6.6.5 Phase Error during Operation (E.UPh)
The utilization of L1, L2 und L3 is compared with ru.13. If after triple scan-
ning (12 ms) a difference of >15 % of one phase to CP.13 is detected, then
• at ru.13 <50% a warning is triggered and switched off after 60 s, status
= E.UPh
• at ru.13 > 50 % is immediately switched off, status = E.UPh
