Dionex ICS-3000 system
DP dual pump compartment
Pump shuts down with errors of:
Drive current too large
Excessive drive current
This after running variously for 1-6 hours.
Prior to errors, system running normally, about 1550 psi at about 0.25 mL/min
Per Dionex troubleshooting guide, replaced all tubing. Problem persisted. Rebuilt dual pump including seals and check valves. Problem persists.
Ideas??
