4.17 Configurable Binary Inputs
The IED has four binary inputs BI1 to BI4. Each binary input can be configured
individually and supports various features. Binary input BI1 is fixed for blocking
operation, whereas BI2 to BI4 are used for other than blocking operation. However
for binary input BI2 to BI4, user at a time can configure one operation per binary
input i.e., once any of the binary input BI2 to BI4 is configured for a particular
operation, it is not available for other operation.
1. Blocking: Binary input BI1 is dedicate for blocking protection and control
function. User depending on his need can configure this binary input to block
individual protection functions viz., I>, I>>, I>>>, Io> and Io>> as well as to
block breaker opening and closing command and trip circuit supervision e.g.
with open circuit breaker position.
The function configured for blocking will remain in block state until BI1 is active.
BI1 configured to block breaker opening and closing command
will block command received from local HMI or MODBUS or
binary input.
2. Circuit Breaker Status: Binary inputs BI2 to BI4 can be configured to indicate
the status of circuit breaker i.e. breaker open or breaker close or breaker in
maintenance. The available status information is sent to MODBUS
communication.
3. Circuit Breaker Command: Binary inputs BI2 to BI4 can be configured to
provide external (remote) breaker open or breaker close command.
For routing circuit breaker opening or closing command from
binary input, it is necessary that user also configures binary
output to receive respective command.
4. Reset: Binary input BI2 to BI4 can be configured for reset operation. When the
rising edge is detected, the IED resets all the protection and control functions
(all internal timers are reset). It also resets the Start, Trip, Trip Ip, Trip Io and
de-latches the binary output.
5. Trip Circuit Supervision: Binary input BI2 is used to receive the invalidity of
trip circuit. No other binary input can be used for this purpose.
6. To the Binary input BI2 to BI4 also user defined signals could be configured,
called Signal 1 to Signal 3. This Signals can be routed / connected in the
binary output configuration menu directly to binary output contacts and
additionally in the LED configuration menu to 5 LED’s.
All binary inputs BI1 to BI4 also support Inverted (I) operation.
