5.4.1. Man Start
When push Man start button ,preheat will first output, and start preheat delay, when preheat
delay is end, fuel output 1 second, preheat output will stop, and crank output is start.Here engine
will start, when crank successfully, crank output stop. Then engine comes into the safe time. When
the safe time is end, then engine comes into the idle time. When the safe time is end, then idle
output is out and engine will run at full tilt.
5.4.2. Auto State
When push button, the module will enter automatic state. Here if remote start input is
active (connect to B-), the engine will start after the delay of start engine. Preheat will first
output, and start preheat delay, when preheat delay is end, fuel output 1 second, preheat
output will stop, and crank output is start. Here engine will start, when crank successfully,
crank output stop. Then engine enter the safe delay. When the safe delay is end, then
engine enter the idle delay. When the safe delay is end, then idle relay is close and genset
raise high speed.
When remote start input is inactive, the engine enter the idle process after the delay of
engine stop, idle relay disconnect, fuel relays output after the idle delay, ETS solenoid output,
genset will automatically stop, ETS solenoid disconnect when genset stop steady.

NOTE: During the starting delay period, the fuel output disconnect. 3 seconds after entering
the starting delay process, pre-heat and ETS output.After the end of the starting delay period,
ETS output disconnect. Fuel output and pre-heat output disconnect before starting.
5.4.3. Stop State
Push the button when engine is running, the button beside led will lighten, enter idle
process, idle relay disconnect, idle delay ended, fuel disconnect, ETS solenoid output,
genset stop, ETS solenoid disconnect when genset stop steady.
When engine is waiting state, push button 1 second above, ETS solenoid will output and all
led will be Lighten. Loosen the stop buttons, ETS solenoid output disconnect instantly, and
test lamps function is over.
When engine is waiting state, only emergent stop alarm can be check.
6. ALARM
Low Oil Pressure: check after the safe delay, the duration of 5 seconds above, the module
will alarm and stop engine.
High Temperature：check after the safe delay, the duration of 10 seconds above, the
module will alarm and stop engine.
Low Fuel Level: When the fuel level is consistently below the preset value of 10 seconds,
and issuing fuel level is too low signal, this value is only a warning will not stop.
Over speed: check after the preheat delay, the duration of 2 seconds above, the module will
alarm and stop engine.
Under speed: check when engine run at full tilt, the duration of 15 seconds above, the
module will alarm and stop engine.
Over Crank: when engine crank fail over the times of configure, the module will alarm and
stop engine.
Stop Failure: when engine is stop fail, the module will warn.
Battery over voltage: The DC supply has risen above the high volts setting level for the
duration of the high battery volts 20 seconds.
Battery under voltage: The DC supply has low above the under volts setting level for the
duration of the low battery volts 20 seconds.

Emergency Stop: When emergency stop input, ETS solenoid stop immediately output, and
then fuel disconnect, preheat and start signal emit emergency stop alarm signal.
Gen Over Voltage: When the continuous sampling voltage higher than the preset value, at
the end of the abnormal delay, signal generator voltage is too high, outage alarm at the
same time.
Gen Under Voltage: When sampling the voltage is lower than the preset value continuously,
at the end of the abnormal delay signal generator voltage is too low, outage alarm at the
same time.
Gen Over Frequency: When the sampling frequency for 10 seconds after the signal
generator frequency is too high, outage alarm at the same time.
Gen Under Frequency: When the sampling frequency for 2 seconds after the signal
generator frequency is too low, outage alarm at the same time.
Common Alarm: when any alarm or warn is appear, this alarm will active. When the over
speed, under speed, high temperature, low oil pressure, emergency stop, no generator,
crank failure, stop failure alarm, battery over voltage, battery under voltage, common alarm
LED illuminate, and common alarm output.

8. CONDITIONS OF CRANK DISCONNECT
Pictured above,select the desired options,can be selected or not selected
There are 4 conditions to make starter disconnected with engine,that is,speed sensor, generator
frequency ,Charge D + and engine oil pressure. They all can be used separately. We
recommend that engine oil pressure should be using with speed sensor and generator frequency
together, in order to make the starter motor is separated with engine immediately and can check
crank disconnect exactly.
Speed sensor is the magnetic equipment which be installed in starter for detecting flywheel teeth.
When set as speed sensor, must ensure that the number of flywheel teeth is as same as setting,
otherwise,“over speed stop”or“under speed stop”may be caused.
If genset without speed sensor, please don’t select corresponding items, otherwise, “start
fail”or“loss speed signal”maybe caused.
If genset without oil pressure sensor, please don’t select corresponding items.
If not select generator in crank disconnect setting, controller will not collect and display the
relative power quantity (can be used in water pump set);if not select speed sensor in crank
disconnect setting, the rotating speed displayed in controller is calculated by generator frequency
and number of poles.
If the generator without magnetoelectric sensor and Oil pressure sensor,the“Charger D+”is
optional as a starter motor separation conditions.It is recommended to select“Oil Pressure+
Charger D+”for safety.
9. PARAMETERS SETTING
1) The controller in standby mode simultaneously press the and ,entering the
password input interface ( following figure), When the first digit flashing, enter the password
0000;
2) press the numerical plus 1, press the Numerical minus 1, Set the correct numerical
value press the change;
3) Set the second bit to fourth bit digital in accordance with the above method;
4) If the input the correct password to enter parameter setting interface (following figure), Displays
the current settings of the serial number and parameter, press the set options flip up, press
the set options flip down;

5) press the enter the parameter setting state, the first digit flashing, set of numerical methods
with the same password input method.
Password input interface：Parameter Settings interface：
Matters needing attention：
1) Please change the controller parameters when generator is in standby mode only (e. g. Crank
disconnect conditions selection, digital input, digital output, various delay), otherwise, shutdown
and other abnormal conditions may occurs.
2)When set each parameter, must be within the allowed range, otherwise will not be able to change
the parameters.
3) Over voltage set value must be higher than under voltage set value, otherwise the controller will
not save the data.
4)Over speed set value must be higher than under speed set value, otherwise the controller will not
save the data.
5) Please set the generator frequency value as low as possible when cranking, in order to make the
starter be separated quickly as soon as possible.
6)Set the serial number with reference to the front “7.1 Parameter setting list (Table I)”.
7)In setting fuel level sensor type when, the programmable output type is set to 0, set the fuel level
sensor type again.
﹡NOTE 1：In the process of setting up, any time button will interrupt parameter settings.
﹡NOTE 2：In manual mode, startup success condition configuration：(2 magnetic sensor+generate
electricity) or (5 generate electricity + magnetic sensor +oil pressure), power frequency
and speed is not zero, press the start button and flip keys at the same time (0.5s),
controller according to the power frequency and generator series automatic generator
teeth.
