As filter systems only function properly when cleaning of the steadily clogging filter elements is ensured, the filter control system has an important job. It controls the pulse duration and interval lengths between cleaning and must therefore be adjustable in accordance with the material properties of the bulk solids being conveyed.
To adjust the proprietary filter systems to meet the requirements of the digital world, WAM has developed “Connect”. The filter control system enables wireless data exchange between the filter control system and user by means of the GPRS or Wi-Fi module. With the communication with the user, which is monodirectional by SMS in the GPRS network or bidirectional in the Wi-Fi network, the user is alerted immediately if a problem arises with the filter system. When the preset alarm pressure is reached, the integrated differential pressure meter (MDPE) sends a problem message straight to the user so that he or she can take countermeasures and avert any damage to the system. Setting is done on a control panel with four membrane keys and an LCD display on the outside of the housing. Here 51 programs can be configured with variable parameters.
Like “Time”, “Connect” offers as standard the option of activating up to three solenoid valves and the board equipped for use of up to 15 solenoid valves. To eliminate errors in the connection of the dirty and clean air ducts, the system automatically identifies the type of connection, as a result of which installation and commissioning are simplified.
Both filter control systems are now available for use with new dust collectors and for retrofitting installed models.
