Alarm Time Delay
This is the amount of time (in seconds) that the neutral-to-ground voltage must exceed
the "Alarm Level" before the control device issues an alarm.
Gross Overvoltage Level
This is the voltage level or tap-point voltage percent imbalance considered a gross
overvoltage.
Gross Overvoltage Time Delay
This is the amount of time (in seconds) that the neutral-to-ground voltage must exceed
the "Gross Overvoltage Level" before the control device locks out the capacitor bank or
reactor.
Unbalance Compensation
This field shows whether unbalance compensation is enabled or disabled. When
enabled, the options are "Cap/Line" (the control device compensates for the system
voltage imbalance plus the inherent capacitor bank imbalances), or "Cap Only" (the
control device compensates for inherent capacitor bank imbalances only).
Auxiliary Contact
This field displays whether the device is configured to accept an "a" or "b" contact from
the capacitor bank or reactor switching device, or is disabled.
Neutral-to-Ground Ratio
This field shows the voltage ratio setting for the neutral-to-ground potential device.
Nominal Operating Frequency
This is the nominal operating frequency (in Hz) for your distribution system.
Alarm State at Power Up
When this field displays "Alarmed," the control device issues an alarm and turns ON the
ALARM INDICATOR LED when power returns after an outage.
The control device optionally provides one or two sets of alarm relays; each set
includes one normally open relay and one normally closed relay. All alarm relays oper-
ate simultaneously.
While the control device is unpowered, the normally closed contacts are closed. When
the "Alarm State at Power Up" setpoint is set to "Unalarmed" and the control device
powers up, the normally closed relay contacts open. When the "Alarm State at Power
Up" setpoint is set to "Alarmed" and the control device powers up, the normally closed
relay contacts remain closed.
Output Contact Pulse Time
This is the amount of time (in seconds) that the control device energizes the capacitor
bank/reactor switching device's open or close circuitry (as appropriate).
Phase/Tap-Point-to-Neutral Ratio
This field shows the voltage ratio setting for the Phase line potential devices.
