• The impulse of the light barrier can
be checked via Service PCB XR24
(Order No. 1700-031-00); check
impulse of the LED drive motor
(XR24-II) or replace electronics.
• Check all cable connections.
• Check the motor for any mechanical
faults (e.g. turn the fan wheel).
• Set potentiometer to ca. 30s and
check amount of regeneration
material pumped.
• Light barrier on the drive shaft
(XR24), tachometer generator
(XR24-II) or electronics defect.
• Cable connections to Regenerati-
on Unit loose or disconnected.
• Regeneration pump motor
blocked.
• Regeneration time at
potentiometer set at 0s.
Remedy
• Check regeneration timer setting.
• Replace electronic parts.
• Refill the regeneration containers. If
there is still no improvement replace
all chemicals in the machine.
• Re-set pump operating time at
higher value.
• Drain chemicals from the machine
and clean thoroughly. Connect the
regeneration containers in the
correct positions and refill with fresh
chemicals.
• Clean non-return valve, replace if
required.
Check for correct positioning
• Lay the hoses with no twists or
bends.
• Observe film shelf-life date.
• Observe chemicals shelf-life date. If
shelf-life of chemicals is exceeded
do not use and dispose of
appropriately.
• Check the impulses of the light
barrier and the impulses of the roller
drive or replace electronics.
• Check all cable connections.
• Check the motor for any mechanical
faults (e.g. turn the fan wheel).
Possible causes
• Regeneration time set too long.
• Electronics do not switch off.
• Regeneration containers empty.
• Pump operating time too short.
• Regeneration containers or their
hoses are interchanged.
• Non-return valve of regeneration
pump stuck or wrongly
positioned.
• Regeneration hoses (from the
Regeneration Unit to the X-ray
developer) twisted.
• Film shelf-life exceeded.
• Chemicals shelf-life exceeded.
• Motor tachometer generator or
electronics defect.
• Cable connections to Regenerati-
on Unit loose or disconnected.
• Regeneration pump motor
blocked.
