Additional Features
The following sections describe additional features of the UMT-C-KV
transponder.
transponder.
Configuration Monitoring
The UMT-C-KV monitors the Host Meter Configuration register in the kV2c
meter. This register contains the programming information for the meter and is
updated whenever the meter is reprogrammed. The UMT-C-KV reads and stores
this configuration data in registers within its own memory. When the UMT-C-KV
configuration registers are read, the transponder reads the Host Meter
Configuration register and compares the data values. If the values differ, the
transponder sets a flag in the Alarm Indicators register and stores the new value in
its configuration data registers.

OTE
Some features and capabilities of the transponder may not be supported, or
may be only partially supported by some versions of master station software.
Installation With Instrument Transformers
In some applications, the meter may be connected using step-down current
transformers (CT) and/or voltage transformers (VT). In all such cases, the metered
consumption represents energy consumption as seen on the secondary side of the
transformer.

Tamper Detection
Detection of meter removal from the socket is implemented via the availability of
power-down counts in the transponder. Refer to Power Down for additional
information. Both Forward energy and Reverse energy are referenced through
dedicated Meter Map Registers.

The Master Station may choose to mask one or more bits using the Tamper
Indicators Mask Register. This will suppress further tamper indications for the
masked bits until the flag is cleared. The Tamper Indicators Mask Register is
configured at the time of integration.

Reverse Rotation
The transponder monitors for reverse energy flow and sets an error/alarm flag in
the Tamper Indicators register if this condition is detected. Reverse rotation must
be greater than or equal to 255 meter units of Reverse energy before this alarm flag
is set.

No Consumption
When no consumption is detected for 24 hours, the “No Consumption in 24 Hours”
flag in the Tamper Indicators Register is set.
