Error 16 - A.C. Input Voltage Too Low

MCL – Green
ASL – Yellow Solid
Description
The condition that causes error 16 has to persist for 15 seconds before it is logged. The most
common cause of this problem is external power fluctuations due to brownouts, blackouts or
other poor power conditions. This can also be caused by wiring that is too small of a gauge to
handle the current, or if the neutrals are shared between multiple outlets. Less likely but
possible is a worn deck and belt causing high current.
Possible Causes
1. Prolonged brown out/consecutive short blackouts/.other poor power conditions
2. Shared neutral/too small wiring/belt deck need replacement
3. Flipping power switch ON/OFF over and over again
4. Motor controller hardware issue
Possible Remedies-
1 Find out if blackouts/brownouts have occurred recently in that area
2 Check if treadmill was running off of a backup generator or backup power source
3 Ask that an electrician verify wiring
4 Monitor minimum rms line voltage with:
5 Treadmill at banner
6 Treadmill at 6MPH with runner
7 Treadmill at banner, run at 6MPH on a neighboring tread
