3.7 RF Bands and Channels
”
. The controller and receiver must operate on the same RF channel to
communicate.
2.4.1 Continuous Transmission
One of the features of an industrial radio remote control system for safety-relevant applications (such as machine
controls) is that it ensures that a permanent connection exists between the transmitting and receiving stations. To
achieve this, the receiver constantly monitors the RF channel to verify that a communication link exists. Should
the receiver not receive valid telegrams, it will automatically turn off, i.e., safety relays and command relays open.
2.4.2 Radio Interference
Signals from other RF-emitting sources might interfere with the radio communication between the controller and
receiver. If the radio link is affected by these sources, it may be necessary to change the RF channel or RF band.
2.4.3 Mounting Location
The controller is supplied with an external antenna. In order to ensure optimum communication, install the
controller and the receiver with line-of-sight between them. Avoid any shielding by metallic constructions. In the
event that the controller must be installed inside a cabinet or building, use a detached antenna and place it
accordingly, and then connect it to the receiver with an adequate coaxial cable.
2.5 System Parameters
The system parameters, including the system address and the selected RF channel, are contained in a
contactless RFID TransKey. This TransKey is easy to swap into a spare unit and is located inside the housing.
The TransKey is pre-programmed by Cattron.
Note: Refer to the separate Configuration Data documents for the specific system parameter settings of
your system.
