P20 = Security code for run time parameters
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, SP3, SP4 and alarm manual reset) can be
modified (for SMART status see P35 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 the four set points and manual reset of the alarms,
the lock/unlock condition has no effect (for SMART
status see P35).
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 the four set points, AL1, AL2, AL3 and manual
reset of the alarms, the lock/unlock condition has no
effect (for SMART status see P35).
NOTE:when safety lock is selected, the secret value can
not be displayed again 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 = Power output of the main control output
This parameter is skipped when no one of the output is
configured as control output.
norL = the power output assigned to the main control
output is the result of the PID algorithm.
cñPL = the power output assigned to the main control
output is the complement of the PID result (100 -
value calculated by PID algorithm).
P22 = Power output displayed for the main control
output.
This parameter is skipped when no one of the output is
configured as control output.
norL = the display will show the result of the PID
algorithm calculated for the main control output.
cñPL= the display will show the complement to the result
of the PID algorithm calculated for the main
control output (100 - value calculated by PID
algorithm).
P15 = Alarm 3 operative mode
Available only when P14 = AL3.P, AL3.b or AL3.d or P51=Enb
or EnbO.
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).
L.L. = low alarm (inside band ) with manual
reset(latched).
NOTE: The Loop break alarm assumes the same alarm
reset type selected with P15 parameter.
P16 = Programmability of the alarm 3.
Available only when P14 = AL3.P, AL3.b or AL3.d.
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 = AL3.P, AL3.b or AL3.d and
P16 = COnF.
Range:
For process alarm - within the range limits (P3 -
P4).
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 = AL3.P, AL3.b or AL3.d and
P16 = COnF..
Range: from 0.1% to 10.0 % of the span selected with P3
and P4 parameters or 1LSD.
P19 = 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.
NOTES:
1) This threshold value will not be taken into account
when tOL = InF (power limiting ever active).
2) When it is desired to disable the soft start function, set
P19 equal to the lower readout value or set the OLH
parameter equal to 100.0% (no power limiting).
