Fault reset details
●
If the Fault led is RED, the soft starter is in a fault condition
and will not recognize a START command. If a reset
attempt is unsuccessful, the fault is still present and must
be corrected
●
If the soft starter appear to have “tripped”, but the Ready
LED is illuminated and there is no new Fault code in
memory, verify that the soft starter has not stopped due to
a STOP command
●
Terminal “Permissive” must be energized (maintained) to
enable operation, but will not prevent a fault from being
reset. The Ready LED will not be illuminated without a
signal at the “Permissive” terminal
●
Terminal “Start” energized (momentary or maintained) to
issue START command. Signal duration must be a
minimum of 500 ms for the soft starter to recognize the
START command
●
Terminal “Permissive” is de-energized to issue STOP
command
●
LEVEL sense
●
Most commonly used START control parameter setting
●
Maintained “Start” energized:
– START command is present when terminal
“Permissive” is energized (maintained)
– START command is present when any fault clears and
is then RESET
– RESET function may be either AUTO or MANUAL
●
IMPORTANT NOTE: If the LEVEL sense parameter
AND the AUTO RESET parameters are selected, a
motor START command will exist if a 120 Vac signal is
present on terminal “Start” and terminal “Permissive”
and remains energized when the fault condition clears.
After a transient fault, this condition may cause the
motor to start unexpectedly
●
Momentary “Start” energized:
– Same as maintained
●
EDGE sense
●
Maintained “Start” energized:
– After a fault has been RESET the 120 Vac signal must
be removed from the terminal “Start” to enable a
START command. After a fault has been RESET,
re-energizing terminal “Start” (maintained or
momentary) will issue a START command
●
Momentary “Start” energized:
– If terminal “Start” is energized (momentary) by the
soft starter control system, the START signal must be
reapplied after the RESET has been accomplished
●
In either case above, terminal “Start” must be
de-energized momentarily if the RESET parameter is in
either MANUAL or AUTO to enable a START command
●
Thermal overload
●
After an overload trip—no restart is allowed until the
prescribed time period has elapsed
●
Thermal memory
●
This parameter is not the same as thermal overload
●
Parameter may be viewed in the monitoring menu
●
At 100% thermal memory the soft starter will stop with
a fault status LED
●
At 99% thermal memory a START command will be
allowed BUT, as soon as 100% is again reached, as it
will be during the start sequence, the soft starter will
again stop
●
Cycling 120 Vac control power will not zero the thermal
memory
