CONTROL ELEMENTS
There are eight identical digital counters, numbered from 1 to 8. A digital counter counts the number of state transitions
from Logic 0 to Logic 1. The counter is used to count operations such as the pickups of an element, the changes of state of
an external contact (for example, breaker auxiliary switch), or pulses from a watt-hour meter.
— Assigns a label to identify the unit of measure pertaining to the digital transitions to be counted. The
COUNTER 1 UNITS

units label appears in the corresponding actual values status.
COUNTER 1 PRESET
substitute relay is to be installed in place of an in-service relay, or while the counter is running.
COUNTER 1 COMPARE
operands are provided to indicate if the present value is 'more than (HI)', 'equal to (EQL)', or 'less than (LO)' the set value.
— Selects the FlexLogic operand for incrementing the counter. If an enabled UP input is received when the
COUNTER 1 UP
accumulated value is at the limit of +2,147,483,647 counts, the counter rolls over to –2,147,483,648.
COUNTER 1 DOWN
when the accumulated value is at the limit of –2,147,483,648 counts, the counter rolls over to +2,147,483,647.

captured frozen value with the associated date/time stamp are available as actual values. If control power is interrupted,
the accumulated and frozen values are saved into non-volatile memory during the power-down operation.
