Monitoring

Gas medium supervision SSIMG

Prepare the IED for verification of settings as outlined in section
medium supervision for alarm and lock out conditions"
test"
in this chapter.
Check that the input logical signal BLOCK is logical zero and that on the local HMI,
the logical signals PRES_ALM, PRES_LO, TEMP_ALM and TEMP_LO are equal to
logical zero.

Testing the liquid medium supervision for alarm and lock out conditions

1.
Connect binary inputs to consider gas pressure and gas density to initiate the
alarms.
2.
Consider the analogue pressure input PRESSURE to initiate the alarms.
3.
Gas pressure lock out input can be used to set PRES_LO signal, check the signal
status in local HMI under Main menu/Test/Function status/Monitoring/Gas
medium supervision SSIMG/PRES_LO
4.
Reduce the pressure level input below PresAlmLimit, check for PRES_ALM
signal status in local HMI under Main menu/Test/Function status/
Monitoring/Gas medium supervision SSIMG/PRES_ALM
5.
Activate BLOCK binary input, the signals PRES_ALM, PRES_LO should
disappear.
6.
Reset the BLOCK binary input.
7.
Check for reset lock out input RESET_LO to reset PRES_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.

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.
