Two-step Fastening>
P
Two-step fastening will be used primarily for joints that have a requirement to synchronize with
another spindle during the final stage of the rundown or require joint conditioning.
1.
Once RAMP DOWN START TORQUE is reached or FREERUN REVOLUTIONS expires,
the system will switch from FREERUN SPEED to 1ST SPEED and continue to fasten to 1ST
TORQUE/ANGLE.
2.
The system will fasten to the 1ST TORQUE/ANGLE value during the specified 1ST TIME.
1ST TORQUE/ANGLE must be reached within the 1ST TIME limits or a reject will occur.
3.
Upon reaching 1ST TORQUE/ANGLE, 1ST TIME ends and 2ND TIME begins. 1ST
TORQUE/ANGLE is the shift point to 2ND SPEED and the synchronization point prior to
commencing the next step.
4.
Upon reaching 2ND TORQUE/ANGLE the system with shift to 3RD SPEED. The system will
then fasten to STANDARD ANGLE. STANDARD ANGLE must be reached within the 2ND
TIME limits or a reject will occur.
