15. AUTOCORRECT TECHNOLOGY: AUTOMATIC DETECTION
OF WIRING ERRORS AND SOFTWARE CORRECTION
The AutoCorrect technology enables the detection and software correction of wiring errors such as the connection of a
current sensor on the wrong phase.
If the DIRIS Digiware I or S module detects an incorrect voltage/current association between the voltage module and
the current module, a system alarm will be triggered on the DIRIS Digiware I/S module and on the DIRIS Digiware M
gateway or DIRIS Digiware D display.
15.1. Identifying the wiring error from the DIRIS Digiware D-50/D-70 display
• Go to PARAMETERS --> DEVICE ACTIONS
• Select a DIRIS Digiware S module or a DIRIS Digiware I module connected to iTR current sensors
• Choose a load
• Click on “AUTOCORRECT”
The AutoCorrect menu enables a live diagnostic of the system’s wiring. It indicates what is detected by the sensor thanks
to the embedded voltage detection feature and what should be corrected.
If the wiring is correct, the following table will be displayed for a three-phase load:

PRESS OK TO LAUNCH AUTOCORRECT
The table indicates that the load power P1 will be correctly calculated by associating current from the sensor
associated to input I01 with voltage V1 from the DIRIS Digiware U-xx module and if the CT way is DIRECT (p1 --> p2).
The resulting Power is positive (import/consumption).
Ex.1: DIRIS Digiware I module and iTR current sensors, with phase inversion of current sensors 1 and 3.
Let’s consider a phase inversion between current sensors 1 and 3, as showed in the following picture:
