Resetting the Selective Catalytic Reduction (SCR) system
For DEF/AdBlue® storage tank fluid level faults, failures that can cause engine power loss:
• The DEF/AdBlue® tank level must be raised above
15 % total volume.
• The key switch must be cycled to the Off position or throttle returned to low idle position.
For DEF/AdBlue® quality and SCR system technical faults, failures that can cause engine power loss:
• To fully reset the system, the component/failure causing the fault must be repaired or replaced.
• Switching off the engine will reset the system and the engine will restart at full power.
• If the same failure is re-detected within
40 h of engine operation, the last active engine power loss level will be
activated.
• If the same failure is detected three consecutive times within
40 h of engine operation, maximum engine power loss
will remain active after engine restart until the system is repaired.
• Please contact your authorized CASE CONSTRUCTION dealer for service.
Emergency re-start
NOTE: Emergency re-starts are only enabled after the engine has been commanded to low idle.
If full power loss is experienced, it may be impossible for the machine to move under its own power. Emergency
re-starts are available to provide the capability to move the machine.
• Allows
30 s of operation without power loss.
• After
30 s , the engine is automatically reduced to low idle speed.
• There is no limit to the number of emergency re-starts
