• Autodual Simplex Lead/Lag Controller
  Simplex controller runs two compressors in Lead/Lag mode with ONE Autodual controller. No control connection required between units. Ideal solution for Intellysis or "T" control units. Incorporates full Autodual functionality on second compressor only, yet gives lead/lag functionality to both compressors. Manual and full automatic/manual switching available.

Safety

• Emergency Shutdown
  External 6' Power cord connects to any non-powered normally closed (N.C.) emergency shutdown device, i.e., low oil pressure, low oil level, high air temperature, power line monitors, starter overload, or any of the above combinations. Failure of any of the above shuts the compressor motor down 20 seconds after receiving fault signal, activating flashing light on the Universal AutoDual.
• Remote Shutdown Signal
  Sends a remote fault signal (24VDC, 40ma) from AutoDual to a control room sensor, or auxiliary remote audible or visual alarm.
• Oil Pressure Switch
  Din Mounted Low Oil pressure switch (10 P.S.I) triggers AutoDual Emergency Shutdown feature in low oil pressure condition.

Automatic Tank Maintenance

• Timed Tank Drain
  Activates tank mounted solenoid drain for 5 seconds for every hour of compressor pumping time. Motor idle time does not affect the drain timer, saving energy and wasted air. Includes 6' Power cord to tank drain solenoid and Console mounted manual drain (test drain) button. Solenoid tank drain offered below.
• Drain Duration Control
  User selectable Drain "purge time". Adjustable for 5, 10, or 20 second drain duration. Longer drain duration time used in high humidity environments. Front panel user Selectable switch.
