DESCRIPTION

The ASM170 is a compact yet powerful engine auto-start module. It offers flexibility and features normally found in much larger and more expensive units. Its high density MOLEX plug makes it ideal for panel builders. It can also be easily replaced in the field if problems should arise.

 

With the on-board Manual-Off-Automatic switch, Panel wiring is greatly simplified.

 

Its unique design also allows it to draw virtually no current in standby mode, yet be able to auto-start based on a sustained or momentary contact closure.

 

FEATURES

 

The ASM170 is typically used in generator applications but can be applied anywhere a basic auto-start operation is required. Basic functions include engine crank/rest, crank disconnect, overspeed, low oil pressure, high engine temperature, low levels and spare shutdowns. The start signal to the controller can be momentary or sustained.

 

It also has a multifunction output that can be selected to perform one of the following functions:

  • Glowplug
  • Warmup/Cooldown
  • Warmup
  • Cooldown
  • Choke
  • Air damper shutoff
