To set an alarm, select the following values:
■
Type of alarm.
■
Order of the harmonic (between 0 and 50), for |S-h|, A-h, U-h and V-h only.
■
Target of the alarm:
• 3L: 3 phases monitored individually
• N: monitoring of neutral
• 4L: 3 phases and neutral monitored individually
• Σ: surveillance of the value of the complete system
■
Direction of the alarm (>or <), for Hz, Urms, Vrms, Arms, |Udc|, |Vdc|, |Adc|, |Upk+|, |Vpk+|, |Apk+|, |Upk-|, |Vpk-| and
|Apk-|.
■
Triggering threshold (value and unit), for Urms, Vrms, Arms, |Udc|, |Vdc|, |Adc|, |Upk+|, |Vpk+|, |Apk+|, |Upk-|, |Vpk-|,
|Apk-|, |P|, |Pdc|, |Q
■
Minimum duration above or below the alarm threshold: in minutes, seconds, or also (for Vrms, Urms and Arms
[excluding the neutral]) in hundredths of a second.
■
Hysteresis: 1%, 2%, 5% or 10%.

Each overshoot of an alarm will be recorded in a campaign of alarms.
NOTE: Alarms appear in red if the configured quantity and/or target is incompatible with the selected configuration
(connection selected, sensors connected, ratios programmed, or calculation methods chosen).
Alarms on the level of harmonics of order 01 apply only to values expressed in %r.
If a search for alarms is in progress, the activated alarms cannot be modified and are identified by black spots. However, new alarms
(not yet programmed or not activated) can be activated.
