FAIL State
FAIL state mode is initiated if any critical error occurs. In this state, the MDG theONE is off,
awaiting an action from the user, and the LCD is flashing.
When error happens, the menu jumps directly to the Error String in the Status Menu. The last
five (5) critical errors are displayed in the LAST ERR String («STATUSLAST ERR»):
 ERROR = REFILL
This error will occur if the generator is unable to fill the reservoir within a fixed time interval.
This may be due to a leak from the fluid line between the external reservoir and the
generator, or simply that the external reservoir is empty.
 Error = P. LOW
This error will occur if the generator is unable to reach the operating pressure within a fixed
time interval.
This may be due to a leaking gas line (between the gas bottle and the generator), a closed or
empty gas bottles, a siphon (liquid) CO
problem with the pressure transducer.
 Error = P. HIGH
This error will occur if the pressure is too high for a specific regime, while the gas flow inlet is
fully closed.
This may be due to a solenoid valve malfunction (electronic or physical blockage), a problem
with the pressure transducer, the heating module partially clogged or the use of siphon
(liquid) CO bottles.

 Error = HEATER
This error will occur if the temperature of the heating module is not increasing with the
proper thermal ramp.
This is generally due to a heater cartridge problem. Shut down the generator and restart it.
Check the heating process with the value of the Status («STATUSSTATExx% HEAT»). If
the percent is not increasing, the heater cartridges have failed.
Using the generator in 100-130 VAC will solve the problem temporary if only one cartridge
has failed
Please contact an Authorized Service Center if this problem persists.
 Error = T. HIGH
This error will occur if the temperature of the heating module is too high.
This is generally due to an electronic problem. Shut down the generator and restart it.
Please contact an Authorized Service Center if this problem persists.
