A sequence controller system for regenerating a plurality of water treatment units in a water treatment plant. Each of the water treatment units has a timer and a multi-port valve for sequencing each of the water treatments units through successively repeating cycles of service and regeneration. The sequence controller system has a priority specifying means for setting the time intervals by which only one of each water treatment unit that is ready for regeneration, at the same time, is permitted to begin its regeneration cycle. The sequence controller system also has a common interlock connection between all of the water treatment units to lockout all of the water treatment units from beginning their regeneration cycles except for the water treatment unit that has been priority specified by having the lower set time interval before beginning its regeneration cycle.

An adjustable encoder includes a source generating a first signal and transmitting it to a transducer element for generating an electrical signal responsive to the first signal. An object is rotated between the source and the transducer element so as alternately to block and to permit or unblock the path of the first signal from its source to the transducer element. The transducer element and the source are simultaneously movable parallel to the plane of rotation of the rotatable object, so that the exact timing of interruption of the first signal can be adjusted while the encoder is in operation.
