Operation
The unit is ready for operation when the Power LED is permanently lit.
LEDs indicate the status and errors during operation:
LED on
LED flashes
Information
Status indicators and error indicators may occur independently. In the case
of an error display, the "Fault" LED will light or flash (exception: "Supply
voltage too low"). An LED that is also flashing indicates the potential cause
of the error. An LED that is lit and is static indicates a normal operating sta-
tus. Several status indicators and error indicators may occur simultaneously.
