Gun, LED1 Off 1. Improper or No input line volt-
age at 6PL
2. Defective 24 VDC power sup-
ply 2PS
1. Ensure voltage across terminals 1 and
3 of connector 6PL is between 90 and
264 VAC.
2. Voltage across terminals 1 and 6 of
plug 6PL of power supply 2PS should
be 24VDC. If not, replace power sup-
ply 2PS.
