A digital counter counts the number of state transitions fromLogic 0 to Logic 1. The counter is used to count operations such as the pickups of an element, the changes of state of anexternal contact (e.g. breaker auxiliary switch), or pulses from a watt-hour meter.COUNTER 1 UNITS:Assigns a label to identify the unit of measure pertaining to the digital transitions to be counted. The units label will appearin the corresponding Actual Values status.COUNTER 1 PRESET:Sets the count to a required preset value before counting operations begin, as in the case where a substitute relay is to beinstalled in place of an in-service relay, or while the counter is running.COUNTER 1 COMPARE:Sets the value to which the accumulated count value is compared. Three FlexLogic™ output operands are provided to indi-cate if the present value is "more than (HI)", "equal to (EQL)", or "less than (LO)" the set value.COUNTER 1 UP:Selects the FlexLogic™ operand for incrementing the counter. If an enabled UP input is received when the accumulatedvalue is at the limit of +2,147,483,647 counts, the counter will rollover to –2,147,483,647.COUNTER 1 DOWN:Selects the FlexLogic™ operand for decrementing the counter. If an enabled DOWN input is received when the accumu-lated value is at the limit of -2,147,483,647 counts, the counter will rollover to +2,147,483,647.
