MORE THAN ONE REMOTE HI ON LINK
Problem: Noisy Communications link or a second Remote HI has
been installed on the link.
Check: Field/Unit wiring between Remote Human Interface and
the IPCB and RTM. Verify crimping of communications wiring.
There should be no loose connections or crimps on wire insulation.
Verify that no other Remote HI's have been connected to the same
communications link/unit.
MODULE SOFTWARE VERSION MISMATCH
PRESS CONFIG TO REVIEW, SEE LITERATURE
Problem: One or more control modules are installed that have a
version of software that does not match the required versions for
the installed features.
Check: Use the HI Configuration Menu to check the software
versions of the required modules. The ones that do not match will
have the word "INVALID" in the upper right corner of the screen.
Replace the software in those modules with the latest version.
