Auto/Manual connects with GND, THC is on Auto Mode. When it’s unconnected, the manual
mode is active.
On Auto mode, if the sensor ring is not connected with THC and THC is under disconnection
protection, the indicator “D” Disconnection would turn on, cutting torch would keep lifting up.
If sensor ring is connected with THC, the cutting torch should stop at a position via adjusting
the Height button (THC finds the Auto Height),
On Auto Mode, the height of cutting torch is under control of Height button. At first
commission, always turn clockwise maximum to get the highest height, then turn anti-
clockwise, the height decreases. If adjusting the height is too low, when cutting torch touches
the workpiece; motor will be on a shocking-state.
THC always drives motor to make sensor ring close to the Balance Position ( the set Auto
Height), and it stops when ring is around the Balance Position, 0.2m lower or higher). The
closer, the more slowly the motor runs.
Auto sensitivity meets the request of THC when sensor ring is 5—20mm away from workpiece.
4.2.2 Commissioning Step
1, Install the THC according to the “4.1 Installation”, offer the enough power supply to THC
(CHC-200F use the AC 24V)
2, When power on, check the
red indicator lights
(“D”
、
“C”) to confirm the connection ok
or not. “D” light is on, means disconnection; please check the HF cable, insulator, elastic
connector and sensor ring are connected well or not. “C” light is on, means collision, it might
be short-circuit occur between the sensor ring to torch or HF cable short-circuit.
