7 Error Handling
Programmer PG 02 35
7.2 Error Memories
When the control is powered down it will lose any existing information on actual errors. In
order to be able to check upon which errors have occurred, a permanent error memory has
been incorporated in the control. Any errors that have occurred at least once will be stored
there, the order and the time of their occurrence, however, will be ignored.
The values stored in the error memory are treated by the control merely as monitor values
and are not any further taken account of. In other words, it is only the errors occurring
during operation that the control will respond to.
The permanent error memory can be inspected by means of the parameters that have been
assigned numbers from 3100 upward so that the numbers of permanently stored errors will
differ by 100 from those of the respective actual errors.
The permanent error memory can be cleared by means of the PC or the Hand Programmer
only. After clearance, the control will revert to accumulating any occurring errors in the
empty error memory.
When the parameter 5100 NoStoreSerrOn is set to “1” and the error memory
is then cleared, no errors will be stored in the error memory before the next
↑
3.8 Reset of Control Unit. This feature is to provide the possibility of shipping
a control with customer specific data in an error-free state without having to
stimulate the inputs with the correct values. The parameter 5100 itself cannot
be stored.
7.3 Emergency Shutdown Errors
The following list offers a summary of all errors that will cause an emergency shutdown
during operation or inhibit engine start. When at least one so-called fatal error has occurred
3800 EmergencyAlarm is activated and the signal “Governor ready” is cancelled.
If a fatal error has occurred automatic actuator calibration cannot be
performed.
