MicroLogic Active 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 Active control unit. These settings have no effect on protections.
System Type Setting
On 3-pole circuit breakers, the system type setting allows the activation of:
-
The ENCT (external neutral current transformer)
-
The ENVT (external neutral voltage tap, MicroLogic Active E/EP control units only)
The system type can be set on the MicroLogic Active display screen, from the tree navigation menu, at .
Rated Phase-to-Phase Voltage (MicroLogic Active E/EP)
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
Default = 400 V.
The rated voltage can be set on the MicroLogic Active E/EP display screen, from the tree navigation menu, at .
Rated Frequency (MicroLogic Active E/EP)
Available settings are:
-
50 Hz
-
60 Hz
The rated frequency can be set on the MicroLogic Active E/EP display screen, from the tree navigation menu, at .
After changing the rated frequency setting, the MicroLogic Active E/EP control unit must be restarted for the new setting to be taken into account.
Restart the MicroLogic Active E/EP control unit in one of the following ways:
-
Switch off the power supply to the MicroLogic Active E/EP control unit, and switch it back on.
-
Click the button on the page of EcoStruxure Power Commission software.
VT Ratio (MicroLogic Active E/EP)
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 on the MicroLogic Active E/EP display screen, from the tree navigation menu, at .
