Description
The EA150 Automatic Engine Controller
provides you with simple–yet sophisticated,
engine automation. It features basic auto-
matic start/stop capabilities plus other fea-
tures found on more sophisticated and
expensive controllers–all in an easy to
install panel.
The EA150 operates from 12 or 24 volt sys-
tems. It includes crank and rest cycles, sens-
ing circuit for crank disconnect and over-
speed, overcrank, and re-crank on false starts.
Four LEDs indicate first-out shutdown for:
low pressure, high temperature, overcrank
and overspeed. A fifth LED for engine run-
ning indicates when crank disconnect occurs.
The built-in oil pressure and water tempera-
ture SWICHGAGE
® instruments provide visu-
al indication and can be set to initiate shut-
down on critical pressure and temperature.
The electromechanical quartz base hourme-
ter can record up to 9,999.9 hours. It is
housed in a shockproof case and built to be
rugged and durable for a long life.
A selector switch allows you to manually
select the operation sequence.
