Connection between the
control unit and the power

Measurement circuit fault.
Version check cannot find a
matching power unit FPGA
logic, or number of
connected power modules
differs from specified.

What to do
Check setting of 195.04 Control board
supply.
Check the connection between the
control unit and the power unit.
Check the auxiliary code (format XXXY
YYZZ). With parallel-connected
modules, "Y YY" specifies the affected
control unit channel (0: broadcast).
"ZZ" specifies the error source (1:
Transmitter side [link error], 2:
Transmitter side [no communication],
3: Receiver side [link error], 4: Receiver
side [no communication], 5:
Transmitter FIFO error [see "XXX"], 6:
Module [xINT board] not found, 7:
BAMU board not found). "XXX"
specifies the transmitter FIFO error
code (1: Internal error [invalid call
parameter], 2: Internal error
[configuration not supported],
3: Transmission buffer full).
Check the connection between the
control unit and the power unit.
Contact your local ABB representative.
Contact your local ABB representative,
quoting the auxiliary code.
Check the auxiliary code (format ZZZY
YYXX). "YY Y" specifies the affected
module (0...C). "XX" specifies the
affected power supply (1: Power
supply 1, 2: Power supply 2, 3: both
supplies).
Contact your local ABB representative,
quoting the auxiliary code.
If the number of connected power
modules is correct (parameter
Parallel connection rating
the FPGA logic of the power unit.
Cycle the power to the supply unit. If
the control unit is externally powered,
also reboot the control unit (using
parameter 196.08 Control board
or by cycling its power.
If the problem persists, contact your
local ABB representative.
