SSPET5 3.1. General The single conveyor unit functions according to the principle of suction conveyance. A high-performance turbine, mounted permanently on the device, provides for the vacuum that is required to convey the material into the separator. In the separator the material is separated from air. After the conveying time is finished the turbine is switched off and the material emptied into the material intermediate hopper.
SSPET5 3.2. Controller SSE The setting for the conveying time and the line clear time are made via the keys (A1: “change-over” key, A2: “arrow key”) on the front of the control system. The values which have been set will be displayed on the display (B). The values which have been set are maintained after the machine has been shut off. 3 LEDs indicate the respective modes of operation: cleaning (C), conveying (D), line clearing (E). The conveying time can be set from 1 to 99 seconds.
SSPET5 If a material clearing valve has been installed (option) residues of flowing material will be cleaned from the conveying line during the line clear time. If a disturbance occurs in the unit, an alarm message will be issued (option, only if the alarm indicating device has been activated). & An “E” appears in the display and an error number. SM4-630 The alarm indicating device (signal siren, horn) reacts.
SSPET5 3.3. Controller SSP The setting for the conveying time and the line clear time are made via the keys (A1: “change-over” key, A2: “arrow key”) on the front of the control system. The values which have been set will be displayed on the display (B). The values which have been set are maintained after the machine has been shut off. 3 LEDs indicate the respective modes of operation: pulse duration (C), time interval (D), without function (E). The pulse duration can be set to 0.5, 1.0 or 1.5 seconds.
