• DETECT I/V ALARMS USING PERCENTAGE: When "Yes" is selected, all current and
voltage alarms can be set in percentages of CT and VT. When "No" is selected, all
current and voltage alarms are actual voltage and current levels.
• PHASE UNDERCURRENT RELAY: Undercurrent can be disabled, used as an alarm, or
as a process control feature. Set this setpoint to "Off" if the feature is not required.
Selecting "Alarm" activates the alarm relay and displays an alarm message whenever
an undercurrent condition exists. Selecting an auxiliary relay activates the selected
auxiliary relay for an undercurrent condition but no message will be displayed. This is
intended for process control.
• PHASE UNDERCURRENT LEVEL: When the average three phase current drops to or
below the level set by this setpoint, a phase undercurrent condition will occur. Refer to
the
DETECT UNDERCURRENT WHEN 0A
undercurrent detection below 5% of CT.
• PHASE UNDERCURRENT DELAY: If the average phase current is less than or equal to
the
PHASE UNDERCURRENT LEVEL
setpoint, a phase undercurrent condition will occur.
