Description

Specifications

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-OffAutomatic 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.

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 LED’s 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 output.

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

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.)
Shipping Dimensions:
6.25 x 6.25 x 4.5 in.
(159 x 159 x 114 mm).

For the OEM
The ASM170 was designed with the
OEM in mind. Each unit comes standard
with a programming header easily
accessible from the rear of the unit.
Through this header, the OEM can
upload specific operating parameters
normally controlled with the DIP switch
and Potentiometers directly into the
controller. This way the exact settings
required by the OEM will be
programmed and the DIP switch and
Potentiometer settings will be ignored.
