Precor Error Code 52 Resistance Brake Current High HW

Mar 19, 2022

Applies to SCL800

Issue Symptoms

Hardware version of Error 50, see 50  .

The LPCA Hardware has detected that the Resistance Brake Current was too High. Too much current is being fed to the Resistance Brake resulting in the holding brake engaging.

Error 52 triggers when the Resistance brake current is continuously greater than 2 Adc for longer than 410 ms. This event would most likely be caused by a faulty or damaged resistance coil, or a faulty or damage LPCA component or circuit.

Error 52 can only be detected during a workout while the stairs are moving and recovers as soon as the stairs stop.

Troubleshooting steps

1. Make sure the resistance brake cable is properly connected to the LPCA.
2. Unplug the eddy current or resistance brake assembly cable connection from the LPCA.
   1. Inspect the eddy current (or resistance) brake coil wires for visual wire damage. Replace brake assembly if damaged.
   2. Use the eddy current brake cable connector to measure the resistance through the eddy brake coil. If infinite resistance (open circuit) or zero resistance (short circuit) replace the eddy current brake assembly.
3. Replace the LPCA.
