Description
The ASM150 is a solid-state, automatic engine controller with automatic
start/stop capabilities.
The ASM150 operates from a 12 or 24 volt battery. It includes selectable
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 and overspeed. A
fifth LED indicates engine running.
The ASM150 mounts flush in a panel and is ideal for small generator or
engine panels.

Mounting the ASM150 Module
1.
To mount the ASM150 module to your panel or wall, drill five (0.250 in.
[6 mm] dia.) holes for LED indicators, and two (0.203 in. [5 mm] dia.) holes for
mounting screws. See “Mounting Drill Pattern”, above, for dimensions.
2.
Insert the ASM150 module from the back of the panel or wall into the pre-drilled
holes. See schematic below.
3.
Remove the adhesive cover from the back of the ASM150 label and position the
label on the panel or wall–press firmly.
Make sure the panel is clean
and free of oil.
4.
Secure the label and module
in place with the two
screws provided.
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 there-
fore, recommended that monitored functions be limited to
alarm only or to alarm before shutdown in such applications.
