3.11.3 Electrical connection of push-pull valve (e.g. Besgo)
The device has a powered relay output (230V AC, 50/60 Hz) and enables the switching of small loads. This
enables to connect valve or valve combination from any vendor with AC 230V drive. Built-in circuit breaker
has “LVLØ System” sign on devices front panel. Circuit breaker has active failure monitoring as it powers
vital functions of water treatment processes.
For push-pull valves connection of two wires
to “6 WAY VALVE” terminal is required:

BACKWASH - to L (phase) of the valve coil.

N - to neutral of the valve coil N.
The particular make contact is closed (switched ON) without delay when backwash process is triggered. It
is opened (switched OFF) when changing to different position. Only one output is switched ON and the rest
is turned OFF.
Example: When “Backwash” process is triggered, L1 (1
st
phase) is switched on output “Backwash” of “6
WAY VALVE” connector. After Backwash time, output relay is switched off (power off).
For detailed specification refer to
Connector 23;
connector position details are in section 2.2.2.
3.11.4 Backwash using multi-port valve (6-way)
Multi-port (6-way) valve setup has to be performed via LVLØ mobile application in Service section; select
6-way valve.
Valve installed: <installed/not installed> defines if electric 6-way valve is installed in the pool.
Valve type: <standard 6-way/push-pull 5-way> defines type of valve which has influence on backwash
process (see picture below). Select “standard 6-way” to operate all six position outputs of LVLØ (see
section 3.11.2).
Filter cleanup mode:

OFF – filter cleanup is not scheduled, no automatic cleanup process will be started. Also used when
there is no 6-way valve installed.

2x/week – LVLØ performs automatically cleanup two times per week.

1x/week – LVLØ performs automatically cleanup one time per week.

Custom – cleanup will be started based on custom timer.
Example of connecting push-pull valve like Besgo 5-way valve
