Besides the TRIP outputs, CLLKOUT should be set.
8.
Reset the lockout signal by activating the reset lockout (RSTLKOUT) signal.
9.
Activate the trip signal lockout function, set
TripLockout = On and repeat.
All trip outputs (TRL1, TRL2, TRL3) and functional outputs TRIP and TR3P must be active
and stay active after each fault, CLLKOUT should be set.
10. Reset the lockout.
All functional outputs should reset.
11.
Deactivate the trip signal lockout function, set
TripLockout = Off and the automatic
lockout function, set
AutoLock = Off.

Completing the test
SEMOD54375-203 v6
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.

9.8.1
Gas medium supervision SSIMG
GUID-0A83B4D5-51FF-43CB-8DC7-AFCEA2BC7B69 v3
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/
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.
Using service kit. prepare the IED for verification of settings as outlined in Section
in this chapter.
9.8.1.1
Testing the gas medium supervision for pressure alarm and pressure
lockout conditions
GUID-768DAAC8-F89D-4401-B86D-9B26FD7224F6 v3
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
tPressureAlarm.
3.
Gas pressure lockout input
SETPLO
can be used to set
PRESLO
.
4.
Also, 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.
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.
