Abstract
Interface for a silver recovery unit (11) for indicating the operating condition of at least one pump (9a, 9b). A sensor (10) for detection of the operating condition of the pump (9a, 9b) is installed outside the at least one pump (9a, 9b) such that during installation an intervention in the electronic unit (24) of the pump (9a, 9b) or in the pump (9a, 9b) itself is avoidable. The output signal of the sensor (10) is passed to a series-connected electronic circuit (400) that comprises a series connection of an amplifying means (40), a first filtering means (41), a rectifying means (42), a second filtering means (43) and a comparator (44).
Claims8
A device for interfacing between a film developing device and a silver recovery unit for checking the operating condition of said film developing device, said film developing device having at least one electric motor-driven pump, a plurality of liquid lines and a pump/machine control unit, and at least one sensor for detection of the operating condition of said film developing device is installed outside the at least one pump of said film developing device such that said sensor is fastened directly to a housing wall of said motor-driven pump.
