6
Line 2 in breaker tripped (Trip Q2) As above, referred to Q2.
7
Line 3 in breaker tripped (Trip Q3) As above, referred to Q3.
8
Line 1 breaker withdrawn
(Withdrawn Q1)
The input generates the breaker QQ1 withdrawn alarm when the
contact opens.
9
Line 2 breaker withdrawn
(Withdrawn Q2)
As above, referred to Q2.
10
Line 3 breaker withdrawn
(Withdrawn Q3)
As above, referred to Q3.
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 S.Q1 genset ready
When closed, indicates that the genset connected to the S.Q1 line is
available for use. Error A21 is generated if this signal is missing.
20
Line S.Q2 genset ready
When closed, indicates that the genset connected to the S.Q2 line is
available for use. Error A22 is generated if this signal is missing.
21
Line S.Q3 genset ready
When closed, indicates that the genset connected to the S.Q3 line is
available for use. Error A23 is generated if this signal is missing.
22
External line S.Q1 check
Line S.Q1 voltage from external equipment check signal. Activated
indicates voltage within limits.
23
External line S.Q2 check
As above, referred to line S.Q2.
24
External line S.Q3 check
As above, referred to line S.Q3.
25
Load enable on line S.Q1
Enables load connection on line S.Q1, in addition to internal controls.
26
Load enable on line S.Q2
As above, referred to line S.Q2.
27
Load enable on line S.Q3
As above, referred to line S.Q3.
28
Reset line S.Q1 delay
Resets line S.Q1 presence delay.
29
Reset line S.Q2 delay
As above, referred to line S.Q2.
30
Reset line S.Q3 delay
As above, referred to line S.Q3.
