Check that the input logical signal
BLOCK
is logical zero and that on the local HMI,
the logical signals
LVL_ALM
,
LVL_LO
,
TEMP_ALM
and
TEMP_LO
are equal to
logical zero.
10.12.2.1
Testing the liquid medium supervision for alarm and lock out conditions
1.
Connect the binary inputs to consider liquid level to initiate the alarms.
2.
Consider the analogue level input
LEVEL
to initiate the alarms.
3.
Liquid level lock out input can be used to set
LVL_LO
signal, check the signal
status in local HMI under
Main menu/Test/Function status/Monitoring/
Liquid medium supervision SSIML/LVL_LO
4.
Reduce the liquid level input below LevelAlmLimit, check for
LVL_ALM
signal
status in local HMI under
Main menu/Test/Function status/Monitoring/
Liquid medium supervision SSIML/LVL_ALM
5.
Activate
BLOCK
binary input, the signals
LVL_ALM
,
LVL_LO
should
disappear.
6.
Reset the
BLOCK
binary input.
7.
Check for reset lock out input
RESET_LO
to reset the
LVL_LO
lock out signal.
8.
Conduct these steps for temperature input as well to detect and reset
TEMP_ALM
and
TEMP_LO
signals.
9.
Continue to test another function or end the test by changing the
TestMode
setting to
Off
.
10.12.2.2
Completing the test
Continue to test another function or end the test by changing the
TestMode
setting to
Off
. Restore connections and settings to their original values, if they were changed for
testing purposes.

Breaker monitoring SSCBR
Prepare the IED for verification of settings outlined in section “Testing the IED
operation”.
The Signal Monitoring tool in PCM600 shows the service values that are available on
the Local HMI as well.
Values of the logical signals belong to the breaker monitoring are available on the
local HMI under:
