Please Read Carefully Before Operating
The G300 is a Microprocessor Controlled, Water Base Fog and Haze generating system.
The Microprocessor is responsible for the following control elements -
Monitoring the heat exchanger temperature.
Driving the heater within the heat-exchanger in a proportional power mode.
Driving the fluid pump units in a pulse mode, relating fluid flow to temperature
Accepting and manipulating data from the Flow, Duration and Interval controls.
Accepting data from the Smoke Switch.
Accepting data from the 0-10 volt inputs.
Sending and receiving data relating to machine/machine linking.
Monitoring the heater and pump power switching devices.
Monitoring the voltage supply.
Determining the mains frequency.
Determining the main mode of operation and adjusting the required parameters.
Monitoring the 31 step mode adjustment preset for parameter offsets.
Monitoring the display preset to allow one of three display modes.
Sending display information relating to FlowRate, Duration Time, Interval Time,
Ready Status, Heater Status, temperature ( if selected) and mode step (if selected).
Water Base Fog Technology
1
Microprocessor Control
Water Base Fog technology is achieved by pumping a Glycol/Water mixture through a
Heat exchanger. The heat exchanger has been heated to the point where at the fog fluid
mixture will vaporize.
The fluids own vaporization forces the hot mixture out of the output nozzle where,
when it mixes with the ambient air, it forms an opaque aerosol (fog). The fog is made up
of tiny droplets of glycol that form around the small particles in the air. The suspended
droplets reflect the light, which is why fog will take on the colour of the light
illuminating it.

Technical Specifications:
1) The G300 must only be connected to a mains supply capable of sustaining at
least 18 Amps, and be adequately Grounded. The supply should be clean and free
of interference.
2) The Power to the G300 should be controlled by the illuminated Mains Power
switch located on the rear panel.
3) Shortly after switching ON, the digital display on the remote panel will
show a 50H or 60H. This is an automatic line frequency check which allows highly
accurate timing features.
4) The Display unit will now start flashing HAZE. This is a default setting. If
Regular Haze fluid is to be used, then the machine should be allowed to continue
without interruption. If the Hi-Power G300 mode of operation is required where
fog fluid will be used, then at this time of display flashing, the button marked
G300 MODE should be kept depressed. The display will change to read G300, until
such time as this mode is recorded, and the machine continues in its start up proce-
dure. The button can then be released. For those machines equipped with a G300
MODE keyswitch please refer to key card for proper keyswitch position.
Should Haze mode be selected when the machine has been operating in
the G300 mode, then it is possible that time will be required to allow the machine
to adjust to the Haze characteristics.
This will be indicated by a flashing C code in the Heat-Flash window of the
remote control.
Operating Procedure
4
Note:
5) The Remote Display will now enter its standard phase. This indicates the Heating
power, the Flow rate setting, and the Ready status.
At this stage the flow rate may be adjusted freely between minimum and maximum
settings. (Upon entering a ready to operate phase the maximum allowable flow rate will
be automatically adjusted based on the energy available. )
6) The Timer controls are of an auto-display option, and will display immediately upon
being adjusted, or if set to any position apart from the Interval being Off will display
approximately every 10 seconds.
The Interval control ( time between repeating fog issues ), allows the following
selection:
OFF - No timer or time display
1-SH - Single issues upon Fog activation
00:10' - Timer selection in 10 second steps
05:00' - to 5 Minutes, then 30 second steps
20:00' - to 20 Minutes.
The Duration control ( time of actual fog issue ) allows the following selection:
00.02' - Timer selection in 2 second steps
00.30' - to 30 Seconds then 30 second steps
08.00' - to 8 Minutes.
Note that when the automatic display of the timer settings occurs, the Interval time
will have a central colon (:) whereas the Duration time will have a central point (.) dis-
played.
) As the machine heats up to its operating temperature, if the flow setting has been
set to maximum, there will be a point when this will readjust to a much lower value. It is
at this point that the machine has reached its lowest ready point. A flashing H or G
will appear in the Ready Flash window, indicating that the machine is now ready at its
minimum level. The machine can in fact be operated at this point, or further time allowed
for maximum issue capabilities. If the machine is allowed further time, then the Flow rate
will be seen to increase in its allowable maximum setting until position 31 is reached.

