Description
The lift control system has detected
that the lift is moving in the opposite direction of the issued lift command.
Possible
Causes
1. Lift Motor hysteresis.
2. Bad lower PCA
Possible
Remedies
1. This error would typically happen
when the lift was already in motion (typically downward)
when a lift command in the opposite
direction (lift up) was issued. Some motors exhibited a
very long turn around time and the
lift motor would still be moving in the original direction
(downward) while the control system
was attempting to move the lift in the opposite direction.
If the error 45 condition is
persistent, replace the lift motor.
2. This is a very rare condition, if
the lift moves in the opposite direction of the issued lift
command,
replace the lower PCA.
