Operation
Automatic replenishment
Depending on the processed amount of films the chemicals are replenished auto-
matically. This is done by pumping chemicals from the replenishment containers.
The surface area of the film processed is calculated on the basis of the film detec-
tion switch at the film feed. For every 40 seconds that the film detection switch is
activated, a regeneration cycle of 13 seconds is started; thus a volume of fresh
chemicals is introduced that is adequate for the film length processed. This corre-
sponds to a regeneration rate of 600 ml pro m
2
of film at a film width of 35 cm. The
chart below shows the replenishment rate in ml per m2 film surface in relation to
film width and setting of the pump.
