Hi folks,
We've come across an issue in the field with the PPS when used with an external voltage regulator (the LR3C). There is no problem with the EVR at all, but there is a wiring change that has been updated in both the VP-X and the PPS manuals. Failure to either change your wiring, or wire when installing using this revision will potentially damage the PPS.
There is no safety of flight issue, but the damage would occur when either starting up, or shutting down. The voltage regulator MUST be shut off BEFORE the alternator, or at the same time when shutting down, or the alternator MUST be turned on BEFORE the EVR when starting up.
Revision E is now current for both manuals, and both are available here-

If you have a PPS please get the revised manual whether you have a VP-X or not, but there are new sections covering use of the LR3C with the PPS in a VP-X system, and a traditional buss system.
Cheers,
Chad
