P. 21 - Communication status - LEDs - Front LEDs
COMMUNICATION STATUS
The unit gives following visual information to its immediate surroundings:
FRONT
LED
s:
On the
BANDIT
-front
you’ll find 6 LEDs.
Through these LEDs
you can easily see
what mode (status) the
unit is in and if there
are any failures
reported.
Available (OK)
N
If
BANDIT
is not in guard mode:
- This green LED is lit when:
a) there is no internal failure detected
b) the unit is on it’s required temperature (temperature high enough to be operational,
and to perform a fog ejection).
Practically, this means: as long as the green LED is on, the unit is ready.
- This green LED blinks if:
a) no internal failure is detected,
and
b) the unit is warming up. As soon as it gets its required temperature, it will be ready
to perform a fog ejection. If the main power supply is present, the unit needs
approximately 50 minutes (from cold condition) to reach its final regulation
temperature.
If
BANDIT
is in guard mode:
This green LED will be on. This way the unit will never reveal through its front panel
the possibility of not being ready.

One of tasks of the integrated “Power Saver” is to take care that the temperature of
the heat exchanger will not raise higher than necessary to produce the adjusted fog
quantity. The temperature of the heat exchanger for a fog ejection adjustment of for
example 5 seconds, is 30°C lower than for an adjusted fog ejection of 15 seconds.
So if you change the fog ejection volume, automatically you’ll also change the
temperature of the heat exchanger. If there is enough difference between the ‘old and
lower’ ejection period and the ‘new and longer’ one, the green LED will start blinking
to show that the unit has not yet reached its new higher temperature.
During a fog ejection period, the temperature of the heat exchanger decreases.The
longer the fog ejection period, the more the temperature will decrease. If the
temperature decreases so much, that it would endanger the fog quality, the unit first
of all is going to warm-up again before performing a new fog ejection (under-
temperature protection). During this excessive warm-up the green OK LED will blink
to show that the unit isn’t ready yet. As soon the blinking turns into continuous on,
a new fog ejection can be performed.
