DC20D MK2 GENSET CONTROLLER USER MANUAL
5
1. Summary
DC20D MK2 is one module used for Diesel/gasoline Generator, It's an
upgraded product of DC20D.It is with the functions of Auto Star/Stop, Protection and
Alarm indication. DC Power and Running situation is indicated on the front panel.
The status of the engine and generator can be checked conveniently because
these parameters of over speed, under speed, Over Frequency, Low Frequency,
Over Voltage, Under Voltage, Low Oil Pressure, High Temperature, Low Water Level,
Low Oil Level, Charge Failure, Over-time Stop, Emergency Stop Alarm System as
well as Low Battery Voltage can be indicated in time.
The output connector is connected with traditional relay which can burden more
output current. The parameters can also be set by the front face buttons so that it can
be used in different kinds of situations.
2. Main Features
Dual core 32bit high performance single chip microcomputer.
