Earth-Leakage Test History
General Description
The earth-leakage test history registers describe the last 10 earth-leakage tests performed on a MicroLogic 7 trip unit. The earth-leakage test history format corresponds to a series of 10 records. Each record is composed of 5 registers describing one earth-leakage test.
The earth-leakage test history registers return 32768 (0x8000) when they are not used.
Earth-Leakage Test Number
A read request of 5 x n registers is necessary to read the last n earth-leakage test records, where 5 is the number of registers for each earth-leakage test record.
For example, a read request of 5 x 2 = 10 registers is necessary to read the last 2 earth-leakage test records of the earth-leakage test history:
-
The first 5 registers describe the first earth-leakage test record (most recent earth-leakage test).
-
The last 5 registers describe the second earth-leakage test record.
