Communications Error Troubleshooting - Precor Experience 700 Series Service Manual

Communications Error Troubleshooting

Errors 30 through 33 all indicate the loss of communications or erratic communications
between the Upper PCA
The main reason for a general communication error is a faulty interconnect cable, either it is
not connected securely, or it has become damaged. Error 30 can be caused by an over-
loaded or shorted +3.3 Vdc or +5 Vdc on the lower
external component plugged into the lower PCA. Error 32 is often caused right after service
or installation, when the interconnect cable is unplugged from the upper PCA while the
lower PCA is powered. It is also caused when the cable is plugged into the
the upper PCA.
