•
PHASE A/B/C/N CURRENT DEMAND RELAY: Phase 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 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.
•

Φ
POSITIVE REAL POWER DEMAND RELAY: Three-phase positive real power 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
activates the alarm relay and displays an alarm message whenever the three-
phase real power demand level is equalled or exceeded. Selecting
AUX1
,
AUX2
or
AUX3
activates the
respective auxiliary relay with no message displayed. This is intended for process control.
•
3
Φ
POSITIVE REAL POWER DEMAND LEVEL: When the three-phase real power demand exceeds this
setpoint, a three-phase positive real power demand alarm or process control indication will occur.
•
3
Φ
POSITIVE REACTIVE POWER DEMAND RELAY: Three-phase positive reactive power demand
detection can either be disabled or used as an alarm or process control. Set to
OFF
if this feature is not
required. Selecting
ALARM
activates the alarm relay and displays an alarm message whenever the three-
phase reactive power demand level is equalled or exceeded. Selecting
AUX1
,
AUX2
, or
AUX3
activates the
respective auxiliary relay with no message displayed. This is intended for process control.
•
3
Φ
POSITIVE REACTIVE POWER DEMAND LEVEL: When the three-phase reactive power demand
equals or exceeds this setpoint, a three-phase positive reactive power demand alarm or process control
indication will occur.
•
3
Φ
NEGATIVE REAL POWER DEMAND RELAY: Three-phase negative real power demand detection
can be disabled or used as an alarm or process control. Set to
OFF
if this feature is not required. Selecting
ALARM
activates the alarm relay and displays an alarm message whenever the level of the negative three-
phase real power demand is equalled or exceeded. Selecting
AUX1
,
AUX2
or
AUX3
activates the respective
auxiliary relay with no message displayed. This is intended for process control.
•
3
Φ
NEGATIVE REAL POWER DEMAND LEVEL: When the three-phase real power demand is negative
and exceeds this setpoint, a three-phase negative real power demand alarm or process control indication
will occur.
•
3
Φ
NEGATIVE REACTIVE POWER DEMAND RELAY: Three-phase negative reactive power demand
detection can be disabled or used as an alarm or process control. Set to
OFF
if this feature is not required.
Selecting
ALARM
activates the alarm relay and displays an alarm message if the level of the negative three-
phase reactive power demand is equalled or exceeded. Selecting
AUX1
,
AUX2
or
AUX3
activates the respec-
tive auxiliary relay with no message displayed (intended for process control).
•
3
Φ
NEGATIVE REACTIVE POWER DEMAND LEVEL: If the three-phase reactive power demand is nega-
tive and equals or exceeds this setpoint, a three-phase negative reactive power demand alarm or process
control indication will occur.
•
3
Φ
APPARENT POWER DEMAND RELAY: Three-phase apparent power demand detection can be dis-
abled or used as an alarm or process control. Set to
OFF
if this feature is not required. Selecting
ALARM
acti-
vates the alarm relay and displays an alarm message if the three-phase apparent power demand level is
equalled or exceeded. Selecting
AUX1
,
AUX2
or
AUX3
activates the respective auxiliary relay with no mes-
sage displayed. This is intended for process control.
•
3
Φ
APPARENT POWER DEMAND LEVEL: When the three-phase apparent power demand equals or
exceeds this setpoint, a three-phase apparent power alarm or process control indication will occur.
