SH ORT FO REWORD
Dear T 1000 PLUS user,
I often wondered why the user’s manual is not very much used,
even if it includes valuable information. As me too I am a user of
such manuals, the answer I have given myself is that valuable
information are concealed somewhere in the thick thing, and I do
not have time to waste to find it. So, either the manual is actually
of help, or I ignore it.
This is why I decided to split the T 1000 PLUS manual in three:
specification, with all performance details; application manual,
with instructions about how to use it one its operation is
understood; introductory guide, with the device description and
basic information. The idea is that you may read once the
introductory guide or the specification, while you need to follow
application examples more than once; so, why not to split the
manual in three?
Have a good work with T 1000 PLUS!

INTRODUCT IO N
The single phase relay test set mod. T 1000 PLUS is suited for the
testing and adjustments of the following types of relays; the table

In addition to the above, T 1000 PLUS can test:
. Converters: V; I; φ°; p.f.; W; VAr; f., both 0 to 5 and 4 to 20
mA.
. Energy meters, single phase or three phase.

DOC. MIE92093 Rev. 1.34 Page 7 of 108
The instrument contains three separate generators:
. Main generator, which generates either AC current, AC voltage;
DC voltage;
. Auxiliary a.c voltage generator, that generates an independent,
phase shifting a.c voltage;
. Auxiliary DC voltage generator, that generates the DC voltage
that feeds the relay under test.
All outputs are adjustable and metered at the meantime on the
large, graphic LCD display. With the multi-purpose knob and the
LCD display it is possible to enter the MENU mode that allows
setting many functions, which make T 1000 PLUS a very powerful
testing device, with manual and semi-automatic testing
capabilities, and with the possibility to transfer test results to a
PC via the USB interface. These results can be recorded,
displayed and analyzed by the powerful TDMS software, which
operates with all WINDOWS versions, and allows creating a data
base of all tests in the plant.
The basic T 1000 PLUS function is to generate current and
voltages and to stop generation as the relay trips. Test results are
kept in memory, and can be transferred to a PC at a later time,
along with settings.
The ease of operation has been the first goal of T 1000 PLUS: this
is why the LCD is graphic, and so large. With it, the dialogue in
MENU mode is made easy. Besides, all T 1000 PLUS outputs are
continuously measured, and output values are displayed, with no
extra effort to the operator. Also the show waveform feature can
be of help: any doubt about strange measurements, distortion
and so on can be solved.
This is also why we have added the reduced power feature.
Modern relays have a very low burden. As current output is a low
impedance voltage generator, adjusting low currents and/or
current on low burdens is quite difficult because one has to
operate at the very beginning of the adjustment knob. In this
situation it is possible to connect resistors in series; however, one
must be careful not to exceed the maximum current rating, and
the wiring is more complicated. The solution to this problem is
just to reduce the available power: this is easily performed via

DOC. MIE92093 Rev. 1.34 Page 8 of 108
the multi-function knob. With less power, the maximum voltage is
reduced by a factor of 4.4; the adjustment span on the knob is
increased accordingly.
Additional features are:
. Two meters, current and voltage, with independent inputs, allow
measuring T 1000 PLUS outputs or any other source;
. Two auxiliary contacts, that allow simulating the circuit breaker;
. A set of resistors allows easing output adjustment.
The instrument is housed in a transportable aluminum box, that
is provided with removable cover and handles for ease of
transportation.

1.1 CONNECTION TO THE RELAY AND POWER-ON
At first, be sure that the main control knob (6) is turned (rotated)
to the zero position (complete counter-clockwise). The reason is
that the current generator is actually a high current voltage
generator. If the output is connected to the load (typically low
impedance), as soon as the test is started, a very high current
can circulate in the circuit.
Next connect the mains supply cable to the instrument and then
to the supply. THE SUPPLY VOLTAGE MUST BE THE SAME AS
INDICATED ON THE PLATE.
Power-on T 1000 PLUS: a diagnostic sequence controls:
. Key microprocessor board components;
. Auxiliary supply voltages.
If something is wrong, the operator is alerted by a message.
At the end of it, default selections are active; T 1000 PLUS is in
the OFF state.
Perform the first selections, according to the type of relay to be
tested:
. Main output socket, acting on the selector push-button (57).
. Auxiliary AC voltage: range; type of generation; value. NOTE: to
perform the range selection, the output must be ON, and the
value reduced to the minimum.
. Auxiliary DC voltage: range; value. NOTE: to perform the range
selection, the output must be ON, and the value reduced to the
minimum.
. Start and Stop timer inputs.
Connect the relay to be tested to the output sockets that have
the indication light (LED) on.
The following is the list of protections that avoid damaging T 1000
PLUS in case of errors.

DOC. MIE92093 Rev. 1.34 Page 10 of 108
. Fuse on the mains supply.
. Thermal NTC sensor on the main and auxiliary transformers. In
case of over-temperature, an alarm message is displayed.
. Thermal sensors on the SCR that controls current injection, and
of the internal temperature. In case of over-temperature, an
alarm message is displayed.
1.2 TEST CONTROL
The T 1000 PLUS front panel is explained in next paragraph.
T 1000 PLUS generation is controlled by the two keys < (55) and
> (56).
Settings and menu selections are controlled by the multi-function
knob with switch (22): see next paragraph for menu selections
description. At power-on T 1000 PLUS generation is OFF, as
confirmed by LED (50). The ON selection serves for finding relay
thresholds; selections ON+TIME and OFF+TIME serve to measure
relay timing.
The following flow diagram summarises all available test control
selections.
The performance of T 1000 PLUS in Normal Test mode is the
following.
. OFF: main outputs are not generated; Vac aux is generated,
and it can be either the pre-fault value or the fault value,
