BASIC OPERATION

The following instructions explain how to operate the basic functions of the
machine. It is assumed that the machine is being started from cold.

Starting with all the control panel switches OFF, and the display showing
‘OFF’, go through the following sequence.

Set the Standby switch to ON.

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. 20 minutes heat-up time) fog can
be produced.

Fog display shows FOG/Rdy

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. Refer to the Fault Finding section of the handbook for
advice.

Set the Fog switch to ON to produce continuous output of Heavy Fog.

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). Note that the Fog switch overrides the
timer switch.

Fog display shows ton/04,toff/03 etc

Ice display shows Den/nor

Ice display shows Den/nor

COMMISSIONING THE MACHINE

USER
GUIDE

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. Fit the fluid line and cap to the
container.

Check the wiring instructions in the Safety Guidelines section of this
handbook and connect the machine to the power supply.

Set the power switch in the power inlet box to the ON position, and look for
the start-up message on the displays.

Set all the switches on the control panel to OFF and refer to the Basic
Operation section of this handbook for information on how to use the main
functions of the machine. Read the

before using the

machine.

REMOTE CONTROL OPTIONS

The Heavy Fog Glaciator provides the user with 3 ways to implement a
remote control on the machine. The main control panel is fixed and can not
be removed for remote operation.
All the remote interfaces are located on the panel adjacent to the control
panel.
The options are:

.

The interface uses the two XLR 3 connectors marked DMX on the interface
panel, and uses the usual DMX electrical standards (RS 485). The inputs
are protected against overvoltage and an ouput connector is provided to
allow multidrop operation of the link.

.

The remote interface uses an XLR 3 connector to allow a standard JEM
remote to fire the machine.
Full proportional control of the Fog output can be achieved, but the Density
level must be set on the control panel.

.

This connection is an option available to installers who wish to control the
machine using the ouputs from a standard Programable Logic Controller
(PLC). When the interface PCB is fitted, 12/24v DC control signals can be
used to switch the Fog, Standby, Timer and Ice functions. The output levels
and timer settings must be made using the control panel.
