Corrective actions in case of defect
H1 ON Check fuse F1 and F2 on the Generator board.
-
If they are not blown, check the line voltage to
the board and to the unit. Replace the Generator
board if the line voltage is present and OK.
-
If blown, replace with new ones respecting the
value and types; perform a new exposure and
check if they blow again. If they blow, check, on
the Generator board, if V6 and/or V31 and V36
are short-circuited and in this case replace the
tubehead and Generator board. If not short
circuited, replace the tubehead.
H2 ON As per H1 above.
H3 ON If OFF, check fuse F3 of the Generator board.
-
If not blown, replace the Generator board.
-
If blown, replace it with a new one of the same
value and type, make another exposure and, if it
will blow again, replace the Generator board.
H4 OFF Check that connector X53 of the board is well
inserted. Power off the unit and power it ON again
after about 30 s; if the LED will glow again (it may
take some seconds), replace the board.
H5 OFF Check the correct insertion of X57; if it is correct,
replace the tubehead, otherwise insert it correctly
and make another exposure. Replace the tubehead
if it will glow again.
