Functions of Programmable Outputs
COD Function
OFF Output not used
OP.1 Line 1 circuit breaker open control (Open 1)
Contact which closes to command the opening of Line 1 circuit breaker.
It may remain energised or be released when the operation is completed, depending on P2.07 setting.
(not used when contactors or switches are used).
CL.1 Line 1 circuit breaker close control (Close 1)
Contact which closes to command the closing of Line 1 circuit breaker.
It may remain energised or be released when the operation is completed, depending on P2.07 setting.
OP.2 Line 2 circuit breaker open control (Open 2)
Like OP.1, referred to Line 2.
CL.2 Line 2 circuit breaker close control (Close 2)
Like CL.1, referred to Line 2.
OP.A Open control for both lines (Open All)
Used to set motorised switches to neutral position, with both lines open.
GC.1 Generator Control 1
Start / stop control for the generator connected to Line 1. When closed, it commands the shutdown of the generator set.
Used in Gen-Gen applications only.
GC.2 Generator Control 2
Start / stop control for the generator connected to Line 2. When closed, it commands the shutdown of the generating set.
Used in Util-Gen and Gen-Gen applications.
Rdy ATL Ready
It signals ATS in automatic mode and without alarms, ready to trip.
ALA Global Alarm
Energised output under standard conditions, de-energizes in the presence of any alarm.
L.SH Load Shed
Disconnection of non-priority loads which are not energised by the secondary line.
It is controlled also in MAN mode.
The contact is closed before secondary line close command and is opened before main line close command.
PrE Pre-Transfer
The output is energised before transferring the load from one line to the other, for the time set through P2.13.
PoS Post-Transfer
The output is energised after transferring the load from one line to the other, for the time set through P2.14.
L1.S Line 1 Status
The output is energised when there are all the conditions to connect load to Line 1.
L2.S Line 2 Status
The output is energised when there are all the conditions to connect load to Line 2.
