- Self test 52 (breaker position self test, activated when inconsistencies are detected on
the auxiliary contacts)
Relays submenu example:
K1
00000001 hex Setting the self-test function on relay K1
K1 mode EN/NoLatch Setting relay K1 in normally energized and no latched mode
tTR1 200 ms Setting relay K1 minimum activation time
K2 00000200 hex Setting maximum overcurrent function trip on relay K2 (TRIP I>)
K2 mode DeEn-NoLatch Setting relay K2 in normally de-energized and no latched mode
tTR2 200 ms Setting relay K2 minimum activation time
K3 00000800 hex Setting ground fault function first threshold trip on relay K3 (TRIP IE>)
K3 mode DeEn-NoLatch Setting relay K3 in normally de-energized and no latched mode
tTR3 200 ms Setting relay K3 minimum activation time
K4 00000080 hex Setting ground fault function first threshold start on relay K4 (START IE>)
K4 mode DeEn-NoLatch Setting relay K4 in normally de-energized and no latched mode
tTR4 200 ms Setting relay K4 minimum activation time
Assignment of functions consists of the indication of those output relays for which each of the start
and
trip functions: I>, I>>, I>>, IE>, IE>>, IE>>, the overall Self test function, the block input pilot wire
self test function PW Break Blin1, the breaker failure output relay coil monitoring self test function
and the pilot wire short circuit self test function PW Shorted, is intended.
E
ach relay may be disabled by setting its assignment status to Off.
In order to alter the relay settings, click the mouse while the cursor is positioned over the corre-
sponding field.
Note: as with all modifications, the new settings only become operative after using the Store command found in the Store sub-menu.
When the Self-test function is assigned to a output relay, then the latter is automatically set with
positive logic (Energized) and automatic reset (No Latch) without any possibility of this being altered,
and is then excluded from the menu for the assignment of other functions. Hence, should any given
protective function be assigned to a output relay (for example K1), whenever the self test function is
assigned to K1, the above mentioned function becomes inactive (Off); if the given protective function
is assigned to two digital protection relays (for example K1, K2), then when the self test function is
assigned to K1, the aforementioned function remains assigned solely to relay K2.
R
elays intended for the Self-test function may not be assigned to other functions unless they are set
to Off and subsequently re-assigned.
