•
PHASE A/B/C/N CURRENT DEMAND RELAY
: Phase/neutral current demand detection
can either be disabled or used as an alarm or process control. Set this setpoint to
OFF
if the feature is not required. Selecting alarm relay activates the alarm relay and
displays an alarm message whenever a phase/neutral current demand level is
equalled or exceeded. Selecting AUX1, AUX2 or AUX3 relay activates the respective
auxiliary relay with no message displayed. This is intended for process control.
•
PHASE A/B/C/N CURRENT DEMAND LEVEL
: When the phase A/B/C/N current demand
equals or exceeds this setpoint, a phase A/B/C/N demand alarm or process control
indication occurs.
