0 = Not provided
1 = Process alarm
2 = Band alarm
3 = Deviation alarm
4 = instrument failure indicator
5 = cooling output (LHS only)
NOTE NOTE NOTE NOTE NOTE: for the model LHS, when P5 = 5 the P4
parameter is forced to "r".
P6 = Output 2 operative mode. P6 = Output 2 operative mode. P6 = Output 2 operative mode. P6 = Output 2 operative mode. P6 = Output 2 operative mode.
P6 is available only when P5 is different from 0.
When P5 = 1,2 or 3
H.A = high alarm (outside band) with automatic
reset
L.A = low alarm (inside band) with automatic reset
H.L= high alarm (outside band) with manual reset
L.AL= low alarm (inside band) with manual reset
When P5 = 4 theselections H.A and L.A show an
instrument failure indicator with automatic reset
while the H.L and L.L selections show an instrument
failure indicator with manual reset.

When P5=5 (LHS only) this parameter selects the
cooling medium. AIr = Air
OIL = Oil
H2O = Water
NOTE NOTE NOTE NOTE: different set of cooling medium produce NOTE
the automatic modification of the relative cooling
gain and of the cooling cycle time.

P7 = Alarm action P7 = Alarm action P7 = Alarm action P7 = Alarm action P7 = Alarm action
Available only when P5 is different from 0 or 5.
r = reverse (relay de-energized in alarm condition)
d = direct (relay energized in alarm condition)
P8 = Stand by of the alarm P8 = Stand by of the alarm P8 = Stand by of the alarm P8 = Stand by of the alarm P8 = Stand by of the alarm
Available only when P5 is different from 0,4 or 5.
OFF = stand by disabled
ON = stand by enabled
NOTE: the alarm stand by function allows to NOTE NOTE NOTE NOTE
disable the alarm indication at instrument start up
and/or after a set point modification until the
process variable reach the alarm threshold.
P9 = OFFSET applied to the measured value P9 = OFFSET applied to the measured value P9 = OFFSET applied to the measured value P9 = OFFSET applied to the measured value P9 = OFFSET applied to the measured value
This OFFSET is applied along the whole range.
When P1= 5 P9 is programmable from -19.9
to 19.9 °C.
When P1 ≠ 5
P9 is programmable from -199
to 199 °C or °F.
