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