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
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.
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 TempAlarmLimit, check that outputs TEMPALM and ALARM are
activated after a set time delay of tTempAlarm.
2. Temperature lockout input SETTLO can be used to set TEMPLO signal.
3. Also, increase further the temperature input above TempLOLimit, check that the
outputs TEMPLO and LOCKOUT appears after a set time delay of tTempLockOut.
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.

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.
