12.1 XR 24, XR 24 II, XR 24 NOVA
Check regeneration at start of operation
• Main switch ON
• When the appliance is switched on the
Regeneration Unit must be activated and
developer and fixer will be pumped to the
baths of the X-ray developer.
• Check the appliance for leaks.
Check regeneration impulse for film
length
• Main switch ON
• Set fast forward to ON (film transport set to
3 min.). Lay a film in the film intake such
that the film intake flap is activated but so
that the film is not transported. After
approx. 8 min. the regeneration pumps
should switch on and developer and fixer
should be pumped into the baths of the
X-ray developer.
• Check the appliance for leaks.
Check regeneration pump performance
The developer and fixer pumps
should transport the same amount of
liquid into the baths of the X-ray
developer.
• Fill two measuring beakers with the same
amount of water (approx. 0.5 liter). Place
these in the Regeneration Unit and place
the two hoses from the regeneration
containers into the measuring beakers.
Check that the pumps feed
the identical
amount
of water.
If necessary alter the pump transport
settings.
See section 13. Setting regeneration
pump piston stroke.
12.2 XR 24 PRO
A processor in the electronics of the
XR 24 PRO stores the complete
developing time, therefore setting
option selection is not required.
Check regeneration impulse for film
length
• Switch on the X-ray developer and select
program „Endo“ (film transport time 2:45
min.).
• Lay a film in the film intake such that the film
intake flap is activated but so that the film is
not transported. After approx. 7 1/2 min.
the regeneration pumps should switch on
and developer and fixer should be
pumped into the baths of the X-ray
developer.
• Check the appliance for leaks.
Check regeneration pump performance

the two hoses from the regeneration
containers into the measuring beakers.
• The pumps can be activated via the
Service Routine of the XR 24 PRO, in order
to check the amount of liquids transported.
