NOTES

NOTES:
1) If the alarm is programmed as band or deviation alarm, this

function masks the alarm condition after a set point change or
at the instrument start-up until process variable reaches the
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

- Alarm 3 type - [r.F09]

This parameter is available only when OUT 3 is configured as

Range: Proc = Alarm on process variable

bAnd = Band alarm on process variable
dEV

= Deviation alarm on process variable

ñAin = Alarm on Main control output value
SECn = Alarm on Secondary control output value

NOTE

NOTE: When alarm type has been changed the alarm threshold
will be forced to its default value and alarm status will be
cleared.
