Err 22 Preparation The exposure/
preparation
filament current is
not stable.
If the exposure filament level is OK, it
should stabilize within 3 s.
• Check the voltages on D4, +60 V,
+15 V and +5 V (see page 160**).
• Check the connection between
D4 and the filament transformer
(K60) (see page 160**).
• Check the trigger pulses in
measurement point "FIL" on D4
(see page 160**).
• Check the value in "FIL_VAL" on
D1. The value must be stable in the
standby filament. After change-
over to preparation, the value
should stabilize again.
• See also "P01 - Filament test".
