3. General

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. A number of

different control elements are integrated into the OCU housing so that commands to the device are securely

encoded 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.

3.1 Radio Transmission

The transmission between the OCU and MCU is performed by means of radio communication. With regard to the

actual radio frequency that is used, there are several radio frequency bands available. A specific RF channel must

be selected within the respective frequency band. Depending on the frequency band, a certain number of RF

channels are available. For details regarding the available standard RF channels please refer to the Channel

Tables and Technical Data sections of this document. Other frequency bands may be designated and deployed.

The OCU and MCU must operate on the same RF channel in order to be able to communicate.

3.1.1 Continuous Transmission

Typically, transmission is continuous and the MCU uses this as part of the information required to maintain the

safety relays in an active state. If the MCU does not receive a valid telegram in this mode for a certain period of

time (defined as PNH-Time), it automatically turns off; i.e., safety relays and command relays open. Depending on

the application, the PNH-Time varies from 0.5 s to 2.0 s.

In order to ensure optimum communication between the OCU and the MCU in this mode, ideally operate the OCU

with line of sight to the MCU or its antenna at all times. Avoid total shielding by metallic obstructions.

In certain other configurations, the MCU may be enabled to operate without loss of safety in the absence of an RF

signal, much as a safety PLC will do. Such applications are strictly defined.

3.1.2 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, changing the RF channel or even the RF band might be necessary.

3.2 System Address

In an industrial radio remote control system, each OCU/MCU pair shares a common, unique system address. This

system address is contained in every telegram sent by the OCU and is checked by the MCU every time a RF

signal is received. The MCU processes a command only when the address in the telegram and the address

stored in the MCU match. This is a safety measure to ensure that the MCU will act only upon its assigned OCU.

The system address is stored in the TransKeys; please see Section 0.

Figure 2: OCU TransKey (black)

10



3.3 System Parameters

The system parameters, including the system address and the selected RF channel, are set by programming the

TransKey. This is a removable radio frequency identification device (RFID) located inside the OCU and MCU. It is

programmed by the manufacturer.

Note: Please refer to the separate 'Configuration Data' documents for the specific system parameter settings

of your system.

4. OCU

4.1 General

The LRC OCU is versatile and can be highly customized to meet the operational requirements of many different

applications. For this, a variety of control elements (joysticks, paddles, push buttons, switches, etc.) are available

to tailor an OCU layout for the individual application.

Note: For the system-specific OCU layout for your application, please refer to the separate engineering

drawings you received with the delivery of the system.

Figure 5: LRC-M1 with LCD

4.2 Display Option

The OCU can be optionally equipped with a graphic display. This can be used to indicate certain OCU parameters

such as the operating frequency, internal error messages and battery status, and/or to display feedback data that

transmits back from the corresponding MCU (in this case, it functions as a transceiver, receiving and transmitting

data). For further information regarding the feedback option, please refer to the system-specific information

provided with your system.

4.3 Before Turning On

1. Verify that the TransKey (black) is placed in the TransKey hollow inside the battery compartment.

2. Insert a fully charged battery.

Note: Batteries are shipped uncharged.

4.4 Turning the OCU On (Standard)

1. Release the STOP switch and ensure all motion controls including joysticks are at neutral.

2. Turn the key switch to the ON position 'I'.

3. The Status LED briefly lights red, then flashes green.

4. The OCU is turned on.

Note: After the OCU is turned on, the safety relays in the MCU energize and the MCU is able to respond to

commands initiated by the OCU.


13


4.5 Turning the OCU On with STOP Switch Verification

(this feature is only made available if requested at time of order)

The OCU can be configured so that in order to turn on the unit, the STOP switch must be activated once before

the OCU goes into operation.

1. Release the STOP switch and ensure all motion controls including joysticks are at neutral.

2. Turn the key switch to the ON position 'I'.

3. The Status LED lights red.

4. Activate the STOP switch (the Status LED lights orange) and then release within 10 seconds.

5. The Status LED flashes green.

6. The OCU is turned on.

Note: After the OCU is turned on, the safety relays in the MCU energize and the MCU is able to respond to

commands initiated by the OCU.

4.6 Turning the OCU Off

1. Turn the OCU off by bringing the key switch into the '0' position.

Note: After the OCU turns off, the safety relays and all other relays (in the case of a relay interface) in the

MCU de-energize and the MCU is unable to respond to any commands initiated by the OCU.

In certain application, the MCU can optionally be configured to operate as a safety PLC and continue to

control the machine in the absence of an online OCU. Conditions will be strictly defined.

4.7 STOP Command

In the event of a dangerous situation, a STOP command can be initiated by pressing the STOP switch.

1. Press the STOP switch.

2. MCU turns off.

3. OCU turns off.

Note: After pressing the STOP switch, the safety relays and all other commands in the MCU de-energize and

the MCU is unable to respond to any commands initiated by the OCU. The OCU unit is turned off.

4.8 Status LED

The status LED indicates the operation mode and error messages.

Table 1: Status LED Indications

Status LED Condition Corrective Action

Flashes green at 2.0 s intervals Normal mode No action required

Flashes red at 2.0 s intervals Error indication Refer to Section 9: Troubleshooting

5. Features

5.1 Automatic Turn-Off

The OCU turns off automatically when the following events occur:

• Battery discharge protection (battery low)

• Auto Off timeout expires (pre-set between 30 seconds to 30 minutes)

• Internal failure (hardware or software)

5.2 Enable / Push to Operate (PTO) Switches

Push to Operate is an optional feature that requires the user to press a switch before a function or set of functions

are made active. This can be applied to any controller and is implemented in the MCU software.

When a switch must be pressed down while the joystick is in use, operators may find it physically demanding. For

this reason, the PTO button is normally used as an enable to start the motion; that is, the button must be pressed

before a motion is activated, but once the motion is active the button does not need to be maintained. Once the

motion is returned to neutral, there is an approximately 2 second delay (during which the motion can be

reactivated) before the button once again has to be pressed.

Often, a client will choose not to use the buttons at the end of the joysticks, but instead use a button or toggle on

the controller that must be pressed just before commencing to activate a motion. It achieves the same goal but

typically at lower cost.

Because it is used in logic, the enable function on a joystick, button, or toggle can be used to enable any single or

set of functions on the controller.

5.3 Vigilance

The Vigilance function is an optional feature and is another method of maintaining the system in an active state; it

is available for any LRC controller.

This method requires the operator to repeatedly activate a switch before a software timer expires.

As an example, an operator may be required to activate a toggle switch every 30 seconds or less. If the operator

fails to reset the toggle switch, a warning is issued for 10 seconds. During this period the operator can still reset

the vigilance function, but if this period times-out without resetting, the OCU shuts down.

The Timeout time is configurable for any time between 1 second and 11 minutes, in 1 second increments.

The Warning period is configurable between 0 and 59 seconds.

Note that this feature is more closely related to machine and vehicle operation than crane use.

5.4 Tilt

The Tilt function is an optional feature and a safety function designed to shut down the OCU if it is tilted (for

example, if an operator falls over). It is available for any LRC OCU.

The Tilt angle may be configured for angles between 30 and 60 degrees in 5 degree increments.

The Tilt time delay (the period for which the unit can remain tilted before a penalty) is configurable between 0 and

30 seconds. During this period the OCU issues an audible warning of impending penalty.

15



There is a Tilt time extension that can be configured, if required, that allows the operator to extend the tilt time by

another configurable time of up to 30 seconds.

Typically, the tilt settings are configured so that if an angle greater than 45 degrees is exceeded for more than 5

seconds, the unit shuts down.

If an operator has some process where he does bend over, the Tilt time extension is added and set for 30

seconds to allow the process to be completed without a penalty.

Note that this feature is more closely related to machine and vehicle operation than crane use.

5.5 IR Enable

The IR Enable function is an optional feature.

This feature requires the OCU to be taken within a closely defined zone of coverage from an IR (infrared)

transmitter before the OCU can be enabled.

The enable zone is typically used to ensure that an OCU is not switched on before an operator has moved into a

region where it is safe to operate the crane or machine. Specifically, it ensures that the OCU cannot be enabled

when it is away from a crane or machine. An example of this function is to prevent a situation whereby the OCU

radio can communicate through walls to the crane or machine, but it is inadvertently operated in an adjacent room

such as a cafeteria or maintenance workshop.

The IR transmitters shown below are mounted either singly or in multiples as required to achieve the required IR

coverage zone.

Figure 6: IR Enable Components

The IR beam is specifically encoded to address only the target system and is fully secure.

The OCU has an IR sensor mounted on it and the LRC-M and LRC-L can have the sensor in any location. The

product shown above right has the sensor to the right of the Stop switch.

16



5.6 Delayed Shutoff

The Delayed Shutoff function is an optional feature.

