after completing the interrogation on the system, below are our findings:
the failure of the encoder in the anticoagulant (ac) pump motor causing the motor to go into run away mode giving a f20 error code was the only reason for the failure.As precautions the ac, plasma pump motors, pump driver board, hall effects switch, r.A.M batteries were replaced and full pm was performed to insure proper performance.Unit ran for one hour with all four motors at 200rpms no errors occurred.
