Replacement Advisory
2020 Logic Control Board
This logic control board has been redesigned. The new board design can be
easily distinguished from the early board design by comparing the type of
connectors used for J1 (Battery) and J5 (Charger). The new boards use different
hardware at these points (see illustration on the reverse of this page).
When replacing the logic control board in an existing system, the installer must
make sure that all wires connecting to the new board maintain the same
orientation as shown on the back of this sheet.
Outdoor Warning
If the orientation of any connectors do not match the orientation shown, do not
plug these connectors into the replacement board! Contact Whelen
Customer Service immediately.
