1. Control (I/O Node or NM I/F card) 2. Sensor
A - Motor reverses towards sensor C - Motor drives forward until flag leaves sensor
B - Flag enters sensor D - Motor stops
The position of the sensors and vanes are fixed, therefore no adjustment is possible.
Camera Reference Position
The camera reference position is the orientation position for many of the machine processes and
functions, (PCB positioning, stencil alignment, cleaning, Hawkeye, stinger and so on).
The reference point can be set up in the Diagnostics Menu.
As of version 10 the reference point is set in the Calibrations Menu.
With the help of the jog function the camera can be driven to the required position and this can be
saved as the Camera Reference position.
