INPUT PHASE LOSS
(programmable
fault function,
parameter 3016
SUPPLY PHASE)
Intermediate circuit DC voltage is
oscillating due to missing input
power line phase or blown fuse.
Alarm is generated when DC
voltage ripple exceeds 14% of
nominal DC voltage.
Check input power line fuses.
Check for input power supply imbalance.
Check fault function parameter setting.
1)
Even when the relay output is configured to indicate alarm conditions (for example, parameter 1401
RELAY OUTPUT 1 = 5 [ALARM] or 16 [FLT/ALARM]), this alarm is not indicated by a relay outpu t.
