The warning/alarm information below defines each
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 10 V from terminal 50.
Remove some of the load from terminal 50, as the 10 V
supply is overloaded. Max. 15 mA 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 only appears 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. Broken wiring or faulty
device sending the signal can cause this condition.
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.
