Fault Messages Chapter 1
X Adaptr1 ForceFlt 26 There has been a loss of communication between the
identified DPI adapter and the customer’s communication
network. The communication between the drive and the DPI
adapter may still be active. This is a requirement for DPI
communications. If the loss of communication from the
network to the adapter is required to be a warning, this must
be set in the adapter itself, not within the drive.
• Verify the customer network is properly communicating with the device.
• Check DPM status LEDs and compare to the information in the User Manual.
• Change the adapter if all attempts to restore communication fail.
• Cycle control power.
X Adaptr2 ForceFlt 27
X Adaptr3 ForceFlt 28
X Adaptr4 ForceFlt 29
X Adaptr5 ForceFlt 30
X Adaptr6 ForceFlt 31
Ambient OvrTemp 182 NOT ACTIVE
Ambient LowTemp 183 NOT ACTIVE
Ambient FbrOptic 184 NOT ACTIVE
Ambient Sensor 185 NOT ACTIVE
X Arbitration Loss 602 The number of Arbitration Loss faults has exceeded the
maximum allowable level.
• Check the DCSL communication wiring and shielding.
X Auxiliary Prot’n 37 Standard External Fault/Warning Input included to allow the
end user to install a protective relay/system status contact
that can activate a drive fault or warning, depending on
configuration of Aux Prot Class (P445). The message means
that the drive has detected a fault triggered by the input
wired in the auxiliary input of the XIO card.
• Check the device responsible for the auxiliary contact to this input, and investigate the
cause of the open contact status.
• Check the 120V signal through the external device.
• Check the XIO board inputs and parameter status bits.
• Check the 120V wiring and the XIO card.
X Bypass CtctrOpen 168 The bypass contactor was opened without a command from
the drive. Verify the contactor feedback and the 120V wiring
to the ACB.
• Because the drive system needs to have complete control over all contactors, investigation
of the specific contactor fault is required.
• Verify contactor feedback.
• Verify the control power circuit for the contactor.
• Check permissive string to the contactor control relay (refer to drawing).
• Check contactor/breaker for physical malfunction (auxiliaries).
• Check ACB inputs and outputs at J1.
X Bypass IsoSwClsd 175 The bypass isolation switch is closed when it was expected to
be open. Verify the isolation switch mechanical set up and the
120V wiring to the ACB. Depending on the operating mode of
the drive, ensure that the switch is in the proper position.
• Depending on the mode of operation (Normal, System Test, Open-Circuit Test, DC Current
Test, or Open-Loop), there are specific states for all the possible system isolation switches
(Refer to the description of parameter 141 Hardware Options1. Be sure the isolation switches
are in the proper position.
• Verify wiring feedback.
• Verify isolation switch mechanical auxiliary setup.
• READ ASSOCIATED DESCRIPTION.
X Bypass IsoSwOpen 172 The bypass isolation switch is open when it was expected to
be closed. Verify the isolation switch mechanical set up and
the 120V wiring to the ACB. Depending on the operating
mode of the drive, ensure that the switch is in the proper
position.
