FUNCTION CHARACTERISTICS
set to ON in the concerning menu).
[1]
The application of the IN1 binary input for the acquisition of the Block1 (logic block) coming from
external signal is shown in the following fi gure; in the example the block signal is ORed with Block2
(selective block) to block the generic (xxx) element.
TCS1 and TCS2
Trip Circuit Supervision.
Supervision with one or two binary input can be performed.
The exhaustive treatment of the TCS function is described in the concerning paragraph.
Trip ProtExt
The binary input detects a trip coming from an external protective relay: the information is available
for the breaker failure function (BF).
Reset counters
A change in status of a binary input effects a reset of all start/trip partial counters.

Reset CB Monitor
A change in status of a binary input effects a reset of all counters concerning the circuit breaker

CB Open counter
52a and 52b
The CB position can be acquired by means of binary inputs connected to the auxiliary contacts: the
information is used in the following functions:
CB position (open-closed)
CB diagnostic (N. of operations, trip time)
Breaker Failure (BF)
VT monitoring (74TV)
Note 1 The activation of one binary input produces indiscriminately a block of all protective elements programmed for being blocked from Block1
Note 2 The reset of the total counters is practicable by means ThySetter command with Session Level 1 (available with password)
