The PT10 is a solid state sequencer designed to provide an adjustable duration 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. Up to three extender boards PT10EXT (10 outputs each) can be connected to the connector CON3. Two pressure switch control inputs are provided to control the operation of the timer. If connected to the D.P. SWITCH interrupt terminal (1) the timer will remember the last soleniod energised and continue with the next output. If connected to the full cycle terminal (2) the timer will complete the sequence and stop at the last output. The CLEAN UP feature will run the timer for a programmed number of complete cycles (0-255) after the baghouse fan is turned off. The clean up cycle is initiated by the opening of the auxiliary contact on the fan motor. A jumper wire must be fitted if clean up feature is not used.

SPECIFICATIONS:

• Input Voltage : 110 to 240 VAC, 50-60 Hz - refer to PT10-A for different voltage combinations
• Fuse : 2 Amp Slow 5x20mm
• No of Outputs : 1 to 10 (up to 40 with PT10EXT)
• Off Time : 1 to 999 seconds (in 1 second steps)
• On Time : 10 to 990 milliseconds (in 10ms steps to ensure zero crossing)
• Clean Up Cycle : 1 to 255
• Load Output : 2 Amp
• Operating Temp. : -10 to +55 degree centigrade

Other voltages and program changes are available to order.

DIMENSIONS:

The PT10 consists of a P.C. card 235mm long x 145mm wide and 35mm high with screw terminals for field wiring. A suitable dustproof plastic enclosure with clear lid or DIP enclosure is available.

WIRING:

Programming Instructions for PT Series Timers:

Press the Select button to illuminate the RED LED indicator to the left of the program display. Each time the select button is pressed the next specific function LED will illuminate. Once a function has been selected, press the UP and DOWN push button to set the desired number of valves, On Time, Off Time and Clean up Cycle. After completion press the select button to illuminate LED indicator "RUN". Now all settings are locked in, the program display will indicate "0" and the timer will go through the sequence. To check or change a specific function just push the Select button and illuminate the desired LED. The program display will display the current setting. In that position changes can be made and when completed push the select button to illuminate LED indicator "RUN". SEVEN SEGMENT PROGRAM DISPLAY: The program display will provide you with the following information:

• Display reads "0" = Sequencer is running
• Display reads "1" = Check pressure switch and setting of S1
• Display reads "2" = Clean Up Cycle Complete
• Display reads "3" = Full Cycle Complete
• Display reads "4" = Pressure Switch Interrupt
