4. ONAL FUNCTIONS 1 Differential Pressure AP A AP function is incorporated into the PCB for use in conjunction with a Differential Pressure Switch to control the cleaning cycle of DS Cover Controller s on Dalamatic installations Jt is not suitable for use with Sintamatic Siloair or Unicell filters Tappings for the differential pressure switch are taken from the clean and dirty sides of the dust filter For more information refer to SCS drawings 63000 64001 50200 and or PSI 200 whichever 15 or are applicable AP Operation When a DS Cover Controller is governed by a differential pressure switch LED L11 only will be permanently lit Once a signal from the pressure switch is received L12 will also light up and 1f the signal continues without interruption for a minimum of 20 seconds the P circuit will be initiated a normal cleaning cycle will follow LED s flashing with each pulse If the pressure switch signal ceases during the cycle L12 will go outbut the cycle will be completed leaving the controller reset ready for the next signal If the pressure switch remains open a further cycle will commence and so on 2 Intermittent Int This function is primarily intended for interlocking with other associated controls such as the fan starter With a normallly closed NC contact connected to these terminals LED s L11 L12 and L13 will be lit When the contact opens e g upon energisation of the fan or blower L13 will go out and
