4.1.8 ALARM MODE CONFIGURATION

The Alarm mode menu defines the alarms used by the Alarm mode function (see § 5.4 for a complete list of alarms).
To activate an alarm, highlight it using the up and down arrow buttons, then confirm the selection by pressing
active alarm is identified by a red spot. An alarm that is not programmed (identified by a question mark "?") cannot be
activated. To program the alarm, select the parameter, then enter a new value. Confirm the change by pressing
The Alarm mode menu defines:
● 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 <) in the case of Hz, Urms, Vrms, Arms, |Udc|, |Vdc|, |Adc|, |Upk+|, |Vpk+|, |Apk+|,
|Upk-|, |Vpk-| and |Apk-|.
● Triggering threshold of the alarm (value and unit for Urms, Vrms, Arms, |Udc|, |Vdc|, |Adc|, |Upk+|, |Vpk+|, |Apk+|,
|Upk-|, |Vpk-|, |Apk-|, |P|, |Pdc|, |Q1| or N, D and S).
● Triggering delay, or minimum duration above or below the alarm threshold: in minutes or seconds or, in the case
of Vrms, Urms and Arms (excluding the neutral), in hundredths of a second.
● Hysteresis: 1%, 2%, 5% or 10% (see § A.1).
To go from one page to the other, press the
campaign of alarms.
NOTE: A red alarm indicates the programmed quantity and/or target is incompatible with the configuration chosen
(connection selected, sensors connected, ratios programmed, calculation methods chosen).
The alarms on the level of harmonics of order 01 concern only the values expressed in % r.
If a search for alarms is in progress, the activated alarms cannot be modified and are identified by black dots. How-
ever, new alarms (not yet programmed or not activated) can be activated.
