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, 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
