BASIC DESCRIPTION
The MDG MAX
APS
and ATMOSPHERE
APS
Series as well as their H.O. / TOURING
APS
Versions
were designed with safety and reliability in mind. They are capable of generating pure
white fog or haze for as long as you want (100% duty cycle). Those generators are also
equipped, as a standard feature, with the Automatic Purging System
TM
(APS
TM
). This
system purges the heating module(s) after the first heating cycle and after every emission
of fog preventing residual build up and clogging.
The MDG MAX
APS
and MAX
APS
H.O. / TOURING
APS
Series are variable output Fog
Generators capable of generating large volumes of very dense fog in a short period of
time. They are one of the quietest units on the market.
The MDG ATMOSPHERE
APS
and ATMOSPHERE
APS
H.O. / TOURING Series are non-stop haze
generators capable of creating the finest and almost invisible mist. They highly
emphasize laser and light beams. They also feature variable output.
At the heart of the MDG Generators is an electronic assembly that keeps the heating
module(s) at a very stable temperature which integrates three 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.
A fourth safety system consists of a pressure relief valve which limits the working pressure
and protects against over-pressure.
The temperature is maintained within a narrow margin (the HEAT yellow LED turn on &
off from time to time to indicate the control of temperature) otherwise, an error
condition will result and the Fog Generator will shut down. When one of the safety
systems is activated, the HEAT yellow LED will start blinking indicating the fail mode.
Shut down the main power switch, wait 3 to 4 minutes and retry the generator. If the
fail mode still appears, unplug your generator and return it to an authorized service
center for verification.
The FOG ON signal (green LED) can be applied to produce fog / haze for as long as the
ready level is reached and all other control parameters are within specifications. When
the “FOG ON” signal is removed, the APS
TM
cycle is automatically initiated to clear the
heating module(s). Never remove the power to a generator while it is producing fog –
See the shut down procedures.
The 100% Duty cycle is continuous with specified line voltage, and will degrade with line
voltage loss. If that is the case, it can be compensated by reducing maximum operating
pressure.
