Manual Speed adjustment
Pin No.: J1-35(RAISE_SPEED), J1-47(LOWER_SPEED).
Functional description:
The manual speed control function consists of two switches, one is the speed-up
switch and the other is the speed-down switch, which can be used in manual
parallel or manual grid connection.
When the speed-up switch is closed, the engine will increase the speed at the
default speed of 5 rpm/s based on the original rated working speed. When the
speed-up switch is turned off, the engine will keep the value of the speed rising
until it is disconnected.
When the speed-down switch is closed, the engine will reduce the speed at the
default speed of 5 rpm/s based on the existing speed; when the two-pin connection
is disconnected, the engine will remain at the same speed as before the
disconnection.
The wire cross-sectional area is 0.75mm

.
This switch is manually parallel or connected to the grid. If there is no parallel or grid
connection, no connection is required.
The customer needs to prepare the manual switch by himself.

Speed Bias
Pin No.: J1-57(+), J1-45(-), J1-69(shield).
Functional description:
The automatic speed control function is generally used in control systems that require
automatic parallel or grid connection. Currently, the Weichai gas system supports two
forms of signal input.
A hard-wire signal input receives the GOV speed-regulating voltage signal of the
parallel or grid-connected controller through the SPEED_BIAS signal line at the end of
the whole vehicle harness, thereby realizing the speed regulation, and the receiving
