SYMPTOMS
- Error: "Plunger Homing Fault (1)" (1 = Accumulator Actuator)
- Error: "Plunger Homing Fault (0)" (0 = Primary Actuator)
ENVIRONMENT
- Alliance HPLC system
- 2695 Separations Module
CAUSE
- The solvent delivery system failed to detect the home position during initial movement of the actuators (torpedoes)
- Salt buildup in system
FIX or WORKAROUND
