Testing the status of the binary inputs/outputs
The 7SS60 differential protection includes a testing program that allows to check and
display the status of the binary inputs and outputs.
If the protection is operated from a personal computer using the DIGSI communication
software, the test addresses are identified by a four-digit number. This number will be
stated in brackets in the section below.
The block
$'',7,21)81&7,21
is accessed from the initial state of the device by
pressing three times the
key. Press
to move to the next operation level with the
block
7,0(6(77,1*
. Pressing the
key brings you now to the block
7(67$,'6
(
).
Move one level higher with the
key to access the block for testing the status of the
inputs and outputs
,267$7
(
).
Testing the
binary inputs
Press
once again to move to the address for testing the status of the binary inputs
%,67$7
(
).
After actuating the ENTER key E you are asked whether you want to interrogate the
status of the binary inputs. If you press the N key, the action is aborted, and you can
move to the next test item with
.
If you actuate Y/J, the status of the 3 binary inputs (BI) is shown as a matrix which has
the following meaning:
: BI 1 is activated (energized)
: BI 2 is activated (energized)
: BI 3 is activated (energized)
: The BI is not activated
Testing the signal
and command
relays
Press
to move to the address for testing the status of the signal and command
relays
5(67$7
(
).
After actuating the ENTER key E you are asked whether you want to interrogate the
status of the signal and command relays. If you press the N key, the action is aborted,
and you can move to the next test item with
.
If you actuate Y/J, the status of the 2 signal relays (S) and of the 2 command relays
(T) is shown as a matrix which has the following meaning:
: S 1 or T 1 has picked up
: S 2 or T 2 has picked up
: The relay has not picked up
%,67$7
In this example, the binary inputs 1 and 2 are activated,
whereas binary input 3 is not energized.
RE-STAT
S1-- T-2
In this example, the signal relay S 1 and the command relay
T 2 have picked up.
