The fault light on our injection tower keeps flashing. I counted it and its 4 flashes. Anyone knows what this means? Been trying to find it online but have had no luck!
The injector fault lights do have some meaning. I have pasted a chart below. Its fairly generic but does cover all models of GC ALS towers that I can think of. In your case this is a plunger error. This can be caused by a syringe that is binding. If you have changed the syringe and still get the error, then the tower needs service as there is a problem with the plunger motor circuitry. I hope this helps.
I have marked you post as assumed answered due to its age, feel free to respond if you have more questions.
