After inspection, use this option to review all flagged
blades (up to 999 blades can be flagged per engine).
To select review flags, press the flag button.

been reviewed. Press EXIT to return to the main inspection
menu.

selection. When in stop mode, rotation stops at Blade 1
after 360 degrees of rotation have been achieved. Stop
Mode is on by default.
9.3.2 Torque Limit
Select to determine the torque level at which the engine
will be rotated. If this limit is exceeded, the drive motor
will slip and a SLIP ERROR message will appear.

A slip error has occurred. Increase
torque and acceleration time to fix this
error. Use UP arrow

9.3.3 Acceleration
Select to set the acceleration/deceleration at which the
motor will perform before it reaches next blade.
9.3.4 Toggle Direction
Select to change the direction of the engine between
NORMAL and REVERSE. When in REVERSE mode, the
drive motor will rotate CCW even though the pendant
will still display CW. On engines with space constraints
where mounting to the front of the gearbox is required,
this allows the engine to be turned CW and for the display
to say CW.
