description

1

emergency shut down

When the controller detects the emergency stop alarm signal, the controller sends the shutdown alarm signal and displays the emergency stop on the LCD screen.

 
2

 High water / cylinder temperature alarm for shutdown

When the water / cylinder temperature value detected by the controller is greater than the set water / cylinder temperature stop value, the controller sends a shutdown alarm signal and displays on the LCD screen.

 
3

 
 Low oil pressure alarm for shutdown

When the oil pressure value detected by the controller is less than the set oil pressure alarm value, the controller sends out an alarm signal, and the low oil pressure and alarm stop word is displayed on the LCD screen.

 
4

 
 Overspeed alarm shutdown

When the controller detects that the speed of the generator set exceeds the set overspeed stop threshold, the controller sends a shutdown alarm signal, and the overspeed alarm stop appears on the LCD screen.

 
5

 
 Overtime alarm shutdown

When the controller detects that the speed of the generator set is less than the set shutdown threshold, the controller sends a shutdown alarm signal and the slow alarm shutdown appears on the LCD screen.

 
6

 Speed signal loss and alarm shutdown

When the controller detects that the speed of the generator set is equal to zero and the speed signal loss delay is set to non-0, the controller issues a shutdown alarm signal, and the speed signal loss alarm shutdown is displayed on the LCD screen.

 
7

 
 Power generation, overvoltage alarm and shutdown

When the controller detects that the voltage of the generator set is greater than the set overvoltage shutdown threshold, the controller sends a shutdown alarm signal, and the high voltage alarm of each phase is displayed on the LCD screen.

 
8

 
 Power generation undervoltage alarm shutdown

When the controller detects that the voltage of the generator set is less than the set undervoltage shutdown threshold, the controller sends a shutdown alarm signal, and the low alarm shutdown of each phase is displayed on the LCD screen.

 
9

 
 Power generation, overcurrent alarm and shutdown

When the controller detects that the current of the generator set is greater than the set overflow shutdown threshold, the controller sends out an alarm signal, and the power generation overload alarm shutdown appears on the LCD screen.

 
10

 
 Start failure and alarm shutdown

Within the set start times, if the generator set is not started successfully, the controller sends out a shutdown alarm signal, and the start failure alarm stop is displayed on the LCD screen.

 
11

 
 Overfrequency alarm shutdown

When the controller detects that the frequency of the generator set exceeds the set overspeed stop threshold, the controller sends a shutdown alarm signal, and the high frequency alarm shutdown is displayed on the LCD screen.

 
12

 
 Overtime alarm shutdown

When the controller detects that the frequency of the generator set is less than the set shutdown threshold, the controller sends a shutdown alarm signal and the low frequency alarm shutdown is displayed on the LCD screen.

13

 No power generation alarm or shutdown

When the controller detects that the frequency of the generator set is equal to zero, the controller sends a shutdown alarm signal, and the LCD screen displays no generation alarm shutdown.

14

 Low fuel level alarm shutdown

When the controller detects that the fuel low shutdown input is valid, the controller sends a shutdown alarm signal and the word "low fuel alarm shutdown (IN)" is displayed on the LCD screen.

 
15

 Low cooling liquid level alarm shutdown

When the controller detects that the coolant level shutdown input is valid, the controller sends a shutdown alarm signal and the low coolant level alarm shutdown (IN) is displayed on the LCD screen.

16

 The temperature sensor is in an open-stop state
machine

When the sensor is not properly connected to the corresponding port, the controller sends a shutdown alarm signal, and the temperature sensor fault shutdown is displayed on the LCD screen.

17

 Oil pressure sensor open circuit shutdown

When the sensor is not properly connected to the corresponding port, the controller sends a shutdown alarm signal, and the oil pressure sensor shutdown is displayed on the LCD screen.

 
 
18

 
 
 Maintenance time to downtime

The maintenance type is the operation time. When the operation time of the generator set is greater than the maintenance time set by the user, or the maintenance type is the date, the current date exceeds the set date, and the maintenance action is set to alarm shutdown, the controller issues the shutdown alarm signal, and the word maintenance time to alarm shutdown is displayed on the LCD screen. The maintenance parameter can be reset by using the maintenance password to set the maintenance alarm.

19

 Input port alarm shutdown

When the controller detects that the external shutdown alarm input is valid, the controller sends the shutdown alarm signal and the LCD screen displays the external input alarm shutdown (IN).

 
20

 
 Overpower shutdown alarm

When the controller detects that the power value (positive power) of the generator set is greater than the set threshold value, and the overpower action type selects the alarm shutdown, the LCD screen displays the words of active power overload shutdown.

 
21

 
 Overcurrent fault shutdown alarm

When the controller detects that the overcurrent fault shutdown input is valid, the controller sends a shutdown alarm signal, and the overcurrent fault alarm shutdown (IN) is displayed on the LCD screen.

22

 Overspeed shutdown input alarm

When the controller detects that the overspeed stop input is valid, the controller sends a shutdown alarm signal and the overspeed alarm stop (IN) is displayed on the LCD screen.

 
 
23

 
 Temperature sensor 2 fault shutdown

When the temperature sensor connected to the programmable sensor interface is open, and the parameter configuration of the programmable sensor open circuit action is set as alarm shutdown, the controller sends out an alarm signal, and the temperature sensor 2 fault shutdown is displayed on the LCD screen.

 
 
24

 
 Pressure sensor 2 fault shutdown

When the pressure sensor connected to the programmable sensor interface is open, and the open circuit action of the programmable sensor is configured as alarm shutdown, the controller sends out an alarm signal, and the pressure sensor 2 is displayed on the LCD screen.
