Safety Covers/Guards
All safety guards must be in place before operating the press. This includes all sheet metal and Lexan panels
around the machine (see Figure 4).
Figure 4
Emergency Machine Off (EMO) / ESTOP
The Emergency Machine-Off (EMO) circuit controller monitors the safety interlocks (see interlock information
below) and the computer to decide if it is safe to allow motor power and movement. When the EMO circuit is
de-energized, the motor servo controller is disabled, and power is cut off from the motor.
With all of the safety interlocks correctly set, the EMO circuit will energize when signaled by the computer. An
interruption by any interlock will de-energize the EMO circuit.
NOTE
: Resetting an interlock will not
automatically re-energize the EMO circuit.
Emergency Stop Interlocks
The Emergency Stop switches are mounted on the lower left and lower right front corners of the press. Though
they are clearly visible, an operator should purposely note their position and understand their operation in case
of an emergency. Pressing either switch de-energizes the EMO circuit and motion is halted. When pressed, the
switch latches in the pressed state and must be turned to be released.
Light Curtain Interlock
The Light Curtain is a secondary operator safety device. When the light curtain senses an obstruction, the EMO
circuit is de-energized, and motion is halted. The interlock automatically resets when it is clear of obstructions
(though the EMO circuit will remain de-energized.)
Pneumatic System
The pneumatic system is provided for the optional air bearing table that allows floating a PCB support fixture for
ease of positioning beneath the Press head. On the CMP, the pneumatic system also provides air to the air
bearing that floats the head for side to side adjustment. There are no special precautions required for
pneumatic system considerations.
