•Observe user-specific regulations.
•Only use suitable tools.
•Secure the installation area.
2.5 Operation of OCUs and MCUs with Identical System Address
To ensure safe operation, OCUs and MCUs are paired by way of a system address.
This system address is unique and only assigned once by Cattron.
CAUTION
Conflict of Addresses:
Addresses are never repeated and are System Unique.
The user must ensure that the system address and addressing mode is used as designed.
The system address is marked on the OCU and MCU and must match.
In the event of a breach of this undertaking, the user is liable for any resulting damage/loss and
shall indemnify the manufacturer against all third-party liability claims.
3. Why use Remote Control
Cattron Portable Remote Control (PRC) systems deliver the safety and dependability that are required for efficient
industrial control applications such as overhead cranes, conveyors, machines, etc.
A remote-control system enables an operator to be in the safest, most comfortable and most efficient position for
each operation, thereby minimizing risks of illness, injury or material damage and simultaneously boosting
efficiency and productivity.
4. Remote Control Safety
With an OCU and a matching MCU, a machine such as a crane or vehicle can be remotely radio controlled,
avoiding the need for a wired connection between the human interface and the controlled device. Several different
control elements are integrated into the OCU housing so commands to the device securely encode into a radio
transmission. The MCU is then able to receive this transmission, securely decode these commands, and provide
suitable interfaces to drive the machine.
4.1 Radio Transmission and Security
The transmission between the OCU and MCU is performed by means of a secure RF telegram. Regarding the
actual radio frequency that is used it typically depends on the national regulations and the choice of a licensed or
license exempt frequency band.
A specific RF frequency band and channel may have been selected prior to delivery of the system, depending on
the frequency band, a specific number of RF channels will be available within that band. In all cases a clear
unused (unless timesharing with another Cattron system) channel will be required for reliable operation.
The OCU and MCU must operate on the same RF channel in order to be able to communicate.

9M02-8999-A001-EN
4.1.1 Continuous Transmission
Normally transmission is continuous and the MCU uses this as part of the information required to maintain the
Main Contactor control relays in an active state. If the MCU does not receive a valid telegram in this mode for a
defined period of time, it automatically turns off, i.e. main contactor control relays and command relays open.
Depending on the application, this time varies from 0.5 s to 2.0 s.
Some MCU function relays may be maintained in the absence of communication from an OCU, an example may
be the latched lights function, there are wide range of non-crane type applications that may also continue to run
function relays in the absence of an online OCU.
Note: In order to ensure optimum communication between the OCU and the MCU, the OCU should always
ideally be operated with line-of-sight transmission to the MCU antenna. Try to avoid total shielding of
the signal path by metallic and other solid obstructions.
4.1.2 Radio Interference
Signals from other RF-emitting sources might interfere with the radio communication between the OCU and MCU.
If the radio link is affected by these sources, it may cause intermittent operation and a changing the RF channel
might be necessary.
4.2 Telegram Security
The transmitted telegram contains several security features, as follows:
4.2.1 System Address
This system uses a 24-bit addressing scheme, normally comprising a 16 bit master-address and an 8 bit sub-
address extension, where each OCU/MCU pair shares a common, unique overall address. This address is
contained in every telegram sent by the OCU and is checked by the MCU every time an RF signal is received.
The MCU processes a command only when the address in the telegram matches its own defined address. This is
a safety measure to ensure that the MCU will act only upon its assigned OCU.
4.2.1.1 Addressing Modes
There are multiple addressing modes that may be implemented depending on the specific application needs,
these are;
TSAC mode = 16 bit Master Address (MA) and 8 bit Sub Address (SA), creating one single 24 bit address.
e.g. OCU address = 0000 0000 0000 0001 0000 0001
MCU address = 0000 0000 0000 0001 0000 0001 (MCU Online matching MA plus SA byte)
equivalent to a 24 bit address.
This mode enables an OCU to select one of up to 255 MCUs (and request a Talkback™ message from that
MCU).
BSAC mode = 16 bit MA and an 8 bit SA where each bit of the SA represents one of 8 possible MCUs.
e.g. OCU Address = 0000 0000 0000 0001 0100 0101
MCU 1 Address = 0000 0000 0000 0001 0000 0001 (MCU Online matching MA plus SA bit)
MCU 2 Address = 0000 0000 0000 0001 0000 0100 (MCU Online matching MA plus SA bit)
MCU 3 Address = 0000 0000 0000 0001 0100 0000 (MCU Online matching MA plus SA bit)
equivalent to a 17 bit address.

