ACH580 E-Clipse Bypass
3006 UNDERVOLTAGE 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 99 for the J7
connector location)
Loose input wiring
Incoming power
problems
Check that J7 connector
is firmly seated in RBCU
(refer to page 99 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 connections on
drive
Check connections on

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 ACH580
manual for proper
troubleshooting
techniques
Bypass Mode:
Check that J2 connector
is firmly seated in RBCU
(refer to page 99 for the
J7 connector location)
Use clam
p 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 99 for the
J7 connector location)
Loose wiring on
Contactor assembly.
Blown upstream fuse
Check J7 connector
(refer to page 99 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 99 for the
J7 connector location)
Loose wiring on
Contactor assembly.
Blown upstream fuse
Check J7 connector
(refer to page 99
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 99 for the
J7 connector location)
Loose wiring on
Contactor assembly.
Blown upstream fuse
Check J7 connector
(refer to page 99 for the
