Installation instruction
The controller should be installed by four accessories and screw.
Panel Cutout：W78mm*H66mm.
78
66
Note: If the controller is installed directly in the genset shell or other fluctuated
equipment, the rubber pad must be installed.
Battery Voltage Input
DC30D controller is suitable for 98-18 VDC battery voltage. Battery negative must be
reliably connected to the enclosure of the engine. The controller power supply B+
and B- must be connected to battery positive and negative, and the wire size must
not be less then 1.5mm2.
NOTE:
In case of floating charger connect charger output to battery positive and negative
directly, then, connect battery positive and negative poles to controller positive and
negative power supply
AC current input
Current transformer with rated secondary current 62.5mA must be externally
connected to the controller current input.
WARNING:When generator is on-load, C. T. secondary must not be open
circuit, Otherwise, the high voltage generated will pose a danger to personal safety.
Withstanding voltage test
If withstanding voltage test is conducted after the controller has already been
installed onto the control panel, please unplug all controller terminal connections in
order to prevent high voltage from damaging it.

Control and operation instruction
Manual Start
In stop mode turn the starter key from OFF to ON position to power on the
controller, then change the starter key position to START to begin cranking; after the
engine fires, release the starter key(crank disconnect condition is gen
frequency>14.0Hz), then the controller can monitor and display the relevant
parameters of the generator set in real time.
Manual stop
Under any circumstances, if starter key is turned from ON to OFF position, it will
lead to shutdown.
Please note before manually start:
1) Please make sure if the connection is right and meet requests.
2) There is fuse in the DC power of controller and make sure if the battery + and - are
connected rightly.
3) Please make sure if all the parameters are right and the oil pressure indicators are
in normal light.
4) Please take appropriate measurement so that the genset shall be stopped under
emergency.
5) Manual start mode:
Press the "STOP" to ensure the stop gear before starting. Press "MANUAL"
manual gear indicator light on, at this time will detect the normal connection of
each sensor, if the sensor is open, then report the sensor open alarm, if normal, then
execute the start-up process of the unit. When the unit is running normally, press the
"STOP" and the controller will perform the parking process in the following
sequence:

8) Notices in Starting Process
Note 1: During the Cranking time, the controller automatically detects the speed
signal, frequency signal and oil pressure value (according to the parameter setting) to
reach the judgment condition of successful start, then the judgment is that the start is
successful and the motor relay is closed.
Note 2: Within the safety delay, only respond to emergency stop, immediate
stop, over speed, over frequency, other alarms are not responded to.
Note 3: No response to alarm and warning of underspeed, low frequency, under
voltage, over current during start idle time.
Note 4: No response to low frequency, under voltage, over current and over
power is required when entering the Warming-up time.
Note 5: After entering rated operation, the Gens load relay output.
