Product information
Product description
The MultiControl is a control for conveyor systems that can control up to four motors. At the
same time, it is also a certified I/O device for PROFINET, EtherNet/IP and EtherCAT and, as such,
can be networked with other MultiControls and a PLC.
Sensors and RollerDrive can be integrated directly into the fieldbus layer via the MultiControl.
This allows saving a complete additional sensor/actuator layer.
The MultiControl can easily and flexibly be configured via a PLC programming environment, a
web user interface or the Interroll Teach-In procedure. The procedure simplifies and shortens the
startup time on site and also enables the simple exchange of a single MultiControl.
If a special conveyor logic is to be used, the MultiControl can be equipped with a special
software by Interroll. As a result, it can be used as an individual control system – with or without
connected PLC.
The MultiControl is compatible with all 24-V conveyor modules from Interroll Automation GmbH.
So-called ZPA+ programs are used to operate the conveyor modules. These programs are
described in a separate operating manual. The functions of the ZPA programs are also
described in a separate operating manual.
Teach-In procedure To provide an easy startup of large conveyor systems with many zones, it is possible to
automatically configure MultiControl. For this purpose, the fault signals or operational currents
of the connected motors as well as the signals of at least two adjacent zone sensors are
captured and analyzed and used to determine or specify the following settings:
• The number of motors connected to every MultiControl
• The number of zones per MultiControl
• The network address of every MultiControl
• A name assignment for every MultiControl
• The neighboring relations of the MultiControl
• Rotating direction of the motors for downstream transport
The function of the teach-in procedure is described in a separate operating manual.
Energy recovery /
Overvoltage protection
If the RollerDrive is braked or stopped, the kinetic energy of the RollerDrive (and the material
being conveyed) will be converted into electrical energy. This energy is fed back into the system
where it can be used by other RollerDrive.
If the energy recovery is higher than the energy demand the excess energy is converted into
heat by a brake chopper integrated in the MultiControl. The brake chopper is activated when
the voltage exceeds 25.2V. As such, excessively high voltages within the system are avoided.
Overload protection
device
If the brake chopper is activated for more than two seconds, it is switched off again since it is
assumed in this case that the power supply delivers an incorrect voltage. If overload protection is
active, this is shown on the LED display. As long as overload protection is active, the motors
cannot be switched on.

Assembly and installation
Warning information for assembly
NOTICE
Risk of damage leading to failure or shortened life expectancy
4Check each MultiControl visually for damage before assembly.
4Make sure that the MultiControl is not warped during installation (no bending or torsion).
4Do not drill additional mounting holes in the casing or baseplate or enlarge the holes
provided.
4Do not drop the MultiControl to prevent internal damage.
Assembly of MultiControl
Initial assembly To fasten the MultiControl at the conveyor frame, the supplied baseplate must first be mounted
on the conveyor frame. The baseplate features two sets of two holes for fastening the
MultiControl. The left-hand holes should be used for initial assembly.
To simplify electrical installation, if possible all MultiControl should be assembled on the same
side of the conveyor. In the case of curves, wherever possible the MultiControl should be
assembled on the outside radius as the RollerDrive connection is on this side.
The distance from the top edge of the MultiControl to neighboring components must be at least
10mm to be able to operate the magnetic sensor.
4Identify a flat area on the conveyor system frame on which the MultiControl can be
assembled. Ensure that there is approx. 25 mm space to the left of the designated area in
order to be able to move the MultiControl at a later date if necessary (see "Repeated
assembly", page17).
4Use the baseplate as a template and mark the center of both mounting holes. Pay attention
to the correct orientation of the baseplate (the labeling in the cable duct must be readable).
4Drill two holes with a diameter of 6.5 mm on the markings in the conveyor frame.
4Screw the baseplate onto the conveyor using M6 screws.
4Ensure that the baseplate is not distorted.
4Insert flat cables for the voltage supply (see "Connect the power supply", page19).

4Place the MultiControl onto the left hole in each case and push it down until the locking
mechanism engages.
4Fasten the MultiControl with the available screws in MultiControl and a Phillips screwdriver
onto the baseplate according to DINENISO4857-Z2. Maximum tightening torque 2 Nm.
This drives the contact pins through the flat cable and establishes contact with the voltage
supply.
To ensure a proper fastening of the MultiControl on the baseplate, only the screws supplied may
be used. If they are being damaged or lost, they can be reordered from Ejot using article
number 4280049809 (http://www.ejot.com).
Repeated assembly If an already connected MultiControl has to be removed from the backplane, the flat cable must
not be reconnected at the same point as otherwise a proper contact cannot be ensured. To
avoid the flat cable having to be removed and repositioned on all MultiControl, in this case the
MultiControl can be attached via the right-hand mounting hole in each case. Consequently, the
position of the MultiControl to the flat cable changes and the flat cable can be reconnected at a
different point. The insulation is self-healing which means protection rating IP54 is achieved.

