Description
TAS-331DG is a micro controller based power transducer with 1 analog output for
measurement of Watt or var. The transducer holds no mechanical moving parts like
potentiometers and therefore the calibration stability is excellent.
Label
The configured transducer is provided with a label with the following data:
The un-configured transducer is provided with a label with the following data:

Mounting instructions
TAS-331DG is designed for
panel mounting, being
mounted on a 35 mm DIN rail,
or by means of two 4-mm
screws.
Weight: Approx. 0.650 kg
The design of the transducer makes mounting of it close to similar equipment
possible, however make sure there is min. 50 mm between the top and bottom of the
transducer and other equipment.
The DIN rail must always be placed horizontally when several transducers are
mounted on the same rail.
Connection diagram
With voltages above 480V phase-phase.
The secondary side of the current transformer must be connected
to earth. Alternatively a double insulated current transformer can
be used.

It is not necessary to protect the measuring voltage inputs. But it is recommended to
use a 2A fuse for the supply input (terminals 1 and 3).
The transducer is protected against ESD (electrostatic electricity), and further special
protection against this during the mounting of the transducer is not necessary.
The below diagram illustrates how to connect a TAS-331DG in 2W3 configuration with
a TAS-331DG in 2var3 configuration.

Connection/set up
The transducer is equipped with a red LED for indication of wrong phase connection
or errors in the calibration / configuration. This LED is placed under the front plate.
The function of the LED are as follows:
Constant light. The wiring may be wrong. There is not equal power direction on all
phases. There must be signal on all inputs to ensure correct testing and current flow
in all phases. Note this function is only activated in coupling 2W3, 2var3 and 3W3(4),
3var3(4).
Fast pulse 5Hz. The calibration data are corrupted. Contact DEIF.
Slow pulse 1Hz. The configuration data are wrong or corrupted. Make a re-
configuration or contact DEIF. About configuration see special manual.

Opening of the unit
Mounting of the front panel
The front panel is
removed by means of a
screwdriver. The front
panel may be loosened
in the right side first and
is then totally demounted
by moving the screw-
driver towards left.
Press with a screwdriver as
indicated by the arrow and press
the front panel down with your
thumb, simultaneously. It is
recommended that one side of
the front panel snaps into place
before the other.
