ABB RED670 - Testing the Gas Medium Supervision for Pressure Alarm and Pressure Lockout Conditions; Testing the Gas Medium Supervision for Temperature Alarm and Temperature Lock out Conditions

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
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.
11.13.1.2 Testing the gas medium supervision for temperature alarm and
temperature lock out conditions
GUID-EC145626-90B0-45A2-AD58-CB8BF203FE16 v1
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.
