Thanks very much for replying, Charles.

I've done a bit more investigating. I added a diagnostic
printf("%x",
ups_status) at the point where LB is set. It shows that it's
RemainingTimeLimitExpired that's causing the LB condition. Below is a
bit more of the driver log which shows RemainingTimeLimitExpired
changing to 1 and then back to 0 again. What does that variable mean?

Thanks again for your help,
