MDG ATMe - Shut Down Procedure; FAIL State; Error Codes and Causes

ATMe, Haze Generator
User Guide, Rev: C/e, March 2023 15 / 33
Shut down procedure
Never shut down the MDG ATMe while making Haze.
Power off the generator observing the following sequence:
• Turn off the haze emission,
• Wait 60 seconds for the APS
TM
cycle to complete,
• Switch the generator «UNIT OFF» mode («CONTROL
UNITOFF»),
• Power off the MDG ATMe, by switching off the “MAIN POWER SWITCH”.
Switching directly the generator in «UNIT OFF» mode will yield the same result as above. Wait for all the
cycles to complete before powering off the generator.
In Timer Mode, switching «TIMER ENABLED» to OFF will force the PURGE if the generator is still
producing some Haze. Wait for the end of APS
TM
cycle before powering off the generator.
FAIL State
FAIL state mode is initiated if any critical error occurs.
In this state, the MDG ATMe is off, awaiting an action from the user.
A critical error is always displayed in the Status Menu («STATUSERROR»), as well as the five (5) last
critical errors («STATUSLAST ERR»),
• ERROR = HEATER LAST ERR CODE = 6
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(s) 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.
• ERROR = P. LOW LAST ERR CODE = 7
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
bottle, the set pressure of the regulator below 50-60 psi (3.5-4.1 bar, or 350-410 kPa), a ball valve closed
on the gas line or a problem with the pressure transducer.
With CO
2
bottles, too much output or siphon configuration may also cause the regulator freezes.
• ERROR = P. HIGH LAST ERR CODE = 8
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 cryogenic (liquid) gas.
