P15 = Alarm 3 operative mode
Available only when P14 is different from 0.
H.A. = High alarm (outside for band alarm) with

automatic reset.

L.A. =

Low alarm (inside for band alarm) with automatic
reset.

H.L. =

High alarm (outside band) with manual reset
(latched alarm).

L.L. =

low alarm (inside band) with manual reset
(latched alarm).

P16 =

Programmability of the alarm 3.

Available only when P14 is different from 0.
OPrt =

Alarm 3 threshold and hysteresis are
programmable in operating mode.

COnF =

Alarm 3 threshold and hysteresis are
programmable in configuration mode.

P17 =

Alarm 3 threshold value

Available only when P14 is different from 0 and P16 is
equal to "COnF".
Range:
- For process alarm

- within the span limits (P4 - P3)

- For band alarm

- from 0 to 500 units.

- For deviation alarm

- from -500 to 500 units.

P18 =

Alarm 3 hysteresis value

Available only when P14 is different from 0 and P16 is
equal to "COnF".
Range: from 0.1% to 10.0 % of the span (P4 - P3)

P19= Soft Start threshold
Threshold value, in eng. units, to initiate the "Soft start"
function (output power limiting) at start up.
Range: within the readout span.
NOTE: this threshold value will not be taken into account
when tOL = InF.

P20 = Safety lock
0 =

No parameter protection. The device is always in
unlock condition and all parameters can be modified.

1 =

The device is always in lock condition and no one of
the parameters (exception made for set points [SP,
SP2] and alarm manual reset) can be modified (for
SMART status see P31 parameter).

From 2 to 4999 =

This combination number is a secret

value to be used, in run time (see nnn parameter) to
put device in lock/unlock condition.
For SP, SP2 and manual reset of the alarms, the
lock/unlock condition has no effect (for SMART
status see P31).

From 5000 to 9999 = This combination number is a secret

value to be used, in run time (see nnn parameter) to
put device in lock/unlock condition.
For SP, SP2, manual reset of the alarm, AL1, AL2,
AL3, Hbd and SCA, the lock/unlock condition has no
effect (for SMART status see P31).

NOTE: when safety lock is selected, the secret value can
not be displayed anymore and the display will show 0, 1,
SFt.A (when P20 is encompassed between 2 and 4999)
or SFt.b (when P20 is encompassed between 5000 and
9999)

P21 = Alarm 1 action
Available only when P7 is different from 0 or 4.
dir

= direct action (relay energized in alarm condition)

rEV = reverse action (relay de-energized in alarm

condition)

P22 = Alarm 1 stand-by function (mask)
Available only when P7 is different from 0 or 4.
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 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.
