2.3. Switching Outputs
The DFA is equipped with 3 relay outputs (normally open contacts) which signal the relevant status of
the RCCB. It is possible to switch smaller loads directly via the relay contacts or, in the case of bigger
loads, with the aid of installation relays.
!
All relays have a common pole shared with terminal 8 and must be wired with the same potential.
The return signal for the toggle positions is produced via the terminals:
►
Feedback signal "connected" (terminal 5)
This contact is closed if the monitored RCCB is connected or if the DFA is not being supplied with
power.
►
Feedback signal "disconnected" (terminal 6)
This contact is closed if the monitored RCCB is disconnected.
►
Feedback signal "tripped" (terminal 7)
This contact is closed if the monitored RCCB has tripped.
►
Common pole (terminal 8)
This terminal is the shared reference point of terminals 5-7.
In addition the DFA has a relay output (changeover contact) which signals the blocked status of the
DFA. It is possible to switch smaller loads directly via this contact or, in the case of bigger loads, with
the aid of installation relays (see “Wiring”, p. 22).
►
Terminal 12: common pole
This terminal is the shared reference point of terminals 13 and 14.
►
Terminal 13: "blocked" (NC)
This contact is closed if an automatic reconnection attempt has failed and the remote actuator is
subsequently blocked or if the DFA is not being supplied with power.
Note: If the DFA is in the "blocked" status then standards stipulate that the cause must be identied.
The RCCB and system must be checked accordingly.
►
Terminal 14: "not blocked" (NO)
This contact is closed if all previous connection attempts have been able to be carried out without any
trouble.
Note: If the power supply of the DFA fails then the "connected" and "blocked" relay contacts will
close. If the switching status of the RCCB is undened then the "connected" and "disconnected" relay
contacts will switch alternately in a 1-s cycle.
