Band Status
Indicates one of three conditions: High, when voltage is out of band high, Low when
voltage is out of band low, or OK when voltage is within band.
VAr Bias Effect
Indicates one of three conditions when enabled. If the control has determined that the
absolute reactive power is >¾ of the Max Cap Bank Setting and the inverse timer has
timed out, then the control will increase the effective bandcenter by 1 Volt depending on
the direction of the reactive power and will either indicate "Bandcenter Raise" for negative
reactive power or "Bandcenter Lower" for positive reactive power. If the absolute power
is <¾ of the Max Cap Bank Setting then the display will indicate "None".
Power Direction
Indicates one of two power directions: Forward (forward power condition) or Reverse
(reverse power condition).
Voltage Reduction
VR Off indicates voltage reduction is not active, blocked either by non-sequential input,
reverse power condition, or by communicated command. VR Step 1, 2, and 3 indicate that
voltage reduction is in effect for the stated step value. VR Step 1, 2, and 3 indicate that
voltage reduction has been implemented from the control front panel for the stated step
value.
HMI Active Mode
Indicates that HMI menu at the control is active. Turns off after 15 minutes of inactivity.
3.6.7 Aux input status
Indicates (red) when the Auxiliary Input is active.
