5.5.- OUTPUTS

The unit has two independent output relays:

5�5�1� TRIP RELAY, TRIP

Switched contact relay (terminals 13, 14 and 15 in Figure 1)

The unit can be programmed to modify the logical status of the contact (refer to section 5.6.3)

from the standard NC/NO status to the NO/NC positive safety status.

The positive safety status is shown on all screens that refer to the TRIP, with the + sign (Figure

14). The prealarm/fault screen will not be affected by this.

5�5�2� AUXILIARY RELAY, AUX

Simple contact relay (terminals 4 and 5, and Figure 1) non-interlocking. Its operation can be

programmed as a prealarm or fault relay (refer to section 5.6.2 )

Prealarm (ALAR), activated when the IΔ > 0.5•IΔn, in 200 milliseconds. The logical sta-

tus of the contact (refer to section 5.6.3) can be changed from the NO standard status to the

NC positive safety status.

The Fault relay (AUXF), is activated to notify fault events in the unit, such as:

undervoltages (the voltage is below the unit's operation voltage - the unit turns off below this

voltage) or faults in the external sensor.

In this case, the relay operates with the positive safety status.

Positive safety is shown with the + sign (only in the screens that refer to the AUX relay).