At this time, or shortly afterwards, the Heat Flash indicator bars on the Remote
handset will reduce from 3 bars to 2, and then 1 and finally no bars, as the heater
switches off.
When settled, the Heat Flash indicator will indicate the power being used in maintaining
the working temperature. Since proportional control is used, this will vary upon the oper-
ating environment.
8) The machine may now be operated fully as desired with due attention to all pre-
vailing safety regulations.
FLUID REPLACEMENT
Replacing fluid does not require any attention to priming conditions. The G300 uses a
unique system of fluid pumping which allows fluid system replenishment without requir-
ing special settings of flow control.
HAZE FLOW CONTROL
The machine will change the characteristics of the Flow Rate settings when Haze mode
is in effect. This allows very short burst issues up to 5 seconds apart to be selected just by
the Flow Rate control when at its lowest on setting. ( 0 is actually no flow, which can
be useful if only a single channel 0 -10v control is available).
This decreases to every 4,3,2, and 1 seconds, after which point normal flow control com-
mences as the flow rate is increased.
This feature allows instant Hazing to be instigated by employing a high flow setting,
then allowing replenishment of loss by means of a low output, high velocity haze issue.
AUTOMATIC and CONTINUAL FLOW CONTROL
The G300 employs an extremely high accuracy thermal monitoring system. Combining this
with Micro-Processor control and a highly stable Patented Heat Exchanger, allows a self
management system to automatically adjust the flow rate for maximum conditions at any
temperature. This means that regardless of energy availability, a continual flow setting is
automatic. If the initial flow setting is high, then this will be decreased as flow continues,
until such time as a stable situation is attained.

The standard Remote Handset may be removed from the machine, and operated
effectively away from the issue site. The maximum recommended cable length is 30 Me-
tres.(100 Feet).
It is not recommended to plug/unplug the handset while the machine is still pow-
ered up. If this should occur, there is a possibility that the display will produce non read-
able characters if transmission is broken mid stream of a display update.
The rear panel of the machine is fitted with a 4 Pin XLR connector which will allow
the connection of two 0 - 10 volt lines.
One line is of a switching characteristic for the activation of fog, simulating the
Smoke On switch, while the second line is for analog control of the Flow Rate.
Both lines can be used simultaneously for complete control, or either can be used
individually.
In the case of the Flow Rate line being used alone, the Smoke On switch will be
required to be set in the On position, and a definite 0 volt condition available from the
controller to switch the fog output off.
No special selection of rear panel control switches is required for this mode of
operation.
The Pin Assignment for the connector port labeled 0-10 v Control are as follows:
Pin 1 Common
Pin 2 Smoke On 0- 10V
Pin 3 Flow 0- 10 V
Pin 4 (Not used)
Analog 0-10V Control
Remote and External Control Features

0-10V Control Pin Assignments
If it is required for a machine to accept Flow Rate data from an upstream unit, then
the Flow Accept switch on this machine must be active.
If it is required for a machine to accept the Smoke On switch data from an up-
stream unit, then the Smoke Accept switch on this machine must be active.
If it is required to control the next downstream machine with the timer control of
the local machine then the Send Timer switch must be active.
Using these various switching options will allow flexibility in a link up pattern, and
enable individual machine setup without the need to break the linking path.

Linking Switch Setting Options
The two modes of operation that can be performed by the G300 machine are unique in their
operating characteristics. They allow distinctly different fluid types to be used for a wide
range of effects.
As stated repeatedly throughout this operations manual, Hazing type fluid should
not be used in the Hi-Power G300 Fog Mode. Although actual machine damage will not
result, long term performance will suffer as a result.
Changing modes of operation is effected at the point of switch on, and re-selection of
the Hi-Power Fog mode at the time of Fluid replacement.
This facility is available for the purpose of multi-machine control.
The rear panel of the machine is fitted with two 5 Pin XLR connectors for daisy chaining
any number of machines.
Three selector switches above the Remote panel control various available options.
Please note that the protocol of the communication is exclusive to the G300.
Linking cable should be of high quality screened data type.
Communication is dealt with via opto-coupled links, which will isolate ground potential, but
it should be remembered that if the cable is grounded at both ends, then any ground volt-
age difference could convert to high current paths between machines via this screen.
