# E14 - Safety Mismatch! / E15 - Mismatched Safety!

### Description of error

SPACEGUARD - at least one of the pairs of angle sensors, or slew sensors, is not within the permitted tolerance.

### Solution

Slew the machine over the slew reference point (0º of slew) to reset the safety tooth counting sensor count. If problem persists, use the TEST menu to check the primary and safety slew count, and primary and safety boom angles, and determine which is in error.
