Relay Control Logic Section
The ‘Relay Control Logic’ section is used to set the trigger thresholds for the selected source data
register.
Run System (Energize Relay)
– Select the logic operand to use for the “energize” logic evaluation.
Value
– The value that the relay will be energized. Note that the energized state is the normal “operating”
state of the relay.
Shutdown System (De-Energize Relay)
– The logic operand to use for the “de-energize” logic evaluation.
This will automatically be the opposite of the selection for the energize case. Note that the de-energized state
is the SAFE state of the relay.
Value
– The value that the relay will be de-energized. Note that the de-energize state is the “safe” state of the
relay.
Number of Readings
– This field contains the number of check-in packets that must be received in a row that
are above (or below) the logic threshold for the de-energize condition. This is useful so that a single (possibly a
glitch) reading does not cause a shut-down. The default is 1 where each check-in will cause the rule to be
evaluated and acted on. A single reading that satisfies the run system (energize) condition will cause the relay
to energize.