411, 611 & 325 OCU
User Manual

9M02-8999-A001-EN
This mode enables an OCU to simultaneously select between 1 and 8 MCUs (and request a Talkback™ message
from any of those MCUs).
ESAC mode = 8 bit Master Address and a 16 bit Sub Address where each bit of the sub address represents
one of 16 possible MCUs, this mode is only used in limited and controlled circumstances due to the reduction in
total effective telegram addresses.
e.g. OCU Address = 0000 0001 1000 0000 0100 0101
MCU 1 Address = 0000 0001 0000 0000 0000 0001 (MCU Online matching MA plus SA bit)
MCU 2 Address = 0000 0001 0000 0000 0000 0100 (MCU Online matching MA plus SA bit)
MCU 5 Address = 0000 0001 0000 0000 0001 0000 (MCU Offline because there is no matching SA)
MCU 16 Address = 0000 0001 1000 0000 0000 0000 (MCU Online matching MA plus SA bit)
equivalent to a 9 bit address.
This is an extension of the BSAC mode that enables an OCU to simultaneously select between 1 and 16 MCUs
(and request a Talkback™ message from any of those MCUs).
4.2.2 CRC
The telegram is checked for integrity using a 16-bit CRC, corrupted frames will be rejected because the
recalculated CRC will not match the transmitted CRC.
4.2.3 Session and Frame Security
Each message is protected by an enhanced proprietary security protocol in such a way that every telegram sent is
both encrypted and unique, thereby eliminating any possibility of a ‘hacking’or ‘store and replay’attack from ever
being successful.

4.3 Firmware Features
Firmware enables the safe core functionality of the OCU and MCU, additionally it is the resident firmware ‘Apps’
within the firmware in conjunction with the related Configuration Parameters that enable the OCU and MCU to
implement specific functionality such as Hoist Select, Crane Select, Pitch and Catch, Motion interlocking,
Talkback, RFID Security and RFID re-configuration, etc.
Firmware is upgradeable over the Bluetooth™ link, this is a closed box operation.
4.4 Configuration Parameters
The configuration parameters, including the System Address, Sub-Address and Addressing mode, the selected
RF channel(s), and those parameters needed to enable programmed function to operate much more are initially
programmed over the Bluetooth™ link, that is a closed box operation.
Configuration parameters may also be selected when programmed to do so by interaction with such items as an
RFID tag.
5. System Overview
Each system typically includes one or two OCUs and one MCU plus accessories, but other combinations of OCUs
and MCUs are possible.
Additionally, systems may operate independently or in combinations that allow for example tandem control.
MCUs are available in with differing interface formats such as Relay, Safety relay, CAN, Ethernet etc. and can be
paired with these OCUs.
An MCU can be considered as a specialized Safety PLC.
Currently the 411, 611 and 325 OCUs can be used with the 10R or 17R MCU, this portfolio and the possible
combinations will be continuously expanded.
These OCUs are not backward compatible with older Remtron™, Cattron™ or CattronControl™ MCUs because
they have a high security, Enhanced Black Channel RF telegram format, that has become necessary to prevent a
remote control system being subjected to a ‘Store and Replay Attack’, the possibility of which has been made
more likely by the proliferation of lower cost RF scanning equipment.
The OCU and MCU are linked by this secure communication system and the MCU drives the machine interface
(relays, etc.). Therefore, the machine is under the direct control of the OCU and hence operator.
The system is available as a range of standard packages that fit most applications but can also be tailored to any
custom application, this provides a great deal of flexibility to make the solution exactly fit your needs.
Standard Systems configurations, and other media are available on the www.Cattron.com website under the
specific product resources tab.
These systems feature an ability to wirelessly connect to the OCU or MCU and upgrade firmware to take
advantage of new features as they are released as well as the ability to wirelessly change configuration items
such as frequency, address, function, interlocking, hoist crane select, SymmetryLock™, or examine function
totalizers, data and error logs etc.

