Me8, Fog Generator
Basic description
The Me8 Fog Generator was designed with safety and reliability in mind. It is capable of
generating pure white, non-toxic fog for as long as you have fluid (100% duty cycle). This
generator is also equipped, as a standard feature, with the Automatic Purging System™
(APS™). This system purges the heating module after the first heating cycle and after every
emission of fog preventing residual build up and clogging.
The Me8 is a variable output Fog Generator capable of generating large volumes of very dense
fog in a short period of time. It is one of the quietest units on the market.
At the heart of the MDG Me8 is an electronic assembly that keeps the heat exchanger at a very
stable temperature, with three different types of fail-safe systems. Those three types of electronic
fail-safe systems are designed to protect against over and under-heating conditions and against
component failure. When an overheating condition is detected, or if the internal temperature of
the generator reaches 60°C (140°F), a safety circuit is triggered. This circuit removes the power
to the heating elements, preventing hazardous conditions. When an under-heating condition
occurs, the generator will stop producing fog until the temperature of the heating module is
back within parameters.
A fourth safety system consists of a pressure relief valve which limits the working pressure and
protects against over-pressure.
The temperature of the heat exchanger is maintained within a narrow margin. If an error occurs
(see FAIL State), the Fog Generator will automatically shut down. When one of the safety
systems is activated, the Fail state will be displayed on the LCD, in the Status Menu. Check the
FAIL State and Troubleshooting paragraphs for diagnostics, then shut down the main power
switch, wait 30 seconds, and then switch the generator back on. If the failure persists, send your
generator back to an authorized service center for verification.
When « Fog On » mode is activated (DMX or Control Menu), the MDG Me8 Generator will
produce fog for as long as the ready level is reached (temperature) and all other control
parameters are within specifications.
When « Fog On » mode is deactivated, the APS™ cycle is automatically initiated to clear the
heating module. Never remove the power to a generator while it is producing fog – See the Shut
down procedure.
WARNING
 When not in use ALWAYS switch off the power switch located on the back
panel, and disconnect both gas and AC line.
 Never install above people.
 This Me8 Fog Generator must be installed in an upright position on a stable and
leveled surface.
 Use in a well-ventilated area.
 Do not operate at less than 2 meters (6.5 ft.) from people.

OPERATING INSTRUCTIONS
The MDG Me8 Fog Generator can be controlled either locally, with the keyboard, via DMX (see
DMX control and RDM Control). This paragraph focuses on local control.
Starting Procedures
When powering up the generator, the control program configures the Input/Output, and loads
the configuration parameters saved in the EEPROM memory.
At this point, the MDG Me8 switches to stand-by mode, and most of the electronic controls are
off.
When the generator is manually switched to «UNIT ON» mode («CONTROLUNITON»), the
program starts the heating cycle («STATUSSTATE = % HEAT»), which will last approximately 7
to 8 minutes.
When the temperature reaches READY level («STATUSSTATE = READY»), the Automatic
Purging System™ (APS™) will be initiated («STATUSSTATE = PURGING»).
After the first purging cycle is completed (approx. time 60 sec.) the generator is ready to produce
fog.
Fog Production
When the generator is manually switched to «FOG ON» mode («CONTROLFOGON»), the
Me8 will start producing fog.
The amount of the fog emission can be controlled
(«CONTROLPRESSUREXX») from 2 psi to 40 psi.
by
adjusting
the
pressure
The MDG Me8 will produce fog as long as the control parameters are within specifications, and
the fog fluid reservoir filled.
If a critical problem occurs, the program shuts down automatically the fog generator, and
displays an error message in the State Menu (see Fail State) and the LCD will flash.
When the generator is manually switched to «FOG OFF» mode («CONTROLFOGOFF»), the
Me8 will stop producing haze and initiate the automatic purging cycle.
WARNING
Never power off a generator while it is producing fog – See the shut down
procedure.
User Guide, Rev: A/a
14 / 30
Me8, Fog Generator
Shut down procedure
Never shut down the MDG Me8 while making Fog.
Power off the generator observing the following sequence:
 Turn off the fog emission,
 Wait 120 seconds for the APSTM cycle to complete,
 Switch the generator «UNIT OFF» mode («CONTROLUNITOFF»),
 Power off the MDG Me8, by switching off the “MAIN POWER SWITCH”.
Switching directly the generator in «UNIT OFF» mode by DMX/RDM will yield the same result as
above. Wait for all the cycles to complete before powering off the generator.
FAIL State
FAIL state mode is initiated if any critical error occurs.
In this state, the MDG Me8 is off, awaiting an action from the user.
A critical message 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
MASTER & SLAVE
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 or a AC Voltage too low. 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
MASTER
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.
 ERROR = P. HIGH
LAST ERR CODE = 8
MASTER
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, the set pressure of the
regulator above 60 psi (4.1 bar, or 410 kPa) or the use of cryogenic (liquid) gas.
User Guide, Rev: A/a
15 / 30
Me8, Fog Generator
 ERROR = T. HIGH
LAST ERR CODE = 4
MASTER & SLAVE
This error will occur if the temperature of the heating module is too high.
This is generally due to an electronic problem or a sensor problem. Shut down the generator
and restart it.
 ERROR = T. SAF
LAST ERR CODE = 5
MASTER & SLAVE
This error will occur if abnormal temperature difference between the two sensors of the
heating module is detected.
This is generally due to an electronic or a sensor problem. Shut down the generator and
restart it.
 ERROR = PCB HIGH
LAST ERR CODE = D
MASTER & SLAVE
This error will occur when the internal temperature of the generator is too high.
This may happen if the external temperature is high. Move the generator in the shade or to a
cooler location. Shut down, wait few minutes, and then restart the generator.
 ERROR = WD RST
LAST ERR CODE = E
MASTER & SLAVE
This error will occur if the watchdog (software safety) resets the generator.
This is generally due to software error, an interference or chip problem. Shut down the
generator and restart it.
 ERROR = CONTROL
LAST ERR CODE = F
MASTER & SLAVE
This error will occur if the control board does not receive any answer from the slave board
This is generally due to software error, interference, a wiring problem or a chip problem. Shut
down the generator and restart it.
Please contact an Authorized Service Center if any problem persists.

