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
). 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
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.
