10.2 Description of error reactions
Error reaction Description of error reaction 1 Warning.
Error code is displayed.
Signal light in BOP (option) lights in 5 second intervals.
2 Function affected, the emergency function overrides the faulty function. Error code is displayed.
Signal light in BOP (option) lights in 5 second intervals.
3 Partial function faulty, overriding of the partial function by the emergency function is not possible .
After the occurrence of the fault the machine is stopped, after returning the travel lever to neutral the machine can move again.
The machine can still be driven to a limited extent, but must be repaired by the service department as soon as possible. Error code is displayed.
Signal light in BOP (option) lights in 5 second intervals.
4 Partial function faulty, overriding of the partial function by the emergency function is not possible . The machine is no longer able to drive, e.g. because parts of the travel system are defective " the diesel engine is shut down.
Error code is displayed.
Signal light in BOP (option) lights in 1 second intervals.
5 Fatal fault. The function of the control can no longer be guaranteed. Control is switched off.
Error code is displayed.
Signal light in BOP (option) lights permanently.
