Network Settings
Presentation
The following settings are related to the characteristics of the local network. They are used by the measurement functions of the MicroLogic X control unit. These settings have no effect on protections.
Rated Phase-to-Phase Voltage
Available settings include: 208 V / 220 V / 230 V / 240 V / 380 V / 400 V / 415 V / 440 V / 480 V / 500 V / 525 V / 550 V / 575 V / 600 V / 660 V / 690 V / 1,000 V.
Default = 400 V.
The rated voltage can be set as follows:
-
On the MicroLogic X display screen, at
-
With EcoStruxure Power Commissionsoftware
Rated Frequency
Available settings are:
-
50 Hz
-
60 Hz
The rated frequency can be set as follows:
-
On the MicroLogic X display screen, at
-
With EcoStruxure Power Commissionsoftware
After changing the rated frequency setting, the MicroLogic X control unit must be restarted for the new setting to be taken into account.
Restart the MicroLogic X control unit in one of the following ways:
-
Switch off the power supply to the MicroLogic X control unit, and switch it back on.
-
Click the button on the page of EcoStruxure Power Commission software.
VT Ratio
The VT ratio is the ratio between the primary and the secondary rated voltages as measured by a voltage transformer (VT).
The value range for the primary voltage (VT in) is from 100–1,250 in increments of 1 (factory setting: 690).
The value range for the secondary voltage (VT out) is from 100–690 in increments of 1 (factory setting: 690).
The primary and secondary voltages can be set as follows:
-
On the MicroLogic X display screen, at
