cause this problem.
On split phase motors, a failure of the start capacitor or
start winding may also cause this error. Failure of drive
relays, the encoder, or bad connections between the
interface/control board and the rest of the electronics
may also be causes.

Hardware Limit Hit
This indicates that the device has reached a mechanical
limit. The hardware limits are intended as an emergency
safety limit to prevent mechanical damage and should
not be encountered under normal opera
to be at least 10-15 centimeters or degrees beyond the
software limits of the Model 2090. Once engaged,
hysteresis of the mechanical limit switch assembly will
typically prevent motion in the limit direction until the
device has been moved far enough away from the limit
to allow it to disengage. On some devices this can be as
much as 20-30 cm/degrees.
Most current devices equipped with limit switches have
knobs for adjusting the limits mounted either on the side
of the motor base or in a box mounted under the
turntable. Other devices, such as the Model 2065 LoPro
Turntable, have the limit switches permanently fixed and
the device must be adjusted to run between those limits.
A new limit switch assembly being introduced will use
optical interrupters behind a small removable cover.

Polarization Limits Violation
This error indicates that an attempt was made to ch
the
antenna was outside the software limits for the target
polarization. In order to protect the antenna from
damage, the Model 2090 will prevent the tower from
changing polarization and generate this error condition.
See the section on “Polarization Violation and Limits” in
the “Operation” chapter for more information.
