This second external height set point could be useful to provide an independent pierce or preheat
height. By using the digital input “Second Height Select”, it is possible to rapidly switch between
normal height and second height while in motion. Another use for the second set height would be
to effectively disable the control unit front panel height set point pot. This would allow for central
control of cutting height and eliminate the possibility of accidental errors due to the unintentional
changing of the control front panel height set point pot.
