System Settings
Within System Settings, you can change parameters for the
system. When the unit is part of a parallel system, all of
these settings for each unit must match.

System Settings screen (EV12 type)
Press Login to display the Login screen.
Press Restore if you want to reset parameters to the
default values.
Press the screen name to access a screen.
Compensation Mode Screen (HCU2 type)
Harmonic Modee:
Activates/Deactivates the harmonic
correction mode.
PF Modee:
Activates/Deactivates the Power Factor
correction mode.
Optimized PFe:
When set to OFF, the unit maintains the
PF cos (phi) setting. When set to ON and the load is less
than the PF cos(phi) setting, the unit corrects the power
factor to PF cos (phi). If the load PF is greater than the
setting, the unit does not compensate unless the power
factor is set to maintain a Lag power factor and the load
becomes leading. Then, the unit corrects the power factor
to a PF cos (phi) of 1.00. If the PF cos (phi) is set to Lead
and the power factor of the load is lagging, the unit corrects
to a PF cos (phi) of 1.00.
Example:
With a PF cos (phi) set to 0.98 Lag, the unit
maintains a Power Factor of 0.98 Lag when the corrected
load is lagging. If the power factor improves to 0.99, no
compensation is provided. If the connected load produces
a leading power factor, the unit corrects the power factor
to 1.00.
PF cos (phi)e:
Target power factor setting.
Load Balancinge:
Activates/deactivates load balancing mode.
Harmonic Prioritye:
Sets the percentage of the unit’s output
to harmonic mitigation when the system is at or over
maximum capacity.
Funde:
Displays the percentage of the unit’s rating that is
dedicated to correcting fundamental current as the result
of the Harmonic Priority setting. This is mathematically
calculated based on the Harmonic Priority setting.
Harmonic Priority only affects the unit when harmonic mode
and at least one other mode of operation is enabled. When
the total current output of the active filter required exceeds
the unit’s rating, harmonic priority determines which mode
has priority. With harmonic priority set to 100%, the unit
outputs all current necessary to correct the harmonic
content. Any output capacity left over is used for correcting
PF and/or load balancing. Conversely, with harmonic
priority set to 0%, the unit outputs the fundamental current
required for correcting power factor and/or load balancing.
