4.4.2 Connection of latch outputs
In installations where very low power consumption
is needed, latch valves are usually used. The latch
solenoid valve, also called from impulses, functions
by hydraulically locking its open or close position,
consuming power only in the moment it changes
position. This allows power to be powered by a battery
only or by a battery and a solar panel. The calculation
is made taking the installation's options and auxiliary
systems into account.
The installer can configure the unit to use latch
solenoid valves in the two or three-wire format and a
12 or 22-volt trip voltage. See the section ‘Function - 4.
Parameters - Installer’.
If installing 3-wire models, a diode box must be incor-
porated that is appropriate to the total number of the
unit’s outputs, to make the connection from the start
and stop common outputs. This is unnecessary in
2-wire models.
One of the two wires is connected to the CR output
common and the other to the corresponding output
between R1 and R27 .
When the solenoid valve acts hydraulically in reverse
of the order given by the unit, this command will
be reversed by entering ‘Function - 4. Parameters -
Installer - 5. Various’.
