Diagnostics
3006 UNDERVOLT
AGE
Fault will be generated
only if the drive is
controlling the motor
and the power to the
bypass is removed
before the drive shuts
down. This fault is
generated when the
drive contactor opens
while the drive is
operating.
Loose J7 connector
on RBCU unit (refer
to page 17 for the J7
connector location)
Loose input wiring
Incoming power
problems
Check that J7 connector is
firmly seated in RBCU (refer
to page 17 for the J7
connector location)
Check tightness of incoming
connections
Check Parameter 0413 to
view voltage level at time of
trip
Check upstream protection
3008 DRIVE AI2
LOSS
Only displayed when in
Supervisory mode.
Indicates that AI2 on the
drive has failed.
Check ACH580
manual for AI2 loss
Check ACH580 manual for
AI2 loss
3009 MTR
OVERLOAD
Bypass opens on motor
overload conditions
defined in the drive
Drive Mode:
Bad Motor
Bad CTs
Bad RBCU
Bypass mode:
Bad motor
Bad CTs
Bad RBCU
Either mode:
low input voltage
Check if overload condition
exists
Drive Mode:
Refer to 580 manual for
proper troubleshooting
techniques
Bypass Mode:
Check that J2 connector is
firmly seated in RBCU
Use clamp meter to verify mtr
current vs. display in
parameter 0101
Check input voltage
3010 INP PHASE A
LOSS
Fault will be generated
when the bypass
contactor is requested to
be closed and the RBCU
does not sense voltage
on Phase A
Loose J7 connector
(refer to page 17 for
the J7 connector
location)
Loose wiring on
Contactor assembly.
Blown upstream fuse
Check J7 connector (refer to
page 17 for the J7 connector
location)
Check yellow wire on input
block
Check incoming voltage,
phase to ground
3011 INP PHASE B
LOSS
Fault will be generated
when the bypass
contactor is requested to
be closed and the RBCU
does not sense voltage
on Phase B
Loose J7 connector
(refer to page 17 for
the J7 connector
location)
Loose wiring on
Contactor assembly.
Blown upstream fuse
Check J7 connector (refer to
page 17 for the J7 connector
location)
Check black wire on input
block
Check incoming voltage,
phase to ground
3012 INP PHASE C
LOSS
Fault will be generated
when the bypass
contactor is requested to
be closed and the RBCU
does not sense voltage
on Phase C
Loose J7 connector
(refer to page 17 for
the J7 connector
location)
Loose wiring on
Contactor assembly.
Blown upstream fuse
Check J7 connector (refer to
page 17 for the J7 connector
location)
Check red on input block
Check incoming voltage,
phase to ground
3013 DRIVE 1ST
START
Fault generated if
attempting to close the
bypass contactor with
out running the bypass
in drive mode first.
