P12 = Alarm 2 operating mode
Available only when P11 is equal to "AL2.P",
"AL2.b" or "AL2.d".
H.A. = High alarm (outside for band alarm) with
automatic reset (latched).
L.A. = Low alarm (inside for band alarm) with
automatic reset (latched).
H.L. = High alarm (outside band) with manual reset
(latched).
L.L. = low alarm (inside band) with manual reset
(latched).
P13 = Programmability of the alarm 2
threshold and hysteresis values
Available only when P11 is equal to "AL2.P",
"AL2.b" or "AL2.d".
OPrt =
Alarm 2 threshold and hysteresis are
programmable in the operating mode.
COnF = Alarm 2 threshold and hysteresis are
programmable in configuration mode.
P14 = Alarm 2 threshold value
Available only when P11 is equal to "AL2.P",
"AL2.b" or "AL2.d" and P13 is equal to "COnF".
Range: For process alarm - within the range
limits.
For band alarm - from 0 to 500 units.
For deviation alarm - from -500 to 500
units.
P15 = Alarm 2 hysteresis value
Available only when P11 is equal to "AL2.P",
"AL2.b" or "AL2.d" and P13 is equal to "COnF".
Range: from 0.1% to 10.0 % of the range selected
with P3 and P4 parameters, or 1 LSD.
P16 = Threshold of the “Soft Start” function.
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.
P17 = 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 manual reset of the
alarms) can be modified (for SMART status
see P30 parameter).
From 2 to 4999 = This combination number is a
secret value to be used, in run time (see nnn
parameter) to put the 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 P30).
From 5000 to 9999 = This combination number is
a secret value to be used, in run time (see
nnn parameter) to put the device in lock/
unlock condition.
For SP, SP2, manual reset of the alarm, AL1,
AL2, the lock/unlock condition has no effect
(for SMART status see P30).
NOTE:when safety lock is selected, the secret
value can not be displayed again and the
display will show 0, 1, SFt.A (when P17 is
encompassed between 2 and 4999) or SFt.b
(when P17 is encompassed between 5000
and 9999)
