REPLACEMENT OF HY-3 PACK
Mechanically, the inside of
BANDIT
consists out of 2 main components:
-The heat exchanger: this chrome-steel cilinder is filled with hot gassifying channels, which
take care of ‘steaming-up’ the injected
HY-3 fluid to become a dry fog..
- The HY-3 pack with following integrated components: double HY-3 fluid reservoir,
NC
valve, fluid filter, over pressure brake plate and electronics for memory data, temperature
measurement, expulsion registration and communication. The inside of the HY-3 pack
is constantly pressurised to ~ 220 PSI (1500 kPa).
A filled HY-3 pack has a capacity of 1.4 litre HY-3 fluid. With a fog ejection, there is
approximately 28 ml of fluid consumption each second, which means approximately a total of
~ 55 seconds of fog expulsion available.
The MCU on the main PCB communicates continuously with the present HY-3 pack and
calculates, by means of the passed through parameters, how much fluid still is
available in the
HY-3 pack .

P. 41 - Replacement of HY-3 pack
If the level seems to have gone below the
adjusted minimum value (see page 22,
HY-3
pack LED), the unit will request the
replacement of the HY-3 pack . This is shown
in different ways:
-
HY-3 pack front LED blinks.
- The LED bar on the Control Box shows
continuously the measured fluid level.
- If the unit has been asking for replacement
of the HY-3 pack for more than 7 days, this
abnormal situation will be seen as a
technical failure and the [OKout] contacts
will be put in rest for reporting this situation
(
COM
and
NO
open).
Functions of green HY-3 OK LED:
4
Continuously on: everything OK
4
Blinks: The HY-3 pack isn’t accepted,
because e.g..: demo HY-3 pack, an
illegally filled or wrong type
HY-3 fluid
(irritant or coloured fog) . The label has to
mention RF (Regular Fog).
4
The
4
Stays off: there is a fatal communication
problem. Check if the sub-D connector is
clean, try another
HY-3 pack or the unit
has to return to the factory.
Blinks fast (2 Hz): HY-3 pack has to
be replaced, because there isn’t enough
HY-3 fluid left (beneath adjusted minimum
level)
.
