TROUBLESHOOTING
COMMON ERRORS
SIGNAL ERRORS
1.
Signal(s) do not appear on module test
lights
Any signals that never appear “on” must be
named “Not Used”, even if wired to the
module. In
eDART version 9.xx software Sensor
Locations tool, assign the Sensor Location as
“Not Used”. In
eDART version 10.xx software
Machine Setup/Inputs, the ID7‑M‑SEQ will
automatically assign itself in the Sequence Signal
(ID7) box; select the “i” to open the Locations
selector, then select “Not Used” for a signal(s).
2.
Signal(s) are unknown
If a signal does go on and off but is unknown,
then name it “Unknown” and review it later
(with the cycle graph or sequence lights
functions).
Signals that have been assigned and have lights
that go on and off at the wrong time must be
corrected. In
eDART version 9.xx software
Sensor Locations tool, select the correct
signal name. If none of the signal names listed
correlate to the signal, then select “Not Used”
(or “Unknown” to review it later).
3.
Injection forward signal
On some machines the injection forward
signal may not perform as specified; the
eDART sequencer can adjust for some of
these abnormalities. For example, if the screw
run signal is available it will reject additional
injection forward on signals until after the screw
stops.
With other problems, such as a half‑second
variation of the start of injection signal from shot
to shot, or signal “bounce” at the beginning that
causes the
eDART to read the injection forward
was on for a quarter of a second.
In
eDART
software version 9.xx, use the
“Sequence Settings” “Injection” page:
•
If the start of the signal is unreliable, select the
“Ignore Injection Forward Sequence Module
Input at Start”. The
eDART will use screw
motion (or injection pressure, if no screw) to
determine the start.
•
If the end of injection is not stable, or does
not go off at the end of injection, select the
“Ignore Injection Forward Sequence Module
Input at End”. The
eDART
will use the falling
pressure (corner or threshold) to determine
where injection ends.
•
If no Screw Run signal is available, then the
“Ignore Injection Forward OFF
→
ON” setting
may need to be adjusted if the injection
forward signal comes on twice. Set the
“ignore” time long enough so that the
eDART
does not detect the second event.
Each of these settings are saved with the
machine; the settings only have to be applied
once on a machine and are saved with the
setup.
