When the alarm occurs
– on the controller display
(on the
Master Screen
)
appears a message
AL24V
. Alarm of the
24VAC
supply fade is read out within a 10 seconds of delay.
When the
AL24V
alarm appears, the
H3
lamp starts blinking and the acoustic signal (buzzer)
activates. The alarm has to be confirmed with the
S2
(
STOP
) button.
The alarm effects in blockage of the system, until the alarm disappears.
After the alarm reason
has vanished,
press the
S2
(
STOP
) one more time
– this will switch off the lamp

High efficiency and filter cleaning executed by the automatic filter regeneration system (repea-
ted
air impulses)
provide long durability and reliable function
of the
filter cartridges and limits its
maintenance to the minimum.
The impurities are separated (by the pneumatic impulses) from the filter surface. Subsequently
they fall through the discharge hopper chamber into the waste container. The waste container
must be emptied systematically. Before emptying the hopper chamber should be tapped to re-
move the remaining dust, impurities from the hopper surface.
Periodically, the filter regeneration system must be dewatered. Open the drainage valve of the
compressed air and release the condensate water from the installation. Close the dewatering
valve when exclusively clean and dry air is discharging from the installation. The construction
of the extraction fan and motor guarantees the
work of the unit
without the routine everyday te-
chnical maintenance.
In case when defective function
of the device is noticed,
submit it to technical revision (see Sec-
ction 8).
Any repair activity and technical revisions are admissible to be carried
out exclusively after the device is disconnected from the power supply system.

9. Maintenance
The construction of the
device
does not require any everyday technical supervision, except for
periodical verification
of the mechanical and electrical connections,
especially the connection
with the local grounding profile.
From time to time, after the completed work,
clean the chambers
of
electromagnetic
valves
from
the accumulated dust.
Every time, before emptying the waste container, it is important to “tap”
the discharge hopper chamber (to strike all the pollutants dawn into the waste container).