Delayed Shutoff enables a controlled OCU shutdown mode that allows a user to switch from remote operating

mode to a local operating mode without the machine going into a shutdown.

For example, this allows a diesel engine driven hydraulic machine to continue to run for this short transfer period

rather than the operator going through a machine/engine start sequence to get it back into manual mode. This is

typically required when the OCU is left in a storage location remote from the vehicle cab; one example may be

use in underground mining machines.

In this mode, an OCU remains active for a predefined time delay between 30 seconds and 5 minutes after the

ON/OFF switch turns off. During this “DSO period”, all OCU controls are disabled except for the STOP and TILT

functions.

The OCU turns off when one of the following events is true:

• The DSO period expires

• The STOP button is pressed

• A TILT event occurs (if configured)

5.7 User Authorization

The User Authorization feature is an option for LRC-M and LRC-L OCUs.

This feature requires the system to be enabled by the insertion of an ID card into a receptacle on the OCU. This

receptacle reads the card and compares the ID card to a list of pre-defined users. If the card is current, the OCU

sends a signal to the MCU that the user is authorized and enables control.

5.8 Multi Address Capability (MAC)

MAC is an optional feature and allows up to 15 MCUs to be controlled by up to seven OCUs.

Some simple examples are below; each MCU is equipped with a number of lights outputs to indicate the current

status.

Multi Control Mode Single Control Mode

Figure 7: MAC Configurations

17



REQUEST Function

MCUs are requested by an OCU. This is performed using a separate Request button in conjunction with the

position of an MCU selection on the OCU. The selection can be linked to one or more MCUs.

LRC OCUs have a rotary MCU selection switch.

All of the MCUs assigned to a selected switch position are always requested together.

MCUs assigned to an OCU as a result of a request remain permanently assigned to that OCU until released.

Additional MCUs may be requested by that OCU. Selected MCUs cannot be accessed by other OCUs.

Once one or more MCUs are requested, it is possible to switch between the various available combinations of

MCUs by altering the selection on the OCU.

RELEASE Function

The Release button is used to release the MCU(s) currently selected by an OCU.

An OCU can only release MCUs which it has previously requested. Conversely, MCUs not assigned to a specific

OCU cannot be released by that OCU.

One or multiple MCUs can be released at the same time. The MCU can be set to automatically release.

5.9 Sub Address Capability (SAC)

The SAC optional feature is available for the LRC-L OCU and the MMCU4 or CT24 MCUs.

It allows one OCU to have secure and simultaneous selection of up to four MCUs from a larger number of MCUs.

With this feature, there is no possibility that any two OCUs can attempt to select the same MCU at the same time.

For example, this feature allows the sequential selection of MCUs in a process flow. Keys 1 and 2 might represent

hoist units 1 and 2, Keys 3 and 4 may represent sequential bridges, and the spare keys may represent further

sequential bridges.

Each of the selected MCUs can be enabled or disabled by an associated toggle switch.

There are three versions of SAC defined in the following ways:

• One OCU may select 4 out of 512 MCUs

• One OCU may select 3 out of 4096 MCUs

• One OCU may select 2 out of 262,144 MCUs

SAC TransKeys

The identities of the selected MCUs are input by a secure, red, RF TransKey inserted into a dual holder on the left

and right faces of the OCU. An OCU has the option of two or four slots and either two or four associated toggle

switches.

Two storage slots on the rail can hold unused keys.


18


Sub Address Key Read Status

The sub address key read status is shown on both the status LEDs and the optional LCD (if fitted to the OCU).

Figure 8: SAC LED Status Indications

• Empty Socket: The corresponding LED remains off

• Successful Reading: The corresponding LED flashes green

• Reading Failure: The corresponding LED flashes red

OCUs equipped with an LCD will display the actual sub addresses being read and the current selection status on

lines 2 and 3.

Figure 9: SAC LCD Status Indications

Deselected MCUs (toggle switch OFF) are shown in normal text (black text on a white background).

Selected MCUs (toggle switch ON) are shown in inverted text (white text on a black background).

The MCU may store up to five sub addresses and locks onto the first valid sub address found. This feature allows

one MCU to be able to respond to a maintenance or spare TransKey (in the event of loss of the primary sub

address TransKey) without ever having to duplicate a TransKey sub address on one site. For example, an MCU

may be programmed to respond to SA, 1, 101, 201, 301, 401, 501.

The Sub Addresses are stored in the MCU primary TransKey.


