TECHNICAL MANUAL FOR THE RDR BL3 - V1.1 DRIVE ROLLER Rev. 21/09/2018 page 35
13 RECAPITULATION OF INSTRUCTIONS FOR ENSURING EFFICIENT OPERATION OF THE RDR DRIVE
ROLLER
- Make sure that the Drive Roller received matches order specifications.
-
NEVER pull the Drive Roller by its power cable.
- Make sure that the chosen Drive Roller complies with the torque and speed requirements for conveying
packages.
- Install the Drive Roller, making sure that you have tightened the screws to the correct torque value, i.e.: 65
Nm for the M12 nut on the cable output side and 15 Nm for the M8 hexagonal head screw.
-
If configuring with Poly-V pulley, make sure that the Poly-V belt is positioned correctly in the seats of the
pulley and has a rectilinear position with respect to the pulley of the subsequent roller.
- Make sure that the connecting cable of the Drive Roller has a suitable radius at the pin output so that cable
does not get pinched or deformed.
- Check the cabling of the connecting wires. They must follow the instructions described in this document. No
other connection method can be considered to be acceptable.
-
Make sure that the non-connected wires have been properly insulated.
- Make sure that you have connected the necessary wires suitably and have protected the connections from
possible short circuits.
- Make sure that the structure of the conveyor is properly connected to the ground node.
- Make sure that there is electrical continuity between the tube of the Drive Roller and the ground node.
-
Check that the voltage of the power supply unit is correct (23-24VDC) on the main line and for the I/O lines,
and on the single Drive Rollers, nearer and further from the power supply unit, and that the latter is able to
provide a sufficient quantity of current requested by the Drive Rollers in the phase of simultaneous
acceleration and maximum load.
- If a different supply is used between the main supply and I/O, make sure that the 0V-GND of the respective
power-supply units have been connected together.
-
Make sure the VDC supply (both power and signals and I/O) is filtered for possible electrical disturbances or
spikes coming from inductive loads or from VAC systems.
-
NEVER move the Drive Roller by hand to force it to rotate beyond rotation speed or move it by hand when it
is switched off.
- The Drive Roller must NEVER run continuously, so check that the PLC or photocells are coordinated to stop
the Drive Roller when no packages are in transit on it.
- Before starting up the system, make sure that the guards (if specified) have been positioned correctly and
that there are no impediments to normal rotation of the Drive Roller and of all the rollers driven by the Drive
Roller.
-
If the direction of the package on the roller conveyor changes, make sure that the direction changes occur
only when the package is stationary on the roller conveyor.
-
Before the system is delivered, make sure that all the safety systems comply with current legislation and that
they are in perfect working order.
