Disable local control switches by “nulling out” all the label settings for that switch (see
Section 9: Setting the SEL-351P Recloser Control
). The local bit associated with this disabled
local control switch is then fixed at logical 0.
Settings Examples
Local bits LB3 and LB4 are used in a few of the factory SEL
OGIC
Control Equation settings for
manual trip and close functions. Their corresponding local control switch position labels are set
to configure the switches as OFF/MOMENTARY switches:
