●Auto Mode ( )
 After pressing and holding button for at least one second, the indicator next
to the button will be illuminated and the module will be placed into its automatic
mode. If remote start signal is active (remote start input port is connected to B-),
after start delay the genset will start. Preheating output will be activated firstlyand
preheat delay begins. One second before it is finished, fuel output will be
activated for one second and after that preheat output will be deactivated; then
starter is energized to output (engine will try to start according to the pre-set
number of times; if one of the attempts is successful, the start process will be
completed, otherwise fail to start alarm will be initiated: fail to start indicator on the
panel will be illuminated and common alarm indicator will flash). After start delay
and idle delay, idle relay will be deactivated and the generator will start working at
normal speed.
Note: During crank rest time, fuel output is deactivated; three seconds after the
beginning of the delay, preheat and ETS outputs will be activated; after the end
of the delay, ETS output will be deactivated and fuel relay output; preheat output
will be deactivated before the beginning of crank.
 When remote start signal is deactivated, after stop delay, the generator enters idle
state and the idle relay is deactivated. After idle delay, fuel relay deactivates, ETS
relay output activates, and the genset automatically stops. After complete stop,
ETS relay deactivates.
●Stop ( )
 After pressing and holding for at least one second during normaloperation of
the genset (in manual or auto modes), the light indicator near the button will be
illuminated and idle operation will begin. When idle relay deactivates and after idle
delay, fuel relay is deactivated and ETS output is energized. When complete stop
of the generator, ETS isdeactivated.
 In case of fault alarm, pressing and holding the button for one second willclear
alarms. Holding it for more than one second will illuminate all indicators on the
panel (light test function).
 Pressing this button for more than one second in stop mode will lead to activation
of ETS output and illumination of all the indicators on the panel (light test function).
Releasing the button will immediately deactivate ETS output and light test
function.

 When in stop mode, the module will only react to emergency stopsignal.
Note: Configurable output ports can be set as one of the following functions: “ETS
output”, “Idle output” or “Preheat output” via PC. Therefore, all three functions can
not be active at the same time; the above-mentioned is only to describe the logical
course of action of the controller in case all three functions are active.

7. PARAMETER SETTING
1) Pressing and simultaneously in generator standby mode will lead to the
password interface (as shown below); when the first digit is blinking, enter the
password 0318;
2) Press button to increase the value of the blinking digit and to decrease
the value; when the first digit is set, press to move thecursor;
3) Repeat the same procedure to set the digits from 2nd to 4th;
4) If the password is right, enter into the parameter configuration interface (as shown
below) which including the serial number of the set items and their parameters;
press to scroll up and to scroll down;
5) Press to set the current item, and when the first digit starts blinking, use the
same way that is used for password to enter the setvalue.
Password: Parameter Setting:
Attention:
1) Please change the controller parameters when generator is in standby mode only (e.
g. Crank disconnect conditions selection, configurable input, configurable output,
various delay), otherwise, shutdown and other abnormal conditions may happen.
2) The value of each parameter can be set only within a certainrange.
3) Over voltage set value must be higher than under voltage set value, otherwise
over voltage and under voltage condition may occur simultaneously.
4) Over speed set value must be higher than under speed set value, otherwise over
speed and under speed condition may occursimultaneously.
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 crank disconnect.
6) Consult the table 1 for serial numbers of theparameters.
7) Before selecting fuel level sensor type, it is necessary to set a configurable input
port type as 0.

﹡Remark 1: Pressing button during parameter setting will immediately exit the
set parameter.
﹡Remark 2: If the generator is in manual mode and crank disconnect condition is set
as 2 (magnetic pickup + generator frequency) or 5 (generator frequency +
magnetic pickup + oil pressure) and generator frequency and speed are NOT
equal to zero, pressing and holding and for 0.5 seconds will lead to the
controller automatically adjusting the flywheel teeth number according to
generator frequency and generator poles number.
