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 instru-
ment have to be put out of order or re-send to Tecnocontrol S.r.l. for
a complete substitution of the device.
With that aim, the package is provided with a label on were is indi-
cated the correct working period (4 years from installing date); this
label have to be compile from the installer on the frontal panel of the
detector during the installation.
SEGNALAZIONI LUMINOSE E ACUSTICHE
LUMINOUS AND ACOUSTIC SIGNALISATIONS
Questi rivelatori sono dotati, sulla parete frontale, di tre segnalazio-
ni luminose:
These gas detectors are provided, on the front panel, by three lumi-
nous signalisations:
- LED VERDE (ON): Indica che l'apparecchio è alimentato.
- GREEN LED (ON): indicates that the instruments is powered
- LED GIALLO (FAULT): Indica che il sensore gas è guasto
- YELLOW LED (FAULT): Indicates that the gas sensor is
damaged
- LED ROSSO (ALARM): Indica che la concentrazione di
gas misurata nell'aria è superiore alla soglia d'allarme.
- RED LED (ALARM): Indicates that the gas concentration
measured in the air exceeds the alarm threshold
Nel caso il sensore si guasti il rivelatore è in grado di segnalare il mal-
funzionamento attivando la suoneria con un intermittenza di due
secondi, accendendo in modo fisso il led giallo e l’uscita relè.
In caso di allarme, dalla centralina o da remoto, si accende il led rosso
e dopo venti secondi si aziona la suoneria ed il relè.
In case of damage of the sensor, the gas detector is able to indica-
te the wrong function, lightning the yellow led and activating a sound
alarm with two seconds’ of intermittence.
In case of alarm the detector lightning the red led and after 20
seconds the buzzer emits a sound alarm and the relay activates.
