Speed Sensor - Schwinn A.C. Classic Service Manual

Power Sensor (cont.)
Problem: Displayed power is not accurate.
Solution:
1. Perform a full-up calibration. Follow the full-up calibration procedure in the owner's manual.
2. Perform a 0g calibration. Follow the 0g calibration procedure in the owner's manual.
3. If the above 2 solutions do not fix the problem, replace the power sensor. Please take note that upon power sensor replacement the console and
speed sensor will need to be re-paired to the new power sensor.
Problem: Repeated failed pairing with speed sensor.
Solution:
1. Attempt to pair with a different speed sensor to rule out a bad speed sensor.
2. If the above solution does not fix the problem, replace the power sensor. Please take note that upon power sensor replacement the console and
speed sensor will need to be re-paired to the new power sensor.
Problem: Rapid power sensor battery drainage.
Solution:
1. Inspect the rubber gasket between the power sensor and brake carriage for pinch points; exposed battery contacts will cause the battery to
short directly to the brake.
2. The speed sensor may be stuck in an on state; the power sensor will stay active as long as the speed sensor is active hence reducing battery life
significantly.
3. If the above 2 solutions do not fix the problem, replace the power sensor. Please take note that upon power sensor replacement the console and
speed sensor will need to be re-paired to the new power sensor.

Speed Sensor

Problem: RPM does not show up on the console.
Solution:
1. The speed sensor may not be installed correctly. Adjust the sensor such that the flywheel magnet passes <5mm across the speed sensor.
2. The speed sensor may not be properly paired with the console. Follow the pairing procedure described in the owners manual.
3. The coin cell battery may be installed backwards. Install the battery in the correct orientation.
4. The battery is dead; replace the battery with a new battery. Under no circumstances should used batteries be used as a replacement; this will
alter the accuracy of the speed sensor battery monitoring.
5. If the above 4 solutions do not fix the problem replace the speed sensor. Please take note that upon speed sensor replacement the console and
power sensor (if bike is power enabled) will need to be re-paired to the new speed sensor.
Problem: Speed Sensor will not pair correctly to the Console/Power Sensor
Solution:
1. The toggle switch may be switched to the cadence setting. Ensure that the toggle switch is in the speed position and re-pair.
2. The battery is dead; replace the battery with a new battery. Under no circumstances should used batteries be used as a replacement; this will
alter the accuracy of the speed sensor battery monitoring.
3. If the above 2 solutions do not fix the problem replace the speed sensor. Please take note that upon speed sensor replacement the console and
power sensor (if bike is power enabled) will need to be re-paired to the new speed sensor.
