  • Page 28 AVX-7000 - Discharging operations 1. When the OPEN key or the ACC is turned “ON”(or detach grille installing ), (2 sec. after) the position motor will be activated under the high speed mode. 2. When the longitudinal position sensing switch (PUSH SW)/(LIFT SW) turns H - L, the position motor will be stopped and, at the same time, the angle motor will be activated at high speed.
  • Page 29 AVX-7000 - Angle adjustment 1. For example, from the initial position (about 90°), when the UP key is pressed, the position motor will be activated at high speed for the time during the UP key is being pressed and held. When the UP key has been released, or when a second has passed after the hard-stopper is activated, the system will go under the braking mode.
  • Page 30 AVX-7000 - Precautions 1. The angular position will be kept updated while the angle adjusting key is being pressed and held and the last angle will be memorized. 2. When the angular potential does not change toward the expected direction, the system deems it a functional failure to stop the movement at the position.
