complete list of the different configurations
available for the Smart RTU.
3.2 Default Configuration

3.3 Performance and operation limits
This product has been selected to meet the
specification of your purchase order.
The following data is included as additional
information to help with your installation. This is
typical information and if required, a definitive
statement for your application can be obtained from
Flowserve.
Smart RTU material compatibility is
the responsibility of the end user.
3.3.1 Sensor specifications
Refer to section 1.8 Specifications for available
sensor specifications.
3.3.2 Battery
Power is provided by a user-
replaceable sealed lead acid 12V battery, located
inside the Smart RTU enclosure.
Battery life is dependent upon data transmittal
intervals and charging system operation. Battery
voltage should normally be between 12.0 and
12.8VDC. If it is lower than 11V, the battery will
need to be replaced with the one specified on the
wiring diagram. The battery voltage can be read
using a voltmeter (with the charging system fuse
opened). The battery is then charged by either a
solar panel or an AC power supply (dependent on
specific unit). Typically the battery is expected to
last 5 years, if the charging system is properly
functional.
3.4 VB-103-TAM Optional Accessory
The VB-103-TAM is an optional Take Away
Memory module for the Smart RTU. When
connected to a Smart RTU, it automatically logs
data from all sensors at the preconfigured log
interval. Data from the VB-103-TAM and the log
interval can be reviewed utilizing an IPS Dock
connected to a PC. The VB-103-TAM is set to a
default log interval (how often current data from the
Smart RTU is logged to the VB-103-TAM device) of
5 minutes (300 seconds), unless otherwise
specified. This is independent of the normal
measurement interval of the Smart RTU which
governs how often sensors are read.
The battery logged on the VB-103-TAM
unit represents an internal voltage being supplied
to the RTU board. This battery voltage reading
should normally be around 3.3V and is not directly
representative of the RTU battery-backup voltage
or AC/solar power supply voltage.
The VB-103-TAM has a separate battery
that governs the lifetime of this unit. The expected
life of this battery is 6 years at the default 5 minute
log interval. The battery in the VB-103-TAM is not
replaceable and requires replacing the VB-103-
TAM unit when it is depleted.
The VB-103-TAM also has a finite amount of data
storage available. Dependent on the amount of
data points being measured and the measurement
interval, this storage capacity is defined as listed in
the table below.
