GENERAL DESCRIPTION

The SE230K and SE233K are gas detectors for methane and LPG that
advices with an optical and acoustic signal the presence of gas in the
environment.
The SE230K/SE233K detectors are calibrated to notice existent gas
in the environment up to 10% less from the explosion concentration
L.E.L. (Low Explosion Limit), this threshold can change following the
environmental conditions but it will not be over passed, during the first
4 years of use of the 15% L.E.L., after that period the instrument have
to be put out of order or resend to Tecnocontrol S.r.l. for a complete
substitution of the device.
With that aim, the package is provided with a printed label on were is
indicated the correct working period (4 years from installing date); this
printed label have to be filled from the installer on the frontal panel of
the detector during the installation.

LIMINOUS AND ACOUSTIC SIGNALISATIONS

These gas detectors are provided, on the front panel, by three lumi-
nous signalisations:
-GREEN LED (ON): indicates that the instruments is powered.
-YELLOW LED (FAULT): Indicates that the gas sensor is damaged.
-RED LED (ALARM): Indicates that the gas concentration
measured in the air exceeds the alarm threshold.
In case of damage of the sensor, the gas detector is able to indicate the
wrong function, lightning the yellow led and activating a sound alarm
with two seconds' of intermittence. In case of alarm the detector light-
ning the red led and after 20 seconds the buzzer emits a sound alarm
and the relay activates.

LIGHTING DELAYS

The catalytic sensor in the SE230K/SE233K, need to be heated for
about one minute of working in a correct way and for that reason,when
the detector is lighted on the green led it will lighten to indicate that
the sensor is in the heating phase. During this time, all the detection
functions will be inhibited.

OPERATING PROBLEMS

If, after about five minutes after turning on the detector, all three LEDs
blink, this indicates a sensor problem. In this case the sensor must be
replaced.

INSTALLATION
Attention: the installation and the out of service of the instrument
must be done by skilled personnel only. The installation of gas and
the possible stopping device must be in according to the national and
in force prescriptions law.

DETECTOR POSITIONING

The instrument has to be installed:
- the detectors SE230KM and SE233KM for methane at a maxi-
mum distance of 30 cm from the ceiling; the detectors SE230KG and
SE233KG for LPG at a maximum distance of 30 cm from the floor.
- they should be fixed at a distance comprises from 1 meter and 4
meters by the gas device (kitchen, boiler room, etc..).
- possible in every room in which there is a gas device and in resi-
dences with more than one floor, at least one detector for each floor.
Methane Detector
The instrument does not have to be installed:
- directly over the sink or on the gas device.
- in small rooms where alcohol can be utilised, ammonia and spray
bottles of gas or other substances with flying solvents.
- in low ventilated environments.
- near to walls or hindrance that can stop the gas flow to the detector,
or near to exhausters or fans that can divert the air flow.
- in environment in which the temperature can arrive over 40°C or
under –10°C
-in the environment with a lot of humidity or vapours.

INSTALLATION PROCEDURES

by using an screwdriver unscrew on the right hand side the instru-
ment and uncover it. (Fig.1).
Fig.1
Positioning in the correct way the base, on the board mounting 3-
moules boxes directly in the wall by using screws that are provided in
the box. For installing the dowels drilling the wall with a 5 mm drill.

ELECTRICAL CONNECTION

POWER SUPPLY
Attention: The electrical connection has to be carried out by spe-
cialized technical staff. The detectors are power supplied 230Vac
50/60Hz through connecting terminal one and two, or 12Vdc by con-
necting terminal 3 (+) and 4 (-) (Fig.2). It has to be provided with an
device, to be disowned from the detector and the feeding net, with min-
imun 3 mm contact distance in accordance wit has written in the "Euro-
pean Standard EN 60335-1".
