11.2 XR 24 II and XR 24 NOVA
The controller for the Regeneration Unit of
XR 24 II
and
XR 24 Nova
is not integrated
into the main board. For these models the
controller can be found on the PCB (24),
Order No. 1700-212-00, which is slotted onto
the main board.
The slots for this printed circuit board can be
found in the upper left corner of the main
board, and are marked X13 and X14.
Before slottting PCB into position
(24) remove power supply to the
X-ray developer.
Setting for regeneration and pump operating
time are carried out on the PCB (24).
Switch „X3“
Regeneration on appliance operation
ON/
OFF
• If switch (27) is set to
ON
, regeneration on
appliance operation is
additionally
activated and when the X-ray developer is
switched on regeneration occurs.
• If switch (27) is set to
OFF
, regeneration
occurs only after 1.3m of film has been
developed.
Switch „X4“ 50% / 100%
• If switch (26) is set to
60s
then the
maximum pump running time of the
Regeneration Unit is 60s.
• If switch (26) is set to
30s
then the
maximum pump running time of the
Regeneration Unit is halved to 30s.
Potentiometer P1 Reg.-time
The amount of chemical transported to the
X-ray developer depends on the pump
running time of the Regeneration Unit.
The potentiometer (28) can be used to set
the pump time from >0s to <60s (<30s).
The pump operating time is factory-set at
30s. In this time approx. 190ml fresh
developer and fresh fixer are pumped to the
X-ray developer baths. If further adjustment
is necessary the potentiometer knob (28)
can be used to change the pump operating
time.
