Open BypassA 11 NNN

F Open Bypass Phase A Device senses that the bypass contactor
did not close on the respective phase.

F Open Bypass Phase C
No Load 14 N Y Y F/A The SMC-50 control module can determine if a load connection
exists (total load lost or all load leads lost) and a No Load Fault and/or
Alarm can be indicated.
Open Load A 15 N Y Y F/A An Open Load A Fault/Alarm indicates that the Phase X
load lead connection is OFF/Open.
B16 F/A An Open Load B
C17 F/A An Open Load C
Voltage
Unbalance
18 YYYF/A Indicates that when the calculated unbalance level is greater than
the user-defined Fault and/or Alarm level. See Chapter 4 for calculated
value details.
Overvoltage 19 YYYF/A Indicates that if the average line voltage is greater than the user-
defined Fault and/or Alarm level.
Undervoltage 20 Y Y Y F/A Indicates that if the average line voltage is less than the user-
defined Fault and/or Alarm level.
Overload 21 Y
(1)
YYF/A Enabled in the Motor Protection Group by programming the:
Overload Class, Overload Reset, Motor FLC, and Service Factor.
Underload 22 YYYF/A Motor operation will halt (Fault only) if the value of the motor’s
average RMS current is less than the user-defined value.
Jam 23 YYYF/A Indicates that the motor current increases above the user-defined
Fault and or Alarm level while the motor is running at speed. This F/A
condition is not active during starting or stopping.
Stall 24 YYYF/A Condition exists and a Fault/Alarm is generated if the SMC-50
control module senses that the motor is NOT Up-to-Speed (UTS) at the
end of the programmed starting ramp time plus the time programmed
in the Stall Delay time.
Phase Reversal 25 N Y Y F/A Fault/Alarm is indicated when the incoming power to the SMC-50
control module is in any sequence other than ABC.
Exp Removed 26 NNN
A
F Removing an expansion module (device) (for example, a 150-SM4)
from a SMC-50 control module will result in a x026 fault, where "x" is
the SMC-50 control module port number (7, 8, or 9) the expansion
module was installed. DPI devices (for example, 20-HIM-A6 or 20-
COMM-X) will only generate this fault if its associated bit in Logix Mask
parameter is set.
NOTE: If an expansion module (device) (for example, a 150-SM4 is
removed from a SMC-50 controller), the message "Device Conflicts Port
xy Not Found" is displayed on the HIM or PC software) when power
returns.
Exp Incompat 27 NNN
A
F Inserting an expansion module or DPI device into an incompatible
control module port number or inserting an expansion module into a
control module with incompatible version of firmware results in this
Fault. The port number of the offending device is included as the first
digit of this Fault code.
Expansion 28 NNN
A
F General Fault that can be generated by an expansion or peripheral
device. The port number of the offending device is included as the first
digit of this Fault code.
