Operating principle
The LED error display provides information on the cause of the error. After notification by the
flash signal, the error type is displayed followed by the error location/error code.
The LED error display
● takes precedence over all other states that are displayed by the ERROR and MAINT LEDs.
● remains switched on until the cause of the error is eliminated
Table 6-7 Display of error type and error location
Sequence
1 ER and MT LEDs flash 3x at 0.5 Hz
2 MT LED flashes at 1 Hz
3 ER and MT LEDs flash 3x at 2 Hz
4 ER LED flashes at 1 Hz
5 MT LED flashes at 1 Hz
6 Repeat steps 1 to 5 until the cause of the error has been eliminated.
