WIRING
This wiring example shows how the M20 can be used to control the
starting and stopping circuit of the motor. Other wiring configura-
tions are possible.
1. The current transformer CTMxxx must be placed in the same
phase that is connected to terminal 9, phase L1.
2. For single-phase connection see fig 2.
Fig 1. Connection example
Note!
If the START/STOP is connected according to fig. 1, it is recommended that
terminals 6 and 7 be by-passed during programming. After the programming
is completed the by-pass must be taken out.

INSIDE THE BOX …
This instruction manual describes the installation and commissioning
of the M20 load monitor. The M20 supervises induction motor driven
equipment and provides alarms when abnormal conditions are
detected. The M20’s ability to provide reliable monitoring & protec-
tion ensures production equipment is optimised and expensive break-
downs and interruptions are minimized. Due to the special method of
subtracting motor power losses, the monitor is able to accurately mea-
sure the shaft power supplied by the motor to the application. This
advanced technique allows the M20 to monitor the “application” load
only as opposed to the “total” motor load, which includes the varying
motor losses.
• Check the delivery. Your shipment should contain the M20 load
monitor, a current transformer and this instruction manual.
• Check carefully that the ordered equipment complies with the
motors input voltage and that the current transformer rating is as
stated on the delivery packaging.
• Check that the contents have not been damaged in shipping.
Note!
If in doubt contact your supplier before starting to install or commissioning
the product.
1SAFETY
• Study this manual thoroughly before installing and using the
monitor.
• The monitor must be installed by qualified personal.
• Always disconnect supply circuits prior to installing.
• The installation must comply with standard and local regulations.
• Pay special attention to this SAFETY section and the part marked
“CAUTION!” in the OPERATION section.
• Should questions or uncertainties arise, please contact your local
sales outlet or see section 11 SERVICE.
Note!
Do not remove or break the seal on the housing. The warranty will be can-
celled.

Note!
Normally the appropriate Current Transformer (CT) will have been ordered
and shipped with the M20, check that this is the case; contact the supplier
if in doubt.
Note!
The transformer connection and orientation are not polarity sensitive.

SELECTION CURRENT TRANSFORMER
FOR MOTORS LESS THAN 100A
1. Check the rated motor current on the motor plate.
2. Compare this value with the current in table 1.
3. From table 1, select the current transformer and the appropriate
numbers of windings.
EXAMPLE:
• Rated motor current = 12A.
• Select 10.1-12.5A from the first colon in table 1.
• This gives:
- CTM025 with 2 windings.
Table 1. CT less than 100A.
Note!
Max length of the CTM cable is 1 m (39.37 in).

4Start Window

Set the START DELAY (window 31)
A START DELAY must be set to allow the motor and machine to
speed up and to allow the power in-rush currents to be ignored by the
monitor.
Programming
1. Determinein seconds, how long it takes forthe motor and machine
to reach speed and for the power in-rush to pass. This will be the
minimum START DELAY.
2. Go to window 31 (default = 2.0s).
3. Press or to set the determined START DELAY time in
seconds.
4. Press to confirm the change.

Set the RESPONSE DELAY (Window 32)
A RESPONSE DELAY allows the machine to remain in an over- or
underload condition for a specific time before the alarm relays are acti-
vated.
Programming
1. Determine in seconds, how long an under- or overload condition is
allowed. This depends on machine properties and behavior. This
will be the RESPONSE DELAY.
2. Go to window 32 (default = 0.5s).
3. Press or to set the determined RESPONSE DELAY time in

Set HYSTERESIS (Window 33)
The HYSTERESIS of an Alarm level prevents the alarm relay “chatter-
ing” if the load fluctuates even in a normal “stable” condition . Apply
also for pre-alarm. This feature is normally only used if the “Main
Alarm Latch” (Window 61) is set to “OFF”. Default = 0%.
Fig. 10 Hysteresis
Set MAIN ALARM LATCH (Window 61)
The MAIN ALARM LATCH keeps the MAIN ALARM output active,
even if the alarm condition has been removed (relay R1). A latched
alarm output can be reset by:
•theresetkey
• external reset via Digital input (see window 81).
• switching of the power of the monitor (see also “Wiring”).
Default = OFF.
Set ALARM AT NO MOTOR CURRENT (Window 62)
The “ALARM AT NO MOTOR CURRENT” gives an alarm if the
motor current becomes zero (ON). Default = OFF (No alarm at no
motor current).

