[121] uSrb -

button function during RUN TIME

Available:

Always.

Range:

nonE = No function;
tunE = Auto-tune/self-tune enabling. A single

press (longer than 1) starts the auto-tune;

oPLo = Manual mode. The first pressure puts the

instrument in manual mode (OPLO) while a
second one puts the instrument in Auto mode;

AAc = Alarm reset;
ASi =

Alarm acknowledge;

chSP = Sequential set point selection (note);
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;

Str.t =  Reserved;
P.run =  Reserved;
P.rES =  Reserved;
P.r.H.r =  Reserved.

Notes: 1.

When “

Sequential set point selection

” is used,

every press of the

button (longer than 1

second) increase the value of A.SP (active set
point) of one step.
The selection is cyclic: SP -> SP2 -> SP3 -> SP4

When a new set point is selected using the

key, the display will show for 2 seconds the

acronym of the new set point (e.g. SP2).

When “

Sequential set point selection

” is used, the

number of set points selectable is limited by [74] nSP.

[122] diSP - Display management

Available:

Always.

Range:

nonE =  Standard display;
Pou =  Power output;
SPF =  Final set point;
SPo =  Operative set point;
AL1 =  Alarm 1 threshold;
AL2 =  Alarm 2 threshold;
AL3 =  Alarm 3 threshold;;
Pr.tu =  Reserved;
Pr.td =  Reserved;
P.t.tu =  Reserved;
P.t.td =  Reserved;
ti.uP =  Reserved;
ti.du =  Reserved;
PErc =  Percent of the power output used during soft

start (when the soft start time is equal to
infinite, the limit is ever active and it can be
used also when ON/OFF control is selected);

PoS = Reserved.

[123] 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).

[124] AdE - Deviation for display colour management

Available:

When [123] di.CL = 0.

Range:

1 to 9999 engineering units.

[125] diS.t - Display time out

Available:

Always.

Range:

oFF = The display is ever ON;
0.1 to 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 for more than the programmed time out, the
display goes OFF and only 4 segments of the less
significant digit are turned ON in sequence in order to
show that the instrument is working correctly.
If an alarm occures or a buton is pressed, the display
will come back to the normal operation.

[126] FiLd - Filter on the displayed value

Available:

Always.

Range:

oFF = Filter disabled;
From 0.0 (oFF) to 20.0 engineering units.

Note:

This is a “window filter” related to the set point; it is
applied to the displayed value only and it have no
effect on the other functions of the instrument (control,
alarms, etc.).

[128] 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

Notes: 1.

When you change the value of [129] oPr.E, the
instrument forces [130] oPEr parameter to Auto.

If the “[128] dSPu” parameter is different from
