INSTALLATION
The AVM14 Encoder must be installed in accordance with Pepperl-Fuchs instructions and with the
relevant hazardous area installations standards/codes of practices.
WIRING
The AVM14 data interface is based upon RS422 clock and data signals. The PCB4205 Processor
GPIO port is utilized for the data interface and requires a CIRPCB4311 TTL-to-RS422 signal
conversion daughterboard.

The following must performed to commission the absolute slew encoder:
1. Identify and document intended zero-degree heading for the installation. Zero-degree
heading must be in an onboard location for fail-to-safe response.
2. Install and power encoder as per system diagram and instructions.
3. Slew crane to the pre-determined zero degree reference heading.
4. Set Encoder to zero counts by shorting pin 7 to pin 2 for one second inside the junction
box.
5. Select the appropriate RCI-4100 function code to enter number of teeth on slew gear.
6. Use appropriate RCI-4100 function code to enter the number of teeth on the encoder cog.
Once these steps are performed the encoder will read from 0.0 to 359.9 degrees as the crane
slews. Note that the encoder is limited to 2047 rotations in either direction. This will not be an
issue with most installations since the slew gearing ratio may typically be 15:1, thus the crane
would need to slew in one direction only 137 turns before reaching the limit.