Set Alarm levels with AUTOSET
The AUTOSET command performs a measurement of the actual
motor load and automatically sets the relevant Alarm levels depend-
ing on the selected monitor function.
Programming
1. Start the motor and let it run at the normal machine load, until the
START DELAY has expired.
2. Press for 3 seconds. This can be done in any window.
3. The display shows “SEt”, to confirm that the AUTOSET level has
been measured and the Alarm levels have been set. The display
reverts to window 01.
4. If the alarm levels are too high or too low, readjust the appropriate
MARGINS (see table above) and perform a new AUTOSET. Alter-
natively, alarm levels can be set manually - see section 7.

Set ALARM LEVELS manually (Window 11-14)
The alarm levels can be set manually, without using the AUTOSET.
Also after an AUTOSET has been performed, these levels can be read-
justed e.g. for fine-tuning.
Set MARGINS (window 21-24)
The MARGINS for the AUTOSET can be changed manually. After the
adjustment, the AUTOSET action must be performed once again to

TROUBLESHOOTING
Problem Solution
Window 01 always shows zero load,
even if the motor is running
- Check the connection of the current
transformer(s).
- Check that value of the rated motor power in
window 41 is the same as the rated motor power
on the motor plate.
- Check that window 03 shows a phase current
value in correspondents with the rated motor
current.
Window 03 shows an improper value
of the phase current
- Check that current transformer has been
selected according to the tables 1 and 2.
- Check that the number of windings is according
to table 1 and 2.
- Check that the value of the motor current in
window 42 is the same as the value of the motor
current on the motor plate.
The monitor never gives an alarm - Check that window 01 shows a value greater
than zero.
- Check the alarm levels in windows 11 to 14. If
not correct readjust the levels or per form an
AUTOSET.
The monitor always gives an alarm - Check the alarm levels in windows 11 to 14.
If not correct readjust the levels or per form an
AUTOSET.
- Check if the monitor is programmed for “latched
alarm” (window 61=on). If so reset the monitor
by pressing the reset key.
Window 00 shows “LU” or “OU”.
Under- or over voltage alarm.
Switch off the supply:
- Check that the supply voltage is corresponding
with the voltage range on the monitor type plate.
Window 01 shows “oor”. "Out Of
Range" alarm.
- The measured shaft power is higher than 125% of
the rated motor power programmed in window 41.
Window 03 shows “oor”. “Out Of
Range” alarm.
- The measured motor cur rent is higher than 125%
of the rated motor cur rent programmed in
window 42.
The alarm relays are not switching - Check that the wire links between terminals 6
and 7 are removed according to “Wiring”.

Reset to FACTORY DEFAULTS (Window 99)
The FACTORY DEFAULTS are reset by entering “dEF” in window 99.
If Window 99 shows “USr” it indicates that the settings have been
changed to user specific settings.

Set ANALOG OUTPUT (Window 91)
The ANALOG OUTPUT provides an analog signal of either 0-20 mA
or 4-20 mA signal which represents the motor shaft power. The signal
can be inverted. Full scale: rated motor power.
Fig 12. Analog Output.
LOCK PARAMETERS (Window 04)
To avoid unintentional change of parameter settings the program-
ming can be locked by entering the code “369” in window 04. Now
only the motor variables LOAD [01], VOLTAGE [02] and CURRENT
[03] can be checked. Follow the same procedure to UNLOCK the
monitor. The AutoSet button is disabled when parameters are locked.
AutoSet via Digital Input is always active if window 81 is set to AU
(AutoSet).
Note!
The “Lock” symbol appears in all windows.
