This ASCO Series 185 Power Transfer Switch automatically transfers single phase loads up to 100A. The automatic transfer switch senses the loss of utility power and signals the generator to start and restore power to your home or business – even if no one is home. When utility power has been restored, the Series 185 Transfer Switch automatically transfers your vital loads back to the utility and shuts the generator down.

  • Terminals for convenient connection of neutral and ground conductors.
  • Suitable for controlling standby generators with 2-wire automatic starting circuits
  • Available in NEMA Type 1 Indoor (steel) and Type 3R Outdoor (aluminum) enclosures, with hinged door designs.

CONTROL FEATURES

Push Buttons

On the front control display are three push buttons that control the operation of the generator and the ATS:

  • Transfer Test: Use this button to test the system. This operation starts the generator and transfers the load. Be sure that conditions are safe to do this operation.
  • Bypass Time Delay: Use this button to cancel the active time delay or exercise period (stops the generator after cooldown).
  • Set Engine Exerciser: Use this button to set the automatic generator exerciser.New/Advanced TSC 9 Series Transfer Controller with features specifically designed for Residential and Light Commercial ATS applications. User programmable timers, Simple LED interface.

Indicator Lights

On the front control display are five lights that indicate the status of the sources and the ATS:

  • Utility Acceptable: This light indicates that the utility voltage is acceptable for connection to the load.
  • Generator Acceptable: This light indicates that the generator voltage is acceptable for connection to the load.
  • Load on Utility: This light indicates that the generator voltage is acceptable for connection to the load.
  • Load on Generator: This light indicates that the generator voltage is acceptable for connection to the load.
  • Automatic Generator Exerciser: When the utility is acceptable and the load is on the utility, this light flashes the number of days until the next exercise period. When it is off, no exerciser period is set. The light is also off when the generator is running.

Time Delays

  • Adjustable 1 or 3 second time delay for overriding momentary utility source disruptions
  • Fixed 4 second time delay while on standby source to ignore momentary generator voltage dips
  • Fixed 5 minute time delay before load retransfer back to utility source, to ensure stability of utility power
  • Adjustable 2 or 5 minute unloaded running time delay allows generator to cool down prior to shutdown
