5.9 Gutter cleaning function
For a swimming pool with a overflow gutter it is necessary that the
gutter is cleaned regularly in accordance with the level of pool
usage. Care must be taken to ensure the chemicals used cannot
enter the swimming pool water circuit, to prevent this, a solenoid
valve is inserted in the drain. This solenoid valve opens during
cleaning of the overflow gutter. As a result chemically contami‐
nated swimming pool water flows away into the drain. A contact to
terminal
[K01] ... [K05] creates a potential-free contact. If the con‐
tact is
[live], the circulation is stopped. The solenoid valve can also
be connected to the Dulcomarin
®
II; to do this the solenoid valve
must be connected to terminal
[P02] ... [P07] (230V). If the sole‐
noid valve is operated with a direct power supply, then the contact
must only be made or broken to stop or start circulation. To ensure
that the last chemical residues are rinsed out, the solenoid valve
closes just 15 seconds after switching on of the circulation.
Digital input and MV active: The switch makes a contact: Circula‐
tion off, metering off and switch-on delayed. The solenoid valve
control and the potential-free contact must be wired together and
activated on the same F module.

Operation using two F modules
The solenoid valve control and the potential-free
contact must be wired together and activated on
the same F module.
5.10 Attractions
Control function and feedback
Control of the attractions and the corresponding
feedback must be carried out by the same F
module. If two F modules are incorporated in a
swimming pool circuit, then the control function
and feedback may not be mixed, rather they must
be carried out by the same F module.
The following attractions can be controlled using the Dulcomarin
