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.
3.5 inch 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 Chinese/English 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 DC5xD MK3 series.
DC50D MK3: used for single machine automation. Start/Stop through remote
start signal.
DC52D MK3: Based on DC50D MK3, it adds Mains monitoring and AMF
(Mains/Generator automatic switching control), especially suitable for the automation
system composed by mains and genset.
DC50DR MK3: Based on DC50D MK3, it adds RS485 port.
DC52DR MK3: Based on DC52D MK3, it adds RS485 port.
Dual core 32bit high performance single chip microcomputer.
3.5 inch 240 * 128 high-resolution LCD screen, Available in 6 languages, user’s
language set if necessary.
Indicator and number display through UI surface.
Acrylic material is adapted to protect the screen.
Silicone panels;
USB Port: parameters can be set even without power through USD port to monitor
in real time.
With RS485 communication port, can achieve “Three Remote” functions via
MODBUS protocol.
Various kinds of parameters display.
Input/output function, status can be shown directly.
Real time clock inside: preset time operate and auto maintenance is available.
Genset working plan can be set as per week or month.
Maintenance countdown function, can set maintenance time or date.
The black box function can save the relevant parameters of the unit when the fault
alarm occurs in real time, and it is convenient to find the cause of the fault.
Totally 6relay’s output, among which 4 relay output can be self-configurable, each
relay can be set as max 20 functions, besides, there are 3 groups as non-contact
terminals.
With 5 switches input, up to 20 functions optional;
3 sensor simulation input connectors, the oil pressure sensor is compatible with
voltage signal input, and various display units can be configured.

Battery charging control function,which can protect the battery according to battery
voltage status.
Sensor can be self-defined by front face button or PC software.
Adapt to 3P4W,1P2W,2P3W(120V/240V,50/60HZ)
Various of crank conditions (RPM, Frequency, Oil Pressure) can be chosen.
Control Protection: Auto Start/Stop of genset, load transfer (ATS control) and
perfect failure display and protection.
Standard water-proof rubber gasket. The waterproof can reach IP54
Module design: All the connections are adapted with European connectors so that
installation, connection, repair and replacement can be more easily.
