(*) Protection and Protection Counter alarms are only available with DIRIS Digiware S and when iTR current sensors are used with DIRIS Digiware I modules.
Active alarms and logs of timestamped finished alarms can be accessed from WEBVIEW and from the DIRIS Digiware
D-xx display.
13.1. System alarms
System alarms are activated upon detection of a commissioning error.
Voltage/current association
A “V/I association” alarm is activated upon detection of a wrong association between the current inputs of the DIRIS
Digiware I or S current module and the voltage inputs on the DIRIS Digiware U module:
-
If TE/TR/TF current sensors are used, this feature requires a certain load level: 0.6 < PF < 1 and I > 2% In
- If iTR current sensors or DIRIS Digiware S modules are used, the V/I association alarm also works off-load
Incorrect phase rotation (three-phase system only)
A “Phase rotation” alarm is activated upon detection of an incorrect direction of phase rotation (for example 3-2-1 instead
of 1-2-3).
CT disconnected
A “CT disconnected” alarm is activated upon disconnection of a current sensor from the DIRIS Digiware I module.
Incorrect CT primary
An “Incorrect CT primary” alarm is activated if the detected current sensor rating is different from the one configured in the
DIRIS Digiware I module.
Acknowledgement
System alarms can be acknowledged either:
- Automatically
- Via communication (from WEBVIEW, DIRIS Digiware D display or Modbus command)
- Via a digital input (for devices with digital inputs, such as DIRIS Digiware IO-10 and I-4x modules)
Output report
System alarms can be linked to a digital output for alarm reporting purposes.
Delay
A time delay can be configured at the start and the end of the alarm.
