10 ALS 4.0 XE P R O D U C T M A N U A L EN 2.4 Sensors There are two sensor sets in the ALS 4.0. They are used to control the feeding and clamping of the lumber. 2.4.1 Edge Detect Sensor (EDS) This is a set of through-beam sensors located in the L1 feeder. The receiver, shown on the left in the picture below, is embedded in the rollers of the L1 Pusher. EMITTER RECEIVER Figure4 The emitter, on the right, is in the rollers of the back fence directly opposite the receiver. When lumber passes it breaks the LED beam between the emitter and receiver which signals the computer that the trailing edge of the lumber has exited L1. 2.4.2 Lumber Present Sensor (LPS) This is a set of through-beam sensors located in the L2 feeder. The lumber presence sensor detects the presence of lumber in the L2 drive. EMITTER RECEIVER Figure 5 2.5 Operator Console Major functions of the machine are controlled from the keyboard, mouse, and flat panel or touchscreen monitor (optional) in the Operator's Console. Figure 6 2.6 Getting Data to the Saw 2.6.1 General Cutting information must be in the format of TRS files. TRS v3.0 files are required to cut bevels on the HB model saw. H model saws can be operated using TRS v2.0 files as they are not equipped to cut bevels. All major truss engineering software can develop these files automatically. Contact the supplier for details. Alpine can supply the file specification if necessary. 2.6.2 Network An Ethernet adapter card is provided with the computer inside the console. The saw can be connected to any network using Cat 5 Ethernet cable. Alpine will not provide the equipment to connect the saw to a network connection by any other means (fiber-optic, wireless, etc.) Except for its distance from the server, the saw computer is just like most other computers on the network. Distance can be an issue, Alpine recommends that the network cable installed and connected by a network professional. If TRS files are being sent to the ALS 4.0 over a network connection, it is mandatory that the saw computer be able to write to the TRS files on the network. This is how completed cuts are recorded. However, the saw will require certain network rights. If this is a problem for a network administrator, have them contact Alpine Equipment Customer service for more information.
