INTERBUS operation.
off or
green
Standard operation (see table for TR = green)
-
flashing
yellow
Inverter is in initialization phase
-
steady red
Incorrect DIP switch configuration selected,
no INTERBUS operation possible.
Check the settings of DIP switch S1. Correct
the settings of the DIP switches and turn the
unit on again.

Incorrect DIP switch configuration or defec-
tive INTERBUS option card, no INTERBUS
operation possible.
Check the setting of DIP switch S1. If the set-

Status
Meaning
OFF
Standard operating status. The UFI11A is exchanging data with the connected inver-
ters.
FLASHES 1 x
briefly with long
pause
Autosetup has been selected using the DIP switch and the UFI11A is currently set-
ting up its configuration. If this status lasts for more than one minute, turn off the
Autosetup mode and turn it on again. Replace the module if the behavior persists.
FLASHES regularly
UFI11A is in error status. If you started the UFI11A using the Autosetup DIP switch,
turn the UFI11A off and on again. If the LED is still on, restart Autosetup by turning
the DIP switch off and on again. If you started the UFI11A with MOVITOOLS, you
will see an error message in the status window. Consult the corresponding error
description.
ON
The UFI11A is not exchanging data with the connected inverters. Either is has not
been configured or one or more of the connected inverters are not responding.
Reconfigure the UFI11A. If you started up the UFI11A using Autosetup, please
switch the Autosetup DIPswitch off and on again. If the LED stays on after Autose-
tup, please check the cabling and the terminating resistors of the SBus as well as
the inverter voltage supply. If you started up the UFI11A using MOVITOOLS, click
the "Update" button in the Movitools Manager. All the inverters should be displayed
in the "Connected Inverters" window. If this is not the case, please check the cabling
and the terminating resistors of the SBus as well as the inverter voltage supply.
Reconfigure the UFI11A with MOVITOOLS if necessary.