DMX CONTROL
The MDG Me8 can be controlled via a DMX512-A USITT standard protocol.
WARNING
Activating the «DMX» mode («INTERFACEMODEDMX»), controls the MDG
Me8 only by DMX signal. If the DMX wire is unplugged or DMX signal is lost, the
generator initiates an automatic shutdown procedure.
Activating the «AUTO» mode («INTERFACEMODEAUTO»), controls MDG
Me8 by DMX, only if there is a signal. If the DMX wire is unplugged or DMX signal
is lost, the generator keeps the last DMX values.
WARNING
In «AUTO Mode», DMX commands always take precedence over Local commands.
The MDG Me8 provides a simple way to check if there is DMX signal:
DMX Signal
No DMX Signal
The user can change the DMX Start Address in the Interface Menu (« DMX Add»), and choose any
value between 1 and 510 (512, last DMX channel).
The generator uses three (3) DMX channels:

Channel 1
0 (0%)
 UNIT OFF  128 (50%)

Channel 2
0 (0%) – 255 (100%), FOG OUTPUT (from minimum to maximum)

Channel 3
0 (0%)
 FOG OFF
 128 (50%)
 UNIT ON
 FOG ON
 255 (100%)
 255 (100%)
These channels have the same behaviour that the menus of the local interface (see Operating
instructions paragraph).
User Guide, Rev: A/a

Me8, Fog Generator
BOOTLOADER
The MDG Me8 uses a BootLoader, also called boot manager. This program is a firmware
(software embedded in a hardware device) located into the non-volatile memory of the
microcontroller unit (MCU) that allows in-circuit reprogramming of the device using its USB
communication port.
To upgrade the firmware, you will need:
 a computer running under Windows, with a USB 2.0 connector
 special driver for the USB, included in the package,
 a standard USB 2.0 cable, A to B Male/Male type
Contact the MDG Service to have the last package firmware upgrade for the MDG Me8.
RDM CONTROL
The MDG Me8 can be controlled via a RDM ANSI E1.20 protocol, an intelligent bi-directional
communication utilizing the DMX512 data link.
RDM allows a console or other controlling device to discover and then configure, monitor, and
manage intermediate and end-devices connected through a DMX512 network. RDM provides for
intelligent control of devices on a DMX512 network, which has not been previously available
outside of proprietary networks
RDM Control has the same functionalities than the DMX Control (see DMX Control) with bidirectional functions allowing the user to read or write specific functions.
