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 “
5�6�3 FRE-
QUENCY AND STATUS OF THE OUTPUT RELAY CONTACTS”
) 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
“5�6�2 PROGRAMMING THE AUXILIARY RE-
LAY, AUX”
)
Prealarm (ALAR),
activated when the
IΔ
> 0.5•
IΔn
, in 200 milliseconds. The logical status
of the contact (
refer to
“
5�6�3 FREQUENCY AND STATUS OF THE OUTPUT RELAY CONTACTS”
)
can be changed from the NO standard status to the NC positive safety status.
The Fault relay
(
AUXF
), is a
ctivated 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).
