Description
The ASM160 is an engine controller with automatic start/stop, and selectable
warmup/cooldown or glowplug capabilities.
The ASM160 operates from a 12 or 24 volt battery. It includes crank and rest
cycles, sensing circuit for crank disconnect and overspeed, overcrank, and re-
crank protection on false starts. Four LEDs indicate first-out shutdown for:
Low Oil Pressure, High Temperature, Overcrank, Overspeed. A fifth LED
indicates Engine Running. There are also two (2) spare inputs that will cause
the unit to shut down without annunciation on the front LED’s.

Installation and Operation Instructions
Please read the following information before installing. A visual inspection of this product for damage
from shipping is recommended before installing. It is your responsibility to have a qualified person install
this unit and make sure it conforms to local codes.
GENERAL INFORMATION
Mounting the ASM160 Module
1.
To mount the ASM160 module to a panel, drill five (0.250 in. [6 mm] dia.) holes
for LED indicators and four (0.203 in. [5 mm] dia.) holes for the mounting
screws. See “Mounting Drill Pattern”, above, for dimensions.
2.
Insert the ASM160 module from the back of the panel into the pre-drilled holes.
See schematic below.
3.
Secure the module in place with the four mounting screws provided.
4.
Make sure the panel is clean and free of oil. Remove the adhesive cover from the
back of the ASM160 label. Position the label
on the panel and press firmly.
