SF-HC25C3 Height Controller

Initial positioning: the block after receives the start arc (ARC) block driving down
hoisting mechanism, Zero point (Zero) signal is valid, said cutting device has met
the steel plate, the tones to rise block driven lifting gear, rise time for "IHS time",
"IHS time" to finish the initial alignment is complete.
Start arc output: after the completion of the initial positioning output and arc
signal to the plasma power, such as waiting for a time after acquisition of arc
voltage.
Start arc successful feedback: the arc voltage within a certain amount of time
keeping within the normal range is rev arc (perforated) has been successful, the
block signal success (0-OK) to the numerical control system.
Automatic tracking: in success (0-OK) signal was given and the numerical control
system that start arc can be cut to walk successfully, at this time as long as the
numerical control to the block signal automatic (AUTO) to the block, the block
will enter into the state of automatic tracking.
