Safety-related information
2 Safety-related information
2.1 State of the art
The RollerDrive EC310 has been constructed with respect to applicable standards and the current state of the art and
has been delivered in a condition that is safe to operate. Nevertheless, hazards can occur as a result of use.
Non-compliance with the instructions in this operating manual can result in life-threatening injuries.
In addition, the applicable local accident prevention regulations for the area of application and general safety
regulations must be adhered to.
2.2 Proper use
The RollerDrive may only be used in an industrial environment for industrial purposes within the stipulated
It must be integrated into a conveyor unit or conveyor system before commissioning.
Application eld
Drive for unit load conveyor technology, such as for the transportation of cardboard boxes, containers, barrels,
workpiece carriers or tyres.
The RollerDrive is suitable for:
• Zero-pressure roller conveyors
• Entry conveyors
• Roller conveyor curves
• Small belt conveyors
Depending on the area of application of the RollerDrive, PolyVee, round or toothed belts can be used for the power
transmission.

Safety-related information
2.3 Improper use
Any use that goes beyond the proper use is considered improper, unless this has been authorised by Interroll
Engineering GmbH where applicable.
The equipment must not be installed in areas in which substances could form explosive atmospheres/dust atmospheres
or for application in the medical/pharmaceutical sector.
It is considered improper use to install the equipment in exposed spaces that are open to potentially adverse weather
malfunction as a result.
The RollerDrive is not intended for use by private end users. The equipment must not be used in a residential
environment without further examination and without the use of EMC protective measures that have been adapted
accordingly.
It must not be used as a safety-relevant component or for performing safety-relevant functions.
The use of the RollerDrive in generator-only mode is prohibited, as it is theoretically possible (for example, roller
RPM> 90 RPM with gear ratio 98: 1) to exceed the maximum allowable contact voltage of 60 V DC on the connector.
2.4 Qualication of personnel
¾
¾The operating company is responsible for ensuring that personal adhere to the locally valid rules and
regulations for working in a safe and risk-aware manner.
This operating manual is intended for the following target audiences:
Operators
Operators are trained in how to operate and clean the Interroll power supply unit and follow the safety regulations.
Service engineers
The service engineers have a specialist technical education or have successfully completed a training course from the
manufacturer. They carry out repair and maintenance work.
Qualied electricians
as knowledge of applicable regulations, they are able to carry out work on electrical equipment in an appropriate
manner. They are able to identify hazards independently and prevent electrical damage to persons and property.

Safety-related information
2.5 Dangers
with the operation of the RollerDrive.
Injury to persons
¾Maintenance and repair work on the unit must only be carried out by authorised technical personnel in
compliance with the applicable provisions.
¾Before switching on the RollerDrive, ensure that no unauthorised personnel are situated in the vicinity of the
conveyor/conveying system.
Electricity
¾Installation and repair work must only be carried out when the system has been disconnected from the power
supply.
¾
Rotating parts
¾
¾Persons with long hair should wear a hair net.
¾
¾Do not wear items of jewellery such as chains or bands.
Heat
¾Do not touch the RollerDrive during operation. In applications with high switching cycles, the temperature of the
tube can reach up to 60 °C.
Work environment
¾Remove any materials and objects that are not required from the working area.
¾Wear safety shoes.
¾Stipulate that the material to be conveyed must be set down carefully and monitor this to ensure it is carried
out correctly.
Faults in operation
¾Regularly check the RollerDrive for visible damage.
¾In the event that smoke begins to form, unusual sounds are heard or the conveyed material becomes jammed
unintentionally switched on again.
¾Immediately contact specialist personnel to determine the cause of the malfunction.

Safety-related information
Maintenance
¾
visible damage on a regular basis.
¾Never open up the RollerDrive.
Unintentional start-up
¾Ensure that the RollerDrive cannot be switched on unintentionally, particularly during assembly and
maintenance work or in the event of a fault.
2.6 Interface to other devices
The integration of the RollerDrive into a conveyor system can create additional potential hazards. Such potential
hazards are not covered by this operating manual and must be analysed during the development, installation and
commissioning of the conveyor system as a whole.
¾Following the integration of the RollerDrive into a conveyor system, the entire system must be checked for any
new potential hazards that may be present before the conveyor is switched on.
2.7 Operating modes/operating phases
Standard operation
Operation in the installed condition at the end customer as a component in a conveyor in an overall system.

Product information
3.2 Product description
The RollerDrive EC310 can be used in both straight and curved sections and ensures a constant conveyor speed.
Motors, motor electronics and gears are installed in the RollerDrive.
Overload protection
The system has multiple overload protection systems:
Stall timing
If the RollerDrive is jammed and a start signal is issued, it will try to restart for a second every three seconds for
a total of a ten times. If the blockage is still present after these ten attempts, an error signal will be issued and the
RollerDrive will attempt to restart in a 60:1 cycle (where a restart is attempted for a second every 60 seconds) until
the blockage has been eliminated.
The RollerDrive will not be damaged if the system runs in stall timing mode for an extended period. The error signal is
reset if the RollerDrive begins running again at the selected speed or the start signal is cancelled.
Low speed
If a deviation from the selected speed of more than ±20% occurs for more than ten seconds, the RollerDrive is
reset if the RollerDrive begins running again at the selected speed or the start signal is cancelled.
Temperature monitoring
The temperature of the motor installed in the RollerDrive is monitored in addition to the temperature of the motor
issued. Once the overheated components have cooled down, the error signal will be reset.
If the RollerDrive cools down and the start signal is still active, the RollerDrive may start up again
unintentionally. Troubleshooting must be carried out via the control system.

Product information
Holding brake (zero motion hold)
The RollerDrive EC310 is equipped with an electronic holding brake that allows it to be used in sloped and ascending
conveyors. For this, the RollerDrive is held in position if no start signal is issued. If the power supply system fails, the
Energy recovery system
The RollerDrive recovers energy when braking the conveyed material. This results in the motor and motor electronics
heating up less and improves the energy balance of the system. The Interroll controls are equipped with a circuit that
prevents an increase of voltage in the power supply.
If motor controls are used without a voltage limiter (brake chopper), it must be ensured that the power
supply units used are suitable for energy recovery.
