─
Outlet pressure correlated setting: if flow and head are to be calculated via water pressure, one of auxiliary sensor 1-4
needs to be configured as outlet pressure sensor, and meanwhile, curve type needs to be the corresponding one. Then
set the outlet pressure correlated sensor and select the corresponding auxiliary sensor, and at this time, flow and head
can be calculated via water pressure.
─
If E-driven suction pump needs to judge whether it has stopped output by water pressure, outlet pressure correlation
setting is also needed.

Details of function description please see the following.
Act when over speed shutdown and emergence stop, and it can
close the air inflow to stop the engine sooner.
Act when warning and shutdown alarms occur, it can be

mute" is active or press any key on the panel, it can be stopped.
When new alarm or shutdown occurs, it will output again.
Act when engine is starting and disconnect when engine stops
completely.
It is controlled by fuel pump control threshold of level sensor.
It is controlled by heater control threshold of temperature
sensor.
It is controlled by cooler control threshold of temperature
sensor.
In standby status, when fuel pre-supply output is active, set fuel
pre-supply rest time and fuel pre-supply time are outputted
circularly. If set fuel pre-supply rest time is 0, fuel pre-supply is
