Troubleshooting
E.A.H.S. is not working.
Possible cause(s): no power going to the E.A.H.S.
Possible solution(s): first check that the power toggle switch is “ON”, the red L.E.D. on the
remote pendant should be on. If not verify that the unit is plugged into the correct supply
voltage, then check the fuse and all cables are plugged in.
E.A.H.S. is working, but will not calibrate or track in auto mode.
Possible cause(s): check polarity of welding ground cable passing through the current
sensor.
Possible solution(s): verify if the welding process is electrode positive or negative. If the
process is electro positive (positive welding torch) the welding ground cable passes through
the current sensor with “-ve” symbol on the control box facing the welding power source and
“+ve” facing the work piece. See page 7 for details
The slide does not respond to height adjustment.
Possible cause(s): Limit switch on slide is activated, faulty slide control cable, cable not
connected properly. E.A.H.S. is either tracking at 10 amps (low limit) or 388 amps (high
limit), in both cases the control automatically restricts the slide travel to prevent it going
below 10 amps or above 388amps.
Possible solution(s): Orient the slide so there is sufficient up and down travel during
welding without activating the limit switches. Verify that welding parameters are between 10
and 388 amps.
Note: When the optional 500amp sensor is used the low and high limits are 12 & 485 amps
respectively.
The slide moves in the opposite direction while in Manual mode to what is expected.
Possible cause(s): Depending on the orientation of the linear slide it may be necessary to
flip the position of DS72 switch 3 to correct the problem.
Possible solution(s): flip the position of DS72 switch 3, see page 12 for details.
