The SPS No Response alarm on the QUICK LOAD SERVO S3 occurs due to a communication problem between the remote control station and the LNS PLC. To fix this error:
1. Check the connectors between the PLC and the remote control station inside the cross piece to ensure they are correctly attached. 2. Verify continuity between the PLC and the remote control station.
These steps help restore proper communication and resolve the error.

Common Issues he Quick Load Servo S3 is designed to be a user-friendly, simple, and reliable bar feeder, covering a range of diameters ¼” to 4 ¾”. Although easy to use, including extremely quick changeovers and the capability for unmanned operation this unit is not flawless.
Description: The Quick Load Servo S3 uses a LNS PCD2 controller (PLC) to send/receive inputs/outputs. The PLC is powered by a +24VDC input supplied by a transformer. The input supply voltage must be regulated to ensure proper functioning. The remote control station, which is used to send/receive data back and forth with the PLC, is powered by the +24VDC on the PLC.
Vibration Issues The term “vibration” is being used regarding the Quick Load Servo S3, to indicate that the RPM performance of the lathe is physically deteriorated, to the point of creating an unbalanced rotational oscillation of the bar stock, within the confines of the spindle of the lathe that is detrimental to the machining process.
Hitting back of spindle then recalibrate the loading table, refer to Alignment Procedure pg. 3-3 Calibration of the Loading Table pg. 3-31. Hitting back of • Verify the correct collet/chuck is installed for the material being run. clamping system QUICK LOAD SERVO S3...
This application requires that the lathe be equipped with a pull-to-close type clamping system. If a push-to-close type clamping system is used then the “Feed with help of the turret” application must be selected. It is recommended by LNS that when feeding without the help of the turret that a dead-length, parallel gripping type clamping device be used.

Do you have a question about the QUICK LOAD SERVO S3 and is the answer not in the manual?
Questions and answers
LNS BARFEEDER sps no response , how do i fix this error
The SPS No Response alarm on the QUICK LOAD SERVO S3 occurs due to a communication problem between the remote control station and the LNS PLC. To fix this error:
1. Check the connectors between the PLC and the remote control station inside the cross piece to ensure they are correctly attached.
2. Verify continuity between the PLC and the remote control station.
These steps help restore proper communication and resolve the error.
