Note (*) :
• When the set is in stepwise mode and, due to stepping-up,
a protection is activated, the set will really go into protection
(blinking LED). The set will not leave the stepwise-mode
however. If state X is the state where the set went to
protection, stepwise start-up will return to state X-1. At
state (X-1) diagnostic measurements can be performed.
Also, in the short time the set is in state X but not yet in
protection, you can also do some measurements.

5.5 Error Codes
5.5.1 Introduction
The error code buffer contains all detected errors since the last
time the buffer was erased. The buffer is written from left to
right, new errors are logged at the left side, and all other errors
shift one position to the right.
When an error has occurred, the error is added to the list of
errors, provided the list is not full or the error is a protection
error.
When an error occurs and the error buffer is full, then the new
error is not added, and the error buffer stays intact (history is
maintained), except when the error is a protection error.
To prevent that an occasional error stays in the list forever, the
error is removed from the list after 50+ operation hours.
When multiple errors occur (errors occurred within a short time
span), there is a high probability that there is some relation
between them.
5.5.2 How to read the Error Buffer
Use one of the following methods:
•
On screen via the SAM (only if you have a picture).
Examples:
– 0 0 0 0 0 : No errors detected
– 6 0 0 0 0 : Error code 6 is the last and only detected
error
– 9 6 0 0 0 : Error code 6 was first detected and error code
9 is the last detected error
• Via the blinking LED procedure (when you have no
picture). See next paragraph.
• Via ComPair.
