Unattended Operation

1.2 Unattended Operation
Fully enclosed Haas CNC machines are designed to operate unattended; however, your
machining process may not be safe to operate unmonitored.
As it is the shop owner’s responsibility to set up the machine safely and use best practice
machining techniques, it is also the owner’s responsibility to manage the progress of these
methods. You must monitor your machining process to prevent damage, injury, or loss of
life if a hazardous condition occurs.
For example, if there is the risk of fire due to the material machined, then you must install
an appropriate fire suppression system to reduce the risk of harm to personnel, equipment,
and the building. Contact a specialist to install monitoring tools before machines are
allowed to run unattended.
It is especially important to select monitoring equipment that can immediately detect a
problem and perform an appropriate action without human intervention.
1.3 Setup Mode
All Haas CNC machines are equipped with locks on the operator doors and a key switch
on the side of the control pendant to lock and unlock setup mode. Generally, setup mode
status (locked or unlocked) affects how the machine operates when the doors are opened.
Setup mode should be locked out (the keyswitch in the vertical, locked position) at most
times. In locked mode, the enclosure doors are locked closed during CNC program
execution, spindle rotation or axis movement. The doors automatically unlock when the
machine is not in cycle. Many machine functions are unavailable with the door open.
When unlocked, setup mode allows a skilled machinist more access to the machine to set
up jobs. In this mode, machine behavior is dependent on whether the doors are opened or
closed. Opening the doors when the machine is in cycle stops motion and reduces spindle
speed. The machine allows several functions in setup mode with the doors opened, usually
at reduced speed. The following charts summarize the modes and allowed functions.
Machines with software version 100.17.000.1016 or higher have Parameter 2083, Setup
Mode Safety Type, that affects the machine’s Setup mode. When Parameter 2083 is set to
Normal, the machine Setup and Run modes behave as outlined in the table that follows.
When Parameter 2083 is set to Strict, both the Setup and Run modes adhere to the Run
mode behaviors. Contact your local Haas Factory Outlet to set Parameter 2083 to your
desired setting on your machine.
DANGER: Do not attempt to override safety features. Doing so makes the
machine unsafe and voids the warranty.
