2. Mounting and installation
Heat exchanger rotor
Control unit
Motor
2.1 Basic mounting
Both the motor and the control unit are usually mounted in the heat exchanger
housing. In this way, they do not occupy any space outside of the heat
exchanger housing and are well protected during transport. Furthermore, it is
often advantageous from the point of view of interference (EMC) to place the
motor and control unit in the rotor housing.
Larger motors are usually mounted on a sprung motor support when a V-belt is
used. In this way, problems arising if non-circular rotors are used can be
prevented.
Vibration dampers should be mounted between the motor and the motor
support so that any vibration from the motor is not transmitted to the rotor
housing.

chapter 3.3 page 24.
The magnet for the external rotation monitor is mounted tight on the periphery
or in the body of the heat-exchanger. It is recommended to place the sensor
magnet close to the axis of the rotary heat exchanger. If the housing around the
rotor is magnetic itself then the sensor magnet must be isolated from the
housing. The rotation sensor is mounted to ensure that the magnet passes over
it at a distance of 5-8 mm, see
Fig. 4.

2.3 Cable connections
2.3.1 Motor
The motor is delivered with fixed connected motor cables to simplify
installation of the drive system. The length of the cables is 2.5m.
In order to secure the function of the drive system, do not change the length of
the motor cables.
WARNING! Do not install a switch between the motor and the
control unit.
2.3.2 Mains supply
An external slow-blow fuse rated at <6 A must always be installed on mains
supply. The drive system does not contain a fuse. Electronic motor protection is
built into the control unit, and monitors the motor at all times. The control
unit is protected from short circuit within the motor.
Connect the mains cables according to Fig. 7 and Table 4.
2.3.3 Communication connections
For communication signals, the used RS485 cable type should preferably be
screened and of twisted pair type to avoid EMI. The cable should be placed at
least 20 cm away from any power cables. Drop cables shall be avoided to the
extent possible. It is recommended to connect the screen of the cable to chassis/
mounting plate near to the EMX-B gland.

2.4.3 Recommendations with respect to EMC
Wrong
Correct
In order to fulfil the European EMC Directive regarding electromagnetic
compatibility, the following precautions must be taken:
The motor cable must be mounted as close to the heat exchanger housing as
possible. If the cable is too long, the excess should be collected together in the
form of, for example, a figure “8”. The area enclosed by the cable should be as
small as possible. Electrical tape or cable ties can be used to achieve this.
Fig. 9 Excess motor cable should be arranged such that the area enclosed is as
Special EMC couplings/glands are not necessary. An EMC filter is built into the
EMX-B control unit.
For communication signals, the used RS485 cable type should preferably be
screened and of twisted pair type to avoid EMI. The cable should be placed at
least 20 cm away from any power cables. Drop cables shall be avoided the extent
possible.
It is recommended to connect the screen of the cable to chassis/mounting plate
near to the EMX-B gland.

3. Built-in functions
3.1 Holding torque
Most of the time the heat exchanger rotor seals keep the rotor stationary, but if
the rotor seals are not touching the rotor and the air flow is not perpendicular to
the rotor, the air flow may cause the rotor to rotate. To prevent unintentional
heat recovery in this situation the motor is automatically used to provide a
holding torque to keep the rotor stationary.
A rotor that does require a holding torque will try to turn slowly. The drive
system immediately brakes this motion, reducing the speed to zero, and then
applies a constant holding torque to keep the rotor stationary. The holding
torque is at least 50% higher than the torque required for operation just before
stand still.
If a holding torque has been applied and you grasp the drive belt and try to turn
the heat exchanger rotor by hand, the torque will progressively increase.
The holding torque is generated by passing current through the motor phases.
The higher the torque that is required, the higher the current. This holding
current may create a sound which is perfectly normal.
3.2 Automatic purging
When the control signal is low, <0.5-0.6 VDC at 0–10 VDC (or <2.5 VDC at
2 - 10VDC depending on DIP7), the drive system switches to purging mode.
This slow rotation does not provide any significant heat transfer, but simply
serves to keep the heat exchanger rotor clean. There are two purging modes as
described below.
3.2.1 Normal purging mode
In normal purging mode, when the dip-switch DIP8 is disabled (Off) the
motor shaft turns two revolutions every 5 minutes.
3.2.2 Continuous purging mode
This purging mode is activated by dip-switch DIP 8 in the controller. When
this dip-switch is activated the normal purge mode is not valid anymore. Instead
the system will run at the lowest possible speed all the time (4 rpm or
equivalent) when the control signal is below 0.5-0.6 V

