MENTOR 12
“All in One” System for electromechanical, electronic,
and numerical protec tion relay t esting
INNOVATION
The new Mentor 12 universal platform revolutionizes the traditional relay testing concepts. With more
than 25 years in designing and developing test equipment, EuroSMC has launched a product which
exceeds the expectations of the most demanding professionals in this field.
The Mentor 12 has everything you need to test relays of any type, including the routine procedures and
results saved in memory by the user for later repetition and reference. No external computer is
required, except for existing and upcoming remote control applications that are not part of the builtin software. Also incorporated is an auxiliary voltage supply source to energize the relay under test when
required.
Based on the success obtained from the PTE family of relay testing products, EuroSMC has equipped
the Mentor 12 with a fast, powerful yet simple manual control interface that allows the expert user to
verify the response of any relay in seconds. For the more complex or repetitive jobs, however, a full set
of pre-defined, fully configurable test tools will assist the operator for an efficient, safe and error-free
testing.
Your Mentor 12 will never become obsolete because all its functional elements are completely
programmable. You can upgrade its software over the internet and install plug-and-play hardware options
with no external assistance.
Ultra-compact output amplifiers, energy saving system, self-regulated ventilation, automatic auto-resetting
protections with dynamic status reports, safety indicators, etc., we have charged the Mentor 12 with
state-of-the-art features to keep it in perfect shape and ready at all times.

MENTOR 12
Low Level Outputs, USB and Ethernet connections
POWER
A state-of-the-art, fully programmable digital waveform generation engine constitutes the heart of the
Mentor 12. It is able to control twelve independent low-level signal paths to the output section,
producing extremely accurate signals with a 3-kHz bandwidth. These signals are driven to the output
amplifiers for a stable, distortion-free 100 VA testing power. Prior to being amplified, these signals are
also available at the low-level output connectors to test and calibrate transducers, energy meters and
sensor- or Rogowski coil-based protective relays, as well as to be externally amplified for applications
that require greater current or voltage limits.
The output amplifiers of the Mentor 12 deliver a stable and efficient output, with a power curve adapted
to the most demanding test conditions. The unit can be charged with up to 6 current and 6 voltage
amplifiers, each of which supply top-quality 100 VA/W permanent power simultaneously. The resulting
1,200 VA power allows for the complete three-phase testing of two relays at the same time, including
the logical scheme and messaging functions, simulated and recorded by the 8 binary outputs and 12
inputs available in the Mentor 12.
FLEXIBILITY
You might not need twelve channels right now. Start with a
smaller configuration and add more channels when you
need them. The Mentor 12’s amplifiers are plug and play.
You just remove the unit’s side cover, slide the
amplifier(s) in, turn the unit on and continue working.
The new amplifiers will be recognized and added to all
the test and configuration screens by the Mentor 12
automatically.

POWER OUTPUTS CONFIGURATION
Regardless the number of amplifiers in your Mentor 12, you can also combine them in series and in
parallel to attain greater voltage and current levels. The output configuration screen displays a menu
with all the possible combinations and a visual guide to help you at connecting the relay. There is no
need to calculate partial current, voltage or phase angle values as the Mentor 12 manages and shows
each group of combined channels as if it were a single “virtual “one.
Furthermore, each voltage amplifier can be switched to current mode by a simple touch on the
configuration screen. This feature allows, for example, to convert a Mentor 12 3v3i (3 voltage + 3 current
channels) to a six-current test set when the need for testing three-phase differential relay arises.
Low Level Outputs and superimposed harmonics for every source can also be activated in this control.
You can accurately measure the output from a transducer, an energy meter or any other measurement device
by connecting it to the analogue or binary inputs while injecting known quantities with the Mentor 12.
PRODUCTIVITY
The Mentor 12’s human interface is organized to complete the job safely and accurately in the
shortest possible time. Locating the necessary controls and the relevant test information will take just
a few seconds to the untrained expert. The Basic Control panel has been designed especially for him.
Adjusting a few values and testing a handful of trip points in the relay is a snap, thanks to the touchsensitive panel and the rotary knob. There is no need to even look at the relay, as its response is displayed
on the control screen in real time.
The Mentor 12 includes the transient fault Playback as standard. You only need to copy your COMTRADE
files into a USB pendrive, plug it into the unit and press Playback. If you want, you can assign each
current and voltage signal in the recording to specific current and voltage channels for the playback.
You can map the recorded binary information and the response of the relay to any of the binary outputs
and inputs in the Mentor 12. You can also discard the unneeded signal’s sections or adjust the best
transformation ratio for the playback. Press Playback to examine the streamed signals and the relay’s
reactions in the screen.

The MENTOR 12’s standard equipment build up one of the most advanced
basic configurations available on the market for quick, simple and easy testing,
for both commissioning and maintenance, without the need of any PC.
MODULARITY
One of the biggest advantages of the MENTOR 12 is the "plug & play"
modularity. New amplifiers connected by the user are automatically
recognized and added to all the test and configuration screens by the
MENTOR 12, with no software adjustment. User can start with a basic 6channel unit –or even lower- and add more channels later on. The plug and
play technology makes adding or replacing channels an easy operation, with
no need to return the unit to the factory. It allows to have spare amplifiers,
to be inserted in MENTOR 12 equipment with smaller channel configurations,
or exchanged among units, providing at the same time a lower maintenance
cost. Regarding replacement modules, contact us for more details on our
unique Mentor Express Service.
The outstanding number of power outputs available in the Mentor 12 allow
for endless combinations, which along with the serial or parallel connection
of the output channels, extends the application field of the test set even to
great power demanding electromechanical type relays.
Mentor works on a Windows® CE platform which is configured to preserve
the applications and data against the typical maintenance and security
problems of personal computers, avoiding its disadvantages, but also
keeping the unit up to date, with automatic and safe internet upgrading.
