Ⅷ、Commissioning.
1. Up/Down connects with GND, motor moves up and down at maximum speed.
Auto/Manual connects with GND, THC is on Auto Mode. When it is open, the
manual mode is active. In this situation, if the detecting loop is not connected
with THC and THC is under circuit-broken protection function, cutting torch
would keep lifting up. If loop is connected with THC, the cutting torch shall stop
at a height via adjusting the Height button.
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. In case over adjusted, cutting torch
touches the workpiece; motor will be on a shocking-state.
The system always drives motor to make detecting loop close to the balance
position (it stops when loop is around the balance position, 0.2m lower or higher).
The closer, the more slowly the motor runs.
Auto sensitivity meets the request of system when loop is 5—20mm away from
workpiece.
2. As the difference of cutting torch, it might be hard to find the balance position
in all range of Height adjusting. In this situation, DO NOT open the control box,
just debug the⊕ of R39 +⊕ at the back of HCB2001,
