Gas medium supervision SSIMG

Prepare the IED for verification of settings as outlined in Section
settings"
Values of logical signals for SSIMG protection are available on the local HMI under Main menu/
Tests/Function status/Monitoring/InsulationGas(63)/SSIMG(63):x, where x = 1, 2,....21.
The Signal Monitoring in PCM600 shows the same signals that are available on the local HMI.
Check that the input logical signal BLOCK is logical zero and that on the local HMI, the logical
signals PRESALM, PRESLO, TEMPALM, TEMPLO, ALARM and LOCKOUT are logical zero.

11.13.1.1 Testing the gas medium supervision for pressure alarm and pressure
lockout conditions
1. Connect binary inputs to consider gas pressure and gas density to initiate the alarms.
2. Consider the analogue pressure input SENPRES and set SENPRES to a value lower than
PresAlmLimit or activate binary input signal SENPRESALM, check that outputs PRESALM
and ALARM are activated after a set time delay of
3. Gas pressure lockout input SETPLO can be used to set PRESLO.
4. Also, reduce further the pressure level input below
input signal SENPRESLO, check that PRESLO signal appears after a set time delay of
tPressureLO .
5. Activate BLOCK binary input and check that the outputs PRESALM, PRESLO, ALARM and
LOCKOUT disappear.
6. Reset the BLOCK binary input.
7. Make sure that pressure lockout condition exists and then activate the reset lock out
input RESETLO and check that the outputs PRESLO and LOCKOUT reset.
11.13.1.2 Testing the gas medium supervision for temperature alarm and
temperature lock out conditions
1. Consider the analogue temperature input SENTEMP and set SENTEMP to a value higher
than
time delay of
2. Temperature lockout input SETTLO can be used to set TEMPLO signal.
3. Also, increase further the temperature input above
TEMPLO and LOCKOUT appears after a set time delay of
4. Activate BLOCK binary input and check that the outputs TEMPALM, TEMPLO, ALARM and
LOCKOUT disappear.
5. Reset the BLOCK binary input.
6. Make sure that temperature lockout condition exists and then activate the reset lock out
input RESETLO and check that the outputs TEMPLO and LOCKOUT reset.
