NOTES :

MSVO/MSVG : NORMALLY OPEN gas solenoid valve with manual resetting EVO/EV : NORMALLY CLOSED gas solenoid valve with MANUAL RESETTING

A) FAULT : function of the electronic circuit which, in case of critical fault to the sensor or main components, is actuated givingluminous signal (yellow LED) and commands closing of solenoid valve.

B) SELF-DIAGNOSTICS : function of the electronic circuit continuously monitoring correct operation of the entire equipment(including remote sensor); in case of fault, it gives a luminous signal and commands closing ofsolenoid valve.

FUNCTION OF SELF-DIAGNOSTICS SAFETY

The gas leak detectors manufactured by INTERMES (GSA3, CIVIC2, CIVIC6 and CIVR) are provided with electronicSELF-DIAGNOSTICS safety function: an electronic circuit continuously monitoring the entire gas detection system forcorrect operation (central units GSA3, CIVIC2 or CIVIC 6 and remote units URA and CIVR plus electrical connectionsbetween them).

When a fault occurs, the yellow FAULT LED lights up on the remote unit (CIVR or URA), while an acoustic and optical sig-nal is given on the central unit as well as command to close the solenoid valve (EVO and EV).
