  • Page 51: Nb Simultan. Pulses

    NB SIMULTAN. PULSES In ONLINE dust removal, it can be interested to declog several “rows” simultaneously (1 to 16). If the arrow is placed on NB SIMULTAN.PULSES and if the button is pressed, the following display appears: Possible adjustment range Note: Protected by code! appears if protection is activated.
  • Page 52 3 SIMULTANEOUS SHOTS: Note: the T16 time value is adjustable (see T16 : SIMULTAN.PULSES) or fixed (fixed value at the programming). (T16 from 10 to 255 1/100 of second). As regards a configuration with slave boxes, the time T16 is reduced to the minimum and its value is that imposed by the link.

  • Page 53: Nb Step Online

    NB STEP ONLINE It may be of interest within a dust removal process to perform several dust removal operations on the same "ramp" within the same cycle. By adjusting the number of ONLINE steps, one or several solenoid valves can be allocated to different pulse order numbers within the same cycle.

  • Page 54: Online Cycle

    ONLINE CYCLE This menu step is used to configure the dust removal order for one cycle for an ONLINE dust removal filter. Principle: a pulse order number is associated to a solenoid valve (or several SV in the case of simultaneous shots).
  • Page 55 Note: if running with simultaneous shots, display is: - If 2 simultaneous shots: - If 3 simultaneous shots: Important: in the event of simultaneous shots, and in a configuration with slave boxes, the simultaneous shot of several ways in the same cell is not prohibited by the setting. Take care not to choose several ways on the same box in the same step because, in this case, only the first way requested can be taken into account.

  • Page 56: Nb Step Offline-Way

    NB STEP OFFLINE-WAY It may be of interest within an OFFLINE dust removal process to perform several dust removal operations on the same "ramp" within a cell. By adjusting the NB STEP OFFLINE-WAY, one or several dust removal solenoid valves can be allocated to different pulse order numbers.

  • Page 57: Offline-Way Cycle

    OFFLINE-WAY CYCLE This menu step is used to configure the dust removal order in a cell. It is the same for all cells in the filter. Principle: a pulse order number is associated to a dust removal solenoid valve. Dust removal in a cell starts on the pulse with order number 1 and ends on the pulse with order number = to the parameter NB STEP OFFLINE-WAY.

  • Page 58: Nb Step Offline-Cell

    NB STEP OFFLINE-CELL It may be of interest within an OFFLINE dust removal process to perform several dust removal operations on the same cell within a cycle. By adjusting the NB STEP OFFLINE-CELL, one or several cells can be allocated to different cell dust removal order numbers.

  • Page 59: Offline-Cell Cycle

    OFFLINE CYCLE - CELL This menu step is used to configure the dust removal order of the cells in a cycle. Principle: a cell in which dust removal is to be performed is associated to a cell cycle number. A dust removal cycle starts with the cell cycle number 1 and ends with the cell cycle number = to the NB STEP OFFLINE-CELL.

  • Page 60: A/C Threshold

    A/C THRESHOLD In the case of a configuration with slave boxes equipped with compressed air pressure sensors: this menu step allows the adjustment of the A/C mini header pressure threshold, the A/C operating pressure threshold, and the value of the fall pressure during a shot. If the arrow is placed on A/C THRESHOLD and if the button is pressed, the following display appears:...
  • Page 61 - A/C OPERATING PRESS. A/C operating pressure threshold allows controlling the headers pressure during the phase of dust removal in order to control the consumption during a shot and the re-inflation after the shot. This threshold is used to create header re-inflation faults and no consumption header (see re-inflation fault and Pressostatic filter cleaning solenoid valve not open fault).

The operating responses, the operating statuses, etc which may be given by the SFX+ are shown and detailed in the wiring diagrams.

  • Page 86 PUT ON SERVICE Aim: To prepare the filter → opens all the cells authorises header inflation. Switching on (=put on service) requests that the headers are inflated to open the header valves. Switching on (=put on service) is effective after inflating all the headers (service pressure reached) or after a timeout If at the end of switching on (=put on service), a header is not at its service pressure, but has reached the minimum, no faults are generated.
  • Page 87 X - FAULT CONTROLS GENERAL DETAILS The SFX+ can manage the following fault controls: - Electrical fault - dust removal solenoid valve cut off - dust removal solenoid valve permanently passing (1 per module) - dust removal solenoid valve permanently passing (1 per slave box) - Cell opening fault - Cell closing fault - Mini pressure fault...
  • Page 88 ELECTRICAL FAULT CONTROLS 2 types of electrical fault controls are managed by the SFX+. - The dust removal solenoid valve cut off electrical fault: In this case, when there is a pulse on a solenoid valve, the SFX+ NETWORK checks that a current does pass into the solenoid valve - output circuit.
  • Page 89 - The permanent consumption electrical fault: In this case, the SFX+ NETWORK checks that no current is flowing in the outputs - solenoid valve when there is no pulse on the solenoid valves. If there is current consumption, the SFX+ NETWORK generates a short circuit electrical fault. The location can only be given at module or slave box level as the outputs of the same module or of the same slave box all have the same current control.
  • Page 90 CELL OPENING / CLOSING FAULT CONTROL The SFX+ NETWORK can control opening or closing faults of the cells of a filter. It receives cell position information via its inputs through limit sensors. The position of the cells is determined by the SFX+ NETWORK.
  • Page 91 MINI PRESSURE FAULT The compressed air headers associated to the cells forming the filter are each fitted with a pressostat and an isolation valve on the compressed air inlet. A min pressure level is permanently checked by the SFX+. If the compressed air pressure falls below this limit, the SFX+ generates a min pressure fault and isolates the header by controlling the isolation valve.
  • Page 92 DUST REMOVAL SOLENOID VALVE NOT OPEN PRESSOSTATIC FAULT The compressed air headers associated to the cells forming the filter are link to a pressure sensor. This is capable of detecting a pressure drop in the headers when a pulse is given on one of its dust removal solenoid valves.
  • Page 93 REINFLATION FAULT The compressed air headers associated to the cells forming the filter are each fitted with a differential pressure switch and an isolation valve on the compressed air inlet. The differential pressure switch measures a pressure limit adjusted for optimised dust removal. This limit must be reached to control the pulses on the dust removal solenoid valves.
  • Page 94 DUST EMISSION FAULT Depending on the configuration, a dust emission check can be carried out. This involves: - checking that there is no appearance of a dust emission downstream during a shot on a filter cleaning solenoid. - checking that there is no appearance of a dust emission outside of a cleaning cycle This check is carried out from a logical input “dust emission”...
  • Page 95 Checking outside of a cleaning cycle: Outside a cleaning cycle, the input “dust emission” is monitored. If a dust emission is detected, a “general dust emission” is generated. Notes: The dust emission detection is temporized (value of T19 time to adjust from 0 to 255 seconds in the SELECT menu).
  • Page 96 DIALOG. FAULT This type of fault appears when becomes a dialogue problem between: The central unit card and a module The central unit card and a slave box The central unit card and a MDPP2000 The link faults are reported in the fault visualisation mode. A display bringing together all the link faults present (up to 8 of each type) is placed in the last position of the fault stack: in the above display example: - link fault on the modules n°20, 21 and 23...
  • Page 97 XI - GENERAL INSTRUCTIONS FOR THE USER - The electrical installation upstream of the SFX+ equipment must comply with the provisions of power surge 2. - SFX+ equipment is generally fitted in boxes or cabinets with a degree of protection of IP 55. If this is not the case, the level of protection must be sufficient so as not to exceed pollution degree 2.
