6 Faults and Warnings
When a problem occurs in the system, the Inverter will inform the user on the Fault Lamp. The Inverter displays
two basic error messages in the CMT (Support the PC and the Mobile version). The fi rst, the fault, is a serious
problem that causes the inverter to stop running. The second, a warning, is a minor problem that does not
cease the system operation. The CMT will indicate faults in red and warnings in yellow. The user can fi nd a
description of the different fault and warnings in the following Tables.
