R.C02 - Alarm 1 threshold

R.C02 - Alarm 1 threshold
This parameter is available when alarm 1 is configured as
process or deviation output alarm (“A1.tP” [RF.01] = “Proc” or
“dEV”)
Upper display: Gr.3
Lower display: AL1
Range: - in engineering units within the span limits for process

alarm;

- from -1000 to 1000 digits for deviation alarm;

NOTE

NOTE: The span limits are related to the controlled variable set

by the "PVSL" [C.D02] parameter.

R.C03 -

Low threshold used when the

alarm 1 is a band alarm.

This parameter is available only when the alarm 1 is configured
as band alarm (“A1.tP” [RF.01] = “bAnd”)
Upper display: Gr.3
Lower display: bA1.L
Range: from 0 to -1000 digits.

R.C04 -

high threshold used when the alarm

1 is a band alarm.

1 is a band alarm.
This parameter is available only when the alarm 1 is configured
as band alarm (“A1.tP” [RF.01] = “bAnd”)
Upper display: Gr.3
Lower display: bA1.h
Range: from 0 to 1000 digits.
NOTE

NOTE

NOTE: The "bA1.L" and "bA1.h" values are algebraically added
to the operative set point in order to obtain the band limits.

R.C05 - Alarm 2 threshold

R.C05 - Alarm 2 threshold
This parameter is available when alarm 2 is configured as
process or deviation output alarm (“A2.tP” [RF.05] = “Proc” or
“dEV”).
Upper display: Gr.3
Lower display: AL2
Range: - in engineering units within the span limits for process

alarm;

- from -1000 to 1000 digits for deviation alarm;

NOTE

NOTE: The span limits are related to the controlled variable set

by the "PVSL" [C.D02] parameter.
