P15 = Alarm 3 operative mode P15 = Alarm 3 operative mode P15 = Alarm 3 operative mode P15 = Alarm 3 operative mode 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 = P16 = P16 = P16 = P16 = Programmability of the alarm 3. Programmability of the alarm 3. Programmability of the alarm 3. Programmability of the alarm 3. 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 = P17 = Alarm 3 threshold value Alarm 3 threshold value
P17 = P17 = P17 = Alarm 3 threshold value Alarm 3 threshold value 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 = P18 = P18 = P18 = P18 = Alarm 3 hysteresis value Alarm 3 hysteresis value Alarm 3 hysteresis value Alarm 3 hysteresis value 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 P19= Soft Start threshold P19= Soft Start threshold
P19= Soft Start threshold 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 NOTE NOTE: this threshold value will not be taken into account
NOTE NOTE
when tOL = InF.
P20 = Safety lock P20 = Safety lock P20 = Safety lock P20 = Safety lock P20 = Safety lock
0 = No parameter protection. The device is always in
unlock condition and all parameters can be modified.
XKS-1-B0.pmd 12
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 NOTE NOTE NOTE 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 P21 = Alarm 1 action P21 = Alarm 1 action P21 = Alarm 1 action 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) P22 = Alarm 1 stand-by function (mask) P22 = Alarm 1 stand-by function (mask) P22 = Alarm 1 stand-by function (mask) 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 NOTE NOTE NOTE 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.
