The UDP function allows the Form 5 control to become a
switch control to provide indication of overcurrent trip con-
ditions without issuing an overcurrent trip signal. The con-
trol is in the recloser mode when the feature is in the OFF
position, and in the switch mode when the feature is
ACTIVE.
While in the switch mode, all automatic open and close
operations of the recloser (including overcurrent voltage
and frequency) are blocked. Fault targeting, metering,
alarms, and event recording functions are active.
This non-tripping fault indication state is initiated via a
operator panel pushbutton (labeled SWITCH MODE), dig-
ital SCADA, or discrete SCADA. The UDP feature has
local indication at the operator panel (LED), digital indica-
tion, and remote indication via status contacts on the Dis-
crete Interface (DIF) module 1.
