CHAPTER 4: PROGRAMMING
Selecting auxiliary relay will cause the auxiliary relay to activate for a set level of
positive real power but no message will be displayed. This is intended for process
control.
•
POSITIVE REAL POWER LEVEL:
When the three phase real power equals or exceeds
the level set by this setpoint, an excess positive real power condition will occur.
•
POSITIVE REAL POWER DELAY:
If the positive real power equals or exceeds the
POSITIVE REAL POWER LEVEL
setpoint value for the time delay programmed in this
setpoint, an excessive positive real power condition will occur.
•
NEGATIVE REAL POWER RELAY:
Negative real power level 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 whenever a negative real power level exceeds the selected level.
Selecting auxiliary relay will cause the auxiliary relay to activate for a set level of
negative real power but no message will be displayed. This is intended for process
control.
•
NEGATIVE REAL POWER LEVEL:
When the three phase real power equals or exceeds
the level set by this setpoint, an excess negative real power condition will occur.
•
NEGATIVE REAL POWER DELAY:
If the negative real power equals or exceeds the
NEGATIVE REAL POWER LEVEL
setpoint value for the time delay programmed in this
setpoint, an excessive negative real power condition will occur.
•
POSITIVE REACTIVE POWER RELAY:
Positive reactive power level 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 whenever a positive reactive power level exceeds the
selected level. Selecting auxiliary relay will cause the auxiliary relay to activate for a
set level of positive reactive power but no message will be displayed. This is intended
for process control.
•
POSITIVE REACTIVE POWER LEVEL:
When the three phase reactive power equals or
exceeds the level set by this setpoint, an excess positive reactive power condition will
occur.
•
POSITIVE REACTIVE POWER DELAY:
If the positive reactive power equals or exceeds
the
POSITIVE REACTIVE POWER LEVEL
setpoint value for the time delay
programmed in this setpoint, an excessive positive reactive power condition will occur.
•
NEGATIVE REACTIVE POWER RELAY:
Negative reactive power level 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 whenever a negative reactive power level exceeds the
selected level. Selecting auxiliary relay will cause the auxiliary relay to activate for a
set level of negative reactive power but no message will be displayed. This is intended
for process control.
•
NEGATIVE REACTIVE POWER LEVEL:
When the three phase reactive power equals or
exceeds the level set by this setpoint, an excess negative reactive power condition will
occur.
•
NEGATIVE REACTIVE POWER DELAY:
If the negative reactive power equals or exceeds
the
NEGATIVE REACTIVE POWER LEVEL
setpoint value for the time delay
