4.5 List of Warnings and Alarms

WARNING/ALARM 2, Live zero error
This warning or alarm will only appear if programmed by
Word 2
the user in 6-01 Live Zero Timeout Function. The signal on
Off
one of the analog inputs is less than 50% of the minimum
Hand/Auto
value programmed for that input. This condition can be
0
caused by broken wiring or faulty device sending the
0
signal.
0
Troubleshooting:
Check connections on all the analog input
0
terminals. Control card terminals 53 and 54 for
0
signals, terminal 55 common.
Check that the frequency converter programming
match the analog signal type.
WARNING/ALARM 4, Mains phase loss
A phase is missing on the supply side, or the mains
voltage imbalance is too high. This message also appears
Quick Stop
for a fault in the input rectifier on the frequency converter.
Options are programmed at 14-12 Function at Mains
DC Brake
Imbalance.
Stop
Troubleshooting:
0
Check the supply voltage and supply currents to
the frequency converter.
Request
WARNING/ALARM 7, DC overvoltage
If the intermediate circuit voltage exceeds the limit, the
frequency converter trips after a time.
Jog
Troubleshooting:
Start Extend the ramp time
Activate functions in 2-10 Brake Function
0
WARNING/ALARM 8, DC under voltage
Start Delay
If the intermediate circuit voltage (DC) drops below the
under voltage limit, the frequency converter trips after a
Sleep
fixed time delay. The time delay varies with unit size.
Troubleshooting:
Running
Check that the supply voltage matches the
Bypass
frequency converter voltage.
Fire Mode
Perform Input voltage test
WARNING/ALARM 9, Inverter overloaded
texceed
The frequency converter is about to cut out because of an
overload (too high current for too long). The counter for
0
electronic, thermal inverter protection gives a warning at
0
90% and trips at 100%, while giving an alarm. The
frequency converter cannot be reset until the counter is
0
below 90%.
The fault is that the frequency converter is overloaded by
more than 100% for too long.
