Data Industrial 340 Series User manual

The Data Industrial Series 340 Btu transmitter is an economical, compact device for sub-metering
applications.
The 340 calculates thermal energy by measuring liquid flow in a closed pipe system and measuring
temperature at inlet and outlet points. The 340 requires two 10 kΩthermistors for temperature input.
The flow input may be provided by any Data Industrial sensor and many other pulse or sine wave signal
flow sensors.
The onboard microcontroller and digital circuitry make precise measurements and produce accurate
drift-free outputs. The 340 is programmed using Data Industrial’s Windowsbased software and a Data
IndustrialA301 programming cable. Calibration information for the flow sensor, units of measurement
and output scaling may be downloaded prior to installation or in the field. While the unit is connected to
a PC or laptop computer, real-time flow rate, flow total, both temperature readings, energy rate and
energy total are available.
The Series 340 transmitter features two LED’s to verify input and output signals.
The standard output for the Series 340 is an isolated solid state switch closure that is user programmed
for units of energy or flow. The output pulse width is adjustable from 50 mS to 5 sec.
The Series 340 Btu transmitter operates onAC or DC power supplies ranging from 12 to 24 volts.
The compact cast epoxy body measures 3.65”(93mm) x 2.95”(75mm) and can be easily mounted on
panels, DIN rails or enclosures.

INSTALLATION
Mechanical installation
The series 340 transmitter may be surface mounted
onto a panel, attached to DIN rails using adapter clips
or wall mounted using two optional enclosures.
Location
Although the 340 device is encapsulated, all wiring
connections are made to exposed terminals. The unit
should be protected from weather and moisture in
accordance with electrical codes and standard trade
practices.
In any mounting arrangement, the primary concerns
are ease of wiring and attachment of the
programming cable.
The unit generates very little heat so no consideration
need be given to cooling or ventilation.
Surface Mount Installation
The 340 may be mounted to the surface of any panel using double
sided adhesive tape or by attaching fasteners through the holes in
the mounting flanges of the unit.
Din rail Mounting
Optional clips snap onto the mounting flanges allowing the 340 to be
attached to DIN 15, 32, 35 mm DIN rail systems.
Wall Mounting
Optional metal and plastic enclosures are available to mount
the 340 to a wall when no other enclosure is used. The
enclosure is first attached to the wall using fasteners through
its mounting holes.
After wiring, the transmitter may be attached to the enclosure
with the terminal headers facing in using the slots in the
mounting flanges. As an alternate mounting arrangement, the
340 may be fastened to the box cover using double-sided
adhesive tape.

Temperature Sensor Installation
The location of the temperature sensors with regard to the flow
sensor is important to the accuracy of the energy calculation.
Temperature sensor T1 must be located closest to the flow
sensor. Adistance of 5 pipe diameters will give the greatest
accuracy.Always install the temperature sensor downstream
of the flow sensor.
Electrical Installation
All connections to the 340 are made to screw terminals on
removable headers.
Power Supply Wiring
The Series 340 requires 12-24 Volts AC or DC to
operate. The power connections are made to the
ORANGE header. The connections are labeled beside
the header. Observe the polarity shown on the label.
If a Data Industrial plug in type power supply
(A-1026 or A-503) is used connect the black/white
striped wire to the terminal marked positive (+) and the
black wire to the terminal marked negative (-).
Note:
Included with every Series 340 is a 340IK kit
containing a screw, lock washer and nut to connect
the Series 340 to Earth Ground. Connect the Earth
Ground Lug of the Series 340 to a solid Earth
Ground with as short a wire as possible. This will help prevent electrical interference from
affecting the Series 340’s normal operation.
Sensor Wiring
All flow sensor types connect to the four terminal
header labeled “Sensor Input”.
200 Series and M Series
Connect the Red wire to Sensor signal (+), Black
wire to Sensor signal (-) and the Bare wire to
Shield.
SDI Series
Connect the Plus (+) terminal of the sensor to
Sensor signal (+) on the transmitter and the Minus
(-) terminal of the sensor to Sensor signal (-) on
the transmitter. Connect the shield terminal of the
sensor to the shield terminal of the transmitter.
Other Flow Sensors
The Sensor Input Power Out terminal supplies
nominal 12VDC excitation voltage for 3 wire sensors. Connect sensor signal + and sensor signal -
wires to transmitter terminals.

Temperature Element Wiring
The Data Industrial thermistors are not polarity sensitive.
Connect thermistor closest to the flow sensor to Series 340
terminal block marked TEMP 1 and the other thermistor
wires to Series 340 terminal marked TEMP 2.
Pulse Output Wiring
The Series 340 has solid state switch output rated for a
maximum sinking current of 100 mA @ 36 VDC. In most
cases the pulse out (+) terminal of the 340 will connect to
the Input pulse (+) and the pulse out (-) terminal to the Input
pulse (-) of the receiving device. These terminals are located
on a separate two terminal removable header on the 340
labeled “Output”. Observe the electrical polarity of the
output.
Communications cable wiring
Field calibration requires a Data IndustrialA340 Programming kit (consisting of a custom cable and
software) and a PC running Windows®9x, ME, NT or 2000. In order to calibrate, the Series 340 must
be connected to power, and the A301 cable must be connected to the 340 Comm port connector and an
available 9-pin COM port on a computer.
Note:
The Data Industrial A301 Cable will work
with all 300 Series products. However
the older version of the cable (A300)
does not have sufficient bandwidth to
work with the Series 340 Transmitters.
Data Industrial provides free programming
software updates via the Internet for all of
Series 300 devices. Go to
www.dataindustrial.com for these updates.

Data Industrial flow sensor “K” and “offset” information is printed in the flow sensor owners manual,
and also available on our website. Calibration constants for other sensors must be supplied by the
manufacturer.
Note #2
Typically the Temperature measured by T1 will be greater than T2 in a heating application or T1 will
be less than T2 in a cooling application. The Selection of one of these choices will determine if
energy calculations are made for heating only (T1>T2), cooling only (T1<T2), or both (absolute)
Note #3
The filter coefficient screen allows adjustment of the flow and energy filters.Ascale of 0-10 is used