6 OCU Overview
6.1General
These OCUs are globally compliant when supplied with an appropriate radio module for the region being used, for
non-standard applications additional regional or application specific certifications may be required. These units
have been designed with the latest generation safety electronics and firmware and exceed the safety related
systems requirements for ISO13849 Category 3 PLd for the stop function and when configured with specific
options, also for defined control functions.
OCUs are equipped with two internal antennae, one for 2.4GHz and the other for the sub-GHz link, the typical
operating range while dependent on the local environment is well in excess of 300 ft, with an open site
performance in excess of 750ft can be expected.
Should the OCU exceed the operating range and the signal be lost, all motions on the controlled machine will
cease.
OCUs have been approved to comply with the RF standards applicable to the region or country of use, there are
license exempt bands and license required bands.
In North America, the 915MHz band is license exempt (FCC Part 15 and Industry Canada RSS-210 standards).
In Europe and other regions, the typical license exempt band is 433-434 MHz, 869MHz; again, other licensed and
unlicensed frequency bands are available.
Globally the 2.4GHz band is generally available as license exempt with some technical variations.
The use of licensed bands including 450-470MHz will require an operating license but provide additional reliability
because they are protected from interference.
The OCUs are designed to be powered by two off the shelf AA batteries for the quoted 95 hours of nominal
operation (depending on configuration) and while the OCU would work with NiMH rechargeable batteries the
battery life monitoring would not be accurate and may lead to unexpected shutdown.
Status and feedback are provided by 6 LEDs and a Haptic vibration motor, the 6 LEDs are Status, Stop, A, B, 1
and 2; Status is a Tri-color, Stop, A, B, 1 and 2 are Bi-color, there is an ambient light sensor to adjust the intensity
based on background light levels.
The Stop LED shows the current availability of the Stop switch in line with the latest standards.
LEDs A, B, 1 and 2 located to the right and left of the ‘STATUS’ LED may be configured to indicate when an OCU
function command such as hoist select, or to provide status indication of machine state, via Talkback.
A Force Sensor provides continuous monitoring of OCU and freefall will safely blank functions if the OCU is
dropped. High G shock is logged to monitor for equipment abuse.

6.2 OCU Types Overview
The Remtron 411, 611 and 325 OCUs are lightweight, palm-sized, extremely rugged controllers that are available
in standard and customized configurations.
Each OCU is designed to meet a specific control application. Two housing sizes are available that are fitted with
the three switch layouts seen below
A label insert sheet is provided to identify button functionality to suit most applications, and while the front graphic
is standard, it is possible to have both customized graphics and customized switch configurations.
Figure 1: 411, 611 and 325 OCUs, front view
The ‘STATUS’ LED (located center top) indicates the operational mode and any error messages.
The aperture directly under the ‘STATUS’ LED is an ambient light sensor that is used to adjust LED intensity and
improve battery life.
The four remaining LEDs, A, B, to the left of the Status LED and 1 and 2 to the right of the Status LED, indicate
either selection such as hoist or crane select, information or optional Talkback information.
There is a Haptic (vibration) feedback motor within the case to provide alerting and confirmation to an operator
focused on the task at hand.
A high reliability switch system is provided and the rocker switches of the 411 and 611 are single step while the
rockers of the 325 are dual step, the other auxiliary buttons are single step. The Stop switch is unique and
features a Cat3 safety architecture and incorporates LED back lighting to provide information on the Stop switch
availability as per latest standards.

9M02-8999-A001-EN
Each function pushbutton or rocker switch may have one or more steps as described above, these can operate
different functions. Typically, on a two-step rocker the first step controls a direction or function and the second
step controls a speed increment, although it is possible with a step-less drive to use the second step as
accelerate, the first step as hold speed, and the released state as decelerate.
Additionally for a high safety function it is possible to use both the direction and speed step as a CAT3 PLd input.
Any function is normally active only if the respective pushbutton is pressed. When the pushbutton is released, the
function automatically stops, however latched MCU functions may be defined for functions such as Lights that
need to be maintained in the absence of an online OCU.
The Start push button is for System Start / Mainline reset and / or HORN depending on machine wiring.
At startup the pushbuttons are checked for the correct off state.
These OCUs use off the shelf AA Alkaline batteries that will typically provide around 95 hours of continuous
operation, the batteries are accessed via a sealed cover retained by two screws as shown below.

