Portable Plasma Torch Height Controller Manual (F1620)
Safety notice
z This THC will switch in high electromagnetic，it can hurt me if we get to touch
with high electromagnetic . Do not touch shield cable and wire when power
supply is turning on.
z Packing pieces must be installed in accordance with the provisions and
requirements of step.
z GND must follow THC instruction.
Installation note
z THC first check on electrical safety : Before THC first power,making all port of
wiring connected, then unplug motor cable, in other words, do not connect lifting
motor cable temporarily. Then powering on. (warning: Motor cable must be
unplug before powering on, otherwise, the reason why the lift motor has
been rising (declining) is that may be received collision signal , it can injury
lifting motor)
z Check whether the collision function is normal: After THC power on, check
whether the collision detection function is normal, by observing the collision
indicator light to determine whether the normal. Of the following circumstances:
1)If the collision indicator light is turning on, really need to check whether a
collision, for example, whether proximity switch is divorce, whether torch
retaining cap and steel is touching.
If we only use torch retaining cap to detect collisions, separated from the
protective cap and cutting steel. Because there is no contact with torch retaining
cap and steel, the meaning that the collision have not take place, the collision
indicator light should be take off.
If we only use proximity switch to detect collisions, parameter P13 should
be set to 1, the meaning that allow the use of proximity switch detects a collision
signal. Under normal circumstances, the collision indicator light is turning on
when proximity switch is divorce; the collision indicator light is breaking down
when proximity switch is not divorce. If we use in scene, the collision indicator
light is breaking down when proximity switch is divorce, or the collision
indicator light is turning on when proximity switch is not divorce, it explain that
the description of the received signal and the normal, L09 need to set the value of
the inverse. After parameter is set correctly, proximity switch can accurately
reflect the situation of collision.
If we use proximity switch and torch retaining cap to detect collisions at
