P43 Controlled Fault Stop Enable PFN 12
LED Display 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 B - Fault Codes to determine if a fault may perform a controlled stop.
See Also Stop Mode (P15 / CFN 14) parameter on page 87.
