R.C08 - Alarm 3 threshold

R.C08 - Alarm 3 threshold
This parameter is available when alarm 3 is configured as
process or deviation output alarm (“A3.tP” [RF.09] = “Proc” or
“dEV”).
Upper display: Gr.3
Lower display: AL3
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.C09 -

Low threshold used when the

alarm 3 is a band alarm.

This parameter is available only when the alarm 3 is configured
as band alarm (“A3.tP” [RF.09] = “bAnd”)
Upper display: Gr.3
Lower display: bA3.L
Range: from 0 to -1000 digits.

R.C06 -

Low threshold used when the alarm 2

is a band alarm.

is a band alarm.
This parameter is available only when the alarm 2 is configured
as band alarm (“A2.tP” [RF.05] = “bAnd”)
Upper display: Gr.3
Lower display: bA2.L
Range: from 0 to -1000 digits.

R.C07 -

high threshold used when the alarm

2 is a band

a l a r m .

This parameter is available only when the alarm 2 is configured
as band alarm (“A2.tP” [RF.05] = “bAnd”)
Upper display: Gr.3
Lower display: bA2.h
Range: from 0 to 1000 digits.
NOTE

NOTE

NOTE: The "bA2.L" and "bA2.h" values are algebraically added
to the operative set point in order to obtain the band limits.
