2. Radio Remote Control Controller
2.1 General
The radio remote control controller connects over its interface to external actuators in order perform the following
functions: cyclically read the status of these actuators, transform this data into a serial data string, form a telegram
by adding system relevant data, and transmit this telegram via a RF signal to its corresponding receiver.
2.2 SCU32 Controller
The SCU32 controller allows the transmission of up to 32 + 4 digital commands. The controller interface to the
external actuators is realized by an optocoupler interface board, providing a galvanic isolation and protecting the
microprocessors against overvoltage damage by the external signal source.
Figure 1: SCU32 Controller with Han Connector
2.3 System Address
In an industrial radio remote control system, each controller/receiver pair shares a common, unique system
address. The system address is contained in every telegram sent by the controller and is checked every time a
RF signal is received. In order for the processors in the receiver to activate a command (relay), the system
address in the telegram and the system address stored in the receiver must match. This is a safety measure to
ensure that the receiver interacts only with its assigned controller.
CAUTION
Conflict of Addresses
•The operator must ensure that the system address is used for a single pair of controllers and
receivers.
•If more than one receiver or controller is used to control a machine or system, the operator
must take precautions so that only a single controller operates at each time.
•In the event of a breach of this undertaking, the customer or the operator, respectively, is
liable for the resulting damage/loss and they shall indemnify the manufacturer against all
third-party liability claims.
2.4 Radio Transmission
The transmission between the controller and receiver occurs through radio communication. With regard to the
actual radio frequency being used, there are several radio frequency bands available. Within the respective
frequency band, a specific RF channel must be selected. Depending on the frequency band, a certain number of
RF channels are available. For details regarding the available RF channels, please refer to Section 0, “

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.

DANGER
Hazardous Voltage
Disconnect the machine or the system from the power source before installation, and ensure that
it cannot be switched on unintentionally.
Installation and maintenance must be carried out by trained personnel only.
3.1 Mounting
Mount the Control unit using the accessories included. For mounting details and options, refer to Section Error!
Reference source not found., “Error! Reference source not found.”.
3.2 Electrical Connections
For all electrical connections, such as the power supply including the ground (PE) and command inputs, refer to
the separate electrical drawings received with the delivery of the system. Connect the unit according to these
drawings.
CAUTION
Wiring and hazard of short circuits within the housing
•Ensure the wiring is connected so that the wire ends are securely attached and without bare
conductors; the use of crimps is recommended.
•Ensure that wires are suitably supported and routed through suitable strain relief bushings
where needed.
•Ensure that a suitable protective earth (i.e., a ground wire/rod) is connected to the OCU PE
terminal.
•If any rigid metallic conduit is used, it must be connected to a suitable protective earth.

3.2.1 Optocoupler Input Voltage
The interface to the external digital actuators is achieved with optocouplers that incorporate overvoltage
protection. The nominal voltage to switch the optocouplers is 12/24 VDC. This voltage can either be supplied
externally into the receiver, or via the internally-available power supply.
3.3 External Antenna (standard)
The controller usually includes an external RF antenna attached the receiver housing. Ensure that the controller is
installed in a location where line-of-sight exists with the receiver, and that the system does not exceed the
maximum distance between the units.
3.4 Detached Antenna Kit (optional)
If the controller is supplied with an antenna kit to install the antenna detached from the receiver housing, install
the antenna in a suitable location following the supplier's instructions. Run the coaxial cable from the antenna to
the controller and connect it to the external antenna connection point. Ensure that the coaxial cable being used
does not exceed the maximum allowable attenuation for your application, as this might reduce the range of the
system.
3.5 TransKey
Verify that the controller TransKey (black) matching the receiver TransKey (yellow) is placed in the appropriate
holder inside the controller enclosure. Each TransKey pair is marked with a unique system address.
Figure 4: TransKey Pair (Rx + Tx)
Note: Do not interchange the TransKeys for the controller (black) and the receiver (yellow). If the
TransKeys are interchanged, the system will not operate.
3.6 RF Channel Selection
In order to ensure interference-free radio control system operation, choose an undisturbed RF channel. Since the
RF channel is typically set by the manufacturer, it should be determined before shipping the system to the
customer’s site.
3.6.1 Changing the RF Channel
Due to interference from other systems, it may be necessary to change the RF channel preset by the
manufacturer. The RF channel can be changed by reprogramming the TransKey. This is typically done by the
manufacturer or can be done on-site with an appropriate programming adapter and software.
Note: When changing the RF channel, be sure to observe the country-specific regulations regarding
frequency range and channel.
