ALS Brake Wired Install Guide 3. Physical Installation Before installing the sensor in its final position, please ensure that: All the necessary configuration parameters have been set (number of channels and order, emissivity, startup delay time). We can perform these for you if you get in touch with us before shipping or using the ‘Notes’... - Page 5 ALS Brake Wired Install Guide We do mounting the sensor such that it avoids direct exposure to significant heat sources (i.e. exhausts). The IR sensor has a horizontal FOV of 110°. As the sensor is placed further away, the maximum width of the brake diameter increases.

Page 9: Configuration
ALS Brake Wired Install Guide Always use twisted paired cable for CAN Low and CAN High wiring as it greatly improves the signal’s tolerance to electrical noise. Also try and keep wiring stubs (cables going from the main CAN bus lines to individual devices) at a minimum. Our sensors come with a 0.5m cable, it’s generally ok to have another 0.5m in addition to that. -

ALS Brake Wired Install Guide can be sent. Please consult Appendix A: ALS Brake Wired CAN Protocol for complete information on the CAN protocol. Typical Configuration Procedure: Ensure the sensor is powered and with correct CAN connectivity to the device you’re using to transmit CAN messages from. -
