Description
An inavlid binary valve pressure was programmed in the teach pendant program.
Remedy
Check the P= value of the current line of the teach pendant program. The smallest valve pressure allowed is 0. For digital weld controllers, the largest pressure number allowed depends on the width of the Valve Pressure group output. If this GOUT is 4 I/O points wide, then the maximum pressure is 15. If the GOUT is 5 I/O points wide, then the maximum pressure is 31. For serial weld controllers, the maximum pressure is 15. Re-program the P= value in the teach pendant program.
