7.6.2 Display management
This instrument allows to program (see parameter [92] diS.t
the time out of the display.
This function allows to turn OFF the display when no alarm
is present and no action is made on the instrument.
When [92] diS.t is different from OFF (display always ON)
and no button is pressed for more than the programmed time
out, the display goes OFF and only the four segments of the
less significant digit are turned ON in sequence in order to
show that the instrument is working correctly.
If an alarm occurs or a button is pressed, the display returns
to normal operation.
7.6.3 Display Colour Shows the Deviation
This instrument allows to program the deviation (PV - SP) for
colour display change (see parameter [123] AdE).
In this way the upper display colour will be:
–
Amber when PV is lower than SP - AdE;
–
Green when (SP - AdE) < PV < SP + AdE);
–
Red when PV is higher than SP + AdE.
8 THE PROGRAM FUNCTIONS
8.1 How to Edit (create or modify) a
program
Preliminary note
: As already described, the parameters
available at operator level (but also at limited access level)
are divided into two parameter “families”.
Each Program parameters family is divided in 5 groups
(
PrG
,
Pr1
,
Pr2
,
Pr3
and
Pr4
or
PrG
,
Pr5
,
Pr6
,
Pr7
and
Pr8
). The first one (PrG) includes the parameter necessary
to manage the program running (or to select the program to
run), while the other includes all editing parameters related
with a specific program (Pr1 for program 1, etc.).
These instruments are equipped with 8 programs divided
into 2 pages of 4 programs each.
For this reason we have Program 1 to program 4 when page
1 is selected and Program 5 to 8 when page 2 is selected.
To select a program:
–
Enter in PrG group:
–
Select the desired “page”;
–
Select the desired “program”.

PrG Group - Programmer function parameters
[126] PAGE - Selection of the active program page
Available:
Always.
Range:
1 or 2
Note:
During program execution this parameter can NOT be
changed.
[127] Pr.n - Active program
Available:
Always.
Range:
From 1 to 8.
Note:
During program execution this parameter can NOT be
changed.
[128] Pr.St - Status of the active program
Available:
Always.
Range:
rES
Program reset;
run
Program Start;
HoLd
Program Hold;
cnt
Continue (read only).
When is necessary to edit a program, proceed as follows:
The instrument is showing the “standard display”.

).
11.
Press the
button.
Note:
In the following pages we use Program 1 as example.
]
Pr1 Group - Program 1
[129] P1.F - Program 1 action at power up
Available:
Always:
Range:
nonE
Program not used;
S.uP.d Start at power up with a first step in stand by;
S.uP.S Start at power up;
u.diG
Start at RUN command detection only;
U.dG.d Start at RUN command detection with a
first step in stand by.
[130] P1.u - Time unit of the soaks
Available:
When [129] P1.F is different from
nonE
.
Range:
hh.nn
Hours and minutes;
nn.SS= Minutes and seconds.
Note:
During program execution, this parameter can not be
changed.
[131] P1.E - Instrument behaviour at End of
program 1 execution
Available:
When [129] P1.F is different from
nonE.
Range:
cnt
Continue (the instrument uses the set point
of the last soak until a reset command is
detected);
SPAt
Go to the set point selected by [81] A.SP
parameter;
St.bY
Go in stand by mode.
Notes: 1.
Setting [131] P1.E = cnt at program end the
instrument uses the set point of the last soak.
When a reset command is detected it will go to
the set point selected by [81] A.SP parameter.
2.
Setting [131] P1.E = SPAt at program end the
instrument goes to the set point selected by
[81] A.SP parameter. The transfer will be a
step transfer or a ramp according to the [84]
SP.u (maximum rate of rise for positive set point
change) and [85] SPd (maximum rate of rise for
