Precor Error 16, AC Input Voltage Too Low Probable Cause 1. AC input voltage is incorrect.
2. Treadmill operating on undersized AC wiring and/or is drawing high current.
Corrective Action

1. Verify AC feed into the building's circuit breaker is correct and connected to the proper transformer tap.
2. The AC wiring must be sized to handle 20 amps of current over the loop length of the AC wiring. Voltage drop across the AC input wiring is a result of the length of the wire run multiplied by the amount of current being demanded by the treadmill. The longer the run and the higher the current the large the wire must be.Verify the unit is connected to an isolated and dedicated 20 amp circuit.

Precor Error 16

Precor Error 27, Too Much Drive Motor Current Probable Cause 1. The running belt and/or deck are badly worn.
2. Drive motor is shorted or de-magnetized causing a high power demand.
Corrective Action

1. Check the amp draw using a clamp on AC volt-amp meter during loaded and no load conditions and compare values to a similar treadmill that is known to have a good running belt and deck. Replace the belt and/or deck if necessary. Don't forget, some units have a double sided deck which means it may be flipped over rather than replaced if it has an unused side.
2. Test unit with a known good drive motor. Replace drive motor if necessary.

• Error 05, Key Depressed at Power Up
  

Typically on the Precor Treadmills if there are errors on the unit, you can press and hold the stop button for 3-5 seconds and it will go into the error log. Not sure what model you have.
E-2 is not what normally shows up on the screen. Do you mean Error 2 was displayed? From what I have read on Error 2's it could be a upper PCA issue, or possibly a dip in AC input during the power up sequence.
Treadmills require a dedicated line, meaning it is on its own dedicated circuit on your fuse panel/circuit breaker.
What exactly is the treadmill doing? Is it constantly showing Error 2 on the screen? Call up Precor tech support. They will be able to give you advice, and or get you connected with an authorized Precor factory trained technician who will be able to get you back up and running.

Hi
not to sound funny but are you sure that you have this tread set in the units (mpg/kph) that you require. i have worked in loads of gyms and its a common problem that people think the belt is running to fast because its set in kph and that thinks its in miles eg 9mph = 14.5kph
you can check and change the units in the club setting menu.
hope this helps :)
