Trip History
General Description
The trip history registers describe the last 10 encountered trips. The trip history format corresponds to a series of 10 records saved in a FIFO (first in first out) stack. The last record erases the oldest. Each record is composed of 20 registers describing one trip.
Register 9098 returns the number of faults recorded in the trip history (FIFO).
Register 9099 returns the value of the pointer for the last fault recorded in the trip history.
Example:
If the register 9098 = 10 and the register 9099 = 5, then the last fault recorded is the trip record 5.
In this case, the last but one is the alarm record 4.
-
The contacts must be inspected each time the counter reaches a hundred mark.
-
The message is displayed if the characteristics of the circuit breaker have not been defined. In this case, see in the menu on the MicroLogic HMI, in registers 9846–9853.

Trip Record Number
A read request of 20x(n) registers is necessary to read the last n trip records, where 20 is the number of registers for each trip record.
For example, a read request of 20x3 = 60 registers is necessary to read the last 3 trip records of the trip history:
-
The first 20 registers describe the first trip record.
-
The next 20 registers describe the second trip record.
-
The last 20 registers describe the third trip record.
