The four LED indicators on the Option
Board provide information on the
Option Board mode and status and the
network status.
When an error occurs, the Option
Board indicator pattern provides trou-
bleshooting information. For certain
errors, additional information can be
obtained from the trip error code given
by the four-digit display of the Inverter.
In the following sections typical LED
indicator and four-digit Inverter display
patterns are provided to assist in trou-
bleshooting. To show the status of the

When an error occurs, the Option Board trips the Inverter.
For the MX2 Inverter, an error code is displayed on the Digital Operator Dis-
play.
For the RX Inverter, you need to connect the Digital Operator Display to the
Inverter with an Ethernet cable. Then you can see the error code on the dis-
play. Note: if despite the problem it is still possible to communicate with the
unit, the latest error code can also be read in parameter d081.
Use the error code to help troubleshoot the error.
