SECTION 1 : INTRODUCTION
The ECU-04 Generator Auto Start Control, simply
changes any manual key start generator to auto-start
by automatically mimicking the action taken by
someone turning the panel key and starting the
generator manually.
The ECU-04 automatic initiation of the generators
starting cycle by using the standard two-wire signals
from any Automatic Transfer Switch or any standard
remote mounted ON / OFF switch.
In case of generator starting failures, this device has
maximum of 3 attempts of preheat and start with
adjustable time form1 to 25 seconds interval.
This module is composed of microprocessors to
minimized dimension. Encapsulated in factory
designed chassis to protect them from vibration and
moisture.
SECTION 2 : STANDARD FEATURES
●Small size, low cost, low power consumption and
easy to install.
●Connected by the terminal block. Easy for
installation and repairing.
●A single chip microprocessor is utilized.
●Epoxy encapsulation makes the ECU-04
dependable and reliability.
●Multi-start function. (The factory setting is 3 times.
The different Value from customer's request is
acceptable.)
NOTE
Don’t release the battery when engine is running.
Never feed charge motor voltage directly into
controller, to prevent damage to the controller
caused by high charge voltage.
