    Operation Cleaning: LED lights up while the filter is being cleaned. Pulse LED: LED lights up when a valve is actuated. 17-18 Valve error: • LED flashes if the valve current is interrupted (< 15 mA). • LED flashes to indicate valve overcurrent (> 1.2 A). LEDs 11, 12 and 17 to 18 light up continuously if the controller detects that the cause of a fault has been cleared but the fault signalling relay is programmed with a HOLD function.

  • Page 32: Analouge Output

    Analogue Output ♦ Valve Parameters 5 Analogue output You can change the current output from 0-20 mA to 4-20 mA with the ‘A.out’ parameter in the Delta P menu. The analogue output always signals the actual differential pressure that is shown on the display. 20 mA is indicated if the full-scale value is reached.

  • Page 33: Proportional Interval Time

    Valve Parameters 6.2.3 Proportional interval time You can set an interval time that is proportional to the differential pressure with the ‘P.PAu’ parameter in the Valve Parameters menu. The ‘PAuS’ parameter corresponds to the minimum interval time and the ‘P.PAu’ parameter to the maximum interval time. The minimum interval time triggers pulse actuation at a differential pressure ≥...

  • Page 34: Pulse Actuation Sequence

    Valve Parameters 6.3 Pulse actuation sequence Menu name: (FolG) The pulse actuation sequence determines the order in which the valves are actuated. In a filter with several chambers, it is thus possible to actuate one valve cyclically in each chamber. You can choose which of the following cleaning modes is best suited for your particular application: 1.

  • Page 35: Multiple Pulse Actuation

    Valve Parameters 6.5 Multiple pulse actuation Menu name: (Anz.P) ‘Multiple pulse actuation’ means the same valve is actuated several times consecutively. The number of pulses can be selected in the menu (AnZ.P). If you set this number to 1, multiple pulse actuation is deactivated.

  • Page 36: Relay Functions

    Relay Functions 7 Relay functions The three relays integrated in the filter controller have freely selectable functions. The default settings are as follows: Relay 1 - Operation Relay 2 - Group fault Relay 3 - All cleaning modes The possible settings are shown in the table below: Status message Error messages Cleaning messages...

  • Page 37: Restoring The Default Settings

    Default Settings 8 Restoring the default settings All user parameters are permanently stored in an EEPROM. You can restore the default settings if necessary (e.g. if the data in the EEPROM is lost or the settings are programmed incorrectly). To do this, press the ENTER and MODE keys simultaneously and hold them down while you switch on the filter controller.

  • Page 38: Test Functions

    Test Functions 10 Test functions 10.1 Lamp test Menu name: (L.tSt) The ‘Lamp test’ function causes all LEDs and all segments on the 7-segment display to flash. You exit the function by pressing the MODE key. 10.2 Display inputs Menu name: (EInG) Each input is represented by a digit on the four-digit display as H = high signal (+24 V) or L = low signal (0 V).

  • Page 39: Error Messages

    Error Messages Error messages 11.1 Fault LEDs If a fault occurs, it is indicated by a flashing LED. You acknowledge the fault either by pressing the ENTER key or with the ‘Acknowledge fault’ input. The error message (relay) is simultaneously reset.

  • Page 40: A Inputs

    Appendix A Inputs A. Inputs The filter controller has four optocoupler inputs: Terminal 28 = Stop Terminal 29 = Rapid cleaning Terminal 39 = Post-cleaning Terminal 40 = Acknowledge fault Stop: Prevents the valves from being actuated and overrides the post-cleaning function.

  • Page 41: B Outputs

    Appendix B Outputs B Outputs B.1 Valves The filter controller has 24 outputs for connecting magnetic valves. The number of valves used must be set (default = 24). The valve outputs are rated for 24 V DC and 1 A. The maximum actuation time (pulse) must not exceed one second and the minimum recovery time (interval) must be greater than or equal to the pulse time.
