What is a pca? - Precor Exercise & Fitness

Precor Error 30, 31, 32 and 33, Communications Error Probable Cause 1. Bad interconnect cable between upper PCA and lower PCA.
2. Interconnect cable is mistakenly plugged into the CSAFE connector at the upper PCA.
3. Elliptical 5.17 equipped with old software version 1.01 in upper and lower PCA.
4. Upper and lower PCAs have mismatched software.
5. Another component plugged onto the PCA is overloading the +5VDC power supply.
6. Bad lower PCA.
7. Bad upper PCA.
Corrective Action

1. Test unit with a know good interconnect cable or test the interconnect cable for continuity. Replace interconnect cable if necessary.
2. Disconnect the interconnect cable from the CSAFE connector and attach to the proper position on the upper PCA.3.
3. Replace the upper and lower software of the 5.17 elliptical with the most current versions.4.
4. If one of the PCAs is found to have software version 1.01, replace it with the most current software version.
5. Disconnect all components from the upper and lower PCA leaving the data cable connecting between the upper and lower PCAs and the AC power going to the lower PCA. If the unit shows any error other than the error 3x, reconnect components one at a time. Reset power between each newly connected component until the error 3x reappears. Whichever component was last connected when the error 3x reappears, is the cause for the error. Replace the faulty component.
6. Test unit with a known good lower PCA. Replace the lower PCA if necessary.
7. Test unit with a known good upper PCA. Replace the upper PCA if necessary.

Precor Error Code 30 31 32 33

Precor Error 12, Watchdog (Lower PCA) Probable Cause 1. A failure in the lower PCA overloads the low voltage power supply and causes it to drop below the preset level.
2. A fault in the interconnect cable (upper PCA to lower PCA) causing the low voltage power supply of the lower PCA to be too low.
3. A failure in the upper PCA that overloads the lower PCA low voltage power supply causing it to be too low.
Corrective Action

1. If the error message is continually displayed when the unit is powered up, the upper PCA needs replaced.
   External causes may make the error appear intermittently.
   1. If the AC input of the unit dips significantly during power up test sequences, the test could fail causing the error to appear.
   2. A treadmill connected to a non-dedicated AC circuit can experience this error intermittently.
2. Determine if the interconnect cable is the cause by substituting a know good cable in place of the current cable. For test purposes, the substitute cable needs to be connected directly between the upper and lower PCA's, without routing the cable internally.
3. Determine if the upper PCA is the cause by substituting a know good upper PCA for the existing upper PCA.

Description
Errors 30 through 33 all indicate the loss of communications or erratic communications between
the microprocessors in the upper PCA and the lower PCA. The trouble shooting procedures for
all of the are essentially the same. Error 30 is defined as upper PCA not receiving from lower
PCA. Error 31 is defined as faulty data received from lower PCA. Error 32 is defined as lower
PCA not receiving from upper PCA. Error 33 is defined as faulty data received from upper PCA
Possible Causes
1. An upper PCA to lower PCA interconnect cable is bad.
2. The interconnect cable at the upper PCA was mistakenly plugged into the CSAFE connector.
3. A 5.17 EFX equipped with version 1.01 upper and lower software.
4. A 5.17 with mismatched upper and lower software.
5. A defective lower PCA.
6. A defective upper PCA.
Possible Remedies
1. Substitute a know good interconnect cable between the upper and lower PCAs to determine
if the interconnect cable is defective.
2. Remove the interconnect cable from the CSAFE connector and insert it in the correct upper
PCA connector.
3. Replace the 5.17 upper and lower software with the most current software versions.
4. If only one of the upper or lower software is version 1.01, replace the version 1.01 software
with the most current version of software.
5. Substitute a known good lower PCA to determine if the lower PCA is defective.
6. Substitute a known good upper PCA determine if the upper PCAs defective.
PCA =printed circuit assembly. test it and fix it.
