6.6.5. Alarm adjustments
For each
Math Analog
,
Analog Input
and
Modbus channels,
two alarms are defined and can be configured to
several ouput forms (
see Figure 6.30
and
Figure 6.31
).
Name:
Maximum 12 characters long alarm name. Any character string can be entered in order to
name the alarm.
Type:
Any of
OFF
,
LOW
,
HIGH
,
SLOW RATE, FAST RATE
alarm types can be assigned to
alarms. Please check
Figure 6.30
and
Figure 6.31
for output forms.
Set/Deviation:
Defines set point for LOW and HIGH alarm types; deviation for SLOW RATE and FAST RATE
types.
Hysteresis:
Defines alarm hysteresis for LOW and HIGH alarms.
Latch Enable: Enabling latch causes alarm on state to persist until being acknowledged even if the alarm
condition is over.
Delay:
Alarms can be delayed for a certain amount of time in order to make sure the alarm
condition persists long enough. Any value between 0 and 9999 can be set in seconds.
Derivation
Time:
Define derivation time for SLOW and FAST RATE alarms. Please check
Figure 6.33
Filter:
Process values can be averaged in order to smooth unavoidable abrupt changes which may
cause false alarms. The filter value which can be set to any value from 1 to 10 determines
number of process values to be averaged for alarm calculations.
Off Message:
Maximum 100 characters long alarm off message.
On Message:
Maximum 100 characters long alarm on message.
