Adjusting Limit Switches
If a machine suddenly stops in mid cycle, check the limit switches. A worn limit
switch arm or a misadjusted limit switch is more than likely the cause. (Another
potential cause is faulty photo eyes – for details.)
Depending on the model of limit switch on your machine, the
pre-travel
(amount
of movement from the limit switch arm’s resting position to the position at which
the switch actuates – with a “click”) is either 5 or 20 degrees. The DL-NCB has
five limit switches that have 5 degrees of pre-travel (3 on the X axis and 2 on the Y
axis), and two switches that have 20 degrees of pre-travel (on the Cutter head).
If the arm is moved to the full extent of its travel and you do not hear the limit switch “click”, the switch
needs to be adjusted. Use the set screw on the limit switch arm and adjust the arm to activate at the
desired degree of rotation (see illustrations
below).
Examples of Limit Switches:
