7.6.3.3 N-, Collimator- or sensor swap not working
• Check +5V and +24V voltage indicators of stepper
modules
 If indicator is on, m24V voltage
from J3311, J3313 or J3314.
  Replace R3300 if there is no volt-
age.
 If indicator is on, m24V voltage
from J5101.
  Replace cable between J5101
and R3300 if there is no voltage.
If both indicators are on then follow motion con-
trol trouble shooting guide.
If +5V indicator LED is not on but R3220 is ac-
tive, replace cable between stepper module
(J5101) and the R3200.
 If indicator LED still does not come on,
replace R5100.
If +24V indicator LED is not on, check that
+24V_SD (D9) indicator LED on the R3220 is on.
 If +24V_SD indicator is not on, check that
+24V indicator LED on the EG200 is on.
  If +24V indicator LED on EG200
is not on check that +24V indica-
tor LED on EA100 is on.
 If not on, see chapter
7.6.3.1.
 If on, see description in
the introduction above.
  If 24V indicator LED on the
EG200 is on, replace cable be-
tween J3206 and JG211.
 If +24V_SD indicator LED is on, replace
cable or R5100.
