GENERAL OVERVIEW
Technology
The PTE-100-C PRO combines state-of-the-art digital technology with the
traditional regulation method based on a variable autotransformer and
transformer.
Analogue and digital electronics convert signals in- and out from the unit in
order to be processed and displayed by an 8-bit microprocessor.
The power section is based mainly on electromechanical components.
The unit’s layout is arranged in modules and the number of moving parts is
kept to a minimum for easy and safe operation.
Power Section Design
Classical, direct regulation and transformers are used to generate and con-
trol the high 1,000-VA power output, as shown in the following diagram:
1. An internal relay connects the main power supply to the variac un-
der no-load conditions.
2. The single-phase variable autotransformer (Variac) regulates the
voltage at the primary winding of the output power transformer.
3. A static switch (Triac) guarantees a clean connection and discon-
nection of the Variac from the power transformer’s input.
4. A toroidal transformer guarantees the insulation of the output from
the main power supply.
5. A current measurement transformer, with one primary winding and
two secondaries with 250:1 and 50:1 respective ratios, is con-

USER’S MANUAL

nected to the ‘zero’ output tap of the power transformer. Measure-
ment range switching is automatic.
Auxiliary Voltage Supply
By means of a transformer with multiple secondary windings, the PTE-100-C
PRO features two independent auxiliary voltage outputs:
•Out 3 is a variable 0-250 VDC stabilized, electronically protected
supply with a dedicated ON/OFF switch, and
•Out 4 is a fixed 110 VAC. This fuse-protected output is permanent-
ly active whenever the equipment is switched on.
Measurement and Control
Analogue input is converted to digital values before it is processed and dis-
played. The following external or internal analogue magnitudes are meas-
ured:
•Voltage.
•Current.
•Phase angle.
•Temperature.
Displayed and/or used values like Impedance or Power are automatically
calculated from these magnitudes by the microcontroller.

PTE-100-C PRO
11
The same micro-controller processes all the user’s control actions like output
on/off, the timer activation, the selection and display of function values, and
the protective alarms.
The PTE-FCN variable voltage channel
This add-on, installed inside the PTE-100-C PRO’s lid, provides an addi-
tional voltage source that is variable in amplitude, frequency and phase
angle. The PTE-FCN module is an efficient, accurate and stable amplifier-
based voltage source that provides a high quality output.
The PTE-FCN must be powered from the built-in fix
ed 110 VAC
auxiliary output of the PTE-100-C PRO only. Use the supplied razor-
type bipolar cord for this purpose. The use of any other source to
power the PTE-FCN
module can permanently damage it and is not
covered by the warranty.
Using the PTE-FCN’s variable voltage output in combination with the variac-
regulated power channel of the PTE-100-C PRO, you can test directional
relays, distance / impedance relays, synchronism and frequency relays,
among many others.
Refer to the “PTE-FCN” chapter at the end of this manual for instructions
how to use the independent variable voltage channel.

DESCRIPTION
All the elements in the front panel of the PTE-100-C PRO are thoroughly
described here. In-depth explanation of their use is given in the Operation
section.
Many buttons, namely those that perform a different function when held
down, effectively actuate when released, rather than when pressed. These
buttons will produce a “secondary function” when pressed until an audible
beep is heard.
We will now describe the PTE-100-C PRO along the following sections:
MAIN AC SUPPLY
POWER OUTPUT SECTION
AUXILIARY VOLTAGE
TIMER SECTION
SPECIAL FUNCTIONS
COMMUNICATIONS
MAIN AC SUPPLY
An AC supply block at the lower left-hand corner of
the front panel groups the power cord plug, a fuse
holder and the main on/off switch. Internal filters
prevent most AC perturbations from leaking into the
unit. The OFF position is indicated by a tiny circle in one of the faces of the
main switch.
Main Protection Fuses
The active (12A, Fast) fuse and a spare fuse
are included in the fuse holder. All the fuses
accessible from the front panel are standard,
5x20 mm cylindrical, and their current rating
and type are clearly printed.

POWER OUTPUT SECTION
This is the right-hand section of the
front panel. It contains the main out-
put control buttons, the regulation
variac, the Display #2, the current
and voltage output taps, the tap selec-
tor, the displayed output selector and
a few associated and alarm LEDs:
Output ON/OFF buttons
These buttons connect and disconnect the main power ouput,
i.e. the current output taps and the Out 1 and Out 2 voltage
taps. A red LED indicates the following output states:
OFF: The output has been intentionally switched off
ON: The output has been intentionally switched on
BLINK: The output has been switched off by the unit. This will
be further explained under the OPERATION section.
Regulation Variac
This knob controls the output level of the current and
voltage power taps. The numerical 0-10 round scale is
provided as a positional reference only. The actual
output level is shown in Display #2 and, at any given
regulator position, its value always depends on the
connected impedance. Regardless of the regulator’s
position, no power will be output when the output control switch is OFF.
Always handle this regulator with care.

