E470 Tokenless Smart Prepayment Meter
4.7 Load limiting
The meter supports a load limiting function which when in operation will
provide the user with only a limited supply.
The meter is enabled to operate in Load Limit mode by configuration and
may operate in conjunction with credit, prepayment or PAYG modes.
When enabled and while the meter is operating in Prepayment mode, load
limiting shall only become active when the present balance falls below zero.
When active the usual switching of supply is overridden by the load limiting
function.
When operating in PAYG mode load limiting shall only become active when
the present balance falls below the PAYG Disconnection value. Supply
disconnection is overridden by the load limiting function.
The meter is configured with a Load limit value that has an operating range
of 0 - 24.00kW
When load limiting is in operation the following display will be alternated
with the normal operating displays:
£
Pence/ kWh
€
L I M I
t i n g o n
When Load limiting is enabled the meter will maintain the contactor in a
closed position while the measured power (kW) is below the Load Limit
value.
When the measured power exceeds the Load Limit value supply will be
disconnected and contactor opened. On disconnection the display will show
the OFF message for [5] seconds, followed by the PUSH BUTTON
message. The supply will then be made available for reconnection.
On pressing the meters push button the contactor will be closed and supply
reconnected. Load is again measured. If part of the load has been
removed and remains under the Load Limit value the supply will remain
connected. If the measured load again exceeds the Load Limit value supply
will again be disconnected.
