10.10 Monitoring
10.10.1 Gas medium supervision SSIMG
Prepare the IED for verification of settings as outlined in Section
in this chapter.
Values of logical signals for SSIMG protection are available on the local HMI under Main menu /
Test /Function status /Monitoring /InsulationGas /SSIMG: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.
Using service kit. prepare the IED for verification of settings as outlined in Section

10.10.1.2 Testing the gas medium supervision for pressure alarm and pressure
lockout conditions
1. Connect the binary inputs to consider gas pressure and gas density to initiate the alarms.
2. Activate the binary input SENPRESQ.
3. 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 tPressureAlarm .
4. Gas pressure lockout input SETPLO can be used to set PRESLO.
5. Ensure that binary input SENPRESQ is activated and reduce further the pressure level input
below PresLOLimit or activate the binary input signal SENPRESLO, check that PRESLO signal
appears after a set time delay of tPressureLO .
6. Activate BLOCK binary input and check that the outputs PRESALM, PRESLO, ALARM and
LOCKOUT disappears.
7. Reset the BLOCK binary input.
8. Ensure that pressure lockout condition exists and then activate the reset lockout input
RESETLO and check that the outputs PRESLO and LOCKOUT reset.

2.2.4 Binary quality inputs SENPRESQ and SENTEMPQ have been added for pressure and
temperature sensor signals in order to control alarm and lockout signals. Whenever there
is no sensor, the quality of the binary input will be low. If sensor quality is low, then
lockout and alarm signals will get reset.
