a)
There are 3 conditions to make starter separate with engine; speed, generator frequency and
oil pressure, and all of them can be used separately. It is recommended to use oil pressure and
speed cooperatively, for the purpose of disconnecting the starter motor as soon as possible.
b)
Speed means real rotation speed detected by the speed sensor. Speed sensor is the magnetic
equipment which is installed in starter for detecting flywheel teeth.
c)
In case speed is selected, it must be confirmed that the number of flywheel teeth is as same as
the setting, otherwise, "over speed shutdown" or "under speed shutdown" may be caused.
If genset does not fit speed sensor, please don't select corresponding items, otherwise, "start
d)
fail" or "loss speed signal" maybe caused.
If genset does not fit oil pressure sensor, please don't select corresponding items.

PARAMETERS SETTING
8.1 CONTROLLER PARAMETER SETTING
After controller is powered on, press
as follows:
1 Set Parameters
2 Information
3 Set Language
4 Event Log
5 Maintenance
6 Run Log
7 Maintenance Log
When password is inputted, "0318" can set all parameter items in Table 10. If the password is
changed, parameter setting can only be accessed by inputting the same password as the controller via
PC software configuration. If more parameters are needed to set, or password is forgot, for example,
voltage/current calibration, please contact the factory.
Attention:
a) Please change the controller parameters when generator is in standby mode only (e. g. Crank
disconnect conditions selection, auxiliary input, auxiliary output, various delay), otherwise, shutdown
and other abnormal conditions may occur.
b) Over voltage set limit must be higher than under voltage set limit, otherwise over voltage and under
voltage condition may occur simultaneously.
c) Over speed set value must be higher than under speed set value, otherwise over speed and under
speed condition may occur simultaneously.
d) Please set the generator frequency value as low as possible at cranking, in order to make the starter
be separated quickly as soon as possible.
e) Auxiliary input 1~6 could not be set as the same items; otherwise, they are abnormal functions.
However, the auxiliary output 1~5 can be set as the same items.
f) Programmable sensor 1 and sensor 2 both can be set as discrete input or analog input port. If
discrete input port is selected, corresponding discrete input settings are active; otherwise, if analog
input is selected, corresponding sensor parameters settings are active.
