Schematic of the switch circuit for the continuous flow and interlock overrideThe schematic is associated with the following machines: 216 (4NZ2500-UP) 226 (5FZ5200-UP) 228 (6BZ700-UP) 236 (4YZ4000-UP) 246 (5SZ4000-UP) 248 (6LZ1000-UP) 252 (FDG1-UP) 262 (CED1-UP) 267 (CMP1-UP) 277 (CNC1-UP) 287 (CNY1-UP)Test Step 1. CHECK FOR PROPER OPERATION
Enable the machine.
Push down on either the A1 switch or the A2 switch.
Push the continuous flow switch and then release the continuous flow switch.
Immediately release the auxiliary hydraulic switch.Note: If the auxiliary hydraulic switch is not released within one second of releasing the continuous flow switch, the continuous flow function will not be activated.Expected Result:The auxiliary hydraulics (A1 or A2) should be active.Results:
OK - The auxiliary hydraulics (A1 or A2) are active.Repair: There is no problem at this time. Stop.
NOT OK - The auxiliary hydraulics (A1 or A2) are not active. Proceed to Test Step 2.Test Step 2. CHECK THE STATUS OF THE SWITCH
Press the continuous flow switch.
Observe the status on the Caterpillar ET.
Release the switch.
Observe the status on the Caterpillar ET.Expected Result:The switch status should have changed from the "CLOSED" status to the "OPEN" status.Results:
OK - The status of the switch changed from the "CLOSED" status to the "OPEN" status.Repair: The ECM is very unlikely to have failed. Reconnect all connections and visually inspect
