MCM User's Manual
Lethal voltages and currents are present at the input terminals of this device. Accordingly, this MCM unit
should be installed and maintained only by qualified, competent personnel who have the necessary training
and experience appropriate to high voltage and current devices. MCM must be used in accordance with all
local and national codes for the installation and operation of electrical equipment.
Recommended safety precautions should be followed at all times. Both current and voltage transformers can
present lethal currents and voltages when their primaries are energized and standard practices (i.e. shorting
the secondaries of current transformers and removing voltage transformer fuses) must be respected during
installation or any subsequent service.
The unit is designed for operation in a control cabinet with restricted access to the rear terminals and should
not be used in any environment where this is not the case. MCM should not be used for the purpose of
primary protection of electrical equipment.

1 Welcome to MCM
1.1 Introduction
MCM is a revolutionary tool in the battle to keep electric motors and machinery running at peak
performance, whilst maintaining high plant productivity levels. Used correctly, this unique instrument is
capable of monitoring three phase AC motors of all sizes and power levels to provide clear, unambiguous
indications when the performance of a particular motor (or even the machinery it is connected to) begins
to degrade. The numerous transducers employed by other, less advanced instruments have been
replaced by three current sensors and three voltage sensors, familiar to all those involved with the
measurement of electrical quantities, making the system straightforward to install and use without in-
depth training of personnel.
In addition to its unique capabilities as an intelligent condition-monitoring device, MCM can also perform
many of the functions of, and indeed replace the more traditional energy monitoring and data-logging
instruments.
For applications involving the monitoring of many motors and associated machinery, the networking
options available with MCM allow units to be connected together to a host terminal where they can all be
viewed together.
Furthermore, the monitoring software package allows examination of the various parameters MCM uses
to determine the status of a motor and to trend the parameters as a visual indication of degradation over
time.
Despite its simplicity and ease of use, like any intelligent electronic, software-based device, it is
important that MCM is installed and used correctly. We recommend strongly that you take the time to
study the information contained within the accompanying manuals and to familiarize yourself with the
operating principles and practices.
Customer service: Please contact either your supplier or Artesis AS Customer Service if you
experience any problems in the installation or use of MCM.

1.2 Use of this manual
This manual explains the basic concepts needed to install and use MCM. The appendix at the end of the
manual provides information that may be useful to the general user. For further, specific details please

2 MCM Installation
2.1 Preliminary checks
Please inspect the contents of the MCM package and ensure that they agree with the information in the
Packing list. In the event of any missing or damaged items, please contact your supplier immediately.
Check also that the power range of the MCM unit is suitable for the motor to be monitored. The device
type can be found on the MCM label. Artesis A.S. will not accept responsibility for damage caused to or
by any MCM unit that has been incorrectly installed or installed on a motor system outside the indicated
power range.
2.2 MCM Unit Installation
MCM has been designed to mount directly onto the front panel of the motor switchgear cabinet. Any
other usage is not recommended due to the lethal voltages present at the terminals. To mount,
insert the MCM unit into the prepared 91x91 mm cutout on the cabinet panel and push until the front of
the unit is flush with the panel. Insert the side retainers and tighten the thumbscrews on each retainer
until the MCM unit is held securely in place.
Mounting MCM on a panel
In common with any device connected to high power electrical
supplies, only suitably qualified personnel should install and maintain
MCM.

2.3 Current and Voltage Sensor Installation
Dangerous and lethal voltages can develop across the secondary
terminals of open circuit current and voltage transformers. Before
disconnecting any MCM unit to or from a current transformer, the
secondaryterminals of the transformer should be shorted using a link
capable of carrying at several times the nominal output current (i.e. at
least 10A). Before performing any work on a voltage transformer, its
fuse must be removed or switch opened. Contact breakers or fuses at
their sources must protect all voltage inputs.
2.3.1 Low voltage line driven systems
Three standard 5A secondary, current transformers of appropriate ratings are recommended for current
sensing (please refer to the appendix at the end of this manual for full specifications). The secondary
terminals of each transformer should be connected to the corresponding current measurement terminal
pairs, I11-I12,I21-I22, I31-I32, on the rear of the MCM unit.
Voltage line connections VR, VS, VTshould be made directly to their respective voltage measurement
terminals V1,V2,V3at the rear of the unit.
Please refer to the connection diagrams in the appendix at the end of this manual for further details.
2.3.2 Low voltage inverter driven systems
The current sensors employed by MCM for inverter driven systems are Hall-effect type requiring an
external DC power supply. The motor current rating should be checked carefully to ensure compatibility
with the sensors provided. Please refer to the appendix at the end of this manual for further details on
sensor selection.
High current sensors (for currents greater than 200 A) need to be mounted separately at a convenient
location within the switchgear cabinet together with their external power supplies. Smaller sensors are
mounted on the same circuit board as the power supply and should be placed together at the chosen
location. In both cases, the cable carrying power to a single phase of the motor must be passed through
the central hole in the appropriate current sensor and secured.
The power supply ground should be connected directly to the I12, I22, I32 pairs of current measurement
terminals on the rear of the MCM unit.
Voltage connections VR, VS, VTshould be made directly to their respective voltage measurement
terminals V1V2V3 at the rear of the unit.
Note that MCM is not recommended for use with inverters operating at a chopping frequency
lower than 2 kHz.
Please refer to the connection diagrams in the appendix at the end of this manual for further details.

2.3.3 Medium/High voltage systems
Three standard 5A secondary, current transformers of appropriate ratings are recommended for current
sensing (please refer to the appendix at the end of this manual for full transformer specifications). The
secondary outputs from each transformer should be connected to the corresponding current
measurement terminal pairs, I11-I12,I21-I22, I31-I32, on the rear of the MCM unit.
If compensation capacitors are employed, it is essential that the current
transformers be placed between the motor and the capacitor bank so that only
the true motor currentsare measured.
Standard 100V, 110V and 120V secondary voltage transformers should be used to drop the voltage to
usable levels. Connections from the secondary outputs of the transformers should be made to the
respective voltage measurement terminals V1,V2V3 at the rear of the unit.
Please refer to the connection diagrams in the appendix at the end of this manual for further details.
2.4 Rear panel connections
Connections to the MCM rear panel are given in the following figure. Lethal voltages can be present at
the voltage and current terminals and it is vitally important that power is removed from both the motor
and the MCM unit prior to any connections being changed.
REMOVE ALL POWER PRIOR TO CHANGING CONNECTIONS
The three motor power voltages should be connected to the corresponding measurement terminals on
the MCM rear panel (R phase to V1, S phase to V2, and T phase to V3) using the connectors provided.
Similarly, the IR, IS, ITconnections from the current sensors should be made to the appropriate current
terminal pairs, I11-I12,I21-I22, I31-I32, on the upper part of the rear panel. It is not essential that the all three
sets of phases have the correct phase relationship as the phase ordering is determined by MCM.
The order of these voltage and current pairs is not important as MCM determines the correct ordering
when CHECK MOTOR is first run on the device
