cleared. This is simply a side effect of the other error
condition preventing the Model 2090 from detecting the
motor stopping.
E004 evice Moving In the Wrong Direction
This error indicates that the device has moved too far in
the direction opposite the direction commanded. On
towers, this error can be caused due to an overloaded
cross boom, or a weak brake, where the carrier moves
down under the force of gravity before moving up. For
devices with split-phase motors (towers and light duty
turntables) this error can also be caused by reducing the

that this error will be generated if either the motor or the
