186 Fault tracing
Code Fault
(hex)
5E05 Rating ID mismatch
5E07 PU communication
5E08 Power unit lost
5E09 PU communication
internal
Cause
The hardware of the DC/DC
converter unit does not match
the information stored in the
memory unit. This may occur
eg, after a firmware update or
memory unit replacement.
The way the control unit is
powered does not correspond
to parameter setting.
Communication errors
detected between the control
unit and the power unit.
Connection between the
control unit and the power unit
is lost.
Internal communication error.
What to do
Cycle the power to the DC/DC converter.
If the control unit is externally powered,
reboot the control unit (using parameter
196.08 Control board boot) or by cycling
its power.
Check the auxiliary code. The auxiliary
codes are as follows:
1 = Ratings pf the power unit and BCU
control unit are not the same. Rating ID
has changed.
2 = Parallel connection rating ID has
changed.
3 = Power unit types are not the same in
all power units.
4 = Parallel connection rating ID is active
in a single power unit setup.
5 = It is not possible to implement the
selected rating with the current power
units.
6 = Power unit rating ID is 0.
7 = Reading power unit rating ID or
power unit type failed on connection.
With parallel connection faults, the format
of the auxiliary code is 0X0Y. "Y"
indicates the auxiliary code, "X" indicates
the first faulty power unit channel in
hexadecimal (1...A).
If the problem persists, contact your local
ABB representative.
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 BCU 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.
