7.3 Alarm Mode Configuration (PRoG > ALM.1, ALM.2)
Select Alarm Configuration 1 (ALM.1) or Alarm Configuration 2 (ALM.2) in order to set up,
change, enable, or disable Alarms. Either or both Alarms can be assigned to trigger display
color changes, annunciators, and / or outputs. Either or both Alarm configurations can be
assigned to multiple outputs. The ALM.1 and ALM.2 configuration menus have all of the
same settings and function in the same manner.
Navigate to the Alarm setting to change. Settings include the following:

tyPE

Ab.dV – Alarm references values (ALR.H and ALR.L) or deviation from SP1 or SP2

ALR.H – Alarm high parameter, used for Alarm trigger calculations

ALR.L

A.CLR – Alarm color indication

HI.HI

LtCH

CtCL

A.P.oN – Alarm power-on behavior

dE.oN – Time delay for Alarm trigger unless the condition persists, default = 1.0 s

dE.oF
"chatter," default = 0.0 s
Select the indicated setting.
7.3.1 Alarm Type (PRoG > ALM.1, ALM.2 > tyPE)
Select the Alarm Type (tyPE) parameter. This parameter will control the basic behavior of the
selected alarm.
Navigate to the desired setting. Settings include the following:

oFF

AboV – Alarm is triggered when the process value exceeds ALR.H (Absolute Mode)
or the specified Setpoint plus ALR.H (Deviation Mode)

bELo – Alarm is triggered when the process value is less than ALR.L (Absolute
Mode) or the specified Setpoint minus ALR.L (Deviation Mode)

HI.Lo. – Alarm is triggered when the process value is outside the ALR.L–ALR.H range
(Absolute Mode) or the range defined by the band around the specified Setpoint as
determined by ALR.L and ALR.H (Deviation Mode)

bANd – Alarm is triggered when the process value is within the ALR.L–ALR.H range
(Absolute Mode) or within the band around the specified Setpoint as determined by
ALR.L and ALR.H (Deviation Mode)
Note: Table 5.1 compares the Alarm range options, and Figure 5.1 represents the Alarm range
options graphically.
Select the indicated setting.
– Alarm type absolute or deviation
– Alarm low parameter, used for Alarm trigger calculations
– High High / Low Low offset value
– Alarm latching
