What does STOP mean on AF7000 analyser after flow interrupted?
AF7000 Flow Interruption/STOP
Per the manual, the motor has stopped. For instruments with a motor isolation switch, make sure that the switch is ON. If it is, the rotation sensor has failed. The issue can happen with the optical sensor/disc gets caught mid-cycle and unseats itself. Remove the optical switch housing lid to verify that the disc did not get caught/stuck with the sensor. If all fails, contact Technical Support.