.
3.3 Rotation monitor (DIP switch 6)
Two different kinds of rotation monitors can be selected. These are used to
secure that the belt is not damaged and in other case notify the user via Rotation
alarm.
The first, UltraRotoSense™ (patent pending) is a unique, ultra-sensitive method
for detecting light load variations w/o even affecting the set operating speed of
the motor using only smart built in software algorithm in the micro controller
(no external equipment needed).
The second method, external rotation monitoring is using a more traditional
solution with external sensor and magnet mounted on the heat exchanger. This
is an alternative to UltraRotoSense™ and may be used when applicable for e.g.
the very most light weight / smallest rotors.
The rotation monitors give alarms through operating indications (LED) and via
the alarm relay (external signal) See
with this alarm.
Table 1, page 10. The motor does not stop
3.3.1 Internal UltraRotoSense
Activated by setting DIP6 to Off.
DIP switch 6 (see chapter 3.9.2 page 30) in position “OFF” (downwards),
means that the built in UltraRotoSense™ algorithm is enabled.
This method is using the motor as a sensor which means that no external
hardware is necessary for belt detection. Further, it is designed to measure load
variations even without changing the operating speed which allows continuous
belt supervision (~every other minute). This allows a very fast alarm response in
case of broken belt which may be critical for the system operating in cold
outdoor temperatures.
maintained during the belt test it will not affect the heat recovery process/room
temperature.
UltraRotoSense™ belt testing is automatically activated every other minute in all
operating states with the exception of intermittent purge mode but only if the
motor current is below a value considered as a possible no-load condition.
The controller indicates that this sequence is initiated by setting both green and
red led on at the same time. During this test the current set point speed is
maintained. The test is ongoing only for as long as necessary to detect the
presence of a load (belt intact) but for a maximum of 40 seconds. The controller
then goes directly back to normal operation.
Further, since the operating reference speed is
TM
24 Built-in functions CG Drives & Automation 01-6048-01r3
In the case where UltraRotoSense™ cannot detect a load it performs a very short
ramp as a second stage check before activating rotation alarm. During this ramp
it senses the complete motor load coming e.g. from inertia of the rotor as well as
mechanical and brush friction, air flow though rotor etc. When/If a second
stage ramp up check is performed the controller will wait for 5 minutes before
activating the next belt test. The first belt test will be performed 1 minute after
power up if the motor current is below the considered no-load level.
NOTE: In order to use internal UltraRotoSenseTM the load on the motor
should not be too low with the smallest heat exchangers.
If the load is too low for detection, use external rotation monitor instead.
3.3.2 External rotation monitor
Activated by setting DIP6 to On.
DIP switch 6 in position “ON” (upwards), means rotation monitor uses an
external rotation sensor.
The rotation monitor with external rotation sensor requires a magnet fitted on
the periphery of the rotor or anywhere on the rotor body. The magnet activates
the external rotation sensor once every revolution. Should, for example, a belt
break and the rotor stops, the pulses cease and an alarm is given. The time until
the alarm is given is speed dependent and is 16 seconds at max. speed and 20
minutes at min. speed.
It is recommended to place the sensor magnet close to the rotor axis for accurate
results.
The amplitude of output pulse from the external rotation sensor should have a
value of 8V to 12V.
3.3.2.1 LED indications
When the magnet passes the sensor, this is indicated with Green LED is Lit 1
second and Red LED is Off.
CG Drives & Automation 01-6048-01r3 Built-in functions 25
3.4 Protection of the control unit
The control unit is monitored for both over-voltage and under voltage. If the
supply voltage goes over or under the allowed limits, an alarm is triggered and
the motor stops. The motor starts again automatically when the supply voltage
returns to its normal value. The alarm is automatically reset.
The control unit has built-in motor protection that protects against overloading
and external motor protection shall not be used. Power supply to the motor is
cut in the event of overload. In order to reset the alarm, when Modbus is not
used, the supply voltage to the control unit must be temporarily disconnected
for at least 30 seconds to let stored voltage discharge. Reset is also possible by
shorten the terminals see
Table 4, page 18.
Built-in short circuit protection protects against short circuits between the
phases of the motor and between the phases and earth. If this fault is
continuously detected can it only be reset by power cycling.

