Primary Load Control Group
The SGM3000 Series meters with load control relay(s) support entry of a primary group
identifier.
A value of zero (0) indicates that the relay is not part of a primary load control group.
The default value is zero (0). The valid range for the primary group identifier is 1 to 255.
Secondary Load Control Group
The SGM3000 Series meters with load control relay(s) support entry of a secondary group
identifier. A value of zero (0) indicates that the relay is not part of a secondary load control
group. The default value is zero (0). The valid range for the secondary group identifier is 1 to
255.
Tertiary Load Control Group
The SGM3000 Series meters with load control relay(s) support entry of a tertiary group
identifier. A value of zero (0) indicates that the relay is not part of a tertiary load control group.
The default value is zero (0). The valid range for the tertiary group identifier is 1 to 255.
Load Control Emergency Override State
The SGM3000 Series meters support setting a load control emergency state via a local
command using MeterMate or remote command via the AMI interface. The meter will support
commands sent to individual or combinations of groups of meters, defined by the primary,
secondary, and tertiary groups. The emergency override message will include the duration of
the emergency period in 15 minute increments from 1 (15 minutes) to 255 (63¾ hours).
The meters will support the message executing immediately to put the meter into the override
state or at a delayed time and date. The emergency override message supports the opening or
closing the load control relay. The SGM3000 Series meters will generate an event log entry
when the load control emergency state is changed. The state change event is classified as a
critical priority event by default. The event will include the new state of the emergency
override. The meter will send a notification message via the AMI signal.
4.8 Load Cycling
The SGM3000 Series meters with load control relay(s) support enabling of load cycling
functionality. Load cycling of the load control relay will be started via a command received
locally using MeterMate or remotely via the AMI interface. Load cycling of the load control
relay can be stopped via a command received locally via MeterMate or remotely via the AMI
interface.
The load cycling functionality will sequentially open and close the relay. Load cycling will
commence after a random delay. If the maximum delay is less than the minimum delay, load
cycling will commence when the cycling command is received; there will be no delay. Once the
random delay has elapsed, the load control relay will cycle between open and closed, starting
at whatever the state of the relay was on when cycling is to start. The relay open and relay
close periods will be defined separately.
