Murphy ASM170 User Manual

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-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.

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

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.

How to Order:

CAUTION:

Certain danger to human and to equipment
such as applied in a mobile or marine application may occur
if some equipment is stopped without pre-warning. It is
therefore, recommended that monitored functions be limited

to alarm only or to alarm before shutdown in such applications.
