Table of functions of the digital inputs
The table below lists all functions that can be assigned to the programmable digital inputs
INPx.
Each input can be set for the reverse function NO, as well as delayed energizing or de-
energizing, at independently set times. Some functions require another numeric parameter;
this is defined in the index (x) specified by parameter P10.n.02 Index (x).
For detailed information, see menu P10 - Digital inputs (Page 137).
Note
Use of an index
An index is used, if additional functions are to be used as a source for the input. For
example, an input can function as a source for a counter or for a user alarm.

Feedback Line 1
Auxiliary contact informing the ATC6300 whether
the breaker of Line 1 is open / closed. If this sig-
nal is not connected, the breaker for the
ATC6300 has the same status as the control
outputs.
Feedback Line 2
Auxiliary contact informing the ATC6300 whether
the breaker of Line 2 is open / closed. If this sig-
nal is not connected, the breaker for the
ATC6300 has the same status as the control
outputs.
Fault breaker Line 1 tripped (Trip 1)
If the contact is closed, it generates an alarm of
Line 1 circuit breaker protection intervention.
Fault breaker Line 2 tripped (Trip 1)
If the contact is closed, it generates an alarm of
Line 2 circuit breaker protection intervention.
Transfer to secondary line (remote switching)
If this contact is closed, the transfer to the sec-
ondary line is initiated even if the voltage of the
priority line is within the limit thresholds. It can be
used for switching the priorities between Line 1
and Line 2. The secondary line circuit breaker
remains activated for as long as this line is within
the limit thresholds. Can be used for the EJP
function.
Inhibit automatic return to priority line
If this contact is closed, it inhibits the automatic
return to the priority line if this supply is within the
limit thresholds again. It is used to prevent auto-
matic return from causing a further power cut at
an unforeseeable time.
Generator start (remote start without load)
If this contact is closed, it causes the generator to
start after the time set in P05.14 when in the AUT
mode. Can be used for the EJP function.
