The PT6 from Ptronik is a solid state programable sequencer for dust extraction timer board,designed to provide an adjustable pulse to control the pulse valves on reverse jet dust collectors. The number of outputs, on time, off time and clean up cycle are programmed by the program buttons and displayed on the program display.
Two pressure switch control inputs are provided to control the operation of the timer. If connected to D.P.SWITCH interrupt terminal (1) the timer will remember the last solenoid energised and continue with the next output. If connected to the full cycle terminal (2) the timer will complete cycles (0-255) after the baghouse fan is turned off.
The clean up cycle is initiated by the opening of the auxiliary contact of the fan contactor. A wire must be fitted if clean up cycle is not used. The PT6 can be fitted with an optional On Demand Cleaner function to make the dust extraction timer board complete.
