Alarms
Alarm priorities
Alarm status
Simulation The SIMULATE parameter allows transducer block output value to be simulated,
provided simulation has also been enabled at the device DIP switch. The simulation
must be enabled, a value and/or status entered and the block must be in AUTO
mode. During simulation the transducer output value is substituted by the simulated
value.
A simulation is also possible by switching the block to manual and entering a value for
OUT, see Chapter 7.2.
Parameter Description
ACK_OPTION
Sets the way in which alarms and warnings are to be acknowledged.
ALARM_HYS
Sets the hysteresis (in output engineering units) for all configured alarms.
A hysteresis of e.g. 2% on a HI_HI_LIMIT of 95% would cause the alarm
to activate when the level reaches 95% and to deactivate when the level
drops below 93%.
A hysteresis of e.g. 2% on a LO_LO_LIMIT of 5% would cause the alarm
to activate when the level drops below 5% and to deactivate when the
level rises to 7%.
HI_HI_PRI
The priority (1 – 15) of the HI_HI alarm
HI_HI_LIM
Sets the HI_HI alarm limit in output engineering units
HI_PRI
The priority (1 – 15) of the HI alarm
HI_LIM
Sets the HI warning limit in output engineering units
LO_PRI
The priority (1 – 15) of the LO alarm
LO_LIM
Sets the LO warning limit in output engineering units
LO_LO_PRI
The priority (1 – 15) of the LO_LO alarm
LO_LO_LIM
Sets the LO_LO alarm limit in output engineering units
Priority Description
0
Alarm is suppressed
1
Recognised by the system but not reported
2
Reported to the operator, but does not require his attention
3– 7
Advisroy alarms of increasing priority
8 – 15
Critical alarms of increasing priority
Parameter Description
HI_HI_ALM
The status of the HI_HI alarm
HI_ALM
The status of the HI alarm
LO_ALM
The status of the LO alarm
LO_LO_ALM
The status of the LO_LO alarm
Parameter Description
