Buhler 2335, 2425, 2290, 2375, 2360 manual Yellow and Red Engine Warning Lights

SECTION 2 - OPERATION

Yellow and Red Engine Warning Lights

The EICS has two engine lamps located in the lower right hand corner of the warning light bar. The module on the side of the engine controls these lights.

The yellow engine warning light, 1, will illuminate when the module senses non--critical electrical faults. Non--critical faults are related to the engine electrical components that communicate with the module. These components receive data from or send data to the module, which is used to control the engine performance. When a fault is detected in one of the electrical component circuits, the module will notify the Operator by illuminating the yellow engine warning lamp. Examples of electrical faults that can cause the yellow lamp to illuminate are (but not limited to):

--Loss of ground speed signal into the module from the tractor EICS

--Low/High voltage at specific pin connectors of the module

--Open/Shorted circuits connected to the module

The red engine warning light, 1, will illuminate when the module senses critical faults. Critical faults are related to the module itself (internal hardware) or to the engine electrical components that communicate with the module. These components receive data from or send data to the module, which is used to control the engine performance. When a fault is detected in the module hardware or one of the electrical component circuits, the module will notify the Operator by illuminating the red engine warning lamp. Examples of electrical faults that can cause the red lamp to illuminate are (but not limited to):

--Failure of the internal microprocessor of the module

--High/Low voltage signal from the throttle POT inside the tractor cab

--Loss of engine speed signal into the module
