, fluid pressure, separator differential and fluid filter differential.The default temperature displayed is unit discharge temperature (T1) withtouchpad selection for injection fluid temperature. LEDs provide a graphicillustration of the points being monitored.






    Operatorcontrols consist of EMERGENCY STOP, ON/OFF, monitor display pads andprogramming pads. All compressor control, pressure and temperature displays areprovided in the Supervisor 1E - P/N 02250050-761.






    • The line(terminal) pressure transducer (P2) is connected to the dry side of thereceiver downstream from the check and continually monitors the plant airpressure.
    • The sumppressure transducer (P1) monitors the sump/unit discharge pressure.
    • Injectionoil pressure (P3) monitors oil pressure at the point of injection into thecompressor downstream of the oil filter.
    • Filter oil pressure (P4) monitorsoil pressure ahead of the oil filter and is used with P3 to calculate oildifferential: P2 = P4 - P3.
    • The discharge temperatureprobe (T1) monitors the temperature of the air leaving the compressor unit. Forboth air cooled and water cooled compressors the normal reading isapproximately 180 ºF (82 ºC) based on 80 ºF (27ºC) ambient temperature.
    • The injection temperature probe (T2)monitors the temperature of the fluid just before it is injected into the unit.
    • The air filter maintenance switchmonitors the condition of the air intake filter. When the Supervisor displaysthe message AIR FILTER MAINT RQD, filter service is required.
    • The ON/OFF pad turns the compressoron and off.
