Fail-safe activation condition
Description
Defines the condition the fail-safe behaviour of the channel becomes active and determines
the channel availability.
Invalid process value; Maintenance alarm or Failure (NAMUR)

Setup → Inputs and outputs → Channel 1 - output with HART → Fail-safe activation condi-
Damping value
Description
Sets the Damping (filtering) to smooth out response to sudden changes in measurement.
An increase to Damping value increases response time of device, and affects digital value
and loop current. If output values are noisy, increase Damping value. For faster response
time, decrease Damping value. Find a value that meets requirements of signal stability and
response time.
Setup → Inputs and outputs → Channel 1 - output with HART → Damping value
Fail-safe behaviour
Description
Defines behaviour when Fail-safe is initiated.
Lower fault current; Upper fault current; Last valid value; Current value; Fail-safe value
Setup → Inputs and outputs → Channel 1 - output with HART → Fail-safe behaviour
