Logic Diagram for Dynamic Cold Load Pickup Feature
Dynamic cold load Pickup feature can only be enabled if address &ROGORDG
3LFNXS was set to (QDEOHG during configuration of protective functions. If the func-
tion is not required, address should be set to 'LVDEOHG.
There are no specific procedures on how to set the time delays at addresses &%
2SHQ 7LPH, $FWLYH 7LPH and 6WRS 7LPH. These time delays must be
based on the specific loading characteristics of the equipment being protected, and
should be selected to allow the brief overloads associated with dynamic cold load con-
ditions.
