Configuration Management
If RCDC Switch Open and RCDC Switch Close are enabled, the headend will
receive alarms twice - one reported by the NIC when it performs the action, and
another by the meter in its event log. If a technician uses a HandHeld MeterMate to
locally open or close the switch, and logging is disabled, the user at the headend
(and MDMS and CIS) will discover the change by monitoring the value of the
RCD switch position, which is reported daily by the NIC.
If the meter is configured to capture voltage sag events in the meter event log, and
MeterMate is used configure the to a very sensitive setting, and Aclara RF is
co-deployed with TWACS, and an Aclara RF meter shares the same service with a
TWACS meter, it is possible, because the meter is so sensitive, for the meter to
detect TWACS inbound at that location. (This scenario might be possible at a
meter bank for example.) We recommend that such a meter not be configured for
its most sensitive setting. The configuration for the sag duration at this location
should be longer than 10 cycles. The sag severity should be down to 0.8 pu or
something more severe.
Display
When setting up items to display on the meter’s LCD, be careful to note the
Display Label you assign to the measurement. This will help set the context to the
user.
Under the Alternate Mode tab, the following should be included on the alternate
display scroll list:
• Diagnostic Tools
• Network Status Info 1 (Network status information)
• Remote Disconnect
• Switch Status
• Diagnostic Tools
• Network Status Info 2 (Self-test results to the user)
• Network Status Info 3 (NIC operating mode information)
Recommended Endpoint NIC Configurations
The Customer Configuration Worksheet will allow certain network behaviors to
be configured.
The bulk of the data transmitted through the network is the LP data from the meter.
The I-210+c collects all channels at the same rate. However, they can be
transmitted to the headend at a different rate than they are collected. If fresh data is
required, intervals can be reported as soon as they are available by setting the LP
Bubbleup Schedule parameter to the same size as the interval. If network
efficiency is more desirable, you can set the LP Bubbleup Schedule parameter to
be a larger size than the LP interval size, e.g., hourly reporting of 15-minute
interval data. However queueing up too much data can be problematic too. No
