      E20 - Slew left into limit!

      Description of error

      SPACEGUARD - The pilot line pressure sensor monitoring the slew LEFT driver request indicates that the operator is trying to slew LEFT into a slew or wall limit.

      Solution

      If slew LEFT is not being operated, use the TEST menu (External Inputs, Module 9 SLEW, input 7) to check the input from the slew left request for correct operation, check slew LEFT pressure sensor in the slew left pilot line.
