Manual Extract: Friction Plate

When the engine oil pressure is low at idle speed, the low RPM pressure switch closes to ground. If the low RPM pressure switch closes, a ground signal goes through the closed switch to PIN 10.

A ground signal to PIN 10 causes the following:
1. The engine oil service monitor illuminates.
2. The alarm sounds ON and OFF.
3. The green Systems Normal light goes OFF.
4. If the tractor is equipped with an automatic shut-down system, 30 seconds after the alarm the tractor will shutdown.
When the engine oil pressure is low at 1800 engine RPM or greater, the high RPM pressure switch closes to ground. If the high RPM pressure switch closes, a ground signal goes through the closed switch to PIN 2.

A ground signal at PIN 2 will cause the same warnings shown above if the engine RPM is 1800 or greater. If the engine RPM is less than 1800 RPM, the high RPM pressure switch can be closed, but the ground signal to PIN 2 will not cause the warnings.
