5
The upper limit (or home)
switch was activated while
cutting.
The upper limit switch is
faulty.
Arc Voltage Feedback was
lost while cutting.
Verify that the lifter has adequate range of motion
while cutting. The torch may need to be raised within
the mounting clamp.
Go into the diagnostic screen on the EDGE Pro, HMI,
or control module and check the operation of the
Upper Limit Switch.
Watch the actual arc voltage while doing a manual
cut at fixed height. If the voltage is displayed as 0.00:
• Check arc voltage input to the plasma interface
board.
• Do the test again and check the arc voltage output
from the plasma interface board.
• Check power to the plasma interface PCB as well
as cables to and from the board. If a Hypernet
plasma interface is used, check Hypernet
communications to the board from the control
module display. If Arc Voltage is read at the
EDGE Pro, HMI, or control module, but the
value is low, check the instruction manual for the
plasma system for possible gas problems.
6
During auto operation or
during an IHS test, the
lower limit switch was
activated.
The torch is not positioned
correctly in the torch
holder.
No torch is installed and an
IHS was attempted.
There is no plate under the
torch and the IHS Failed.
The lower limit switch is
faulty.
Verify that the torch is over steel while doing an IHS.
Verify that the torch will make plate contact while
doing an IHS before the lower limit switch is
activated. If not, lower the torch within the torch
mounting bracket.
On the diagnostic screen of the EDGE Pro, HMI, or
control module, check the operation of the Lower
Limit Switch.
