Fault frequency counter

This indicates how often a fault has recurred after its first occurrence. If the value is "1", the fault has occurred only once. Thus, it can now be "present" or "not present". The number in the fault frequency counter is increased by 1 whenever the fault status changes from "not present" to "present". A large value in the fault frequency counter thus might indicate a loose contact. It is important to remember that the ambient conditions stored in the "extended fault memory" relate only to the first and last occurrence of the fault.
