PAG. 14
The third zone has a local set point equal to -45 (°C).
The fourth zone has a local set point equal to -30.
The fifth zone has a local set point equal to +40.
The sixth zone has a local set point equal to +50.
In this way, the thermal profile will be the following:
–
Master SP = 210°C;
–
Second zone SP = 210 -45 = 165°C;
–
Third zone SP = 210 -45 = 165°C;
–
Fourth zone SP = 210 - 30 = 180°C;
–
Fifth zone SP = 210 + 40 = 250°C;
–
Sixth zone SP = 210 + 50 = 260°C.
Changing the SP of the master unit, all the other slave units
will immediately change their operative set point.
[69] SP.Lr - Local/remote set point selection
Available:
Always.
range:
Loc =
Local set point selected by [67] A.SP;
rEn =
Remote set point (coming from serial link).
[70] SP.u - Rate of rise for positive set point change
(ramp up)
Available:
Always.
range:
0.01... 99.99 units per minute;
inF = Ramp disabled (step transfer).
[71] SP.d - Rate of rise for negative set point change
(ramp down)
Available:
Always.
range:
0.01... 99.99 units per minute;
inF =
Ramp disabled (step transfer).
General note about remote set point:
When the remote set point (RSP) with trim action is
programmed, the local set point range becomes:
from [61] SPLL + RSP to [62] SPHL - RSP.

[72] PAS2 - Level 2 password: Limited access level
Available:
Always.
range:
oFF = Level 2 not protected by password
(as level 1 = Operator level);
1... 200.
[73] PAS3 - Level 3 password:
Complete configuration level
Available:
Always.
range:
3... 200.
note:
Setting [72] PAS2 equal to [73] PAS3, the level 2 will
be masked.
[74] uSrb -
button function during RUN TIME
Available:
Always.
range:
nonE = No function;
tunE = Auto-tune/self-tune enabling. A single
press (longer than 1 s) starts the auto-tune;
oPLo = Manual mode. The first pressure puts the
instrument in manual mode (oPLo) while the
second one puts the instrument in Auto mode;
AAc = Alarm reset;
ASi =
Alarm acknowledge;
St.by = Stand by mode. The first press puts the in-
strument in stand by mode while a second
one puts the instrument in Auto mode;
SP1.2 = SP/SP2 selection.
notes: 1.
When “SP1.2” is used, every press of the
button (longer than 1 second) switches the
selected set point.
Changing the set point using the
key, the
display shows for 2 seconds the acronym of the
new set point (SP1 or SP2).
2.
To use “SP1.2” selection, the [60] nSP parameter
must be equal to 2.
[75] diSP - Middle Display Management
Available:
Always.
range:
nonE = Display not used;
SPF = Final set point;
SPo = Operative set point;
AL1 = Alarm 1 threshold;
AL2 = Alarm 2 threshold;
Po = Power output.
[76] di.cL - Display colour
Available:
Always.
range: 0
The display colour is used to show the actual
deviation (PV - SP);
1
Display red (fix);
2
Display green (fix);
3
Display orange (fix).
[77] AdE - Deviation for display colour management
Available:
When [123] di.cL = 0.
range:
1... 9999 engineering units.
[78] diS.t - Display time out
Available:
Always.
range:
oFF = The display is steady ON;
0.1... 99.59 minutes and seconds.
note:
This function allows to turn OFF the display when no
alarm is present and no action is made on the instrument.
When diS.t is different from oFF and no button is
pressed, at the end of the programmed time out, the
display goes OFF and only the four segments of the
least significant digit are turned ON in sequence to
show that the instrument is operating.
If an alarm occurs or a key is pressed, the display
returns to normal operation.
[79] FiLd - Filter on the displayed value
Available:
Always.
range:
oFF = Filter disabled;
1... 100 engineering units.
note:
This is a “window filter” related to the set point, it is ap-
plied to the displayed value only and has no effect on the
other functions of the instrument (control, alarms, etc.).
[80] dSPu - Status of the instrument at power up
Available:
Always.
range:
AS.Pr = Starts in the same way it was prior to the
power down;
Auto = Starts in Auto mode;
oP.0 = Starts in manual mode with a power output
equal to zero.
St.bY = Starts in stand-by mode
note:
When the user changes the value of [81] oPr.E, the
instrument forces parameter [82] oPEr = Auto.
