4 Device status and fault detection
4.1 Device status
Various diagnostic functions enable EMS electronic motor starters to detect
a large number of internal and external faults (peripheral faults)
When a fault is detected, the device will be in a safe, disconnected state.
Internal faults cannot be acknowledged and will be stored in the device.
If more than 14 internal faults occur, it will no longer be possible to operate
the device.
In the case of external faults, you will have to acknowledge the error in order
to leave the safe disconnected state.
Table 7 below shows the various LED state combinations, the device
statuses to which they correspond, and the corresponding error acknowledg-
ment details.
