Protection Scheme Reset Procedure
DANGER
Reset Protection Scheme Caution
Failure to obey all safety precautions may cause death and equipment damage and drive
failure. Prior to resetting the protection scheme, read the section of this manual titled "Faults
and Alarms", and then contact Siemens technical personnel. ( 1-800-333-7421) Refer to the
Appendix "Service and Support".
Resetting the protection scheme
1. In the control section, reset the LFR / K1 using SW2 / S2 or keyed reset pushbutton. The
LFR / K1 N.C. contacts are immediately reclosed.
2. Initiate a "Drive Fault Reset". The control will not re-close M1_DOUT (NXGpro) if the fault
conditions still exist. Refer to the "NXGpro Control Manual" (A5E33474566) or the "NXGpro
+ Control Manual" (A5E50491925) provided with the drive.
DANGER
MV IP Breaker Enable
This contact must be integrated with input switchgear to deactivate the drive input medium
voltage upon the rare event of a secondary circuit fault. Failure to do so may result in death,
and equipment damage.
• Contacts close = Permissive to close breaker
• Contacts open = Trip breaker
Note
Given the amperage rating of the components used in the coordinated input protection
scheme, an additional customer pilot relay may be required.