19


Sub Addressing Operational Procedure

1. Ensure the battery has sufficient charge.

2. Verify the OCU is in good condition.

3. Select the required Sub Address TransKeys to match the machines to be controlled. Insert these

TransKeys into the TransKey retainers on the left and right faces of the OCU.

4. Switch the sub address selection switches to the OFF positions.

5. Ensure the control levers are in the neutral position; controls in the off-neutral position will prevent

system start.

6. Ensure the E-Stop switch is released.

7. Ensure the Key/ON/OFF switch is turned ON.

8. The status LED should now flash green; however, if D-TDMA is in use, the status LED gives two

rapid orange flashes every second until the OCU finds and locks onto a free TDMA slot. Usually, this

takes less than a few seconds. The LED flashes green afterwards. If the status LED is flashing red or

not flashing at all, refer to Section 9: Troubleshooting.

9. Press and hold the reset button until all the machines reset as indicated by their individual status

lamps (a visible lamp positioned on the machine that indicates it is powered and reset, ready for use).

This can take up to approximately 5 seconds.

10. Switch on each of the sub address selection switches one at a time and test a basic function (such as

Horn) to ensure the required and expected machine is being commanded. When this is complete and

all machines verified, the required machine selection can be made and operation commenced.

Deselection of any machine is possible at any time by switching off the control toggle switch associated with that

sub address.

Removing any sub address TransKey disables that machine within five seconds. An alternate key could be

inserted without switching off the OCU, but the reset switch would need to be pressed again to capture that

machine, after which it should once again be verified that the correct machine has been activated.

5.10 D-TDMA

TDMA is an optional feature that allows many systems to operate on the same frequency, either to minimize the

number of RF licenses required on a large site or to make it possible to implement a system that requires many

OCUs to be on the same frequency at the same time.

It is possible to have MCUs use both TDMA and frequency scanning when implementing a large or complex

system comprising many MCUs.

As more TDMA slots allocate to a frequency, the system response to a switch change becomes slower, so a

balance between allocated TDMA slots and required response times is needed.

When operating D-TDMA and after switching on the OCU, the status LED gives two rapid orange flashes every

second until the OCU has found and locks onto a free TDMA slot. This typically takes less than a few seconds

after which it should flash green.

If an optional LCD display is fitted, this will also give additional TDMA status indication, as seen in the following

figure.

Figure 10: D-TDMA LCD Status Indications

At power-up, the first telegram transmission is declared “Slot #1”. Its index would be set to “C” (for Current) and it

displays on the left side of LCD screen. This slot timing would be set as reference and kept in memory as long as

the radio is transmitting telegrams. All other slots are shown following this reference point; free slots are shown as

normal text (black text on a white background) and occupied slots are shown as inverted text (white text on a

black background).

Note that all OCUs are running asynchronously, so slot 1 on one OCU may not be the same as slot 1 on any

other OCU.

21



5.11 Frequency Scanning

Frequency Scanning is an optional feature that allows one MCU to scan multiple frequencies (the current limit is

12). This feature allows one MCU to operate from any one out of many different OCUs transmitting on different

frequencies.

Frequency scanning may be combined with TDMA, and MAC or SAC.

This feature is likely to be used where TDMA is not needed, or where the number of OCUs on air exceeds the

TDMA allocation per frequency.

This feature is available on all MCUs.

For example, an MCU running frequency scanning of eight frequencies each running with OCUs running TDMA

with seven slots could seek and lock onto a valid address from 56 (= 8 X 7) OCUs.

5.12 Talkback and LCD Display Resolution

Talkback is an optional feature.

Talkback may be directed to LEDs, the buzzer, and (if fitted) the LCD display and backlighting as well.

For LRC-M and LRC-L OCUs fitted with the optional LCD display, this display has a resolution of 128 x 64 pixels

and is divided into eight lines. The first and last lines are reserved for system status messages, and the remaining

six lines may be used by the user for talkback information as text, graphics, or both.

Customers have the option of having the talkback configured for them, or the flexibility of a tool to be able to

program and customize the talkback themselves.

7. RF Channel Change

If your system is configured to use one of the standard license exempt frequency bands, you will have the option

of selecting a new frequency; this may be required in order to ensure interference-free operation under some

circumstances. Changing the RF channel can become necessary due to interference or if a RF channel is already

in use by another system. The RF channel can be changed either by reprogramming the TransKey (external

programming) or by using the RF channel selection feature of the OCU unit as described below.

Note: The features described in this section are available with standard OCUs furnished with a key switch and

horn push-button. Should these control elements not be available, these features may not function in

part or entirely.

