Remote Seamless BYPASS Command Operation
A normally-open PLC contact, relay contact, or push-button contact may be
connected between TB1/14 and TB1/15. Close the contact to initiate an
automatic seamless bypass operation: CBB will close, then CBI and CBO will
open, removing power from the MegaDySC cabinets; voltage sag correction will
then be disabled.
This feature may be utilized as an Emergency Power Off (EPO) function for the
MegaDySC cabinets only. Power to the output loads or output distribution
panel, if present, will not be interrupted. Note that the automatic bypass
functionality requires that nominal AC power is present at the switchboard input
terminals.
