Description of the Micrologic 7 Trip Unit with Integrated Earth-Leakage Protection
Presentation
The Micrologic Vigi 7 electronic trip unit is available in two versions for earth-leakage detection:
o The Trip version trips when earth-leakage is detected.
o The Alarm version measures the earth-leakage current and indicates an earth-leakage fault on the display screen.
When the SDx indication contact is present, it signals an earth-leakage fault remotely.
Trip Unit Front Face
Use the display screen and keypad on the trip unit to set the trip unit options and check system measurements. Refer to the navigation principles for more information .
Front face of a Micrologic Vigi 7 trip unit (Trip version):
A Indication LEDs
B Adjustment dials for presetting protection functions, microswitch for locking protection setting, and test button for testing earth-leakage protection
C LCD display screen
D Navigation keypad
E Test port
F Dielectric switch
Indication LEDs
Indication LEDs show the trip unit operational state.
A Ready LED (green) blinks slowly when the standard protection functions of the electronic trip unit are operational.
B Overload pre-alarm LED (orange) lights when the load exceeds 90% of the Ir setting.
C Overload alarm LED (red) lights when the load exceeds 105% of the Ir setting.
Dials, Microswitch, and Test Button
The trip unit face has two adjustment dials for presetting protection functions, a microswitch for locking/unlocking the protection settings, and a test button for testing the earth-leakage protection.
LCD Display
An LCD display provides information necessary to use the trip unit. The list of protection functions varies according to the Micrologic trip unit type.
LCD Display Backlighting
When the Micrologic trip unit is powered by an external 24 Vdc power supply, the trip unit display has white backlighting that is:
o Low intensity continuously
o High intensity for 1 minute after pressing one of the keys on the keypad
The display backlighting is:
o Deactivated if the temperature exceeds 65 °C (149 °F).
o Reactivated once the temperature drops back below 60 °C (140 °F).
On trip units powered by the pocket battery, the display unit is not backlit.
Navigation Keypad
Use the 5-key keypad for navigation.
Micrologic trip units feature a test port specifically for maintenance actions.
Use the test port to:
o Connect a pocket battery for local testing of the Micrologic trip unit
o Connect the USB maintenance interface for testing, setting the Micrologic trip unit and for installation diagnostics
For more information, refer to Compact NSX - Circuit Breakers and Switch-Disconnectors 100–630 A - User Guide .
Dielectric Switch
The dielectric switch disconnects the trip unit power supply from the phases. It is used when performing a panel dielectric test.
For more information about how to use the dielectric switch, refer to Compact NSX - Circuit Breakers and Switch-Disconnectors 100–630 A - User Guide .
