4 PROGRAMMING
• 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.
This setpoint also applies to the POWER FACTOR DROPOUT 1/2 setpoint. If the power factor drops below the
POWER FACTOR LEAD 1/2 DROPOUT setpoint value and remains this way for the time delay programmed in
this setpoint, 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 pro-
cess 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.
This setpoint also applies to the POWER FACTOR LAG 1/2 DROPOUT setpoint. If the power factor drops below
the POWER FACTOR LAG 1/2 DROPOUT setpoint value and remains this way for the time delay programmed in
this setpoint, 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.
