GB
P26 = Alarm 1 action
Available only when P7 is equal to "al1.p" or
"al1.b" or "al1.d".
dir = direct action (relay energized in alarm
condition)
rEU = reverse action (relay de-energized in alarm
condition)
P27 = Alarm 1 stand-by function (mask)
Available only when P7 is equal to "al1.p" or
"al1.b" or "al1.d".
Off = stand-by function (mask alarm) disabled
ON = stand-by function (mask alarm) enabled
NOTE: 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 the 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 the process
variable reaches the alarm threshold plus or minus
hysteresis.
P28 = Action of the alarm 2 and 3
Available only when P9 or P11 are different from
"none".
dir = direct action (relay energized in alarm condi-
tion)
rEU = reverse action (relay de-energized in alarm
condition)
P29 = Alarm 2 stand-by function (mask)
Available only when P9 is different from "none".
OFF = Stand by (mask) disabled
On = Stand by (mask) enabled
P30 = Alarm 3 stand-by function (mask)
Available only when P11 is different from "none".
OFF = Stand by (mask) disabled
On = Stand by (mask) enabled
P31 = OFFSET applied to the measured value
This will set a constant OFFSET throughout the
readout range. It is skipped for linear inputs
- For readout ranges with decimal figure, P31 is
programmable from -19.9 to 19.9.
- For readout ranges without decimal figure, P31
is programmable from -199 to 199.
P32 = Displayable protected parameters
This parameter is skipped when P18 = 0.
Off = Protected parameters cannot be
displayed.
On = Protected parameter can be
displayed.
P33 = SMART function
O = SMART function disabled.
1 = SMART function in NOT protected by safety
lock.
2 = SMART function is under safety lock
protection.
