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

DFR Code = 200
DC Link Bus Under Voltage / 10 Blinks
Possible Causes:
(1) Low AC voltage from wall.
(2) Low AC voltage from EMI filter.
(3) Faulty MCB.
Solution:
__ G1_______
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.
__ G2_______
Replace EMI Filter
__ G3_______
Replace MCB
