AUTORECLOSE FUNCTION OUTPUTS

The Autoreclose function has several logic outputs, which can be assigned to output relay contacts, monitor bits in
the COMMISSIONING TESTS column, or the PSL. The functions of these outputs are described below.
5.1

AR IN PROGRESS

This signal is present during the complete re-close cycle from the start of protection to the end of the reclaim time
or lockout.
5.2

AR IN PROGRESS 1 (DAR IN PROGRESS)

This operates together with the AR In Progress signal at the start of Autoreclose. If DAR Complete does not
operate, DAR in Progress remains operated until AR In Progress resets at the end of the cycle. If DAR Complete
goes high during the Autoreclose cycle, AR in Progress 1 resets.
5.3

SEQUENCE COUNTER STATUS DDB SIGNALS

During each Autoreclose cycle a sequence Counter increments by 1 after each fault trip and resets to zero at the
end of the cycle.
Seq Counter = 0 is set when the counter is at zero
●
● Seq Counter = 1 is set when the counter is at 1
Seq Counter = 2 is set when the counter is at 2
●
Seq Counter = 3 is set when the counter is at 3
●
● Seq Counter = 4 is set when the counter is at 4
5.4

SUCCESSFUL CLOSE

The Successful Close output indicates that an Autoreclose cycle has been successfully completed. A successful
Autoreclose signal is given after the protection has tripped the CB and it has reclosed successfully. The successful
Autoreclose output is reset at the next CB trip or from one of the reset lockout methods.
5.5

AR IN SERVICE

The AR In Service output indicates whether the Autoreclose is in or out of service. Autoreclose is In Service when
the device is in Auto mode and Out of Service when in the Non-Auto and Live Line modes.
5.6

BLOCK MAIN PROT (BLOCK MAIN PROTECTION)

The Block Main Prot signal blocks the DT-only stages (instantaneous stages) of the main current protection
elements. These are I>3, I>4, I>6, IN1>3, IN1>4, IN2>3, and IN2>4. You block the instantaneous stages for each
trip of the Autoreclose cycle using the Overcurrent and Earth Fault 1 and 2 settings, I> Blocking, IN1> Blocking,
IN2> Blocking and the Trip 1/2/3/4/5 Main settings.
5.7

BLOCK SEF PROT (BLOCK SEF PROTECTION)

The Block SEF Prot signal blocks the DT-only stages (instantaneous stages) of the SEF protection elements. These
are ISEF>3, and ISEF>4. You block the instantaneous SEF stages for each trip of the Autoreclose cycle using the
SEF PROTECTION setting ISEF> Blocking, and the Trip 1/2/3/4/5 SEF settings.
5.8

RECLOSE CHECKS

The Reclose Checks output indicates that the AR System Checks are in progress.
