SAFETY

1.1

Safety of the Radio Control System

The Radio Control System has been equipped with electronic and mechanical safety devices. Processing control signals sent by

other transmitters is impossible as the transmission codes are totally unique for each system.

1.2

Safety Information

The use of the Radio Control applied to any machinery allows the operator greater freedom of movement within the working area,

improved handling accuracy whilst improving both the efficiency and the safety of the operator. However, all these benefits do require a
certain attention from the operator and the staff in charge of maintenance.

The correct and safe use of the Radio Control requires the operator to visually follow the remote-controlled machine.

It is therefore compulsory that anyone using the transmitting unit stops the Radio Control by pushing the Emergency stop push-

button during the break times.

The maintenance staff should check that the receiver unit is not powered during the control operations, the change of the battery

or the periodic or extraordinary maintenance operations in general.

Each Radio Control should be checked at least once per year. Any repair should be made at authorized centers or centers that

Tecnord has recommended or directly at the Tecnord service and spare parts center. Any use of no-original spare parts or tampering by
non-authorized staff immediately cancels all the warranty rights.

1.3

Authorized Operators

IMPORTANT !

Always verify the operating instructions of your machine in order to be aware of any further important information to be observed.

When placing the transmitter away during the breaks, the user must make sure that no unauthorized people can use it by pushing the

Emergency Stop push-button and locking it in a safe place. In this way, any abusive operations by unauthorized third parties will be
prevented. The user must be able to have access to all of the operating instructions that are necessary for the smooth operation of
the machine to be controlled. The user must also read and be sure to have clearly understood each section of this manual before using
the Radio Control.

1.4

Safety Measures to be taken within the working area

The user should ensure that the working area in which the Radio Control will be used is free from any risks for the movement or

other potential safety risks. For example, the user should verify that the working area is free from any obstacles or dangerous situations
that could jeopardize the possibility of operating in total safety.

1.5

Protection Devices

All of Tecnord’s industrial Radio Controls have been fitted with an Emergency Stop push-button on the control board of the

transmitting unit.

Several other protection devices exist in the Radio Control system which automatically intervene whenever:

There is a radio interference in the working area that affects the frequency range of the Tecnord Radio Remote Control;

The action range of the transmitting unit is exceeded.

In the event of the above the Radio Control immediately activates the Emergency Stop, and interrupts any outgoing signal of the

receiving unit whilst maintaining, whenever possible, continuous and constant radio contact between the transmitter and receiver.

1.6

How to react and behave in case of an Emergency

WARNING

In any Emergency situation, immediately push the red EMERGENCY STOP Push-Button (also called: EMERGENCY

STOP PUSH). Then, follow the instructions in the machine operating manual.

INSTALLATION

WARNING !

Only a qualified and specialized technician should install the receiver of a radio control to the electrical system
of a machine (see par.4, Maintenance) who is acquainted with both the electrical circuit of the machine and the
radio control technical features.

During the entire installation phase both the transmitter and the receiver must be turned off.

All of the regulations on the health of the staff working within the installation area, together with any local
regulations in force, and those on fire prevention must be observed.

TECNORD declines all responsibility, neither does it grant any guarantee whatsoever for any damage caused to
things or persons due to the improper or careless use of this equipment or due to the non-observance of any
regulation or that, which has been indicated in the operating instructions.

3.1

DBX Receiver Unit sample drawing

3.2

Positioning the receiver

WARNING !

When positioning the receiver, check that it is not being screened by large metallic surfaces.

For the Radio Control to operate smoothly, it is necessary that the receiver should be installed in such a position as to allow the

maximum reception of radio waves from the antenna. The metallic parts of the machine to be controlled that surround the receiver

create a barrier that interferes with reception

In most cases, the receiver can be housed on any side of the machine or, if necessary, for installations on vehicles even inside the

glass cabin. It is also necessary to place the receiver where it is accessible and safe to work both for those who carry out the
installation of the electrical connections and for those who will do the future maintenance.

Make sure to keep the display visible to the user in order to ease the diagnostics of the equipment during operations.

Should such an installation be performed on board mobile machinery or on a vehicle, then you should attach rubber bumpers.

These rubber bumpers will prevent strong vibrations from the machine to the receiver.

Outside electrical connections

Outside electrical connections are:

Power Supply

Input / Output connections

For safety reasons it is recommended to install on the controlled machine a supply disconnecting device in order to cut off the

receiver’s power supply when necessary. This supply disconnecting device should comply with the directive EN60947-3, cat. AC-23B or

DC-23B. The following requirements apply to the supply disconnecting device:

- isolate all live conductors of the electrical equipment from the supply and have one OFF and one ON position only, that shall clearly

marked with the “0” and “1” symbols respectively

- have a visible gap or a position indicator which cannot indicate OFF until all contacts are actually open

- have an external operating handle, which shall be easily accessible to the operator, and must be located between 0,6m and 1,9m

above the servicing level. The device must be provided with means permitting it to be locked in the “off” position.

For safety reasons, a fuse of 10A is included in the DBX-RX receiver’s box.

