HAZArD!
Supply the protection unit always and continually with voltage in the range
of 110...220Vac/dc. Supply terminals: r+(“+”) and r2-(“-”).
LCD DISPLAY
Indicates the instantaneous currents by phase, set parameters, frequency,
faults occurred and information of self-diagnosis of the protection unit.
LED RUN The LED flashes intermittently in normal operation.
LED PICK UP Signals beginning of trip timing.
LED LTD Signals tripping through overload (L function).
LED STD Signals tripping through timed short circuit (S function).
LED INST Signals tripping through instantaneous short circuit (I function).
LED PAL Signals pre-alarm.
RESET key To reset the alarm contacts and the LEDs of signaling of faults.
MODE key To return to the previous menu.
ENT key To access the menus.
�and� keys To advance / go back.
Start Screen
When first turned on, the protection unit presents the screen below on the display for
approximately 2 seconds:
ACB OCR-II
Vx.x
After this period, the standard screen is presented, where the values of the instantaneous
currents by phase are read:
R: * * * * S: * * * *
T: * * * * N: * * * *
AttentIon!
In the case of instantaneous current being less than 5% of the maximum
nominal current (In max.) of the circuit breaker, “****” will be shown on the
display.
Indication/Signaling of the occurrence of Faults
In case of tripping through overload or a short circuit, the protection unit indicates the fault
through the LCD display, and signals it through the LEDs in the front and alarm contacts.
