5.9 Meter valve state
The supply valve has three states –
1. On: Valve will be in the opened state, and there will be continuity of supply
2. Off: Valve will be in a closed state, and there will be no supply
3. READY: For safety reasons, a ‘READY’ state is introduced between the supply OFF and ON states. This
gives the user the control to reconnect their supply from the meter when it is safe to do so (e.g.
appliances are off). When the gas valve is in ‘READY’ state, the ‘READY’ icon will illuminate on the LCD,
and an appropriate message will be displayed indicating that the meter is ready to reconnect supply and
is waiting for the user to press the correct key sequence on the meter’s keypad.
Important!
The supply will get disconnected in case of the following conditions:
● No balance
● Excessive gas flow (Inrush flow)- During the valve opening process (When user manually presses ‘A’
followed by ‘B’) if gas flow exceeds the uncontrolled gas flow rate (30 litres/hour), it returns back to
the ‘READY’ state.
● Tamper
Reconnection of the valve will always require manual intervention. Fix the reason for valve
disconnection, then press Key A, followed by Key B.
5.9.1 Opening the valve from the ‘READY ‘state
When the valve is in ‘READY’ state, the ‘READY’ icon will illuminate on the meter’s LCD followed by the
messages ‘PRESS A’ and ‘CONNECT’. Pressing key ‘A’ on the meter displays ‘PRESS B’ followed by ‘CONFIRM’.
Pressing key ‘B’ within 30 seconds of pressing key ‘A’ opens the valve and resumes the supply. Otherwise, it
stays in the ‘READY’ state, and the meter’s display reverts to ‘PRESS A’ followed by and ‘CONNECT’ display
sequence.
