- Alarm 3 standby (mask) function - [r.F12]
This parameter is available only when OUT 3 is configured as
alarm 3 output (“O3.Fn” [C.E03] = “ALr.3”)
Range: OFF = Stand-by function disabled
On = Stand-by function enabled
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 4 type - [r.F13]
This parameter is available only when OUT 4 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

will be forced to its default value and alarm status will be
cleared.
