1 Technical Bulletin TB001680. Profile: General Data creation: March 2017. Wrote by: In some cases DEA 701 programming fails Approved by: & Revision: 01. Products involved: Platform: DW WIND. All DW platform WIND with mainboard DEA 701. S/N: All production What the technician observes: It is not possible to program DEA701 because of Communication Error appear. Root cause: To increase the security of the DEA 701, some modifications were done on the plastic box containing it. Because of these modifications, the pins of the hardware key COULD NOT CORRECTLY TOUCH the pads ON.

2 THE BOARD used to download the setting files. The pads on the mainboard are centered inside the window (see Picture 1) and, instead, it is necessary that they are NOT CENTERED (see Picture 2) or Technician is not using the right version of MemWriter. IMPORTANT: It is important to update the version of the MemWriter. It works since MemWriter PC ver.: and since MemWriter PDA ver.: RA_M_3_4_6__D_1_0_48. PC Link (in which to find the right version): PDA Link (in which to find the right version): Please, to be sure machine IS NOT CONNECTED ELECTRICALLY and IT IS EMPTY OF WATER before to start with some interventions or other operations in which the machine is open.

3 1. Technical Bulletin TB001680. Intervention to do: CASE 1: IF TECHNICIAN IS PROGRAMMING THE MAINBOARD ON THE APPLIANCE: If the technician during the mainboard programming or re-programming is facing an error with the Memwriter tool ( communication error see picture below), it is necessary to verify if the pins of the hardware key touch properly the pads on the board and if the version of MemWriter is last one. The technician must do a visual check of alignment between them; moreover the red led of the hardware key should be ON.

4 Steps to be followed: 1. disconnect the product from the mains. It is very IMPORTANT to work in safety conditions;. 2. open the front door where the mainboard is fixed;. 3. Move slightly (just a few millimeters) the mainboard (by unhooking it from the base), as if we wanted to remove it out; in so doing you will bring the contacts in the right position (Picture 2 - above);. 4. close the front door to avoid working under voltage;. 5. insert the hardware key ensuring that the pins touch the pads on the mainboard (DEA 701).

5 6. connect again the product to the mains. The RED led should be ON to indicate good contact;. 7. program the mainboard;. 8. after programming, disconnect the machine from the mains;. 9. extract the hardware key;. 10. open the front door;. 11. re-connect the mainboard (by hooking it again) in the original safety position;. 12. close the door. Please, to be sure machine IS NOT CONNECTED ELECTRICALLY and IT IS EMPTY OF WATER before to start with some interventions or other operations in which the machine is open.

6 2. Technical Bulletin TB001680. Intervention to do: CASE 2: PROGRAMMING ON THE BENCH: If the technician is trying to program the main board on the bench in the laboratory, the hardware key is supplied with the 12V, and if he will receive a communication error, it is necessary: to check if the pins of the hardware key touch properly the pads on the mainboard;. to suggest the technician to disconnect the 12V from the hardware key (the red led of the hardware key in this case is ON because the hardware key is powered with the 12V), and after that, to insert the mainboard in the appliance (the mainboard is supplied with the 220V), and follow the procedure details of Case 1 (above).

7 ADDITIONAL INFORMATION - IMPROVEMENT IN PRODUCTION: Large pads will be implemented in production starting from March 2017. After that, the problem should disappear. Please, to be sure machine IS NOT CONNECTED ELECTRICALLY and IT IS EMPTY OF WATER before to start with some interventions or other operations in which the machine is open. 3.
