Illustration 6 g03094425
The Implement ECM will control the operation of the Implement Pilot Supply Solenoid according to the position of the Hydraulic Lockout Switch. Certain fault conditions will also cause the Implement ECM to use the solenoid valve to disable hydraulic operation. The ECM will disable the operation of the Implement System when the switch is in the LOCK position. When the switch is in the UNLOCK position, the normally closed switch contacts will ground the input circuit at ECM contact J1-34. When the ECM detects this grounded circuit, the ECM will energize the Implement Pilot Supply Solenoid. The energized solenoid will allow pilot oil to be supplied to the implement control valve.When the switch is in the LOCK position, the normally open switch contacts will ground the input circuit at ECM contact J1-33. When the ECM detects this grounded circuit, the ECM will de-energize the ON/OFF output for the Implement Pilot Supply Solenoid. Pilot oil will be blocked from the implement control valve. Implement Pilot Oil Filter Bypass Switch
Illustration 7 g03094426
The bypass switch is a pressure switch that shows whether the filter is plugged and the filter is being bypassed. This switch is normally open. When electrical power is applied to the switch, the switch closes. When the filter becomes plugged, the pressure of the oil opens the switch which allows the oil to bypass
