Page 7: Section 1: Overview
One of the most important parameters in Oxy Torch cutting is consistent torch tip to plate standoff distance. The Hypertherm Sensor OHC uses a capacitive sensor to measure the torch to plate distance. The unit will drive a DC motor on the torch lifter to automatically maintain a user selected torch to plate distance. -

Section 2: Operation Section 2: Operation Operation Modes The two basic modes of operation are “Automatic” and “Manual”. Note: The control unit must be calibrated prior to use. See calibration instructions in this guide. Automatic Operation “Automatic” mode is active whenever the “Manual” input on pin-3 of the 15 pin I/O connector is open. -
Page 14: Error Conditions
Sensor OHC Operation and Set Up Guide Error Conditions Red Error LED Error Indications The red ERROR LED indicates abnormal conditions by flashing an error code. The error code meanings are listed below. 1 Flash - Sensor Shorted Error Indicates that the sensor is in contact with the plate. In Auto Height mode, this will cause a rapid retract until the sensor no longer is in contact with the plate. -

Page 17: Limit Switch
Section 3: Installation and Set Up Limit Switch The lifter upper and lower limit switches are connected to the 9 pin “D” connector. These switches are normally closed switches that open when the limit is reached. The upper limit switch connects between pins 5 &... - Page 18 Sensor OHC Operation and Set Up Guide 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.