Warning notices concerning the electrical installation
Improper electrical installation can leads to damage of the MultiControl.
4Only have an electrician undertake electrical installation work.
4Observe national regulations for the electrical installation. Within the EU, IEC 60204-1 must
be adhered to at a minimum.
4Before the installation, wiring or removal of the MultiControl, de-energize it and secure it
against inadvertent reactivation.
4The MultiControl may be operated only with DC voltage with a rated voltage of 24V and a
maximum permissible deviation of ±5%.
4The MultiControl may be operated only with a protected extra-low voltage (PELV according
to IEC 60204-1).
4Never operate the MultiControl with AC voltage since this will lead to unrepairable damage
to the device.
4When connecting the MultiControl, observe the correct polarity of the voltage supply.
Reversing the polarity leads to unrepairable damage to the device and the connected
motors.
4Ensure that no hazardous voltage can come into contact with the connections or the housing,
not even in the event of a malfunction or fault.
4Place all voltage supplies used on a common ground potential to avoid equalizing currents
via the MultiControl or the bus line.
4Ensure that the RollerDrive, VDC motors and voltage sources connected with the
MultiControl, as well as the entire conveyor system, are correctly grounded. Incorrect
grounding can result in the build-up of static charge, causing the MultiControl to malfunction
or fail prematurely.
4Ensure that the existing electrical installation has no interfering effect on the MultiControl.
4Use only cables that are sufficiently dimensioned for the specific operating conditions.
4Do not forget to observe the calculations for voltage drop on electrical lines.
4Observe the regulations for routing cables.
4Use suitable switching equipment and protective devices to ensure safe operation.
4Only apply operating voltages when all of the cables have been connected.
4Do not apply too much tension or load to the plug. When bending the cable at the plug, the

Electrical installation
Connect the power supply One or two flat cables of type 3G3G-FL with a core cross-section of 2x 2.5mm² are used for
the power supply:
• When using a flat cable, the MultiControl, the RollerDrive, the sensors and the logic are
supplied by the same voltage source.
• If two flat cables are used, the sensors and the logic are supplied with separate voltage
sources. This allows the RollerDrive to be switched off without losing the bus communication.
The two ground potentials (L-) of the voltage supply are connected with each other in the
MultiControl. The two positive contacts (L+) are connected with each other via a diode in the
MultiControl. This ensures that the logic can also be supplied via the RollerDrive line, but not the
RollerDrive via the logic supply.
4Observe the national regulations for laying the flat cables. DIN EN 60204-1 applies in
Europe.
4Use only flat cables of type 3G3G-FL with a core cross-section of 2x 2.5mm².
4Insert the flat cable in the cable duct on the base plate in its correct orientation without
mechanical tension and without torsion. The cable ducts have a form-fit design (see graphic).
As such, the flat cable can only be laid in one direction and polarity cannot be reversed.

4If only one voltage supply is used, use the top cable duct with the label "Power
RollerDrive" (1). In this case, close the lower cable duct (2) with a stub to achieve protection
rating IP54.
4If necessary take measures for strain relief or vibration reduction.
4Close the ends of the flat cables with end caps to achieve protection rating IP54.
4Install MultiControl on the base frame to establish the correct contact bonding (see "Initial
assembly", page16).

4Connect the line to the voltage source by connecting the brown core at L+ and the blue core
at L-.
If the MultiControl has to be removed after bonding, the flat cable must not be reconnected at
the same point as otherwise a proper contact cannot be ensured. In this case, the MultiControl
has to be repositioned (see "Repeated assembly", page17).
NOTICE
Short circuit from incorrect polarity
If the voltage supply is connected with incorrect polarity, it leads to a short circuit in the line
because of the reverse polarity protection in the MultiControl.
4Install a suitable protection mechanism so that the MultiControl and the line are not
overloaded.
4Have an electrician undertake the dimensioning of the protection mechanism.
4When selecting the line protection, pay particular attention to the maximum short circuit
current of the voltage supply.
Connecting the RollerDrive The four connectors 'RD1' to 'RD4' are prepared for the RollerDrive EC310. The RollerDrive
EC310 connection cable is already fitted with a suitable plug.

4Insert the plug so that the labeling EC310 on the plug points to the rear, i.e. it cannot be
read.
4Close unused RollerDrive connections with M8 dummy cap to achieve degree of protection
IP54.
NOTICE
Connections are not short circuit-proof
In case of a short circuit, particularly between Pin 1 and Pin 3, the internal fuse in the
MultiControl trips. The internal fuse cannot be replaced.
4Ensure the correct polarity.
