2.3 CURRENT BEYOND OPERATIONAL LIMITS
If the current is below 10% of nominal rating, the NOVAR 315 will display “_ _ _” ; it will however,
function correctly as a capacitor controller. If the current is higher than 120% of nominal rating “A-HI”
will be displayed and relay switching will stop. Switching will recommence once the current has fallen
below 120% of nominal rating.
3 AUTO MODE
The NOVAR 315 will be in AUTO mode after switching on, otherwise press and hold .
Capacitors will be connected to the system automatically as required to correct the load.
In AUTO mode the NOVAR 315 will display cosϕ, % system voltage, Vn, and % system current, In.
The nominal Vn and In values are printed on the label.
The power factor is displayed as a number when lagging. An additional c denotes a leading power
factor.
If the input lagging vars exceed the c/k setting, IND will be displayed to the right of the AUTO and
capacitors will be connected. If the input leading vars exceed the c/k setting, CAP will be displayed to
the left of the AUTO and capacitors will be disconnected.
Rotate through the displays by repeatedly pressing .
