4.10. MODE ALARM MODE (FOR THE C.A 8333 ONLY)
The screen defines the alarms used by the Alarm Mode function (see §7).
You can define a alarm on each of the following parameters:
Hz, Urms, Vrms, Arms, Ucf, Vcf, Acf, Uthdf, Vthdf, Athdf, Uthdr, Vthdr, Athdr, |P|, |Q
1
| or N, D, S, |PF|, |cos Φ|, |tan Φ|, PST, FHL,
FK, Vunb (or Uunb for a three-phase source without neutral), Aunb, U-h, V-h, A-h and |S-h| (see the table of abbreviations in §2.9).
There are 10 programmable alarms.
To activate an alarm, move the yellow cursor to its number using the , keys, then validate with the
key. The active alarm is
identified by a red spot. An alarm that is not programmed (“?”) cannot be activated.
To program the alarm, move the yellow cursor using the ,, and keys, then validate with the
key. Change the value,
then validate again.

The type of alarm.
The order of the harmonic (between 0 and 50), for |S-h|, A-h, U-h and V-h only.
The 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.
The direction of the alarm (>or <) in the case of Hz, Urms, Vrms, Arms.
The triggering threshold of the alarm (value and unit for Urms, Vrms, Arms, |P|, |Q
1
| or N, D and S).
The 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.
The hysteresis: 1%, 2%, 5% or 10% (see §16.3).
