Functions of programmable Inputs
COD Function
OFF Input not used
Fb.1 Line 1 circuit breaker closed (Feedback 1)
Auxiliary contact informing the ATL of the open/closed status of Line 1 circuit breaker.
If this signal is not programmed, ATL considers the status of the circuit breaker based on the status of control outputs.
Fb.2 Line 2 circuit breaker closed (Feedback 2)
Like Fb.1, referred to Line 2.
tr.1 Line 1 circuit breaker protection (Trip 1)
When the contact is closed, it generates an alarm of Line 1 circuit breaker protection trip.
tr.2 Line 2 circuit breaker protection (Trip 2)
Like tr.1, referred to Line 2.
dr.1 Line 1 circuit breaker withdrawn (Withdrawn 1)
When the contact is open, it generates an alarm of Line 1 circuit breaker withdrawn.
dr.2 Line 2 circuit breaker withdrawn (Withdrawn 2)
Like dr.1, referred to Line 2.
E.tr Transfer to secondary line
When closed, causes changeover to secondary line even if main line voltage is within limits.
The secondary line circuit breaker remains activated until this line remains within limits.
Can be used for EJP function.
It can also be used to select the line priority. With closed input, Line 2 becomes the priority one.
In.r Inhibit Return to main line
In AUT mode, when closed, it inhibits the return to main line after it is restored within the limit range.
It is used to prevent the second power cutout due to re-transfer from occurring automatically at an unforeseeable time.
S.GE Start Generator
In AUT mode, when closed, it causes the generator to start after the delay specified by P2.26.
It can be used for EJP function.
EME Emergency
NC contact which, if open, causes both circuit breakers to open and generates alarm A09.
Gr.1 Line 1 generator ready (Generator ready 1)
When closed, it signals that the generator connected to Line 1 is available for use.
If this signal is missing, alarm A08 is generated.
Gr.2 Line 2 generator ready (Generator ready 2)
Like Gr.1.
E.L1 Enable load on Line 1 (Enable Load 1)
It allows load connection on
Line 1, in addition to internal controls.
E.L2 Enable load on Line 2 (Enable Load 2)
Like E.L1, referred to Line 2.
E.C1 External control of Line 1 (External control 1)
Signal showing that Line 1 is within limits.
It replaces internal controls.
E.C2 External control of Line 2 (External control 2)
Like E.C1, referred to Line 2.
Loc Keypad lock
If closed, it locks all the functions from front keypad except measurement viewing.
L.PA Lock Parameters set-up
If closed, it locks the access to set-up menus.
L.rc Lock remote control
If closed, locks write access through serial interface ports.
S.by Stand-by
When activated, the opening of the changeover switches and the subsequent shutdown of the eventual gene rating sets.
