4. Main functions
4.1. On-off
valve
With reference to the standards of the series UNI/TS 11291, RSE implements in particular the following services:
UNI/TS 11291-1 4.3.4 Service: Supply management
UNI/TS 11291-6 6 Flow on/off
The gas flow on/off valve is located within the body of the meter into the inlet connection and is not accessible without causing
permanent damage to the meter itself.
The purpose of the valve is to intercept the gas flow towards the user exclusively for the commercial purposes.
In no way or condition,
the valve has to be considered and used as a useful device to assure safety conditions in the user's plant in case of possible
or patent gas leakages.
The valve is specifically designed to assure its performance and functioning for at least 15 years and it is able to provide the control
microprocessor with the actual status of the valve (closed/open) and with information about its correct operation.
The valve can be closed:
Due to a remote control sent via wireless communication channel (e.g.: from the SAC Remote Management Center);
When changing the battery is not authorized;
Due to a break-in attempted beyond the threshold;
When there is no communication for a configurable time;
When the residual battery power is below the critical level;
In case of failure of the Gdm system.
The previously closed valve, can be opened
only locally
by activating the keyboard according to a special procedure (see chapter
4.1.1)
The opening of the previously closed valve must be authorized
in advance
by the SAC - Control Center.
It is possible to display the status of the valve in the related SV menu (see chapter 6 and chapter 7.1.18).
To reactivate a previously closed valve, RSE must have first of all received the "authorization for opening" from the Control Center.
