7.3 EXPLANATION
7.3.1 MECHANISM DESCRIPTIONS
- Outline of operation- Electrical conditions
1. The system operates by using the forward/backward1. Motor terminal voltage (position motor for ejection,
driving motor and the angle controlling motor.and angle motor for angling)
2. To detect statuses and positions of operation, theFast mode: VMH = 7.0 V
system detects pulses by the photointerrupter andSlow mode: VML = 6.2 V
counts the pulses constantly.2. Encoder pulse
3. The monitor is temporarily stored when the system isConditions for input to controlling microcomputer
restarted by the Reset button. Then, the system: H = 5 V, L = 0 V
ejects the monitor again and starts up.Error timer (time to judge no more pulse is output)
4. The system adjusts angle of the monitor when the: 1 sec
Adjust Angle key is pressed.
5. The system stores the monitor when the
OPEN/CLOSE key is pressed again or ACC is set to
OFF.
- Ejection
1. The system operates the position motor in Fast mode
when the OPEN/CLOSE key is pressed or ACC is set
to ON.
2. The system stops the position motor and operates
the angle motor in high speed when the Position
Sensing switch (Lift switch) in the forward/backward
direction is set to OFF.
Lift switch OFF.
3. The system stops the angle motor after the angle
12th wave or
encoder pulses are output for 12 waves (Brakethe position
mode). If the previous angle is saved in the memory,saved in the
the system moves the angle motor to that angle.memory.
4. The system operates the position motor at low speed
approximately 1 second after the monitor isComes in contact
positioned at the specified angle. Operation stopsmechanically.
mechanically when the motor withdraws. Then, the
system enters Brake mode by the error timer.
Withdraws slowly.
