•
POWER FACTOR LEAD 1 / 2 RELAY
: Power factor detection can either be disabled,
used as an alarm or as a process control. Set this setpoint to off if the feature is not
required. Selecting alarm relay will cause the alarm relay to activate and display an
alarm message when the power factor is more leading than the level set. Selecting
AUX1, AUX2 or AUX3 relay will cause the respective auxiliary relay to activate when
the power factor is equal to or more leading than the level set, but no message will be
displayed. This is intended for process control. A minimum of 20V applied must exist
on all voltage inputs before this feature will operate.
•
POWER FACTOR LEAD 1 / 2 PICKUP
: When a leading power factor equals or exceeds
the level set by this setpoint, a power factor lead 1/2 condition will occur.
•
POWER FACTOR LEAD 1 / 2 DROPOUT
: When a leading power factor drops below the
level set by this setpoint, the power factor lead 1/2 condition will drop out.
•
POWER FACTOR LEAD 1 / 2 DELAY
: If the power factor equals or exceeds the
POWER
FACTOR LEAD 1/2 PICKUP
setpoint value and remains this way for the time delay
programmed in this setpoint, a power factor lead 1/2 condition will occur.
If the power factor drops below the
POWER FACTOR LEAD 1/2 DROPOUT
setpoint
value, the power factor lead 1/2 condition will drop out. If the
POWER FACTOR LEAD
1/2 RELAY
setpoint is set to
ALARM
, the alarm relay will deactivate and the
POWER
FACTOR LEAD 1/2 ALARM
message will be cleared. If the
POWER FACTOR LEAD 1/2
RELAY
setpoint is set to AUX1, AUX2, or AUX3, the respective auxiliary relay will
deactivate.
•
POWER FACTOR LAG 1 / 2 RELAY
: Power factor detection can either be disabled, used
as an alarm or as a process control. Set this setpoint to off if the feature is not
required. Selecting alarm relay will cause the alarm relay to activate and display an
alarm message when the power factor is more lagging than the level set. Selecting
AUX1
,
AUX2
, or
AUX3
relay activates the respective auxiliary relay when the power
factor is equal to or more lagging than the level set, but no message will be displayed.
This is intended for process control. A minimum of 20 V applied must exist on all
voltage inputs before this feature will operate.
•
POWER FACTOR LAG 1 / 2 PICKUP
: When a lagging power factor equals or exceeds
the level set by this setpoint, a power factor lag 1/2 condition will occur.
•
POWER FACTOR LAG 1 / 2 DROPOUT
: When a lagging power factor drops below the
level set by this setpoint, the power factor lag 1/2 condition will drop out.
•
POWER FACTOR LAG 1 / 2 DELAY
: If the power factor equals or exceeds the
POWER
FACTOR LAG 1/2 PICKUP
setpoint value and remains this way for the time delay
programmed in this setpoint, a power factor lag 1/2 condition will occur.
If the power factor drops below the
POWER FACTOR LAG 1/2 DROPOUT
setpoint
value, the power factor 1/2 lag condition will drop out. If the
POWER FACTOR LAG 1/
2 RELAY
setpoint is set to
ALARM
, the alarm relay will deactivate and the
POWER
FACTOR LAG 1/2 ALARM
message will be cleared. If the
POWER FACTOR LAG 1/2
RELAY
setpoint is set to AUX1, AUX2. or AUX3, the respective auxiliary relay will
deactivate.
