FAULT COUNTER
The counter is used to store validated transient type faults (elimination of the fault by resetting
sequences on the source unit).
It has a 4-digit LCD display.
The three counters (green, red, and polyphase) are displayed alternatively for 1 s (total duration).
The value “xxxx” displayed by a counter runs from 0000 to 9999.
To launch the display procedure, press the “counter display” button (PB3).
The display sequence is as follows:
1 s “POLY”
1 s “xxx”: polyphase counter
1 s “RED”
1 s “xxx”: red counter
1 s “GREEN”
1 s “xxx”: green counter
The three counters can be simultaneously reset by pressing the counter display button (PB3) for 3 s (you
should see “0” on the display).
