Warnings
A warning will flash in line 2, while an explanation is
given in line 1.
SETUP

WARNING 1
Under 10 V (10 VOLT LOW)
The 10 V voltage from terminal 50 on the control card
is below 10 V.
Remove some of the load from terminal 50, as the 10
Volts supply is overloaded. Max. 17 mA/min. 590
Ω
.
WARNING/ALARM 2
Live zero fault (LIVE ZERO ERROR)
The current or voltage signal on terminal 53, 54 or 60
is below 50% of the value preset in parameter 309,
312 and 315
Terminal, min. scaling.
WARNING/ALARM 4
Phase fault (MAINS PHASE LOSS)
Phase missing on the supply side.
Check the supply voltage to the VLT frequency
converter.

Alarms
If an alarm is given, the present alarm number will be
shown in line 2. Lines 3 and 4 of the display will offer
an explanation.
WARNING 5
Voltage warning high
(DC LINK VOLTAGE HIGH)
The intermediate circuit voltage (DC) is higher than
Voltage warning high
, see table below. The controls of
the VLT frequency converter are still enabled.
WARNING 6
Voltage warning low (DC LINK VOLTAGE LOW)
The intermediate circuit voltage (DC) is lower than
Voltage warning low
, see table below. The controls of
the VLT frequency converter are still enabled.
WARNING/ALARM 7
Overvoltage (DC LINK OVERVOLT)
If the intermediate circuit voltage (DC) is higher than
the
Overvoltage limit
of the inverter (see table below),
the VLT frequency converter will trip after a fixed
period. The length of this period depends on the unit.
