8.4.1 Fault Messages
The warning/alarm information below defines the warning/
alarm condition, provides the probable cause for the
condition, and details a remedy or troubleshooting
procedure.
WARNING 1, 10 Volts low
The control card voltage is below 10V from terminal 50.
Remove some of the load from terminal 50, as the 10V
supply is overloaded. Max. 15mA or minimum 590
Ω
.
This condition can be caused by a short in a connected
potentiometer or improper wiring of the potentiometer.
Troubleshooting
Remove the wiring from terminal 50. If the warning clears,
the problem is with the customer wiring. If the warning does
not clear, replace the control card.
WARNING/ALARM 2, Live zero error
This warning or alarm will only appear if programmed by the
user in
6-01 Live Zero Timeout Function
. The signal on one of
the analog inputs is less than 50% of the minimum value
programmed for that input. This condition can be caused by
broken wiring or faulty device sending the signal.
Troubleshooting
Check connections on all the analog input
terminals. Control card terminals 53 and 54 for
signals, terminal 55 common. MCB 101 terminals
11 and 12 for signals, terminal 10 common. MCB
109 terminals 1, 3, 5 for signals, terminals 2, 4, 6
common).
Check that the frequency converter programming
and switch settings match the analog signal type.
Perform Input Terminal Signal Test.
WARNING/ALARM 3, No motor
No motor has been connected to the output of the
frequency converter.
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 for a fault
in the input rectifier on the frequency converter. Options are
programmed at
14-12 Function at Mains Imbalance
.
Troubleshooting
Check the supply voltage and supply currents to the
frequency converter.
WARNING 5, DC link voltage high
The intermediate circuit voltage (DC) is higher than the high
voltage warning limit. The limit is dependent on the
frequency converter voltage rating. The frequency converter
is still active.
