8.3.4 Procedure B
1. Note the serial number of the set
example:
VN050136130156
• VN = production centre (VN....Szekesfehervar).
According to UAW-500: V=22 and N=14
• 05 = change code (this is not used for this
calculation)
• 01 = YEAR
• 36 = Production WEEK
• 130156 = Lot and SERIAL number
2. Calculate the unique number: this number always exists
out of 10 hexadecimal numbers.
3.
First 5 numbers:
First we calculate a decimal number according to the
formula below:
35828 *
YEAR
+ 676 *
WEEK
+ 26 *V + N + 8788
The figures are fixed,
YEAR + WEEK + factory code ( V
+ N) are variable
Example:
35828 *
01
+ 676 *
36
+ 26 *22+14+ 8788 = 69538 (decimal)
Then we translate the decimal number to a hexadecimal
number.
example:
69538 (decimal) = 10FA2 (hex)
4. Last 5 numbers:
The last 5 numbers exist out of the Lot and SERIAL
number.
We have to translate the decimal number to the next 5
hexadecimal numbers:
Example:
130156 (decimal) = 1FC6C (hex)
5. Program new digital board via nucleus 410
Therefore we use the 10 hexadecimal numbers we
calculated above:
example:
DD:> 410 10D7A1FC6C
41000:
Test OK @
The set has now its original unique number