6.3 RFID Reader
These OCUs have an additional feature option of a 125kHz RFID reader that can be used in two primary modes
1. User Authorization; where the user needs to hold the OCU to an ID badge at start up to be able to select
an operational mode. This means that an OCU can associate an ID badge identity (person) to a specific
machine and a specific set of available commands, or if no match is found not be able to start the OCU.
2. OCU Configuration to match a specific machine; where the user needs to hold the OCU to an ID TAG
located on or near a machine at start up, to be able to select that specific machine. This means that an
OCU can be owned by one user but used freely to control many different machines.
These two are similar and both required a database that cross references either Authorized User identities or
Machine Identities to a specific System Address and set of configuration parameters. This database is then
loaded into the OCU and used at startup.
6.4 Data Logging
These OCUs feature a fault and data logging capability that provides users with the ability to diagnose
any intermittent operational issues and records the total switch activations for planned maintenance of the
OCU.
The Associated MCUs feature enhanced logging capabilities with totalizers and run time per motion that
enable planned maintenance and data-analytics.
The OCU logs specific data as shown in the table below, the MCU has extensive data logging that goes
beyond this data set.
Data log events and switch totalizers can be downloaded over a Bluetooth link using the Configuration PC
tool.

Ensure that the OCU being used is the correct one for the machine to be controlled, an OCU may operate
equipment that is many hundreds of feet away. Each system is assigned a unique address, the OCU and MCU
both use this address and it is not normally duplicated, the OCU should have a label on it identifying the machine
to which it is assigned.
WARNING
More than one remote control system may be used at, around, or nearby your operating facility.
Therefore, before selecting an address for a system or spare you must ensure that it is the correct
address for the desired equipment to be operated.
If the wrong address is programmed into an OCU or MCU, other remote-controlled equipment
located at, around, or nearby your facility may unintentionally become operational.
Failure to comply with the above warnings may result in serious injury or death to personnel and
damage to equipment.
7.4 Operating the OCU
7.4.1 Momentary Transmission Mode
For systems configured in the Momentary Transmission (MT) mode, the OCU will (assuming no faults and good
battery) transmit the STOP command from the OFF, Passive or Active States but will not transmit command
functions until the Start sequence (STOP / START) has been completed. The OCU will continue to transmit for 5
seconds after any command button has been released or the stop switch has been pressed, then cease
transmitting. The LED and Haptic indications for Stop being pressed in Sleep or Passive mode are no different to
those shown in the following paragraphs.
WARNING
Momentary Transmission (MT) mode should not be used where it must be guaranteed that the
OCU will be able stop the machine, for these applications a continuous mode of transmission must
be used. Additionally, in MT Mode the MCU main contactor control safety relays can be configured
to stay turned on for varying lengths of time including infinite, or until the OCU has commanded
them to turn OFF.
MT should only be used where a risk assessment has indicated that this mode of operation
presents no additional risk.
In MT mode there is no guarantee that when an OCU button is pressed it will manage to
communicate with the MCU.
Failure to comply with the above warnings may result in serious injury or death to personnel and
damage to equipment.
7.4.2 Transition to Passive Mode
From an OFF state the OCU can be powered up by pressing the START button, this will wake the OCU from a
deep sleep state to a fully tested PASSIVE mode where it is waiting for user input to move into another
operational mode.
The LEDs and Haptic will be tested at this point so you will see all LEDs flash briefly and the Haptic buzz to
confirm they are all working.
The center Status and Right-hand LEDs 1 & 2 will then illuminate, the battery status will be shown on LEDs 1 & 2,
after a few seconds LED1 & 2 will turn back OFF.

7.4.3 Transition to Active Mode
From Passive Mode the OCU can be moved into Active (Transmitting) mode, this stage involves some critical
Safety tests and a positive transition into active machine controlling mode.
The STOP switch has two contact elements under it, and they are tested every time the OCU is moved into an
Active mode, additionally all switch elements are tested at this phase to ensure that none of them are activated,
the start sequence from Passive Mode is; Press the Stop switch and then press the Start switch within 3 seconds.
Table 4 Active Mode LED Sequence
At this point the OCU is operative and the target machine will be under direct control, verify the connection by
activating a non-motion function such as the Horn button.
Test all functions briefly at the start of the work session.
WARNING
Before attempting to use the system, verify the target crane or machine you wish to operate is
under the direct command of your OCU. This is accomplished by operating a non-motion OCU
function such as the horn and observing that the horn sounds on the targeted crane or machine.
Failure to implement the above may result in serious injury or death to personnel and damage to
equipment.

