3 Description
This instruction manual describes the installation and commissioning of the
Emotron M10 shaft power monitor. The Emotron M10 is a single function
monitor intended for machine builders and OEMs. It is the ideal choice for
price sensitive applications requiring only basic under- or overload protection.
For more advanced load monitoring we recommend the Emotron M20 shaft
power monitor.
The Emotron M10 is well suited for supervising induction motor driven equipment, such as centrifugal pumps, magnetic pumps, mixers, scrapers, crushers
and conveyors in applications with drive motors of up to 50 A. It can also be
used as an electronic shear pin (Motors max. 50A).
The Emotron M10 provides reliable monitoring and protection, optimizing
production equipment and minimizing expensive breakdowns and interruptions. It immediately detects any abnormal condition and initiates a warning. If
the normal machine load level is exceeded, the internal relay changes state and
the alarm LED turns red (LED is green at normal load). The output relay contact can be used for alarm indication and/or for machine shut-down.
Shaft power is calculated by measuring motor input power and subtracting the
motor power loss calculated using a unique principle. Calculating shaft power
gives more reliable supervision than non-linear techniques, such as current and
phase angle measurements. Current measurement is only sufficient at high
motor loads and phase angle only at low loads. Input power, sometimes called
true or real power, is linear but ignores motor power loss.
Using the motor as its own sensor means no external sensors or extra cabling are
required. By taking into account the motor power losses, the monitor is able to
accurately measure the shaft power supplied by the motor to the application.
This advanced technique allows the Emotron M10 to monitor the "application
load" rather than the total motor load, which includes the varying motor losses.
The monitor is easy to install and is mounted on a standard DIN rail. It is easy
to select and set up the function you wish to use, for example under- or overload
protection, relay function, response delay or alarm margin. The "Auto Set"
function can be used to set the desired load level automatically.

4 Getting Started
4.1 Please take note of the safety section
1. Pay special attention to the safety section in this manual and the parts
marked CAUTION.
2. Check that the motor/supply voltage corresponds to the values on the
Emotron M10 product label at the side of the monitor.
3. Make a note of the motor's rated power and rated current from its nameplate. Confirm that the current transformer supplied is of the correct size
according to table 1, page 11 in this manual.
4.2 Connection and set-up before first start
1. Connect the Emotron M10 according to Chapter 5 and Fig. 1.
2. Make sure all safety measures have been implemented and switch on the

Note: Monitor voltage,
see note on page 9.
The following wiring diagram provides an example of how the Emotron M10
can be connected to control the start/stop circuit of a three-phase motor, Fig. 1,
page 8. Connections to a single-phase motor are described later in this manual
(Fig. 2).
1. The current transformer CTMXXX must be placed in the same phase that is
connected to terminal 9, phase L1, see Fig. 1. Failure to follow this requirement will result in the monitor failing to function.
2. For single-phase connection see Fig. 2, page 9.
Normally the appropriate current transformer (CTM XXX) will have been
ordered and shipped with the Emotron M10. Check that this is the case; see
Chapter 6 page 11 Selection of current transformer, contact the supplier if in
doubt.
When using DC voltage, terminal 6 should be connected to negative polarity
(ground) and terminal 5 to positive polarity (max. 48 VDC), see Fig. 1, page 8.
See also the alternative auxiliary circuit Fig. 11, page 29.

When using DC voltage, alternatively see Fig. 11, page 29.
If terminal 5 is not connected, see Fig. 3, the alarm is not automatically reset
when the machine load is normal again after an alarm situation. The alarm is
then latched; function "Latched alarm". The alarm can then be manually reset
by pressing both PAR and VAL buttons at the same time for 3 seconds. It is only
possible to reset an alarm if the power level is on the "right side" of the set alarm
level (depending on under- or overload monitoring).
If, however, terminal 5 is connected to an AC or DC signal the alarm will be
reset automatically (un-latched alarm). This is only possible if the power level is
on the "right side" of the set alarm level.
