TECHNICAL MANUAL FOR THE RDR BL3 - V1.1 DRIVE ROLLER Rev. 21/09/2018 page 26
9 CONNECTING THE DRIVE ROLLER
9.1 General
The RDR BL3 Drive Roller has a multicore ROHS cable marked Rulmeca Drive Roller that can withstand maximum
temperatures up to 105 °C and voltage up to 300 volts.
In the standard version, the Drive Roller connecting cable has a 5-core connector at one end.
If requested, the Drive Roller can be supplied without the connector.
For wire specifications, see table below.
Pin Wire colour Function
Wire section
mm2
Pin 1
Red Power 24 Vdc 0.34
Pin 3 Blue Power supply 0V-GND 0.34
Pin 5 Yellow Operation - speed 0.14
Pin 2 Green Direction of rotation 0.14
Pin 4 Black Fault signal (output) 0.14
Connect the BLUE (0V) and RED (24Vdc) wires with a larger section to a power supply unit with a current that is
sufficient for the number of Drive Rollers that are powered simultaneously and for their absorbed current at
maximum loads.
The Drive Roller is protected against accidental power supply polarity reversal to ensure safe and risk-free wiring.
WARNING:
- If a PLC or external signals are used, the 0V-GND lines of the power supply unit of the Drive Rollers
and the 0V-GND of the PLC or the external signals must be connected together.
- Check that there are no spikes above 32 VDC in the 24 VDC supply to the Drive Rollers and its
command signals. If necessary, filter the sources of these spikes (remote switch coils, relays, VAC
motors etc.).
- If the 24 VDC power supply line is very long, check that the voltage at the heads of the most distant
and near Drive Roller is around 24 VDC and within the permitted 18 and 26 VDC with the load of all
the Drive Rollers connected and operating. If necessary, adjust the voltage of the power supply unit,
increase the section of the cables and/or connect to a closed loop the line supplying power to the
Drive Rollers.
-
In case that the Drive Roller fault output is not connected (not recommended) will be lost only the
evidence of malfunctioning status.
- The Drive Roller can work even without the Fault output connection. Still remaining the thermal and
overcurrents protections.
