Gr. 3
Range: - in engineering units within the span limits for process
alarm;
- from -1000 to 1000 digits for deviation alarm;
- from 0.0% to 100.0 % for control output alarm.
NOTE: The span limits are configured by “ñ.In.L” [C.d05] and
“ñ.In.H” [C.d06].
- Low threshold used when the alarm 1 is a
band alarm - [r.C03]
This parameter is available only when the alarm 1 is configured
as band alarm (“A1.tP” [rF.01] = “bAnd”)
Range: from 0 to -1000 digits.
- high threshold used when the alarm 1 is a
band alarm - [r.C04]
This parameter is available only when the alarm 1 is configured
as band alarm (“A1.tP” [rF.01] = “bAnd”)
Range: from 0 to 1000 digits.
NOTE: The "bA1.L" and "bA1.h" values are algebraically added
to the operative set point in order to obtain the band limits.
- Alarm 2 threshold - [r.C05]
This parameter is available when alarm 2 is configured as
process, deviation, main control output or secondary control
output alarm (“A2.tP” [rF.05] = “Proc” or “dEV” or “ñAin” or
“SECn”)
Range: - in engineering units within the span limits for process
alarm;
- from -1000 to 1000 digits for deviation alarm;
- from 0.0% to 100.0 % for control output alarms.
NOTE: The span limits are configured by “ñ.In.L” [C.d05] and
“ñ.In.H” [C.d06].
- Low threshold used when the alarm 2 is a
band alarm - [r.C06]
This parameter is available only when the alarm 2 is configured
as band alarm (“A2.tP” [rF.05] = “bAnd”)
Range: from 0 to -1000 digits.
