                                  Error 55 - Brake Home Switch Activated Unexpectedly
          This error is associated with the 5.17 EFX. This error indicates that the home switch was
activated at a time other than the initial start up sequence. The home switch is only used to
initially position the moving arm immediately after the 5.17 has been powered up.
Possible Causes
1. Damaged or shorted home switch wiring.
2. Bad lower PCA.
Possible Remedies
1. Carefully check the home switch wiring for possible shorts or faults to the frame. Replace or
repair the wiring as appropriate.
2. If the lower PCA is applying a constant 12 V.D.C. to the gear motor, replace the lower PCA.
