2. Connections

• terminals L - N: alimentazione 230 V~ ±10% 50-60 Hz
• morsetti 6 - 7: collegamento elettrovalvola VIMAR 16590 o elet-
trovalvola a riarmo manuale NO 12 V d.c. 13 W con energia
di eccitazione non superiore a 0,4 Joule previa rimozione della
resistenza di carico
• terminals 3 - 4 - 5: output relay with change-over contact for
connection of extra alarm signals and for solenoid valves which
differ from the one indicated above (terminals 3-4 if normally
closed; terminals 4-5 if normally open)
All the solenoid valves must be of the manually resettable
type.
If the solenoid valve or the load resistor connected to the terminals
6 and 7 are not of the above indicated type, the yellow LED
the detector will be flashes during normal operation to signal the
lack of connection; this, however, does not impair the performance
of the equipment.
It is possible to connect up more than one detector in the same
building (different rooms), controlling one single solenoid valve.
In this case, the voltage supply of each detector must be
connected up to terminals L and N, respecting polarisation
(L with L; N with N) and the outputs for the solenoid valve
of each detector must be parallel connected, respecting the
numbers on the terminals (6 with 6; 7 with 7).
In this way, a gas leak in any of the rooms will cause the gas
supply to be interrupted, closing the solenoid valve, while the opti-
cal/acoustic warning on the detector responsible for the electronic
switch-off pulse will indicate the room where the gas leak has
taken place (see example figure 4).
