FST error: Pressure drop, no breakaway

Description

Breakaway is not detected, but the pressure is below the Minimum breakaway
pressure

Trouble shooting

This error may be due to:

•

Actuator is stuck

•

Position sensor malfunction

This error can be solved by:

•

Check the actuator and valve

•

Check the position sensor

•

Decreasing the Minimum breakaway pressure
