Alarm parameters
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
Alarm priorities
Parameter 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
Alarm status
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
Simulation
The SIMULATE parameter allows the Sensor 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 Sensor output
value is substituted by the simulated value.
A simulation is also possible by switching MODE_BLK to "MAN" and entering a value for OUT.
Parameter Description
SIMULATE Enables, sets and displays a simulated value, options:
– enable/disable
– simulated value
– output value
