3.4 Functional description
The unfiltered raw water flows into the filter from the inlet side and then from the inside out
through the filter element and to the pure water outlet.
Thus, foreign particles of a size > 100 µm are retained.
Depending on their size and weight, the foreign particles stick to the filter element or they fall
straight down into the filter funnel.
The backwash process is activated by the GENO-RS-tronic control unit and carried out by
the drive unit on the filter head. The lower suction nozzle is lifted and the drain outlet is open.
During the rotating motion, the brush brushes over the filter surface of the filter element. The
filter element is cleaned.
The impurities are removed by the brush and the suction nozzle sucks them into the drain
outlet.
Product description

BA_TD3-AM001en_014_MXA.docx
3.4.1 Backwash with the GENO-RS-tronic control unit
The GENO-RS-tronic control unit activates time and differential pressure controlled
backwash processes.
Apart from a time interval for the activation of a backwash, an off-period during which no
backwash processes may take place can also be defined.
An actuator opens the backwash water outlet. Initially, in clocked operation and then with
continuous rotation.
The rotation triggers the contact of a microswitch via a cam disc. The microswitch sends
pulses to the control unit. After several pulses, the control unit reverses the direction of
rotation and closes the backwash water outlet.
If the rotary motion is blocked by dirt or wear and tear, the control unit detects this and
responds automatically.
If the control unit cannot resolve the issue independently, a corresponding error message is
displayed (refer to chapter 9).
The control unit features a voltage-free fault signal contact and a voltage-free contact for
remote monitoring. A backwash in progress is signalled via the voltage-free contact.
The control unit monitors the number of backwashes. It provides - sometimes in conjunction
with a timed maintenance interval - information on the remaining number of backwashes in
the current maintenance interval via a bar graph in the display.

5.1.1 Releasing a backwash
With the GENO-RS-tronic, a backwash can be activated in:
1. Automatic release by time interval
● The time interval is adjustable from 1 hour - 99 days.
● The time interval is generally active.
● From an interval period >= 1 day, the start time can be programmed as well.
● An off-period during which no backwash will be released can be activated.
● Automatic backwash before and after the off-period.
2. Automatic activation after a differential pressure is reached
● The differential pressure sensor detects the differential pressure between the raw
water side and the pure water side.
● The differential pressure sensor triggers a backwash when approximately 0.4 bar is
exceeded. Default setting = 0.4 bar; adjustable from 0.16 – 1.6 bar.
● The differential pressure evaluation can be deactivated.
3. Activation by external signal
The backwash can be triggered by means of an external voltage-free contact.
If the contact is closed for more than 1 second, a backwash will be carried out.
Prerequisites for activation via the external contact are:
• No backwash lock is active
• No backwash is active
• No error Er 3 or Er 5 is present
The input can be reprogrammed for an external backwash lock.
4. Manual activation
The backwash can be activated manually by way of the button on the control unit (refer
to chapter 7.2.2). No backwash lock must be active. The basic display (time) must be
indicated.
Behaviour of the backwash filter if there is a power failure
From software version V3.2 on, the time is retained for a maximum of 180 min in the event of
a power failure. The number of the software version can be retrieved via Code level “999”
(refer to chapter 5.5.2).
If a power failure interrupts the backwash process for a maximum of°180°min, it will be
terminated correctly afterwards.

9.3 Manually closing the filter’s suction nozzle
Due to malfunctions, it may be necessary to close the filter’s suction nozzle manually to
avoid unnecessary water leakage.
To do so, you will need the following:
● Open-ended wrench (SW11) or
● Flat-head screwdriver
Proceed as follows:
1. Disconnect the mains plug from the socket.
2. Close the shut-off valves.

7. Loosen the nut.
8. Remove nut and cam disc.
9. Using an open-ended wrench or a screwdriver, turn the wrench flat of the pipe
nozzle to the left until the mechanical stop is reached.
» The suction nozzle is closed manually.
10. Slowly open the shut-off valves.
» The water no longer escapes.
► Mount the drive unit in reverse order.
NOTE: The filter’s suction nozzle has been tightened too much.
● The lower suction nozzle got stuck.
● The drive unit does not provide the torque required to open the suction nozzle.
There is a risk of damage when the unit is put back into operation.
► After manual closing, start a manual backwash.
► Check whether the drive unit properly opens the suction nozzle.
» The water flows from the bottom of the backwash water connection.
