850 FEEDER PROTECTION SYSTEM – INSTRUCTION MANUAL 4–287
1. When the Counter is enabled and Digital Counter 1 Set to Pre-Set operand has value 1
(when the Counter is enabled and Digital Counter 1 Set to Pre-Set operand has value 0,
the Counter will be set to 0).
2. When the Counter is running and Digital Counter 1 Set to Pre-Set operand changes
the state from 0 to 1 (Digital Counter 1 Set to Pre-Set changing from 1 to 0 while the
Counter is running has no effect on the count).
3. When a reset or reset/freeze command is sent to the Counter and Digital Counter 1
Set to Pre-Set operand has the value 1 (when a reset or reset/freeze command is sent
to the Counter and Digital Counter 1 Set to Pre-Set operand has the value 0, the
Counter will be set to 0).
RESET
Range: Off, Any FlexLogic operand
Default: Off
The setpoint selects the FlexLogic operand for setting the count, either 0 or the pre-set
value depending on the state of the Counter 1 Set to Pre-set operand.
FREEZE/RESET
Range: Off, Any FlexLogic operand
Default: Off
The setpoint selects the FlexLogic operand for freezing (capturing) the accumulating
count value into a separate register with the associated date and time of the operation
while resetting the count to either 0 or the pre-set value depending on the state of the
“Counter 1 Set to Pre-set” operand.
FREEZE/COUNT
Range: Off, Any FlexLogic operand
Default: Off
The setpoint selects the FlexLogic operand for freezing (capturing) the accumulating
count value into a separate register with the associated date and time of the operation
while continuing counting. The present accumulated value and frozen (captured) value
with the associated date/time stamp are available as STATUS values. If control power is
interrupted, during the power-down operation, the accumulated and frozen (captured)
values are saved into non-volatile memory.

“Disabled”.
