EXAMPLE 2:
•
Compensated Voltage = 115.0
•
Rev. Set Voltage = 110.0 V
•
Rev. Bandwidth = 4.0 V
•
Control experiencing: Reverse Power Flow
EXAMPLE 3:
•
Compensated Voltage = 123.0 V
•
Cogeneration Mode
•
Fwd. Set Voltage = 120.0 V
•
Fwd. Bandwidth = 2.0 V
•
Control experiencing: Reverse Power Flow
Note: When operating in the Cogeneration Mode,
metering always operates in the forward direction
except that load center voltage is calculated based
upon the line-drop compensation settings when the
fixed 1% reverse metering threshold is exceeded.
Load voltage
When the *Load Voltage key is pressed, the LCD will
display the following information:
The first line displays a live representation of the load voltage.
The load voltage is available at FC 6.
The second line displays the voltage limits to be applied by
the Voltage-Limiting feature (see FC 80). If a voltage range
is displayed, a high and low limit is enabled. A single value
implies that only the high limit is active.
The Voltage Limiter High and Voltage Limiter Low LEDs are
used to indicate the voltage limiter is active.
EXAMPLE 1:
•
Load Voltage = 115.0 V
•
Voltage-Limiting Mode = High and Low Limits Active
•
High Voltage Limit = 121.0 V
•
Low Voltage Limit = 119.0 V
EXAMPLE 2:
•
Load Voltage = 115.0 V
•
Voltage-Limiting Mode = Only High Limit Active
•
High Voltage Limit = 121.0 V
EXAMPLE 3:
•
Load Voltage = 115.0 V
•
Voltage-Limiting Mode = Off
Load current
When the *Load Current key is pressed, the LCD will
display the following information:
The first line displays a live representation of the load
current. The load current is available at FC 9. This line also
includes an abbreviation of the power flow direction: "Fwd"
corresponds to Forward, "Rev" corresponds to Reverse.
The second line displays the current threshold point at
which the control switches operation, either from forward-
to-reverse or reverse-to-forward. The current threshold is the
product of the CT Primary Rating, and the Reverse
Threshold percentage.
EXAMPLE: A 328 A regulator utilizing a CT with a 400 A
primary rating and a 3% reverse threshold value would yield
a 12 A current threshold.
The third line displays the operating mode: Locked Forward,
Locked Reverse, Reverse Idle, Bi-directional, Neutral Idle,
Cogeneration, or Reactive Bi-directional
If automatic operation is blocked, the fourth line displays the
blocking condition. If multiple blocking conditions exist, the
blocking condition with the highest precedence will be
displayed. Refer to Table 7-1 for the blocking condition
priority levels.
The condition illustrated in Example 1 indicates that
automatic operation is inhibited due to an open condition
that exists between terminals 4 and 5 of terminal block 8.
