The STM11-6DC is a solid state programmable timer for dust collectors. The sequential timer is designed to provide an adjustable duration pulse to output drivers in a continuous cycle. The time interval between pulse outputs is set by the STEP potentiometer, the pulse duration is set by the PULSE potentiometer. Power ON and each output pulse time is indicated by LEDs.
Two terminals labelled D.P.S.W. (differential pressure switch) are provided for ON DEMAND cleaning. After pressure switch contact closure, the timer will stop the sequence. When the contact opens the sequence continues from the previous position. Number of outputs is programmed by the SELECT STEPS switch.
