Description
1726 702 16 bit 01.01.07 Global VOLTAGE_STATUS R Unsigned
The stored bytes contain information about the line voltage status and other operating states of the device. Each bit contains a specific
piece of information, as shown in the table.
bit Description
0 Line frequency out of limits *
1 Line voltage unbalance > Unb.1 *
2 Line voltage imbalance > Unb.2 *
3 Line voltage unbalance > Unb.3 * (30%_UNBALANCED_ERROR)
4 Rotation of phases 1-3-2 *
5 Three-phase line failure * (TRIPHASE_MISSING_LINE_ERROR)
6 Line frequency 60 Hz
7 Device not ready (DEVICE_NOT_READY)
8 DIP switch and EEPROM configuration error (MODE_ERROR)

The parameter sets the time constant value of the digital filter applied to the value read from the VT voltage transformer input. The filter
calculates the average of the values read in the specified time interval.
With 0.00 no filter is applied.
