Monitoring system
Circuit for DEF level indication
It is used for monitoring the liquid level of DEF pot. This machine uses Perkins Electric Injection Engine
whose ECM sends the DEF liquid level signal to the meter by CAN bus. The meter microcontroller pro-
cesses information after reading liquid level data, and finally to actuate the DEF liquid level gauge.
Circuit for vehicle speed indication
For monitoring the machine speed condition. The output speed sensor, installed on the gearbox housing,
is used to detect the speed of gearbox output gear. The speed sensor consists of coil, permanent mag-
net and pole. The coil is wound outside the pole, and the pole is connected with the permanent magnet.
The magnetic field is formed around the permanent magnet, magnetic lines of force pass through air gap
and act on the teeth of gear, forming a closed magnetic circuit. When the gear is rotating, the magnetic
field acts on the tooth gap and tooth repeatedly, so the change in air gap is sometimes big and some-
times small; the flux changes with the air gap, and the changing flux induces sinusoidal signal in the coil,
which is in proportion to speed. Connect to ZF harness, followed by being processed in the electrical
control unit, the processed signal therefrom is sent to the instrument.
Service brake indication circuit
When sercive brake pressure is less than 9MPa, the pressure switch turns on and brake low pressure
indicator turns on.
