P6 = Out 2 configuration
P6 is skipped when P5 = 0.
If P5 = 1, 3 or 4;

H.A. =
High alarm with automatic reset

When P5 = 4, the "high" or "low" selection has no
effect.

When P5 = 5 this parameter selects the cooling
medium.

H2O = water
NOTE: Modifying parameter P6 automatically
updates the values of the cooling cycle time and
the cooling gain.

Air 10 (s) 1
OIL 4 (s) 0.8
H2O 2 (s) 0.4
P7 = Alarm 1 action
Only available when P5 is different from 0 or 5.
rEUrEU
rEUrEU
rEU = reverse (relay de-energized in alarm
condition)
dirdir
dirdir
dir = direct (relay energized in alarm condition)
P8 = Stand-by of the alarm 1
Only available when P5 is 1, 2 or 3.
OFFOFF
OFFOFF
OFF = stand-by disabled
ONON
ONON
ON = stand-by enabled
NOTE: For band or deviation alarm, the alarm
stand-by function disables the alarm indication at
instrument start up and after a set point
modification until the process variable reaches the
alarm threshold.
For process alarm, the stand-by function is
activated at start up only.
P9 = OFFSET applied to the measured value
This OFFSET is applied along the whole span.
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.
P10 = Threshold of the “Soft Start” function
The “Soft start” function limits the maximum out
power (see
OLHOLH
OLHOLH
OLH operative parameter) for a
programmable time (see
tOLtOL
tOLtOL
tOL operative parameter)
at the instrument start up when the measured
value is lower then the programmed threshold.
P10 is the threshold value, in engineering units.
Changing P1 parameter value, P10 parameter will
be forced to the minimum range value of the new
selected range.
