and is safe to operate when delivered.
Disregarding the notices in these installation and operating instructions may lead to life-
threatening injuries!
4Carefully read the installation and operating instructions and follow their content.
4Observe local accident prevention regulations and general safety regulations that apply in
the area of use.
Intended use
Pallet Control may only be used for industrial applications and in an industrial environment to
control one or two Interroll Pallet Drives or gear motors.
Pallet Control must be integrated into a conveyor module or conveyor system. Any other use is
considered inappropriate.
Any modifications that affect the safety of the product are not permitted.
The product may only be operated within the defined operating limits.

Translation of original operating instructions
Personnel qualification
Unqualified personnel cannot recognize risks and, as a result, is subject to greater dangers.
4Authorize only qualified personnel to perform the activities described in these instructions.
4The operating company must ensure that personnel follow locally applicable regulations and
rules about safety and hazards while working.
The following target groups are addressed in these instructions:
Operators Operators have been instructed in the operation and cleaning of the product, and follow the
safety guidelines.
Qualified person A specialist is a person who, based on his relevant technical training, education and experience,
is capable of detecting risks and avoiding dangers that could occur during the use of the
product.
Electricians An electrician has technical training and, based on his or her knowledge and experience, as well
as knowledge of relevant provisions, is capable of properly performing work on electrical
equipment. He or she can independently recognize potential dangers and avoid personal injury
and property damage from electrical voltage.
In principle, all work on electrical equipment may be performed only by a trained electrician.
Dangers
The following list provides information about the various types of danger or damage that may
occur while working with the Pallet Control.
Bodily injury 4Work on the device must be performed only by authorized electricians in accordance with
applicable regulations.
4Before using the product, ensure that no unauthorized personnel is in the vicinity of the
conveyor.

Product information
Product description
Pallet Control is a decentralized control for pallet conveyor systems that allows for operating up
to two Pallet Drives or gear motors. Two versions are available, which differ by the maximum
permissible current. Pallet Control can be controlled as follows:
• via a RollerDrive control system, such as MultiControl
• PLC
• directly via the digital inputs

By combining Pallet Control with a RollerDrive control system, it is possible, among other things,
to implement zero pressure accumulation conveying of pallets. It is also possible to control drives
with integrated brakes.
Various protective mechanisms are integrated, such as analysis of the thermal contact and
overload detection. Error messages are signaled via LEDs that show different flashing patterns
depending on the malfunction.

Assembly and installation
Warning notices for installation
NOTICE
Risk of property damage that may cause failure or shortened service life
4Check each Pallet Control for visible damage before installation.
4Ensure that the Pallet Control is not warped during installation (no bending or torsion).
4Do not drill additional mounting holes into the housing or enlarge the holes provided.
4Do not drop the Pallet Control to prevent internal damage.
4Install the Pallet Control only in a horizontal position on the conveyor frame in such a way
that the labeling can be read. Other variants are not allowed and require the approval of
Interroll.
NOTICE
Protection class IP54 is ensured only with proper installation.
4Close the housing correctly. The tightening torque of the housing screw is 2.8Nm.
4Firmly tighten cable connections or, if not used, apply dummy caps.
4Close USB cover.
Installation
The rear plate features three holes for M5 screws for fastening the Pallet Control to the
conveyor frame. The PC 6000 is intended for installation on a metal frame.
If possible, install all Pallet Controls only on one side of the conveyor system to simplify the
electrical installation.
4Identify a flat area on the conveyor frame where the Pallet Control can be installed. Do not
use any spacer bushings.
4Ensure that there is sufficient space for the cable entry on the left and right.
4Hold the Pallet Control to the conveyor frame and mark the center of the installation holes.
Observe the correct orientation of the housing.
4Drill three holes with ø 5.5 mm at the markings in the conveyor frame.
4Screw the baseplate onto the conveyor using M5 screws.
4Ensure that the rear plate is not twisted.

Warning notices concerning the electrical installation
DANGER
Danger to life – electrocution
Improper electrical installation can cause life-threatening electric shocks or damage to the Pallet
Control.
4Only have an electrician undertake electrical installation work.
4Observe national regulations for electrical installation. Within the EU, IEC 60204-1 must be
met at a minimum.
4Before installing, wiring or removing the Pallet Control, switch it off and ensure that it cannot
be started accidentally.
4The Pallet Control may be operated only with AC voltage at a nominal voltage of 400 V 50
Hz and 24 V DC and a maximum permissible deviation according to the technical data.
4Proceed with caution when connecting the Pallet Drive to avoid damaging the magnetic
sensor on the printed circuit board.
4Ensure that the control systems, motors and power sources connected to the Pallet Control,
as well as the entire conveyor system, are correctly grounded. Incorrect grounding can result
in the build-up of a static charge, causing the Pallet Control to malfunction or fail
prematurely.
4Ensure that the existing electrical installation does not interfere with the Pallet Control.
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 cables have been connected.
4Do not apply too much tension or pressure to the plug. When bending the cable at the plug,
the insulation of the cable may be damaged and the Pallet Control may fail.
4Install a suitable protection mechanism so that the Pallet Control and the line are not
overloaded.
4The protective mechanism must be arranged in a suitable manner and easily accessible.
4The protective mechanism must be identified as disconnect device for the PC 6000.
4Have an electrician undertake the dimensioning of the protection mechanism.
4Observe the technical specifications!
4When selecting the circuit protection, pay particular attention to the maximum short circuit
current of the voltage supply.
