Notes: * Note on the µP PCB that resistor R150 and capacitor C78 are connected in series across the contacts. In some cases one lead of
R150 must be cut from the control PC board as the R-C circuit may provide enough current flow to maintain machine motion input to
cutting machine.
** Note on the µP PCB that resistor R155 and capacitor C79 are connected in series across the contacts. In some cases one lead of
R155 must be cut from the control PC board as the R-C circuit may provide enough current flow to maintain machine motion input to
cutting machine.

Signals are AC relays. DC relays are available as an option from Hypertherm by ordering kit: 128404

† WARNING
When installing or servicing the HT4001, AC or DC line voltages may be present on the UP, DOWN and
TRANSFER signals even if the power supply line disconnect switch is OFF. Make certain that all line
disconnect switches relating to the HT4001 system are OFF during installation and when servicing.
