DIRIS DIGIWARE - 546420C - SOCOMEC
13. alarms
The threshold alarms on measurements are only available with DIRIS Digiware U-30, S-135, S-Datacenter
and IO-20.
The alarms on digital inputs with change of output status are available on DIRIS Digiware IO-10.
13.1. alarms upon events
Alarms can be generated when a threshold is exceeded for electrical measurements, consumption, variations in
level or change in input status. Also, combinations can be made on the alarms created.
Up to 23 detected alarms are saved and timestamped; an alarm can have 3 distinct statuses: Alarm active, Alarm
finished, Alarm finished and acknowledged. Alarms can be acknowledged either automatically or by user action, as
required.
Up to 9 alarms on electrical measurements can be configured per equipment and 4 for the status change of a
digital input. The digital inputs are available on DIRIS Digiware IO-10.
The alarms are configured via the Easy Config software.
13 .1 .1 . Electrical parameters
The alarms available are based on electrical parameters measured in the devices.
• Alarm upon variation in the instantaneous or average value of an electrical value: Current, voltage, frequency,
power, power factor, Cos phi, harmonic distortion or an analogue quantity on the DIRIS Digiware IO-20 module.
• Selection of the hysteresis and high/low threshold.
• Setting a time delay at the start and end of the alarm.
• For the associated total harmonic distortion, voltage and current three-phase values, an alarm may be generated
if the condition is fulfilled on a combination of phases:
- On a single-phase: Phase1, Phase2, Phase3
- On all the phases simultaneously: Phase1 and Phase2 and Phase3
- On one phase of the three phases: Phase1 or Phase2 or Phase3
