Regarding the selector switch of LCS of 19sets that are already at site, I have discussed with Mr. Witawit, PTTLNG engineer and he agreed to use break-before-make. Thus, it does not need to be modified.
However, 3sets which are provided to OVIVO shall be make-before-break type selector switch. Please deal with this issue with OVIVO.
Best regards,
