2.45 Production data
Production data is information to enable a device to be traced. The behaviour of the fan is not influenced by
these parameters.
2.45.1 Fan serial number and production date
Address of serial number : D1A2 / D1A3
Address of production date : D1A4
Write authorisation : ebm-papst
For each fan, ebm-papst assigns an individual serial number. This serial number has 10 digits.
Format: YYWW00XXXX
YY : Production year
WW : Calendar week of production
00 : Fixed value 00
XXXX : Sequential number
The first 4 digits contain the production date (year/calendar week).
With the beginning of each production week, the number XXXX starts counting up from zero and is increased
by 1 for each fan. Each character can represent values from 0-9 and from A-Z. The maximum number of
characters that can be encoded for each digit is thus 36, i.e. 36
4
= 1 679 616 devices/week.
