CONNECTION OF THE ELECTRIC VALVE AND
REMOTE SENSORS
The
Beta
SE330K and SE333K control units each have two terminals (5-
6) active when closed, for connecting the following remote detectors (Fig. 3):
for METHANE gas: model SE195KM or model SE396KM.
for LPG gas: model SE195KG or model SE306KG.
If the remote sensors are not connected to terminals 5 and 6, these must
not be modified, and therefore kept disconnected at all times.
Do not forget that the electric valve must be installed on the gas pipe
outside the room to be controlled as it cannot protect against leaks upstream.
The
Beta
SE330/SE333 +
Beta
SE330/SE333 configuration is IMQ
certified.
The other configurations,
Beta
SE330/SE333 + SE195 K and
Beta
SE330/
SE333 + SE396K are not IMQ certified.
ATTENTION:
If there is a temporary loss of power during operation with
positive logic, the N.C. valve closes automatically and will need to be reset
manually when power is restored.
NEGATIVE LOGIC (SE330K):
in this case, the coil of the relay is
kept deactivated (Fig. 6).
It is perfect for N.O. (
normally open
) electric valves (Fig. 7) or N.C.
(
normally closed
) electric valves (Fig. 8).
In the event of an alarm, contacts 8 and 9 remain closed until the
alarm stops.

The
Beta
SE396K detector is not IMQ certified but complies fully with
standard IEC UNI EN 50194.
POSITIVE LOGIC – NEGATIVE LOGIC
The
Beta
SE330K and SE333K gas detector can control an electric valve
using two different logics:
1 – POSITIVE LOGIC (SE333K)
2 – NEGATIVE LOGIC (SE330K)
The
J2 JUMPER
allows you to select the one required.
N.B. The J2 JUMPER is set by default to NEGATIVE LOGIC (SE330K).
N.O. manual

POSITIVE LOGIC (SE333K):
in this case, the coil of the relay is
always live (Fig. 4) to ensure the
inherent safety
of the relay.
It is perfect for N.C. (normally closed) electric valves (Fig. 5).
In the event of an alarm, contacts 7 and 8 remain closed until the
alarm stops.