7.4.4 Transition to Passive Mode
The machine may be brought to a halt at any time by simply releasing the motion control button that will
deactivate the motion control, or in an emergency pressing the STOP button that will typically deactivate the
crane main contactor as well. When the STOP button is pressed the OCU sets the STATUS LED Red and the
ESTOP LED Green and sends a positive stop command to the MCU and then terminates transmission, both of
which will deactivate all commands and de-energize the crane main contactor.
From this stage the OCU can either be transitioned back to Active mode of switched off.
7.4.5 Transition to OFF Mode
From Passive mode the OCU can either be left until it powers down automatically, or manually put to sleep by
pressing and holding the STOP button for 3 seconds.
7.5 Control Functions
The system will have been configured in one of many different standard configurations or possibly a custom
configuration, there will be a configuration sheet that identifies all the functions in detail; some of the specific
functions are mentioned below.
7.5.1 Magnet/Vacuum Lift and Drop
Lift is always a single button function whereas drop is always a two-button function for safety, depending on the
number of available auxiliary buttons, the DROP may either be a separate button or combined with LIFT.
7.5.1.1 Separate DROP
To Drop press LIFT and DROP together for 3 seconds, release LIFT and then release DROP.
7.5.1.2 Combined DROP
To Drop press LIFT/DROP and ON/ALM together for 3 seconds, release LIFT/DROP then release ON/ALM.
7.5.2 Hoist or Crane Select
This function enables successive selection of two hoists or two cranes, typically by pressing one button on the
OCU.
The sequence typically is set to default to ‘no selection’ at switch on and each press of the button increments
around a loop of; no selection, A, B, BOTH, no selection etc.
Confirmation of the actual selection made is shown on the A, B, 1 and 2 LEDs on the top of the OCU.
It is necessary to press the select button for longer than 500mS to ensure positive selection.
7.5.3 Lights
Lights or latched function selection is an MCU based variation where the relay being Latched toggles between the
OFF and ON state and it is not affected by the state of the MCU Mainline Contactor relay outputs, i.e. when the
MLC relays turn off, this assigned relay will stay in whatever state it was, OFF>OFF or ON>ON. The state can
only be changed by turning the OCU back on and changing the state or resetting the MCUs power.
This prevents an area light on a crane automatically turning OFF when the remote is turned off.
7.6 RFID Option
These OCUs have an additional feature option of a 125kHz RFID reader that can be used in two primary modes

9M02-8999-A001-EN
1. User Authorization; where the user needs to hold the OCU to an ID badge at start up to be able to
select an operational mode. This means that an OCU can associate an ID badge identity (person) to
a specific machine and a specific set of available commands, or if no match is found not be able to
start the OCU.
This mode has an associated database of users that have specific rights, the OCU will either allow or
deny a user to transition the OCU into Active Mode, additionally a user may call up a specific pre-
programmed configuration, so for instance a maintenance supervisor will be given additional control
functionality not available to the normal user.
After a successful RFID Badge read if the OCU is powered OFF, the process will need to be repeated
the next time it is powered ON.
2. OCU Configuration to match a specific machine; where the user needs to hold the OCU to an RFID
TAG located on or near a machine at start up to be able to select that specific machines MCU. This
means that an OCU can be owned by one user but used freely to control many different machines.
This mode also has an associated database of machines MCU and associated characteristics, the
OCU will call up a specific pre-programmed configuration such as frequency, address, button
functionality and any additional required functions.
7.6.1 Transition to RFID Read Mode
From Passive mode the OCU can be transitioned to RFID read mode by pressing and holding the ON/ALM
button for 5 seconds. If the OCU is held to a pre-assigned Personnel ID card or Machine Tag, the OCU will
attempt to read the RFID device and set the appropriate parameters. After a successful read the OCU will
revert to Passive Mode.
