Description
A GunSelect instruction that would change the state of the gun(s) is not positioned as an option on a motion line. This instruction will not complete any operation. Such and instruction by itself on a line in a program can not properly control the timing of the changes in the gun outputs. Note that if the gun is not programmed to be ON then a Gunselect can be on a line by itself. Note that this alarm may not occur in all cases.
Remedy
Move the Gunselect instruction onto a motion line and delete the stand alone instruction line. If needed add another motion line and record an appropriate position.
