Section 10
Testing functionality by secondary injection
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
to verify settings"

10.12.1.2
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.
10.12.1.3
Testing the gas medium supervision for temperature alarm and
temperature lockout conditions
1.
Activate the binary input SENTEMPQ.
2.
Consider the analogue temperature input SENTEMP and set SENTEMP to a value higher than
TempAlarmLimit, check that outputs TEMPALM and ALARM are activated after a set time delay
of tTempAlarm.
3.
Temperature lockout input SETTLO can be used to set TEMPLO signal.
4.
Ensure that binary input SENTEMPQ is activated and increase further the temperature input
above TempLOLimit, check that the outputs TEMPLO and LOCKOUT appear after a set time
delay of tTempLockOut.

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.