Control unit
10 kOhm
Short terminal 33 and terminal 35 to activate defrosting mode. During this
mode the speed on the motor will be 4 rpm. In this case the incoming control
speed is ignored and instead 4 rpm is prioritized.
3.6 Manual control using a 10 kOhm
potentiometer
It is easy to control the drive system manually by using a 10 kOhm
potentiometer connected as shown in the figure below.
Fig. 11 Manual control using potentiometer
3.7 Test Switch
The control unit is equipped with a test switch, placed on the control board see
Fig. 5, page 16 and Fig. 6, page 17. When this switch is in the “ON” position
(up), the motor soft starts and the speed increases to the maximum,
independently of other signal sources. When in the “OFF” position (down), the
control unit goes back to normal operation.
The test switch can also be used to run the motor at maximum speed if, for
example, an external control signal is missing.
3.8 Cooling recovery
By shorting terminal 34 and terminal 35, the system will go into cooling
recovery. This means that the system will run at maximum speed.

3.10 Communication through Modbus
WARNING!
Disconnect the voltage supply before changing the DIP switch setting.
The drive unit has built-in Modbus RTU communication via RS485,
terminals 38 (A+), 39 (B-) and 40 (0 V).
Modbus communication is enabled by setting the Dip switch 10 to On.
There are two sets of baud-rate available, selected by Dip switch 9, which are as
follows:
Ta b le 8 Tw o se ts o f b a ud -ra te
Dip 9 = On Dip 9 = Off (default)
Address: 30
Baud rate/Speed: 9600
Parity bit: N, none
Stop bit: 1
Data bits: 8
When DIP switch 9 is ‘ON’ then the default parameters are 9600, 8, N, 1 .
When DIP switch 9 is ‘OFF’ then the default parameters are 19200, 8, N, 1.
None of these settings are changeable via Modbus.

The drive system has a built-in configurable function that gives a non-linear and
in second case a linear relation between the control signal and the efficiency of
the heat exchanger rather than having the speed of rotation proportional to the
control signal. This provides good conditions for stable temperature control.

