Description The Auto Fault Reset Time parameter sets the time delay before the starter will automatically reset a fault.
For the list of faults that may be auto reset, refer to Appendix B - Fault Codes.
z

See Also Appendix C - Fault Codes on page 205.
Auto Reset Limit parameter (PFN23) on page 103.
Auto Fault Reset Count Limit PFN 24
LCD Display
Range
Off, 1 – 10
(Default Off)
Description
The Auto Reset Count Limit parameter sets the number of times that an auto fault reset may be performed.
Once the number of auto reset counts have been exceeded, the starter will lockout until a manual fault reset is
performed.
If less than the maximum number of auto resets occur and the starter does not fault for 15 minutes after the
last auto fault reset occurred, the counter will be set back to zero. The auto reset counter is also set back to
zero when a manual fault reset occurs.
See Also Auto Reset parameter (PFN23) on page 102.
Controlled Fault Stop Enable PFN 25
LCD Display
Range
Off – On
(Default On)
Description
A Controlled Fault Stop Enable can occur if this parameter is "On". The controlled stop will occur before the
starter trips. During a controlled fault stop, the action selected by the Stop Mode parameter is performed
before the starter is tripped. This prevents the occurrence of water hammer etc. in sensitive systems when a
less than fatal fault occurs.
z
NOTE:
All relays except the UTS relay are held in their present state until the stop mode action has been
completed.
z
NOTE: Only certain faults can initiate a controlled fault stop. Some faults are considered too critical and
cause the starter to stop immediately regardless of the Controlled Fault Stop Enable parameter.
Refer to Appendix C - Fault Codes to determine if a fault may perform a controlled stop.
See Also Stop Mode parameter (CFN15) on page 85.
Appendix C - Fault Codes on page 205.
