alarm threshold plus or minus hysteresis. If the alarm is
programmed as a process alarm or control output alarm, this
function masks the alarm condition at instrument start-up until
process variable reaches the alarm threshold plus or minus
hysteresis.
2) The change from On to OFF has immediate effect, while the
change from OFF to On has effect at the next start up or set
point change
- OFD (Output Failure Detection) alarm
configuration - [r.F17]
This parameter is available only when OFD option is configured
(“Fd.Fn” [C.I11] is different from "nOnE").
Range: A.
= Alarm with automatic reset
A.Ac = Alarm with automatic reset and acknowledge
L.
= Alarm with manual reset
NOTE: When alarm configuration has been changed, the alarm
status will be deleted.
- OFD (Output Failure Detection) alarm action
- [r.F18]
This parameter is available only when one output is configured
as OFD alarm annunciator (“Fd.Fn” [C.I11] and “Fd.Ou” [C.I13]
are different from “nonE”).
Range: dir
= direct action (Relay energized or SSr=1 in
alarm condition)
rEV = Reverse action (Relay energized or SSr=1 in
non alarm condition)
NOTE: When OFD output is in OR condition with an alarm or an
event output, the “Fd.Ac” parameter can only be monitored but
not modified and it assumes the same action defined (by “Alarm
Action” or “Event Logic Level”) for the alarm or the event.
- Group 6 default data loading - [r.F19]
Range: OFF = No loading data
ON = Loading data
