EXAMPLE 2:
Comp Voltage 115.0
Band 108.0-112.0
Using Func 51-55
Compensated Voltage = 115.0
Rev. Set Voltage = 110.0 V
Rev. Bandwidth = 4.0 V
Control experiencing reverse power flow as indicated by
reference to FC 51-55
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 also available at FC 6.
The second line displays the voltage limits to be applied
by the Voltage-Limiting feature (see Section6: Control
Features: Voltage limiter). 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
Limiter 119.0-121.0
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
Limiter 121.0
Load Voltage = 115.0 V
Voltage-Limiting Mode = Only High Limit Active
High Voltage Limit = 121.0 V
EXAMPLE 3:
Load Voltage 115.0
Limiter Off
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 also 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. This is the
point below which the control enters an indeterminate
current flow state. See Section6: Control Features:
Reverse power operation in this manual for more
information on the current threshold. The current threshold
is the product of the CT Primary Rating, and the Reverse
Threshold percentage.
