B2x Maximum load power on the output 25W
HV Selection of the supply voltage for inputs / outputs
By means of the jumper, select suitable input and output voltage
JP1 Select the supply voltage between 115VAC and 230VAC
JP2 Select the supply voltage between 24 , 115 , 230V
– exclusively at supply
115VAC or 230VAC
JP3 Select the output voltage
– between AC and DC – exclusively at
JP2 adjusted for 24V .
CAUTION : Set the F08 into the same value of the output voltage, that has been selected via bridges
– to
establish the threshold of short-circuit.
Otherwise, this would result in any malfunction or damage of the micro-controller.
7.3 Startup of the system
Connect the elements strictly according to the diagram, using cables selected with reference to current-carrying
capacity of the receivers.

Switch on the protections in the switchgear A1 .

Check if the F1 fuse in the micro-controller A2 is not damaged.

Apply the supply voltage with the S1 disconnector in the switchgear A1 .

Switch on the system with the S2 switch.

The fan can be safely started with the green button S3.2
– under the condition that the red lamp
ALARM (on
the A1 switchgear door) in not on.

When the green lamp (built in the double button S3 ) is lighting
– this is the information that the fan is in
operation and the filter regeneration system is switched on; {To make sure, the filter regeneration system is
functioning
– after the first device startup, examine the device, check (after the ALARM state emerges) the
communicates emerging on the micro-controller display}. Additionally, after the first start-up, check the
rotation sense of the fan impeller.

To switch off the fan
– press the red button
S3.1 .

The green lamp (build in the button) goes off
– subsequently, proceeds the final filters regeneration – at any
time the fan can be started again.
7.4 Alarms
In the device can appear states of alarms, caused by:

activation of the motor protective switch

interruption of the sensors on the decompression membrane,

alarm from the micro-controller (controlling the function of the electromagnetic valves)
– description in 7.2.2
These alarms are signalised by the red lamp H2 (placed on the door of the switchgear A1 ). When the alarm
occurs, it is important to disconnect the power supply by means of the S1 disconnector. Next, find the fai-
lure/damage, find out its/their reason and remove the malfunction. After the failure is removed correctly,
and the power supply is applied again
– the filtering unit can be operated again.

excessive overheating of the motor windings
–
PTC sensor.
The appliance stops working, but the signalling of activation of the protection
– relay TP – is possible to localise
– after the time passed when the switchgear
A1 opens. Signal from the PTC sensor flows to the resistance relay
PT .
The normal status of the resistance relay PT-1 is signalised by the green diode OK . In case when the motor
windings become overheated, (after the resistance of the PTC sensor exceeds 3,3k

), the relay converts into
status of
“failure”. Subsequently, the contact of the relay will switch, whereby the red diode
PTC is lighted. The
diode OK goes off. When the motor windings cool down, after the resistance of the PTC sensor drops below
1,8k

, the resistance relay returns to normal status.
When in the PT the mode of
“memory” is switched on, (despite the motor windings cool down) – the status of
“failure” will remain until the button DELETE (KASOWANIE) is pressed by the operator.
In the normal status of the resistance relay
PT , when the DELETE (KASOWANIE) button is pressed and hold for
1 second
– switches on the test of the device (for the time when the button is hold). If the test is switched on, while
the device runs in mode “memory”, the status of “failure” will be stored.
In order to return to “normal” state – press the button DELETE (KASOWANIE). The red
PTC diode is blinking,
this indicates the state: the sensor PTC has short-cut or disconnected. This situation occurs when the resistance
at the input (of the PTC sensor) decreases below 40

or increases above 7k

. In these cases, the device gets
into state of “failure”. The memory of the status “failure” is maintained, also after the supply voltage fades.
CAUTION : When the extraction fan is not functioning correctly, please contact the Deliverer.
7.5 Removal of dust
The dust must be emptied systematically, when the waste container is filled up. User has to give instructions to
the operating personnel, that
while disconnection of the waste container from the hopper (by means of the
blocking lever) they must take precautions . In case when the waste container is not sufficiently supported from
