There are 8 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 (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 appear
in 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 be
installed 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 accumulated
value 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.
