User manual JEM HEAVY FOG GLACIATOR

[. . . ] The Heavy Fog effect is provided by cooling the smoke output from the main heat exchanger until it is at a temperature lower than the ambient in which the machine is operating. Air is added to the smoke, prior to cooling, from the fan mounted in the rear of the machine. This increases the volume of the effect and allows the output to be pushed through ducting. A fluid container with 9. 5L capacity (2. 5US Gal. ) is provided for Heavy Fog fluid. [. . . ] Choose a fluid suitable for the venue and type of effect you want to create. Generally, use the standard B2 fluid, but for longer lasting effects, contact a distributor for advice on using another fluid grade.

Starting with all the control panel switches OFF, and the display showing `OFF', go through the following sequence. Fog display shows FOG/Ht Ice display shows Den/nor Set the output to Fog = 8 Set the Ice switch to ON When the machine is ready (after approx. Fog display shows FOG/Rdy Ice display shows Den/nor If starting the machine for the first time, or after the fluid has been changed, the pump may need to be primed. Do this by setting the Fog output to 15 and firing the machine for 10 seconds, or until fog is produced at the output. If the pumps have not primed after 20 seconds, there may be a problem with the fluid system. Fog display shows FOG/08 Ice display shows Den/nor Set the Timer switch to ON to produce timed output (read the Timer section to see how to configure the timer). Fog display shows ton/04, toff/03 etc Ice display shows Den/nor COMMISSIONING THE MACHINE Unpack the machine and look for any obvious signs of damage. Place the machine on a level surface and fit a container of JEM/Martin approved fluid into the fluid compartment. Check the wiring instructions in the Safety Guidelines section of this handbook and connect the machine to the power supply. To ensure correct operation of the displays, the standby switch should be set to the ON position when using DMX. The machine requires two channels, with the address of the first channel set on the DIP switch. The channels control the FOG and Density settings in the following manner. Channel 1 FOG output level 0 - 32 zero output (dead-band) 33 - 255 proportional output level control Implemented in 20 discrete steps Channel 2 Compressor switching and Density setting 0 - 32 Compressor off 33 - 65 Low (Lo) density 66 - 98 Normal (Nor) density 99 High (Hi) density The system implements true proportional control of the fog output rather than the simple switching functions found on other equipment. The output levels of FOG and FAN are linked during DMX operation via the Density setting. The DMX base address can be set to any channel in the range 1 - 511 using the DIP switches. The channel number must first be decoded into binary format before being set into the switches. ICE: Setting this switch to ON, will start the compressor (displays `St' while starting). If the compressor fails to start within 10 seconds, the display will show `StL' and the compressor will be shut down. This function is independent of the status of the STANDBY switch. THE TIMER The timer system is implemented in software using the machine's main control PCB. As such, the timing is crystal controlled and will be of good accuracy when compared to the usual analogue timers commonly found on fog machines. [. . . ] The software that controls the displays and the other functions of the machine is stored in `Flash' memory on the DMX receiver PCB. As new features become available, this program code can be updated by using the Martin Uploader programming device for the AVR microprocessor. MENU KEY ENTER UP KEY KEY DOWN KEY The message displayed will depend on the operating mode of the machine at the time. However, pressing the menu key at any time will cause the display to go into the edit mode, allowing the operating parameters to be adjusted. After approximately 5 seconds since the last keystroke, the display will leave the edit mode and revert to displaying the current status information. [. . . ]
