3. Insert the key into the corresponding slot.  

4. Press Up and Down together in the display and switch the board on. 
5. Check that the red key LED comes on. 
6. Wait until the upload request is displayed on the LCD, then release the buttons and confirm  by pressing 
Enter; the data transfer operation will take approximately 10 seconds. 
7. Switch the pCO1 off, remove the key, place the cover in its original position and switch the board back on 
again. 
8. The board will now work with the program transferred from the key. 
 

 

4.3.2  Program download from computer 

 
Use the the converter (RS232/RS485) and the WinLOAD 32 program, proceeding as follows: 
1. Connect the converter (RS232/RS485) to the mains using the transformer provided in the kit. 
2. Connect the converter to a free serial port on the PC, using the serial cable provided in the kit. 
3. Connect the converter to connector J10 on the pCO1 using a telephone cable. 
4. Install Winload, if Winload is not already installed on the PC. 
5. Run WinLOAD32 on the PC, with the board off. 
6. Enter in the number of the PC seri

al port in the field “COMM” (1 for COM1, 2 for COM2)

7. Enter “0” in the field “pCO ADD.”

8. Switch the board on. 

9. Wait 30 seconds until the message “OFF LINE” becomes “ON LINE” in the WinLOAD32 program, in the 

lower  left,  or  until  the  yellow  LED  next  to  the  dipswitch  on  the  board  starts  flashing;  now  enter  the  actual 
board LAN

 address value in the field “pCO²

 

ADD”; a blue light in the Winload program, in the bottom centre 

of the window, will start flashing. 

10. In WinLOAD32, select “Upload” and then “Application”

11. Select the folder containing the application program source files. 
12.  Use  CTRL  to  select  a  series  of  *.iup  files,  if  needing  to  load  a  series  of  languages  to  the  pCO1.  Also 
select  the  *.blb  files  (for  non-LAN  applications)  or  the  flash1.bin  file  in  the  program  being  loaded  (for  LAN 
applications). 

13.  Click  “UPLOAD”  to  start  the  file  download  procedure,  which  will  take  approximately  1  to  5  minutes, 

depending on the number of *.iup files selected and the size of the various files. 
14. Wait u

ntil the message “Upload OK” appears in the progress bar

15.  Disconnect  the  telephone  cable  between  the  board  and  converter;  connect  the  external  display  (if 
featured), then switch the board off and on again. 

 
NOTE

:  if  a  LAN  network  with  a series of  boards is  used,  the  program  can  be  installed  on  the  other  boards 

without repeating the operations: after installing the program on the first board, simply repeat steps from 8 to 
14, entering the new board addres

ses each time in the field “pCO ADD” in the WinLOA

D32 program. 

4.3.3  Restore the default parameters 

 

Default  parameters  are  the  values  assigned  by  manufacturer  to  the  application  program  main  operative 
parameters.  Parameters  are  assigned  automatically  when  executing  the  DOWNLOAD  operation  as 
described  above.  Pa

rameters  indicate  timing,  set  points,  differentials,  etc…  (refer  to  the  complete  list  of 

default values). 
After installing  default values, the parameters  must be  modified following the special parameter list with the 
specific parameter of the installed unit. 
Operations to be carried out for default parameters manual installation: 
1. Push buttons PRG + ESC keys and type the Manufacturer password, then push Enter. 

2. By pushing button Down three times, move the cursor on “INI

TIALIZ

ATION” (last row), then push

 ENTER. 

3.  The  parameters  installation  screen  is  displayed;  to  install,  push  ENTER  and  type  the  Manufacturer 
password. 
4. 

WARNING: 

we recommend extreme care since this operation deletes all the installed parameters from the 

memory and replaces them by the default parameters 

 after this operation, parameters cannot be restored. 

5. After pushing ENTER, message “PLEASE WAIT” is displayed for some seconds.

 

6. Switch off and then switch on the power supply.
