Warning
1.The installation of this equipment must be carried out by professionals.
2.When installing and operating the controller, please read the entire instruction
manual first.
3.Any maintenance and commissioning of the equipment must be familiar with all the
equipment.
4.t, safety standards and precautions in advance, otherwise it may cause personal
injury or damage to related equipment.
5.The engine must have an overspeed protection device independent of the
controller system to avoid casualties or other damage caused by engine out of
control.
6.After the installation of the controller is completed, please verify that all protection
functions are valid.
Be Care
1.Please keep the good connection of the power supply of the controller. Do not
share the connection lines of the positive and negative electrodes of the battery
with the floating charger.
2.During the operation of the engine, do not disconnect the battery, otherwise it may
cause damage to the controller.

1.Summary
This series controller is specialized for Diesel / Gasoline / Gas Genset Start,
Stop, Parameters monitoring, faults-checking as well as data setting.
4.3inch colorful LCD screen display with brand new UI design is adapted in this
controller that the relative failures can be displayed directly. All the parameters can
be displayed by simulated indicators and words. Besides, LCD screen can display
various faults in the same time that the genset will be stopped once it can’t work
smoothly.
There are Simplified Chinese, Traditional Chinese, English, Spanish, Russian
interface options, more language can be set according to user’s request. All the
parameters can be configured through the front face buttons or use programmable
interface by RS485 or USB to adjust via PC. It can be widely applied for all kinds of
auto control system of gensets.
2.Main Features
There are four Models under DC8xD MK3 series.
DC80D MK3: used for single machine automation. Start/Stop through remote
start signal.

6.Installation instruction
The controller is fixed by four special fixing members and screws, and the screws
of the metal fasteners cannot be too tight.
Panel Cutout: W220mm*H160mm.
220
160
Note: If the controller is installed directly in the genset shell or other fluctuated
equipment, the rubber pad must be installed.
Battery Voltage Input
DC8xD MK3 controller is suitable for 8-36V DC 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 than 2.5mm2.
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.
Output and relay expansion
Note: All outputs of the controller are relay contacts. The maximum current
capacity is described in the "Parameters" in this manual. Please use it in the relay
current capacity. If an extended relay is needed, add a continuous current diode
(when the extended relay coil is DC) or a resistance-capacitance loop (when the
extended relay coil is AC) to both ends of the coil to prevent interference with the
controller or other equipment.
AC current input
Current transformer with rated secondary current 5A 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

DC8xD MK3 GENSET CONTROLLER USER MANUAL
16
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.