7.1 Working Principle

The operating RF channel of the OCU can be changed using the push buttons in the LED/push button panel. For

this, first bring the OCU into Programming Mode as below. The respective RF channels are displayed by the four

LEDs located to the left and right of the STATUS LED. Each RF channel is assigned a specific color code, shown

in the 'RF Channel Tables'.

Figure 16: LED / Pushbutton Panel

7.2 Activating the Programming Mode

Before the RF channel can change, the OCU must be brought into Programming Mode.

1. With the OCU turned off, hold the Horn push-button down and turn the unit on by turning the key

switch.

2. Hold the Horn push-button for approximately 5 seconds until the Status LED changes from

permanent red to fast blinking red.

3. Release the Horn push-button within 3 seconds.

4. The OCU is now in Programming Mode. The currently selected RF channel is indicated via the four

LEDs on the panel.


26


7.3 Changing the RF Channel

1. Bring the OCU unit into Programming Mode. If it is already in Programming Mode, continue with the

next step.

2. The actual RF Channel is displayed by the LEDs; see the RF Channel Tables.

3. Select the desired RF Channel by pressing the buttons. For fast hold, depress for more than two seconds.

4. Select and save the RF Channel with the Enter button .

5. The Status LED changes from blinking red to continuous red.

6. Turn the OCU off with the key switch.

7.4 MCU Synchronization to New RF Channel

The OCU features an automatic RF channel synchronization. It automatically finds its corresponding OCU and

adjusts its RF channel to the new channel.

Note: After the first OCU activation following a RF channel change, it can take up to one minute before the

MCU adjusts itself to the new RF channel and is ready for operation.

7.5 Reactivating the TransKey RF Channel

The RF channel programmed by the factory remains stored in the TransKey and can be reactivated if required.

1. Bring the OCU into Programming Mode. If it is already in Programming Mode, continue to the next

step.

2. Holding both and pressing reactivates the RF Channel stored in the TransKey.

3. The STATUS LED changes from blinking red to permanent red. All other LEDs are off.

4. In order to take the OCU into operation, turn it off and on again.

5. It now transmits on the RF channel stored in the TransKey.

7.6 Indication of the Interference Field Strength

This is a helpful feature to determine whether other systems are transmitting on the currently selected RF

channel. The level of interference, i.e., the field strength, of such systems can be indicated. The interference field

strength is displayed via the Status LED in combination with the internal acoustic buzzer signal.

In the event that there is interference on the selected RF channel, it is recommended that a different, free RF

channel is selected.

Note: This feature is not available for the 869 MHz frequency band.

1. Bring the OCU into Programming Mode. If it is already in programming mode, continue to the next

step.

2. Briefly press the HORN push-button.

3. If there is any interference, the severity is indicated by a combination of a STATUS LED and an

internal buzzer sound for three seconds. There are three levels of interference, as shown in the

following table.

4. Should there be no interference, exit the programming mode by turning the unit off.

Table 4: RF Channel Status LED indication

Status LED Buzzer Interference Connective Action

Green No sound Low None required

Orange No sound Medium If possible, change the RF channel

Red Sounding High Change the RF channel

Note: The field strength received from other OCUs should be as low as possible in order to avoid possible

interference of the radio path between the OCU and the MCU.

7.7 Automatic RF Channel Selection Feature

The OCU has a feature that allows automatic scanning of all RF channels in the respective frequency range for

interference. During the scan process, the OCU performs field strength measurements of each individual channel

and creates an internal, virtual channel proposal list. Upon completion of the scan process, the RF channel with

the lowest interference field strength is displayed (on the four LEDs) as the recommended channel. Either this

recommended RF channel can be accepted, or the next channel on the list of proposed channels can be

selected.

Note: This function is not available for the 869 MHz frequency band.

1. Bring the OCU into Programming Mode. If it is already in programming mode continue to the next

step.

2. Press the HORN push-button for five seconds until a sound is audible, and then release it.

3. RF Band scanning starts, indicated by the STATUS LED changing from red to blinking orange.

4. The RF channel LEDs change according to the RF Channel Tables.

5. Once the scanning process is completed and a sound is audible, the STATUS LED changes to

blinking green.

6. The RF channel with the lowest interference is displayed. It can be accepted and saved by pressing

the Enter button , or an alternative option can be selected as shown below.

7. STATUS LED changes from blinking green to continuous red.

8. Turn off the OCU.
