PI(Pitch angle): The ACU displays ‘PI:000.0’ on the LCD. It is calculated pitch angle
of vessel by PCU

of vessel by PCU
YA(Yaw angle): The ACU displays ‘YA:000.0’ on the LCD. It is calculated yaw angle
of vessel by PCU
HALT: If the antenna experiences the same control error twice within 3 minutes, the
PCU isn’t supplying the torque to all motors to protect the antenna. In this case,
the ACU will display ‘HALT’ on the LCD. The antenna continues in ‘halt’ mode until
the ACU power has been reset.
