USING THE MACHINE ELECTROFOG
6.2.b Safety device
The machine is fitted with a safety device ( 1 ) (thermostat
for temperature control, connected to the safety relay
KS ), which is activated in the event of faults.
If an excessive temperature is detected, the device
injects water into the tube ( 2 ) to allow rapid cooling.
It is, therefore, essential that, before each treatment, the
water tank ( 3 ) is always completely full of water; there is
a light on the control panel that, when lit, indicates a low
level of water in the tank ( 3 ).
If the water level in the tank remains low, the machine
cannot be started.
ATTENTION
If you intend to use the machine with a temperature
below 0°C, the water in the tank (3) must be replaced
with methylene chloride to avoid freezing.
DANGER
In the event of a power failure or when the main
switch is used as an emergency stop, the safety
system cannot be started. In this case, the
temperature of the device continues to rise and
can, therefore, generate a fire risk.
It is, therefore, MANDATORY to remove the fogging
pipe (2) from the storage room (4) and monitor
the machine until all the elements of the machine
have cooled down.
AUTOMATIC operation is only allowed with a heater
temperature below 650°C; exceeding this temperature
causes the KS relay to be disconnected and, therefore,
the following are stopped:
• the aerosol product suction pump;
• the heater.
In addition, by disconnecting the KS relay, the blue
indicator light of the RESET button on the control panel
lights up.
DANGER
When the temperature of 650°C is exceeded and
the KS relay is disconnected, the following are not
disconnected:
• the TF power supply (400VAC/24VDC) and all
its downstream components;
• the fan.
ATTENTION
After the intervention of an electrical protection
device, or after a ground fault, or after a fault or
malfunction of the machine, however, it is not
possible to restart it automatically when the
normal conditions are restored, unless voluntarily
restarted (by pressing the RESET button) on
the control panel. Any unexpected start-ups (or
restarts) may be excluded by an isolator switch
on the main electrical panel.