OFF

USER’S MANUAL
14
A harmful amount of current could be injected into the connected
l
oad if you accidentally switch the output ON with the variac in a
position other than zero.
Current output taps
At the top of the power output section, four current injection taps are pro-
vided to adapt the
current output
characteristics to
the connected
load, as well as to
facilitate the output
level regulation.
Tap zero is the common reference. If you are testing with currents ranging
from 0 to 50 A AC, for example, connect the load between the common
tap and the tap labeled “50 A / 20 V”. If you are using 4 mm bananas, you
will need the supplied 6-mm to 4-mm plug adapters for the common tap
and the 100 A tap.
Press these adapters all the way down before pulling them up for
removal.
0-250 VAC voltage tap (OUT 1)
Out 1 is located on the left immediately underneath the
variac knob. Output from this tap is measured and
regulated in AC volts. Maximum throughput current is
4A in non-continuous service.
0-350 VDC
Out 2 is located on the right of Out 1. Its output is
measured and regulated in DC volts. Polarity is indi-
cated by the black (negative) and red (positive) plug
colors.
voltage tap (OUT 2)
A standard 19 mm plug can be used with this pair of
connectors. All these taps and connectors comply to
the latest international standards and electrical safety
regulations.

Display #2
All the PTE-100-C PRO output magnitudes are shown on Display #2, lo-
cated above the variac’s knob:
The units in which the various possible readings are represented are labeled
on the right edge ot this LED display:
INDICATORS
UNITS
A Current in Amps.
V Voltage in Volts.
% Percentage of the nominal current.
The following measurements can be read on this display:
•Output current in Amperes.
•AC or DC voltage present in Out 1 or Out 2 power taps and also
in Out 3 auxiliary DC voltage tap (regulated independently).
•Percentage of the ‘nominal’ current value entered in Display #1 by
means of the “%” special function.
The floating decimal point is automatically placed to accommodate the
reading to the working regulation range.
Displaying the used output
Variable output magnitudes are shown in Display #2, used as an ammeter
by default. Since there are several output taps but only one display, you
need to select the tap to be displayed by pressing the corresponding display
assignment buttons:
Press this button to view the voltage present in Out 1 (variable
0-250 VAC).
Press this button to view the voltage present in Out 2 (variable
0-350 VDC).

Press this button to view the voltage present in Out 3 (auxiliary
variable 0-250 VDC). Out 3,
located in the center section of
the PTE-100-C PRO panel, is switched on, regulated and pro-
tected independently from the other outputs.
A green LED above its tap will identify the displayed output. If you want to
lock the Display #2 to Out1, Out2 or Out3, press the corresponding dis-
play selection button and hold it for 5 seconds until you hear a beep. To
return to the normal ammeter function, give a brief press to any of these
buttons.
Current tap selection.
The PTE-100-C PRO cannot detect which of the current taps is
connected the load to. Though the current value shown by Dis-
play #2 is common to the four taps, some special functions, overload pro-
tections and calculations require that the current output tab to which the
load is actually connected is identified to the unit. Press this key to sequen-
tially signal the 100 A, 50 A, 25 A or 5 A tap in use.
Though this will not affect the output current nor the value shown in Display
#2, we strongly recommend you to do it whenever you move your connections
to a different current output.
Power Section Alarms
The PTE-100-C PRO’s power section is protected form over-heating and
from overload. These conditions will automatically switch the power output
off and will be signaled by these two orange-colored 3-mm LEDs:
•I Therm. An internal sensor will protect the unit from overheating. This
alarm automatically disappears when the unit cools down to
normal temperature. Operation can then be resumed.
•I Lim. This protection operates when the upper limit of the selected
current tap, or the limit optionally set with the “Ilim” special
function, whichever is lowest, has been exceeded.
Up to 250 A can be attained from the 100A/10V tap for 3 seconds
before the unit’s thermal protection trips.
Refer to the duty cycle
chart in the CURRENT AND VOLTAGE INJECTION chapter to learn
more on how to get currents higher than 100 A from this tap.

AUXILIARY VOLTAGE
Auxiliary Outputs are intended as general purpose vol-
tage supplies, rather than actual power sources. These
outputs are also galvanically isolated from each other
and from the main power supply.
Out 3: 0-250
Out 3 is located on the center section of the front panel.
Polarity of this d. c. output is color-coded in its 4 mm
connectors: black (negative) and red (positive).
Vdc
This auxiliary output has its own regulation knob and an
ON/OFF button with a red LED that will lit when the
output is active.
Out 3’s Automatic Protections
An orange-color LED will blink and the output will be
suspended while Out 3 is short-circuited. In case of over-
heating, the LED will be lit steadily. Both alarms will be
cleared and the output will be automatically resumed
when conditions return to normal.
Out 4: 110 Vac
Out 4, the fixed 110V AC auxiliary output
located next to the AC supply block, is active
whenever the unit is switched on.
Out 3 and Out 4 are protected by two 5x20
mm, 0.5 A fuses located on the left side of
the AC supply block. To open the fuse holder, press and turn
90º anti-clockwise with a small screwdriver.

Timer control
The following buttons are used to control the PTE-100-C PRO’s timer opera-
tion and various start/stop logics:
Successive presses of this button change the start and stop modes
of the timer. The various options are represented by different
combinations of the START and STOP LEDs on the left side of the
button. Refer to the Timer Start and Stop Modes section below.
Use this button to toggle the displayed time between seconds and
cycles (of the power line’s frequency).
This button returns the timer to zero and re-enables the automatic
power shut off. Injection will not stop automatically upon relay
operation if the timer is not previously reset. Please refer to the
Operation section for a more in-depth description of this feature.
Timer start/stop modes
You can adapt yourself to different timing conditions by setting up the vari-
ous combinations of start and stop events for the PTE-100-C PRO’s timer.
The default combination –first and third LEDs- sets the timer to start when the
current or voltage output are connected and to stop when operation is de-
tected at the monitor’s dry or wet contact inputs. Use the MODE button to
toggle between the available combinations:
