SMC Flex Module Parameter Information
Unbalance
Unbalance A Dly
66
Secs
0…99
0
Allows the user the ability to prevent some nuisance
Alarms by entering a delay period that provides a
window that the voltage unbalance condition must
persist within for the controller to Alarm.
Jam
Jam F Lvl
67
%FLC
0…1000
0
Allows the user to set an instantaneous over current
level (% of line FLC) that will cause a fault. A zero
value is the “off” setting.
Jam
Jam F Dly
68
Secs
0…99
0
Allows the user the ability to prevent some nuisance
faults by entering a delay period that provides a
window that the motor over current condition must
persist within for the controller to fault.
Jam Jam
A
Lvl 69 %FLC
0…1000
0
Allows the user to set an instantaneous over current
level (% of line FLC) that will cause an Alarm. A zero
value is the “off” setting.
Jam Jam
A
Dly 70 Secs
0…99 0
Allows the user the ability to prevent some nuisance
Alarms by entering a delay period that provides a
window that the motor over current condition must
persist within for the controller to Alarm.
Stall Stall
Delay 71 Secs
0.0…10.0
0
This feature allows the user to program the amount
of time beyond the initial start maneuver for the
motor to be at speed. A setting of zero means that
the stall detection feature is disabled.

Ground Fault Gnd Flt Enable
72
Disable
Enable
Disable
Enables ground fault protection when used with an
external core balanced ground fault sensor.
Ground Fault Gnd Flt Level
73
A
1.0…5.0
2.5
Allows the user to set a current (core balance
current) that will cause a fault when the current is
above this value.
Ground Fault Gnd Flt Delay
74
Secs
0.1…250.0
0.5
Allows the user the ability to prevent some nuisance
faults by entering a delay period that provides a
window that the ground fault condition must
persist within for the controller to fault.
Ground Fault Gnd Flt Inh Time
75
Secs
0…250
10
Allow the user the ability to disable/inhibit ground
fault protection for a selected time when starting.
Ground Fault Gnd Flt A Enable
76
Disable
Enable
Disable
Enables a ground fault protection Alarm when used
with an external core balanced ground fault sensor.
Ground Fault Gnd Flt A Lvl
77
A
1.0…5.0
2.0
Allows the user to set a current (core balance
current) that will cause an Alarm when the current
is above this value.
Ground Fault Gnd Flt A Dly
78
Secs
0…250
10
Allows the user the ability to prevent some nuisance
Alarms by entering a delay period that provides a
window that the ground fault condition must
persist within for the controller to Alarm.
PTC PTC
Enable
79
Disable
Enable
Disable
Enables PTC based over-temperature protection
when used with external PTC sensors.
Phase
Reversal
Phase Reversal
80
Disable
Enable
Disable
Allows the user to prevent starting if the incoming
line phase sequence is not correct. The incoming
power lines are expected to be in an ABC sequence.
The controller will fault if power lines are out of the
ABC sequence.
Restart
Starts Per Hour
81
0…99
0
Limits the number of starts that can occur in a one-
hour period. This feature includes a “sliding
window” for the one-hour time period.
2 recomMended
Restart Restart
Attempts
82
0…5
0
Allows the user to enable the SMC-Flex to auto-
restart for up-to 5 attempts, other than an SCR
overtemp or motor overload fault. The start signal
must remain active for a restart to occur.
