SECTION 2 : PRODUCT OVERVIEW
The EC-05 Auto Start Module can accept signals from
a remote switch or an ATS to automatically start and
stop a gasoline engine generator and obtain remote
operation. It is suitable for key start gasoline engine
generator equipped with a starter motor but without
automatic start and stop function. The EC-05 control
module has choke control function making it especially
suitable for use in cold regions.
SECTION 3 : EXTERNAL WIRING AND
PRECAUTIONS
3.1 AC Input Terminals：Generator AC Power Input
Terminals. The controller cuts off the signal to the
starter motor when AC power frequency is
greater than 18 Hz.
Input Range：5 –305 Vac 50/60 Hz
Precautions：
The AC Power Input must come directly from the
generator and cannot be connected and
disconnected by a circuit-breaker. This is to avoid
possible improper operation caused by the
controller from loss of sensing of AC frequency
leading to repeated start attempts even if engine
is running.
3.2 B+ & B- Terminals：Battery positive (+) and
negtive (–) power input terminals.
Input Range：9 36 Vdc
Precautions：
The battery must not be disconnected when the
generator is running. This is to avoid the high
voltage output of charging alternator being fed
directly into the controller and damage it.
3.3 Start Terminal ：Starter motor signal output
terminal. Terminal output is the battery (+) of
DC12V / 24V when the engine is cranking.
3.4 Stop Terminal ：Engine stop signal output
terminal. During engine shutdown the terminal
output is the battery (). When the Stop timer
setting has been reached this terminal is
de-energized.
3.5 Choke Terminal：Choke Solenoid signal output
terminal. Terminal output is the battery (+) of
DC12V / 24V when the engine is cranking.
3.6 Remote Start Terminals：Engine Remote Start
Signal input terminals. When the contact is
closed the engine is running. When the contact is
open the engine is stopped.
Precautions：
The external remote start input must be a dry
contact without power. Inputting a DC or AC
signal may cause damage to the controller.
SECTION 4 : TIME DELAY AND FUNCTION
SETTINGS
4.1 Stop potentiometer：Stop action timer.
Setting range：1 20 secs. (stepless adjustment)
4.2 Choke potentiometer：Choke action timer.
Setting range：1 20 secs. (stepless adjustment)

4.3 Start potentiometer：Starter cranking timer
Setting range：1 10 secs. (stepless adjustment)
4.4 Time between start attempts：6 secs. (not
adjustable)
4.5 Engine start attempts：3 times (not adjustable)
SECTION 5 : LED STATUS INDICATORS
5.1 Engine Running Indicator LED (Green)
Flashing：Engine is in Standby mode
Illuminated：Engine is running
5.2 Engine Start Failure Indicator LED (Red)
When three engine cranking attempts have been
made but the engine will still not start normally
the Engine Start Failure indicator will illuminate,
indicating that the engine has failed to start.
Precaution：
If AC voltage input is lost when the genset is
running normally the Engine Running and Engine
Start Failure indicators will flash at the same time.
This indicates that the system has failed but the
controller will not stop the engine. This situation
could be caused by an AVR failure or poor
connection of the AC voltage input.
Do not allow a remote start input signal to attempt
start automatically before the fault is eliminated.
This is to avoid possible improper operation of
the controller caused by loss of sensing of AC
frequency leading to repeated start attempts
even if the engine is running.
