ATTENTION TO REVISION NUMBER DURING
SERVICING
®
The VLT Advanced Harmonic Filter AHF 005/AHF 010
program is constantly optimized, introducing differences
between the individual designs. Vital differences are
managed through revision control of the individual
designs.
Differences between the individual revisions can lead to
different spare parts. It is important to select matching
spare parts according to the revision number of the
actual filter.
The spare part selection tables include a reference to the
matching revision number in the AHF serial number
string.
The specific revision number is identified in the serial
number string of the AHF listed on the nameplate of the
actual filter. Characters 5 and 6 in the serial number
string are the identifiers of the revision number.
Since the introduction of the AHF program, the following
revisions have been introduced:
•
01
•
02
•
03
The current version, featuring variable speed fan, is
identified by revision number 03.
Example:
SN: 0100 03 - 378
Characters 5 and 6 are 03, confirming that this is revision
number 03.
