CHAPTER 5: SETTINGS GROUPED ELEMENTS
— The coordination timer allows the overcurrent detector to be set below the expected load current
AR CO-ORD BYPASS
seen after reclose. When this setting is enabled (the default value), the coordination timer is bypassed. Disable this setting
(removing the bypass and inserting the timer) if high speed autoreclosure is employed.
— If the setting of the overcurrent detector is less than the load current, then it picks up during a
AR CO-ORD PICKUP DELAY
normal re-energization of the line. This setting delays the assertion of the operand, allowing the recovery of
LINE PICKUP OP
the line voltage to block the scheme.
— This setting extends the assertion of the line pickup output when autoreclose coordination is not
AR CO-ORD RESET DELAY
bypassed.
— This setting allows the line pickup element to be armed from a status signal (such as breaker position)
TERMINAL OPEN
rather than from current and voltage. The FlexLogic operand assigned to this setting indicates that the terminal is opened.
It can be derived by combining the status of several devices in a FlexLogic equation.
— This setting provides zone 1 extension functionality if external autoreclosure is employed.
AR ACCELERATE
— Assertion of the FlexLogic operand assigned to this setting blocks operation of the line pickup
LINE PICKUP BLOCK
element.
— This setting enables and disables the logging of line pickup events in the sequence of events

recorder.
