8.3 How to Link two (or more)
programs
Program linking can give you more advantages:
A)
When you need a program with more than 12 segments
you can link the selected program with the next one.
In this way it is possible to obtain “profile” with 24, 36 or
48 steps.
B)
Another reason is the possibility to use different time
bases in the same “profile”.
C)
When you link more programs you can start the execution
from the desired one.
E.g.: To link Pr1 (pre-heat with 1 execution only), Pr2 (first
part of a heat treatment with 4 executions) and Pr3 (second
part of the heat treatment with 2 executions), you can:
I)
RUN program 1; the instrument performs in sequence
Pr1, Pr2 and Pr3; One time only.
II)
RUN program 2; the instrument performs Pr2 and Pr3
Pr4 times before ending.
III)
RUN program 3; the instrument will perform Pr3 2
times before ending.
In a realistic application example the pre-heat phase is
important at power up only (aimed to reduces the thermal
stress of the oven during start up). For this reason you can
program Pr1 for start at power up (at power up the instrument
will perform all phases) and then all next treatments of the
day will be made running Pr2 (with 1 execution only).
In the following example we create a profile using a Pre-heat
of 4 segment and a treatment phase using 18 segments
Now we can built the profile proceeding as follows:
1.
Select Page 1;
2.
Select the Program 1;
3.
Set the desired RUN type (P1.F = S.UP.S);
4.
Set the first time base (P1.u = mm.SS);
5.
Set the desired program end (e.g. P1.E = A.SP);
6.
Set the desired execution number (P1 nE = 1);
7.
Set the first 2 groups of parameters (2 ramps and 2 soaks).
Now, the pre-heat phase is finished.
8.
End this phase by setting the next parameter (P1.S3)
equal to OFF (P1.S3 = OFF);
The instrument will mask all parameters of the Pr1 after
P1.S3 exception made for the parameter P1.c2 (program 1
continue on program 2.
9.
Set P1.C2 equal to YES;
10.
Press the
button until Pr2 is shown;
11.
Enter in Pr2;
12.
Set the specific RUN type (P2.F = U.diG);
13.
Set the time base (P2.u = hh.nn);
14.
Set the program end (P2.E = A.SP);
15.
Set the execution number (P2 nE = 1);
16.
Set the all segments (6 ramps and 6 soaks);
17.
Set P2.C3 equal to YES (continue on Pr3);
18.
Press the
button until Pr3 is shown;
19.
Enter in Pr3;
20.
Set the specific RUN type (e.g. P3.F = U.diG);
21.
Set the time base (P3.u = hh.nn);
22.
Set the desired program end (P3.E = A.SP);
23.
Set the execution number (P3 nE = 1);
24.
Set all necessary segments (3 ramps and 3 soaks).
Now, the treatment phases is finished.
25.
End this phase by setting the next parameter (P3.S4)
equal to OFF (P3.S4 = OFF);
26.
Set P3.C4 equal to no (do NOT continue on Pr4);
27.
Set USrb (function of the
button) equal to P.run.
Now you can set Page = 1, set Pr.n = 1 (Program 1), turn
off the ovens and load it with the first set of objects to be
treated during the next day.
The next day you can turn on the oven; the instrument will
perform the pre-heat and the complete treatment of the material.
At the end of the treatment the oven operates according to P3.E
setting (in our example it maintains the temperature set by SP).
Remove the material already treated.
Load a new set.
Set Pr.n =2 (Program 2);
Push the
button.
The instrument will perform only the complete treatment (Pr2
followed by Pr3) of the material.
8.4 How to Run a program
The Run command can be sent to the instrument by:
–
[128] Pr.St parameter (= run);
–
button (when [88] U.Srb = P.run or P.r.H.r);
–
Digital input (when [10] diF1 = 6, 9, 10 or [11] diF2 = 6,9,10).
–
By serial link,
Note:
The decimal point of the LSD of the lower display is
used to show the programmer status independently
from the displayed value selected by [121] diSP
(Display management).
Decimal point
of the LSD
The relation between the programmer status and the
LED are the following:
• Program in RUN - the LED is ON;
• Program in Hold - The LED is flashing fast;
• Program in wait - The LED is flashing slow;
• Program in end or reset - The LED is OFF.
8.5 How to Hold a program
This function temporarily stops a running program by a
manual action.
When the program is in hold, the set point updating and time
count are stopped and the instrument operates as controller
with fixed set point.
The HOLD mode may be activated:
–
Setting [128] Pr.St parameter (= HoLd);
–
A short pressure of the
button (when USrb = P.r.H.r);
–
By digital input (when [10] diF1 = 8, 9 or [11] diF2 = 8, 9);
–
By serial link.
When a program is in Hold, the decimal point of the LSD of
the lower display flashes fast.
When the lower display is programmed to show informations
related with program running (diSP = Pr.tu, Pr.td, P.t.td or
P.t.tu) the lower display will flash at the same “speed” of the