4. Troubleshooting
4.1 Trip conditions, causes and remedial action
Check that:
• the equipment has been correctly installed, i.e. the cables are properly
stripped, that there are no loose cables, etc.
• motor and control unit of corresponding type size.
• check that the DIP switches are correctly set before powering the unit on.
Power cables should not be clamped together with e.g. RS485 or analogue
cables to avoid EMI.
It is always possible to test run the drive system using the TEST switch located
on the control board, see
two fixed positions, when it is in the up position, the motor accelerates to its
maximum speed independent of the control signal but dependent on DIP 1-4,
and when it is in the down position the rotation speed is set by the control
signal.
If any of the following is observed, then diagnosis should be performed to
rectify the fault.
• Motor does not reach the intended speed.
• Motor has noisy operation at reduced speed.
• High motor speed and noisy operation.
• Motor does not start to rotate.
• Control unit trips with LEDs indicating overload condition immediately
after power up without heat exchanger wheel connected.
• Control unit trips with LEDs indicating short circuit condition immediately
after power up when no heat exchanger wheel connected.
Fig. 5, page 16 and Fig. 6, page 17. The switch has
Diagnosis:
1. Check the cable connections.
2. If the connections are proper, then replace the motor alone and check for
the performance.
3. If performance is not as intended, replace the control unit.
4. Perform a motor diagnosis if the performance is not as intended after
replacing both motor and control unit.
CG Drives & Automation 01-6048-01r3 Troubleshooting 41
Motor diagnosis:
1. Disconnect power supply to the EMX-B unit and remove all the
connections.
2. Measure the resistance of the motor using a digital multi-meter. Values
should match as provided in
Chapter 5.1 page 46. Any deviations found
indicates damage to the motor.
3. Also check the connectivity between each motor phase and the PE cable.
There should ideally be no connectivity.
If the motor does not reach maximum speed or respond to the control signal,
check DIP switches. If the heat exchanger rotates in the wrong direction, change
the setting of DIP switch 5.
If the control unit is to be exchanged, the complete unit including circuit boards
must be exchanged.
WARNING!
Residual voltage remains for up to 5 minutes after
disconnection of the supply voltage. The test switch and the DIP
switches may only be adjusted when the supply voltage has
been disconnected.
NOTE: After changing dip settings the control unit must be power
cycled before the new settings become active.

Remedy
- If the motor is not running and Green LED
flashes slowly, check the drive system with
the test switch.
The motor should accelerate to its maximum
speed. If the motor does accelerate to the
maximum speed when the test switch is
activated, the fault is external.
- Is the control signal between terminals 36(+)
and 35 (-) present?
- Have + and - been swapped?
- The motor protection has been activated due
to excessive load. Check that the motor
cables are connected correctly; see the
chapter on Mounting/Connection.
- Check also that the rotor runs freely and that
the diameters of the rotor and pulley are
correct. If wrong pulley is mounted, change
pulley or change max. speed with DIP-switch
1 to 4 acc. to chapter 3.9.2 page 30.
- If the fault remains, carry out motor diagnosis.
Replace the motor if it is faulty. If the fault
does not lie within the motor, replace the
control unit.

- If the motor is faulty, replace it. If the fault
does not lie within the motor, replace the
control unit.
- The exchanger rotor does not rotate; check
the drive belt.
- If Internal rotation monitor is used, check that
the rotor or belt pulleys are not very small.
External rotation sensor error;
- Check whether the external rotation sensor is
working and providing proper pulses.
- Check function of the rotation sensor:
Measure with a Multimeter between terminal

5. Maintenance
WARNING! Residual voltage remains for up to 5 minutes after
disconnection of the supply voltage. The test switch and the DIP
switches may only be adjusted when the supply voltage has
been disconnected.
The motor and the controller do not normally require any maintenance. There
are however some things which we recommend to be checked regularly.
• Check external wiring, connections and control signals.
• Check power and motor cable connections
Preventive maintenance can optimise the product life time and secure trouble
free operation without interruptions.
For more information on maintenance, please contact your CG Drives &
Automation service partner.
5.1 Motor diagnosis
• Disconnect the supply voltage.
• Disconnect the motor cables from the control unit.
Measure the motor resistance between R–Y, Y–B and B–R. The values should
be approximately 140 Ohm for EMX-B15, approximately 40 Ohm for
EMX-B25 and approximately 28 Ohm for EMX-B35. The resistance should
not differ by more than 10 Ohm between the phases. Also check the insulation
resistance between R, Y, B terminals shorted and the motor body to ensure that
there is no short circuit to PE.
NOTE: When checking the insulation resistance, it is important to turn the
motor shaft slowly (at least one complete turn) in order to get a correct
measurement.
