Sequential controller offered by IFF provides a timed sequential energization of pilot solenoid valve which is being used in the pulse value assembly. To start and stop the controller two independent methods are provided and the number of sequenced steps can be easily adjusted from 2 to 10 along with the length of time between valves (pulse frequency) and next valve is energized according to pulse duration.

Implementation of first method stops the sequence and reset the controller to the first valve position whenever AC power is removed and then reconnected. In the second method, a remote control is used to connect to the terminals and when this connection is opened the sequence automatically stops and when the remote contact is reclosed the same sequences continues and eliminates repeated cleaning of filter bags.

The card is protected in steel coating with enamel paint enclosures as per IP65. The fire-proof enclosure can be provided upon request by IFF. The differential pressure switch can work with sequential timer to operate the system in demand mode from a remote location. A unique combination of DP switch controlled sequential timer is provided for processes with variable load during operation .The cleaning is initiated upon reaching high DP and stopped upon achieving low DP .This arrangement saves compressed air and also enhances filter bags’ life. DP switch is not a part of this system.
