Precor Error 15, 16 - A.C. Input Voltage Too High and Too Low

Error 15 - A.C. Input Voltage Too High

Description:
This error monitors the A.C input voltage. If the A.C. input momentarily reaches the upper limit, an error 15 will be logged. The upper acceptable input voltage limit is 132 V.A.C. on 120 V.A.C systems or 264 V.A.C. on 240 V.A.C. systems.

Possible Causes:
1. A.C. input voltage incorrect.
2. A.C. input voltage transients. Transients can be caused by lightning strikes or by other pieces of equipment sharing the treadmill’s A.C power.

Possible Remedies.
1. The A.C. feed into the building’s circuit breaker panel is incorrect or connected to the wrong transformer tap.
2. Verify that the A.C. grounding is good at the treadmill’s A.C. outlet. Verify that the treadmill is operating on a dedicated and isolated 20 amp circuit.

 

Error 16 - A.C. Input Voltage Too Low

Description:
This error monitors the A.C input voltage. If the A.C. input momentarily reaches the lower limit, an error 16 will be logged. The lower acceptable input voltage limit is 90 V.A.C. on 120 V.A.C systems or 180 V.A.C. on 240 V.A.C. systems

Possible Causes:
1. A.C input voltage incorrect.
2. Treadmill is operating on undersized A.C. wiring and/or is drawing high current.
3. Treadmill is operating on a non-dedicated circuit.

Possible Remedies:
1. The A.C. feed into the building’s circuit breaker panel is incorrect or connected to the wrong transformer tap
2. Voltage drop across the A.C input wiring is a product of the length of the wire run and the amount of current being demanded by the treadmill. The longer the run and the higher the current the larger the wire must be. The A.C wiring must be sized to handle 20 amps of current over the loop length of the A.C. wiring.
3. Verify that the treadmill is operating on a dedicated and isolated 20 amp circuit.
