LNS America, Inc. for assistance and the message has already been cleared. On certain lathes, once the bar feed sends an alarm to the machine, the machine will in return send an emergency stop alarm to the bar feed which overrides any bar feed alarms.
The Emergency Stop Line Open alarm occurs whenever the PLC does not detect input (I0.0). The problem is generated anytime the safety circuit contactor (K1) is not energized and all safety switches are in operating position. (Refer to the Quick Six Instruction Manual).

Common Issues he Quick Six is designed to be a user-friendly, simple, and reliable bar feeder, covering a range of diameters 5/16” to 3 1/8”. Although easy to use, including extremely quick changeovers and the capability for unmanned operation this unit is not flawless.
Description: The Quick Six 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.
Press the “STOP” key on the remote control station and proceed with changing the parameters. Multiple Bars have been Loaded into the Channel Two bars loaded at a time Cause Solution Adjust switch SQ2. See pg. 3-14 for the procedure to Switch SQ2 is out of adjustment. properly adjust the switch. QUICK SIX...
The proper guiding elements should be used to provide minimal gap between the I.D. of the elements and the O.D. of the bar stock diameter. Should not exceed 10mm overall gap (5mm per side). LNS recommends running ISO 100 hydraulic oil in the bar feed. In certain cases, a thicker oil (ISO 150) may produce better results when guiding profiled material.
