Compatible with Most New or Existing Murphy SWICHGAGE® Monitoring
Advanced, Rugged, Reliable Microprocessor Based Design
Built-in Crank Disconnect and Overspeed Switch
First-out Shutdown LED
The ASM150 is a user friendly, solid-state, automatic engine
controller. It provides basic automatic start/stop capabilities plus
other features found on more sophisticated and expensive controllers.
The ASM150 operates from 12 or 24 volt battery. It includes features
such as selectable crank and rest cycles, sensing circuit for crank
disconnect and overspeed, overcrank, and recrank protection on false
starts. Four LEDs indicate first-out shutdown for: low pressure, high
temperature, overcrank and overspeed. A fifth LED indicates engine
Advanced microprocessor circuitry gives the ASM150 high reliability and flexibility.
The ASM150 is compact and housed in a corrosion-resistant case. It
mounts flush in a panel and requires very little room. Ideal for small
generator or engine panels.
