‘ARMED’ state of relay:
For safety reasons an ‘ARMED’ state is introduced between the relay OFF and ON states. This gives user the
control to reconnect their supply from the meter when it is safe to do so (e.g. appliances are off). When the
meter’s relay is in ‘ARMED’ state, the ‘LC ON 1’ icon will blink on its LCD and an appropriate message will be
displayed which signifies that the meter is ready to reconnect relay and is waiting for the user input.
Closing the relay from the ‘ARMED’ state:
When the relay is in the ‘ARMED’ state, the ‘LC ON 1’ icon will blink on the meter’s LCD followed by the
message ‘PRES LB’ and ‘CONNECT’. On pressing the left push button on the meter it then displays ‘PRES RB’
followed by ‘CONFIRM’. On pressing the right push button within 30 seconds the relay will close reconnecting
the supply otherwise it will stay in the ‘ARMED’ state and the meter’s display will revert back to the previous
display sequence i.e. ‘PRES LB’ followed by ‘CONNECT’.

4.10.2 Connecting/disconnecting relay remotely
In Premier 211, the relay can be in ARMED, ON or OFF state remotely using the authenticated supply
command (i.e. via UTRN) either immediately or on a scheduled date (in 30 minutes’ resolution). The scheduled
date must be within 365
days (compile time configurable) from the current date. The meter will not accept the
supply UTRN for any scheduled date which is more than the configured number of days.
The meter accepts a request for relay disconnection even, if it is already open due to another reason. However,
to close the relay any other reason for disconnection should not exist. For example, if the relay is already open
and a remote command for relay disconnection is sent to the meter, in this case meter shall accept the
command. The relay will only close (by user interaction) after remote reconnection (ARMED) command and
credit update has been received.
