8. AC line voltage is out of specifica-
tion during an exposure. Check
the capacitor (C9-C12 and C13-
C16 on single-phase units, C1-C4
on SE units, or C9-C12 and C13-
C16 on three-phase units) voltage
is within range (i.e., 350 to 440
VDC).
9. Verify that all grounds are good
(JP2-JP9 installed or shorted on
Logic Board A1 (AY40-006S).
10. Verify that the power is sufficient
to support the exposure (i.e.,
check for weak AC Line).
Collimator Automatic collimator not respond-
ing (only appears on systems
using an automatic collimator).
1. Positive beam limitation (PBL) cir-
cuit is open; check PBL cable con-
nection between generator and
