Description
When the delay timer expires, the action for
unbalanced load is activated if the load is more
than the unbalanced set point.
If this parameter is enabled, the configured
action for low load is activated.
The action that occurs when low load is
detected. Low load is detected when the load is
less than the set point for low load trip (LOW
LOAD TRIP).
The set point for low load. When the load is less
than this set point, the action for low load is
activated.
If the action for low load is a warning, the
controller stops monitoring low load when the
load is more than this set point.
If the load is less than the set point for low load
when the time expires, the low load action is
activated.
Description
If this parameter is enabled, the controller
monitors the mains voltage and frequency.
Select the phase system for the mains.
If this parameter is enabled, a phase reversal is
detected if the phase sequence is not L1-L2-L3.
Configure the action for phase reversal
detection.
If this parameter is enabled, a mains failure is
not detected if one or two of the phases fail.
This is only for a 3-phase system.
Enable this parameter, if the application
includes a mains power transformer (PT).
Configure the PT primary value.
Configure the PT secondary value.
Description
If this parameter is enabled, the controller
detects a mains failure when the mains voltage
