Issue:
What are the the contacts labelled KM1 and KM2 feeding into the IC1 forward contactor and IC2 reverse contactor?
Product line:
Altistart 48, ATS48
Environment:
All enclosed
Cause:
Typo error in the instruction bulletin
Resolution:
This is an error in the manual. KM1 should be labelled IC1 and KM2 should be labelled IC2.
These are auxiliary contacts from the forward and reverse isolation contactors, used for electrical interlocking. This helps prevent closure of both contactors at the same time.
