Legacy WC and Mini Bar I/O Board
TPA# 20-001
Issued By: Bryan Mather
Date: September 2020
This TPA is for general informational purposes only. No action is required.
AFFECTED PRODUCTS:
- Legacy SOLO/DUO/TRIO WeCan lightbars
- Mini Bar: Legacy
BACKGROUND:
As Whelen works to continually improve its products and process flow of materials, an engineering design change was made to the Legacy WeCan Lightbar Input/Output (I/O) board. This change also impacts the mini Legacy lightbars
ISSUE:
Customers who need to order a replacement I/O board for the WeCan Legacy SOLO, DUO, or TRIO lightbars will need to identify which revision of the I/O board they currently have. In early 2020 a new I/O board was put into production. This I/O board is physically smaller and has a different wiring harness and I/O connections.
Customers who simply check a current WeCan Legacy or Mini Legacy bill of materials (BOM) and order a replacement I/O board off that BOM may receive the incorrect I/O board for that revision.
SOLUTION:
When a replacement I/O board is required please consult with the Technical Support Group (TSG), or verify the I/O part number contained within the lightbar.
For assistance in determining which I/O board is in your WeCan Legacy lightbar or Legacy Mini lightbar please contact the Technical Support Group.
