Terminals 1 and 5 may not be assigned.
  • Page 99 99/105 | S-BM2 S-BM2 Handling & Manipulation The S-BM2 is made of boards and can thus be considered fragile. Handling and manipulation must be done with care. Smaller dimensions can be manipulated and placed in the installation opening by two persons. Bigger dimensions are supplied with wooden blocks, those serve as support for suitable lifting equipment (forklift, crane). Please follow both textual and graphic instructions: 1.Unpack the damper and place it in vertical position.

Operation Manual After installation, it is necessary to adjust the damper into its operating position “closed”. In case, that the damper is used for extraction of pollutants, adjust the damper into its operating position “open”. ...
  • Page 103 103/105 | S-BM2 Functionality Check Switching the damper to the “open” position: • The blade must come to the fully open position within 60 seconds and must remain locked. • After reaching the end position of the blade, the appropriate signaling circuit must switch on – wires S1 and S2 must be connected.
