TROUBLESHOOTING

COMMON INSTALLATION ERRORS

NEGATIVE SCALING FOR STROKE

Problem:

  Negative value was entered in stroke 

scaling. 

Solution:

  The analog input module cannot see 

negative voltages. The wiring must have the 
positive (+) terminal on the analog input above 
the negative (‑) terminal. 

The 

eDART

 determines the stroke direction 

using the Screw Run signal. It will invert the 
signal automatically if necessary to get a positive 
volume and stroke curves, and to analyze flow 
of material. 

If there is no machine sequence module input 
for Screw Run positive numbers for full scale 
must still be used; set the screw direction 
correctly in “Sequence Settings”. The stroke 
signal should ascend positively while the 
material is being injected into the mold; the 
zero of the screw (screw bottom) must also be 
set.

FALSE CYCLE START ON PRESS POWER‑UP

Problem:

  Job on 

eDART

 is started before 

machine is powered on.

Solution:

  Always power the 

eDART

 on after the 

machine is powered on.

Analog signals tend have a spike or a sudden 
“lurch” from zero to a specific position voltage. 
Often the 

eDART

 will interpret the forward jump 

of the stroke signal as the cycle start. Sumitomo 
machines are particularly prone to this false 
trigger problem because a calibration cycle is 
performed at each power‑up. 

INCORRECT INJECTION PRESSURE 

SCALING

Problem:

  Injection pressure scaling is incorrect.

Solution:  

The 

eDART

 system and Lynx sensors 

eliminate the need for the manual scaling steps 
if injection pressure (for electric machines) 
comes from either a nozzle pressure sensor or 
an electrical signal from the machine. However, 
if signals from another source are used, then 
scaling must be manual input in the 

eDART

.

The electrical signal for pressure is usually 
0–10 V ,with a “low” voltage (not always 
zero) being no pressure and a “high” voltage 
(not always 10 V) being the highest pressure. 
Compare the machines reported hold pressure 
to the 

eDART‑

reported

 

pressure to determine 

whether a scaling adjustment is necessary.
