Programmable input functions table
The following table shows all the functions which can be associated to the programmable digital inputs INPn.
Each input may be set so as to have inverted function (NO - NC) because the energising or de-energising may be reset with independent times.
Other functions require a further numeric parameter defined by index (x) specified by parameter
P12.n.02
.

input.
1
Configurable Freely
configurable by the user.
2
Line 1 breaker closed (Feedback BRK1)
Auxiliary contact which informs the ATL of the open/closed state of breaker BRK1. If
this signal is not connected, ATL considers the state of the breaker corresponding to
the control output state.
3
Line 2 breaker closed (Feedback BRK2)
As above, referred to BRK2.
4
Line 3 breaker closed (Feedback BRK3)
As above, referred to BRK3.
5
Line 1 in breaker tripped (Trip BRK1)
The input generates breaker BRK1 protection tripping when the contact closes.
6
Line 2 in breaker tripped (Trip BRK2)
As above, referred to BRK2.
7
Line 3 in breaker tripped (Trip BRK3)
As above, referred to BRK3.
8
Line 1 breaker withdrawn (Withdrawn BRK1)
The input generates the breaker BRK1 withdrawn alarm when the contact opens.
9
Line 2 breaker withdrawn (Withdrawn BRK2)
As above, referred to BRK2.
10
Line 3 breaker withdrawn (Withdrawn BRK3)
As above, referred to BRK3.
11
Transfer to secondary load (remote start on-load)
When closed, causes the priority line detachment and transfer to the first available line.
Also if the main line voltage returns within limits. The secondary line breaker remains
active until it is comprised in the limits. May also be used for the EJP function.
12
Automatic return to priority line inhibition
In AUT mode, when closed, prevents automatic return to the priority line after it returns
into the limits. (Prevents opening of the line in use in the following conditions: input
closed and so line in limits).
This prevents the second energy interruption caused by retransfer occuring
automatically in an unpredictable moment.
13
Automatic return to priority line in open transition inhibition
In AUT mode, when closed, prevents automatic return to the priority line in open
transition after it returns into the limits. (Prevents opening of the line in use in the
following conditions: input closed and so line in limits).
This prevents the second energy interruption caused by retransfer occurring
automatically in an unpredictable moment in open transition.
14
Priority genset start (Off load)
In AUT mode, when closed, causes the starting of the priority genset after the time set
with Pxx.xx. May also be used for the EJP function.
15
Start genset 1
In AUT mode, when closed, overrides starting of genset 1.
16
Start genset 2
As above, referred to genset 2.
17
Start genset 3
As above, referred to genset 3.
18
Emergency
NC contact which, if open, opens all the breakers and generates alarm
A14 Emergency
(block property of A14 are priority) .
19
Line SRC1 genset ready
When closed, indicates that the genset connected to the SRC1 line is available for use.
Error A21 is generated if this signal is missing.
20
Line SRC2 genset ready
When closed, indicates that the genset connected to the SRC2 line is available for use.
Error A22 is generated if this signal is missing.
21
Line SRC3 genset ready
When closed, indicates that the genset connected to the SRC3 line is available for use.
Error A23 is generated if this signal is missing.
22
External line SRC1 check
Line SRC1 voltage from external equipment check signal. Activated indicates voltage
within limits.
23
External line SRC2 check
As above, referred to line SRC2.
24
External line SRC3 check
As above, referred to line SRC3.
25
Load enable on line SRC1
Enables load connection on line SRC1, in addition to internal controls.
26
Load enable on line SRC2
As above, referred to line SRC2.
27
Load enable on line SRC3
As above, referred to line SRC3.
28
Reset line SRC1 delay
Resets line SRC1 presence delay.
29
Reset line SRC2 delay
As above, referred to line SRC2.
30
Reset line SRC3 delay
As above, referred to line SRC3.
31
Keypad lock
If closed, locks all front keyboard functions except for measurement display.
32
Parameter setting lock
If closed, the setup menu access is locked.
33
Remote control lock
Locks control and writing operations via serial port. Data reading is always
possible.
34
Siren OFF
Deactivates the siren.
35
Automatic test
Starts a periodical test managed by an external timer.
36
Local battery charger alarm
With the input active, alarm signal
A10 External battery charger failure
supplied by a
line. The alarm is generated only when mains voltage is present.
37
Battery charger 1 alarm
With the input active, indicates alarm
A11 genset 1 battery charger failure
supplied
by line SRC1. The alarm is generated only when SRC1 voltage is present.
38
Battery charger 2 alarm
As above, referred to line SRC2 (alarm A12).
39
Battery charger 3 alarm
As above, referred to line SRC3 (alarm A13).
40
Alarm inhibition
This allows, when active, to enable the alarms with alarms active inhibition properties
41
Reset alarms
Reset retraining alarms the causing condition of which has ceased.
42
Control menu C(xx)
Executes the command menu control defined by the index parameter (xx).
43
