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.

RECEIVER

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.

2.6 Getting Data to the Saw
2.6.1 General
Cutting information must be in the format of TRS les.
TRS v3.0 les are required to cut bevels on the HB model
saw. H model saws can be operated using TRS v2.0
les as they are not equipped to cut bevels. All major
truss engineering software can develop these les
automatically. Contact the supplier for details. Alpine
can supply the le specication 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 (ber-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 les 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 les 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.
