Start

Turn the unit power off at the 

switch.

Measure AC voltage at the wall 

outlet.

Was the AC voltage 

within the specs 

listed above? 

The AC voltage should 

be between:

95 to 125vac for a 110v unit

185 to 250vac for a 220v unit  

G1

No

Check AC voltage coming out of 

the EMI filter

Was the AC voltage within

 the specs listed above? 

G2

No

Yes

Engage Maintenance Mode

(0, 2, start simultaneously)

Yes

Engage Motor Test Mode

(Press ‘8’ after engaging 

Maintenance Mode)

Increase the speed to 5 MPH or 

greater.

Measure AC input voltage with a 

load 

Was the voltage

greater than a 5 volt 

deferential?

The input AC voltage should be 

less than a 5 volt deferential from 

the original AC voltage that was 

taken with out a load

G1

G3

No

Yes

(1) Low AC voltage from wall.
(2) Low AC voltage from EMI filter.
(3) Faulty MCB.

Consult with electrician 

to fix AC input rail 

voltage.

Note: The AC rail 

voltage with a load 

should never drop 

greater than a 5 volt 

deferential comparing it 

with no load. There are 

many equations to 

measure for low rail 

voltage.

Example: If you take a 

person that weighs 200 

Lbs at the speed of 5 
MPH and the voltage 

drops greater than a 5 

volt deferential, the wall 

voltage is not adequate 

and can cause 

intermittent 200 DFR 

codes.

Replace EMI Filter

Replace MCB
