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
is less than the under-voltage set point.
If the mains voltage is less than this set point,
there is a mains failure.
The mains returns when the mains voltage is
more than this set point.
If this parameter is enabled, the controller
detects a mains failure when the mains voltage
is more than the over-voltage set point.
If the mains voltage is more than this set point,
there is a mains failure.
The mains returns when the mains voltage is
less than this set point.
If the voltage is more than the over-voltage set
point when this timer expires, the action for
over-voltage is activated.
Description
If this parameter is enabled, the controller
detects a mains failure when the mains
