Input Power Troubleshooting

The machine requires reliable stable input power for proper operation. Poor input power issues such as low/high line voltage levels, incorrect or unstable frequency, intermittent power, power spikes, etc, can cause machine operating issues. The following error codes are related to poor input power issues:

Related Error Codes

RELATED ERROR CODE	DESCRIPTION
10	Line Frequency Out Of Acceptable Range
11	Low Voltage Watchdog (Upper PCAUpper printed circuit assembly; generally refers to the console.
12	MCMotor controller or motor controller module / 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. Software Watchdog (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.)
14	Fan Fail (Lower PCAPrinted circuit assembly, generally referred to as either an upper PCA or lower PCA.)
15	DCDirect Current: electrical current that only flows in one direction. Bus Over Voltage
16	ACAlternating Current: electric current which periodically reverses direction between positive and negative polarity. Input Voltage Too Low

Troubleshooting Procedure

Review the machine Error Log or CPATouchscreen console Control Processing Assembly. Event Log and note any one of the possible 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.

Input Power Verification

Verify that the facility outlet wiring is an individual branch circuit voltage, the voltage level is within limits, and that the frequency is within limits, see Power Requirements.

Tripped machine or facility circuit breakers

If either the machine or facility power panel circuit breakers trip, see Tripped Circuit Breaker for troubleshooting help.
