Communications Error Troubleshooting

Errors 30 through 33 all indicate the loss of communications or erratic communications between the Upper PCAUpper printed circuit assembly; generally refers to the console. "UPCAUpper PCA board" and the Lower PCALower printed circuit assembly; generally this refers to the lower board. On treadmills, this is the motor controller unit (MCU), and on self-powered units, it is the main board in the lower section. "LPCALower printed circuit assembly; generally this refers to the lower board. On treadmills, this is the motor controller unit (MCU), and on self-powered units, it is the main board in the lower section.".

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 overloaded or shorted +3.3 Vdc or +5 Vdc on the lower PCAPrinted circuit assembly, generally referred to as either an upper PCA or lower PCA., which can be caused by an 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 CSAFECommunication Specification for Fitness Equipment protocol. port on the upper PCA.

Communications error codes: 30 through 33.

RELATED ERROR CODE	DESCRIPTION
30	Error 30 is defined as upper PCA is active, the lower PCA is not communicating
31	Error 31 is defined as faulty data received from lower PCA (extremely rare)
32	Error 32 is defined as lower PCA is active, the upper PCA is not communicating
33	Error 33 is defined as faulty data received from upper PCA (extremely rare)

Troubleshooting Procedure

Review the machine Error Log or CPATouchscreen console Control Processing Assembly. Event Log and note any possible issue related error codes. Then use the Error Code and Troubleshooting Guide to learn about these error codes and procedures to troubleshoot and repair the issue, see Error Code Troubleshooting Guide.
