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
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.
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:
Air Damper Shutoff
Power Input: 6 to 28 VDC.
Power Consumption Standby: <1 mA.
Operating Temperature: -40 to 185 °F (-40 to +85 °C).
Inputs: Ground or positive inputs for high temperature, low oil pressure, High/Low Level, Auxiliary/Remote Stop sensors.
Lamp Test: When unit is powered up in Manual or Auto, the LEDs light for 1 second as a test.
Outputs: 5A smart FET for cranking and multifunction
output. 10A smart FET for Fuel Valve (Energized to Run) output. All 3
supply battery +. 125 mA transistor for common failure, engine run,
and auxiliary output. (Sink to battery )
Crank Attempts: Selectable for 3, 5, 10, or 255.
Crank/Rest Cycle Timing: Field adjustable 1 to 30 seconds.
Multifunction Output: Field programmable to one of
the following options: Glowplug, Cooldown, Warmup/Cooldown, Warmup, Air
gate Overspeed Only, Air gate Always, Choke, or Auxiliary Run
Shutdown Lockout Time Delay: Field adjustable 1 to 300 seconds. Locks out low oil pressure, high temperature, and loss of speed shutdowns on start-up.
Crank Disconnect Speed Setting: From 13 to 2500 Hz.
Overspeed Trip Point Setting: From 13 to 8500 Hz.
Speed Sensing Input: 1.5VAC RMS to 140 VAC RMS.
Shipping Weight: 1 lb. (.45 kg.)
