4.9.4.2
High threshold configuration
An audible signal is emitted at values
exceeding the threshold (detection of
an earthing impedance that is too
high).
Fig. 12
If the impedance crosses the selected threshold, a low-pitched audible signal is
emitted.
4.9.4.3
Priority of the alarms
If several alarms are triggered simultaneously, a priority rule determines the
display and the corresponding sound:
■
The voltage alarm has priority because it concerns the user's safety.
■
The current alarm is second in priority.
■
The impedance alarm is displayed when no other alarm is triggered.
