Leuze electronic RFU 61 Notes For Installation And Setting Up

Notes for Installation and Setting up
RFU 61/ RFU 81and IMRFU1
Mounting and installation
Please note we recommend a mounting angle between reader (RFU) and
conveying system of 15-45° . an additional angle of 15° to the horizontal line
helps avoiding reflections. The connection between reader and controller box
IMRFU1 should be done with a 4-wire cable (>10m length shielded). Further
notes you find in the manuals.
RFU 61/ RFU 81 and IMRFU1 with Leuze multiNet at MA 21 100.2
Installation
For RS 485 networks it is important to avoid A-/B-wire interchanges. A separat
network ground line is recommended, too. The shield should be connected
only on one side. At the last slave in line, the network has to be terminated by a
220 Ω Ω Ω Ω resistor. After mounting the RFU and MA, turn the address switch of
each MA 21 100.2 to the dedicated address and set DIP-switch 1 to ON
(„Transparent-Mode"), for network operation set DIP-switch 3 („Service") to
OFF. At the multiNet master (MA 31) the total number of slaves has to be set.
Before switching on the power supply please check the wiring.
Setting Up
When the firmware is started, the MA 21 and the RFU give a ready sign on the
network with „XXs" (XX is the slave address). The parameter setting can be
done either with each device via Service interface or via multiNet master and
the slave address in front of the command („01V"). If all slaves should be set to
the same parameters, you can set a"00B" in front of the parameter string and
send it to the master device. After the setting of the parameter, please make
sure that all DIP switches are set to „HOST„ („operation").
For more details concerning the MA 21 please see the technical manual of the
MA 21.

Remedy
1- Check wiring and correct it, if
necessary install 220 Ω Ω Ω Ω resistors at
end of line
2- Set Number with switch in master
device (MA31)
set
3- Set DIP switch 3 to HOST/ OFF, DIP
switch 4 to BCL/RFU / ON
On Service interface MA 31 with
terminal use command „00BV"
to check Slaves
MA 21: Set DIP 1 and 4 to ON
RFU: Restart with „00BH" command on
