1. Summarize

Minco 820B genset controller adopts high performance microprocessor and industry components. It
has measuring, controlling, protection, four remote control, flexible software setting functions and high
anti-jamming ability. Can display all the measuring parameters, control parameters and genset running
state. Actually meets different types of generator auto control requirements . When the mains supply is
failure, the control system will automaticly give a start signal to start the genset and resume the power
supply in short time; After the mains supply is normal, the control system will unload and shut down
automaticly. Adding the monitoring function of mains supply electric quantity, applies to mains supply
and genset supply automatic transfer power supply system.

2. Characteristic

1. Double processing chip, real virtual value measuring, action smartly;

2. Mains and genset double power manager, Automatic Transfer Switch system;

3. Wide-screen LCD display with back-light;

4. Chinese and English double language menu, mutual operation, can be set and operated individually;

5. Auto start, Auto protection, ATS control;

6. Perfect auto protection, warning details and working statement character display directly, fault record

more than 50 items;

7. Double coolant temp., double oil pressure, fuel level and oil temp. etc connected parameters and so

on;

8. All relay contact capability is above 10A/250VAC/30VDC;

9. Electronic speed adjustment and mechanical speed adjustment control compatible, timing start or

stop and etc. custom setting; -

10. RS232 communication, attached “four remote control” monitor software;

3. Fixup dimension drawing

4. Function define and operate instruction

Attention: If “display change mode” set in “auto” switch state, the LCD display screen will switch to
next page after each 10 seconds; if “background light control” set in “auto” state, the LCD screen
background light will be auto turn off after three minutes without any operate. Once the fault appear or
press any key the background light turns on. If “Background light” control setting as “constant light”,
the LCD background light will keep lighting.

(3). Operation keys

Content Function

Press the key, when the above green LED keep bright, the controller is in “start” state,

start the genset in manual and keep running.

Press the key, when the above yellow LED keep bright, the controller is work in “auto”

state, once the “Remote start” switch input turn off and mains get right, the genset will
be stopped after delay. When “Remote start” switch input turn on the genset delay start
otherwise it’s delay cool down; If the genset reset by “remote reset”, once the “remote
reset” switch input turn off, the controller is in auto state.

Press the key, when the above red LED keep bright, the controller is work in

“stop/reset” state, it will unload, decelerate and idle stop, through idle stop cut off the
fuel. During decelerate and idle the “reset” indicator keep flash, keep light after stop.

Press the key, when the above red LED keep bright, the controller works in “testing”

state. Start the generator in manual, when the generator runs in normal, whatever the
mains supply is normal or not.The controller will automaticly close, onload and keep
running onloading.

(4). State indicator light

Content Function

Indicate the genset failure, protected stop, fault content display in the LCD sreen.

Indicate the genset warning information, alarm detail see screen.

Indicate “remote start” port state, use in monitor the main state generally.
