Code SVGN-240: Up Panel Mis-detect:(Eq:%d,Ln:%d)

Cause: Upper panel detection distance is larger (gun more open) than max detect distance. where: max detect distance = pos.err.max + thk.nom + thk.err.max. This alarm occurs only during program touchup (not point touchup). Note: SVGN-243 ActDetDist:x.x, MaxDetDist: y.y is posted as cause code for SVGN-240." Remedy: Confirm that: 1. no obstruction exists between guntip and panel. 2. ensure that panel is present on correct position. 3. the master position for the gun axis is correct and the tips touch at the zero. 4. the tip wear amount is correct. Re-execute the tip wear measurement when the tip wear amount is not correct. If the above item is OK, confirm that: 1. nominal thickness in pressure schedule is correct. 2. OverThickness tolerance (on gun teach setup screen) is large enough. If the above items are OK, confirm that: 1. Max allowable Pos error (on gun teach setup screen) is large enough. If the above item is NG, the position error is made less than maximum allowable position error in the following ways. 1. Touch up correct position using jog or point touchup(not program touchup). 2. Increase maximum allowable position error on gun teach setup screen. Note: if initial position error is too large, program touchup cannot touch up. Fanuc recommends using point touchup(not program touchup) at the initial touchup.
