7.3.2 Absolute or Deviation Alarm (PRoG > ALM.1, ALM.2 > tyPE >
Ab.dV)
Select the Absolute or Deviation Alarm (Ab.dV) parameter.
Navigate to the correct setting. Settings and sub settings include the following:

AbSo – Alarm is triggered using calculations based on the absolute values of ALR.H
or ALR.L used as specified by the tyPE parameter

d.SP1 – Alarm is triggered using calculations based on values relative to SP1 as
specified by the tyPE parameter

d.SP2 – Alarm is triggered using calculations based on values relative to SP2 as
specified by the tyPE parameter.

CN.SP – Alarm is triggered using calculations based on values relative to
instantaneous control setpoint generated by Ramp & Soak as specified by the tyPE
parameter.
Select the desired setting.
7.3.3 Alarm High Reference (PRoG > ALM.1, ALM.2 > tyPE > ALR.H)
Select the Alarm High Reference (ALR.H) parameter.
Set the Alarm High Reference value.
Confirm the value.
