Power-Reversal Relay Delay
This function sets the delay time before a power
reversal trip occurs. The range of delays is 1 to 1 5
seconds, i n steps o f 1 second. Choosing
O F F
disables
power-reversal protection. The Trip Unit display is

Rating Plug Current Setting
The Trip Unit display for rating plug setting is shown
in Figure 39. Enter the current setting of the rating
plug by scrolling through the list with
VALUE
and
pressing
E N T E R
when the correct value is reached.
Table 1 6 lists the available rating plugs for the vari
ous Trip Units.
CAUI'ION:
Incorrect storage of this set point will
result in incorrect metering values.
AITENTION:
Si une valeur incorrecte est enregistree
pour ce reglage, les mesures seront fausses.

Potential Transformer Primary Voltage
Enter the primary voltage rating of the potential
transformer, as illustrated in Figure 40. The range of
values is 1 20 to 600 volts, with an increment of 1 volt.
CAUI'ION:
Incorrect storage of this set point will
result in incorrect metering values. Even
if
this set
ting is entered remotely, it must be entered again
locally.
AITENTION:
Si une valeur incorrecte est enregistree
pour ce reglage, les mesures seront fausses. Cette
valeur doit etre enregistree locallement meme dans
le cas d'une utilisation
