2 PILOT VALVES Description The Pilot Valve Assemblies have been designed for remote actuation of ASCO s Main Pulse Valves. The installer friendly layout, prewired solenoids are protected by a cast aluminum watertight and corrosion resistant enclosure. Three sizes are available for up to a group of 12 valves with optional anti-frost heater. All ASCO s pilot valves and enclosures offer long life and dependability to produce quality controls for today s technically advanced dust collector system. For hazardous locations an explosion-proof model is available.

4 2 WAY HIGH FLOW (MAIN PULSE) VALVES Description Series 8353 die cast aluminum, diaphragm operated valves are specially designed for reverse jet type dust collectors. High flow, long life and fast opening combine to produce a superior design for dust collector systems. Operation When the pilot valve is opened, air bleeds from the top of the diaphragm through the pilot valve orifice, opening the main valves. When the pilot valve is closed, air is trapped above the main diaphragm closing the valve. Selection of proper pilot valve orifice is important.

7 SEQUENTIAL CONTROLLER Description The ASCO Sequential Controller has been designed to operate the ASCO pilot valves used on dust collector equipment. Light emitting diodes (LED s) provide visual indication of which pilot valve is being energized as well as Power On indication. The number of sequenced steps is adjustable from 2 through 10. Method of Operation Controls are provided to adjust the length of time between valves being energized (Pulse Frequency) and the length of time that the valve is energized (Pulse Duration). Silicon semiconductor components control all timing and logic functions. Two independent methods of starting and stopping the Controller TRI-POINT PRESSURE SWITCH are provided. The first method will automatically stop the sequence and reset the Controller to the first valve position whenever AC power is removed and then reconnected. The second method is by a remote control contact connected to the terminals provided. When the remote contact is opened, the sequence stops. When the remote contact is reclosed, the sequence continues from the previous position. Specifications Input Voltage Range: 102 to 132 volts, 60 Hz. Input Fuse: 3 amp, 125 volt, type AGC. Pulse Duration Range of Adjustability: 20 to 200 milliseconds. Number of Sequenced Steps: 2 through 10, adjustable in field, (factory set at 10). Temperature Range: Operating: -10 F to +130 F (-23 C to 54 C) Storage: -20 F to +150 F (-29 C to 66 C) Repetitive Accuracy on Time Sequences: ±5% SEQUENTIAL CONTROLLER CAT # 214B281 CSA CERTIFIED ENCLOSURES CAT # Current Ratings per Sequence Step: Maximum Inrush Current: 7.5 amps at Hz. Maximum Continuous Current: 2.0 amps at Hz. (NOTE: Solid-state elements require that minimum continuous current per sequence step must not be less than amperes. Consult factory for special rating requirements including operation below amperes). Dimensions, open type: 9 high x 7 wide x 5 deep. Mounting: Four 3/4 long stand-offs are supplied for mounting within enclosure. Load Fuse: 2 amp maximum required (CLOSED) (WINDOW) CSA & UL APPROVED TYPES 3, 4X & 12 Description ASCO S-Series pressure switches consist of a switch unit and a transducer unit. They can be ordered separately for customer stocking and/or field assembly or as a complete factory assembled unit. Switch S-Series pressure switch units incorporate the unique ASCO TRI-POINT alternating fulcrum balance plate to control the operation of one or more electrical snap action switches. The electrical snap action switch together with the adjusting mechanism is a fully tested, self-contained, separate subassembly. Transducer Transducer unit incorporates a diaphragm/piston type pressure sensor, and is also a fully-tested, self-contained, separate subassembly. Operation When pressure is applied to the transducer it is converted into movement of the piston. This piston movement is then used to control the operation of the electrical snap action switch in the switch unit. Features Visual adjustment scales in psi and bars. External adjusting nuts. Separate electrical, pressure and adjusting chambers. 1 / 4 NPT connection SPECIFICATIONS ADJUSTABLE DEADBAND TRANSDUCER UNITS Adjustable Adjustable Air or Gas Operating Proof Deadband At Aluminum & Range Pressure Mid - Range General Purpose Watertight 2 Explosion Proof Buna N (In.W.C.)
