6.4 Clip installation and adjustment of
the APS system
The clips serve the following functions:
• Guide clip:
- Guides/aligns the code tape along the optical axis of
the APS sensor.
- Prevents the code tape from swinging and twisting.
• Position indicator clip:
- Guides/aligns the code tape along the optical axis of
the APS sensor.
- Prevents the code tape from swinging and twisting.
Depending on the downstream processing unit, the
APS sensor can detect the exact position of the position
indicator clip. The downstream processing unit can use
this information
- to detect doors and floors.
- to compensate for building shrinkage.
6.4.1 Installation of the guide clip
1. Whenever handling the code tape, use cut protection
gloves to prevent potential injury.
2. Insert the code tape into the clip guide rails (Figure
44).

3. Turn the clip by 90º.
4. Fix the clip using appropriate screws and ring washer.

6.4.2 Installation of the position indicator
clip
1. For all operations with the code tape use cut
protection gloves to prevent of cutting.
2. Insert code tape in the clip guide rails (Figure 45).

90º clockwise
3. Turn the clip by 90º.
4. Fix the clip using appropriate screws and ring washer.
5. The recommended distance between the clips
depends on the nominal speed of the elevator and
other factors such as airflow in the elevator shaft. A
typical value is 3 - 5 m. It is important that enough
clips are used to prevent the code tape from twisting.
