Introduction
This document contains minimum information that is necessary to properly install the device and to
perform its initial testing. Full description of the controller has been included in the general
user guide for the PRx11 series controllers, which is available at www.roger.pl.
The controller can be programmed manually or with a PC. Connecting the controller to the PC
requires utilization of the relevant communication interface (UT-2, UT-2USB, UT-4 or RUD-1)
however the RUD-1 is most suitable for this purpose because provides 12V DC output which can be
used to supply programmed device. Manual programming can be performed locally using the
device’s keypad (PR611 only) or using an additional, PRT series reader connected to the main
PR611/PR621 controller unit (the reader connected to programmed controller should be equipped
with a keypad and configured to “RACS mode address ID0”). Later, for device’s programming a so
called
Programming Cards can be used. Programming Cards are standard proximity cards which
were assigned specific programming functions. Programming Cards can be defined during device’s
configuration process.
Note: The PR611/PR621 require the PR Master 4.3.1 or higher.
Controller Installation
The controller can be installed both inside and outside of buildings and does not require additional
protections against rainfalls (snowfalls) as well as humidity. All the electrical connections can be
done only when the power supply is disconnected. The new, factory-made controller, has the
address ID=00 and is equipped with the programmed MASTER card delivered with a new device. The
card can be used for the initial testing of the device after the installation.
All the devices connected to the AC system’s RS 485 communication bus should have the common
minus (GND). In order to ensure this, all the GND terminals of power supply units used in the
system should be connected together with the separate wire. The other solution is to individually
ground (connect to earth) each of GND terminals. However, the latter solution is not recommended,
because when grounding potentials in different locations of installation are not the same, the
equalizing current will flow through the system’s power supply lines. That in turn, can cause
disruption of system work or even its damage.
Readers can be installed on metal surfaces but in such cases the reading distance reduction should
be expected. The reading distance reduction effect can be minimized by installing readers on the
non-metal plate spacer. The thickness of such spacer should be at least 10 mm. The distance
between two proximity readers should not be less than 0.5m. In case the two readers are mounted
on opposite sides of the same wall it is recommended that they not create the same geometrical
axis. If this is not possible, a metal plate beneath each of the readers should be installed.
Additionally, between each reader and the plate the non metallic spacer of minimal 10 mm thickness
should be put.
The controller is equipped with 6 installation holes in bottom of the enclosure. The distance between
two of them placed horizontally is 60 mm, which make it possible to install the device in the
standard flush-mounted gang box.
Note: Under no circumstances the positive terminals of the power supply units in the system would
be connected together. The note applies also for the supply leads available in controllers with its
own power supply (e.g. PR411, PR402).
Address Setting
Before the controller is connected to the communication bus of the RACS, the unique address (ID
number) should be assigned to it. A new address setting can be performed during the Memory
Reset procedure or from the PC with managing program. In order to change the address from the
PC, the controller should be connected using the communication interface (UT-2, UT-2USB, UT-4 or
RUD-1) however the most preferred is RUD-1 which provides 12V CD output to supply the
programmed unit. Then the controller should be find using PR Master program, and finally its
destination address should be assigned. The RACS 4 supports addresses from the 00–99 range.
