arc voltage mode, there is no decimal point position; unit: V. The first one is
described as follows:
H: the upper limit value. When the height is larger than this value, it is the
high alarm. The cutting torch can only move down and cannot move up.
L: lower limit value. When the height is lower than this value, it is the low
alarm. The cutting torch can only move up and cannot move down.
A: the set value of height; in the automatic mode, this value is used as the
given value to adjust height automatically.
E: Dead zone value (see 7.1).
D: Speed regulating zone value (see 7.1).
C: selection of detector mode (see 7.1).
b: No board falling parameter value (see 7.1)
8. Troubleshooting
For the common faults, inspection methods and corrective measures see Table 8-1.
