SEQUENCER WITH DIFFERENTIAL PRESSURE SWITCH Online shooting sequence: This page allows you to configure, at manufacturer level, the declogging order for an ONLINE declogging cycle. In an declogging process, it may be advantageous to declog the same “ramp” several times in the same cycle. By adjusting the number of ONLINE steps, it will be possible in the same cycle to assign one or more solenoid valves to different pulse sequence numbers.

If the SFX+V2 is equipped with the dust emission check option: outside the declogging cycle, the "dust emission" input is monitored. If a fault is indicated by the sensor for at least a period of T19, then the SFX+V2 displays a general dust emission fault (see fault check → dust emission fault).

If a filter is designed to have cells in maintenance, they are not declogged when they are in maintenance. If the compressed air is managed, the SFX+V2 does not declog the solenoid valves associated with a tank with a mini pressure fault or re-inflation faults.
SEQUENCER WITH DIFFERENTIAL PRESSURE SWITCH Online : ONLINE mode is available depending on the configuration. Declogging in ONLINE mode consists of actioning the solenoid valves according to the ONLINE shooting sequence configured (see Parameters → Online shooting sequence). When the run order appears, the cycle begins at step 1 of the ONLINE sequence. When the run order disappears, two cases: - If the choice is "declogging stop: end of cycle": the cycle continues until the last step of the sequence (corresponding to number of steps in the online sequence)
SEQUENCER WITH DIFFERENTIAL PRESSURE SWITCH Offline : OFFLINE mode is available depending on the configuration. Declogging in OFFLINE mode consists in isolating the cells according to the OFFLINE-CELL declogging sequence, then actioning the solenoid valves of this cell according to the OFFLINE-SV declogging sequence. (see Parameters →...
Also, when reset a mini pressure fault, the SFX+V2 authorizes inflation by acting on the isolation SV, and initializes time T8. The minimum pressure must be reached before the end of time T8 otherwise the fault is generated again, the tank is isolated.
The pulse on an declogging SV causes a pressure drop in the tank and initiates a time T9. If, at the end of time T9, the tank is not re-inflated, the SFX+V2 generates a re-inflation fault and isolates the concerned tank.
Note: The SPX50 sensor has the advantage of being able to quickly detect dust peaks on the one hand and simultaneously monitor the average emission rejection against an alarm threshold on the other hand. These two information are given to the SFX+V2 via a single relay (see instructions associated with the SPX50 dust emission control device).
Cell opening / closing faults : Depending on the configuration, the SFX+V2 can manage the opening or closing faults of the cells of a filter (in the case of OFFLINE operation for example).
