OPTO-READERS AND VANES
The Series 8000 controller uses the LU, DZ and LD lane on the vanes to determine where the
lift stops. Stopping at the floor level occurs when the LU or the LD crosses from the reflective
section of the lane to the non-reflective section of the lane.
The sequence of operation of the LEDs as they enter and leave the floor vanes is as
follows:
APPROACHING TOP TERMINAL LANDING
1. BINARY LEDs enter the binary lanes of the vane first.
2. LU LED enters its lane.
3. DZ LED enters its lane.
4. STROBE LED enters its lane.
5. NLU switch enters its cam.
6. LU LED leaves its lane and the car stops.
APPROACHING INTERMEDIATE LANDING (DOWN DIRECTION)
1. BINARY LEDs enter the binary lanes of the vane first.
2. LD LED enters its lane.
3. DZ LED enters its lane.
4. STROBE LED enters its lane.
5. LD lane leaves its lane and the car stops.
APPROACHING INTERMEDIATE LANDING (UP DIRECTION)
1. BINARY LEDs enter the binary lanes of the vane first.
2. LU LED enters its lane.
3. DZ LED enters its lane.
4. STROBE LED enters its lane.
5. LU LED leaves its lane and the car stops.
APPROACHING BOTTOM TERMINAL LANDING
1. BINARY LEDs enter the binary lanes of the vane first.
2. LD LED enters its lane.
3. DZ LED enters its lane.
4. STROBE LED enters its lane.
5. NLD switch enters its cam.
6. LD LED leaves its lane and the car stops.