All the connections between the equipment and the power supply must be made with conductors having a diameter of at least

2.5mm.

Each function that is activated on the transmitter unit activates a dedicated output, or a combination of more outputs, on the

receiver unit, depending on the configuration of the machine to be operated.

OPERATION

4.1

The radio transmission and servicing system

Tecnord’s RC-DBX ,RC-PCM and RC-NBM Radio Control Systems allow for the operating machines to be controlled in general by

means of electro-magnetic waves. It is made up of a portable transmitter unit (SHW ,PCJ TX or NBJ-TX) held by the operator and of a
receiver unit (DBX-RX) that is usually installed on the machine to be controlled.

Each function originated from several devices or control actuators of the transmitter is transformed into a serial command that is

coded and transmitted through a high-frequency carrier. The receiver captures the information output from the transmitter, decodes
the messages and sends the controls to the machine by means of electronic power switches controlled by a microprocessor and a
dedicated harness.

The information sent from the transmitter is contained in a message commonly named “telegram”. This telegram consists of an

identifier, a command field and a redundancy field for error control. The identifier, or matching code, contains the identification
elements to match the transmitter with its coupled receiver. The command field contains all the information relevant to the commands
that the machine should carry out. The error control redundancy fields allow the receiver to discard messages that are found modified
by disturbs on the radio link.

As the matching code is unique for each TX/RX pair, each Transmitter can control through radio waves only its coupled Receiver,

which is labeled with the same System Number.

4.2

Use of Batteries

Tecnord’s Radio Control System is equipped with batteries for operating the Transmitter. Rechargeable NiMH batteries are supplied

with the Transmitter unit and guarantee a long operating time.

The working voltage of the transmitter is constantly controlled. Should it fall below a threshold value, the corresponding indication

is activated (green led blinking) each time the transmitter is put into operation. From this moment, the transmitter can continue to
operate, but it is recommended to recharge the batteries as soon as possible. For additional power-saving, a “PowerSave” mode is
implemented (see paragraph 4.8).

Batteries are protected against short –circuit. For additional safety and ease of use, they are located as far as possible from the rest

of the electronics in the Transmitter.

4.3

The battery charger and re-chargeable batteries

The RC-DBX-TU transmitter unit is equipped with a battery charger circuit; therefore it is not necessary to remove the batteries for

the charging operation, and is possible to operate the machine during the battery charging procedure.

In order to charge the batteries, connect the Transmitter to its DBX-RX receiver unit through the battery charger cable supplied

with the equipment. As an option, a different serial cable can be provided, which allows the charge to be carried out while operating
the machine. In order to use the serial cable option, the harness must be provided with an appropriate M12 female connector. The
charging phase for a completely discharged battery can last up to three hours, and it is continously controlled by the microprocessor.
When the battery charger states that charging is complete, it automatically disconnects, therefore avoiding overcharge phenomena that
could reduce batteries life.

WARNING !

Use TECNORD original spare parts only! If not, there is the danger of an explosion. Chemical substances that leak or

parts that detach themselves can cause irreparable damage.

4.4

Control Elements

Tecnord manufactures a family of Industrial Radio Controls suitable for just as many applications. Further more, Industrial Radio

Controls are designed according to the specific requests of the Customer or the User.

Tecnord’s Radio Remote Control Equipment are designed as complete systems for controlling an operating machine’s functions.

Each Radio Control System can be fitted with many different control elements according to the machine to be controlled, as well as
provided with standard controls for its operation, stopping, acoustic warning, start switch, warning led etc.

Push buttons, switches, selectors, joysticks and special control accessories complete the radio control. Their type and number are

features of each “control configuration”.

Configurations “D”, “R”:

up to 6 toggle-switches with 3 positions (1 stable + 2 temporary) for the function’s
selection, 1 proportional trigger available for speed control in the “R” configuration

Configuration “M”:

up to 6 PRS (Proportional Rocker Switches, for DBX) or 7 JLP joysticks (for PCM) for the
control of more functions with proportional actuators

For a better diagnosis of the machine’s operating status, the DBX-RX receiver is equipped with a display on which is possible to

make system information available (see paragraph 8.2).

Visual Check

WARNING !

Always check the sound condition on the transmitter before operating.

Are all the safety devices in the correct position and in good condition?

Are there any broken parts?

Are all of the rubber protections and the actuator covers sound?

Are all of the connecting plugs and cables sound?

WARNING

Never work with a Radio Control which results damaged! Always remove any of the above-mentioned faults before

starting to work!

4.6

Safety Control and Start-up of the Radio Control

WARNING !

Important checks on some of the functions mentioned below are required for the first start-up of the Radio Control!

Verify that the transmitter battery casing on the SHW-TX unit also houses a rechargeable battery and that the battery is
connected.

Release the Emergency Stop Push Button on the Transmitter unit, if pressed. Releasing the Emergency Stop Push Button turns
the TX unit on. In RC-PCM or RC-NBM systems it is necessary to engage the radio control with the appropriate pushbutton.

Now, your Radio Control is ready to work. Activate any function on the transmitter unit and verify whether the machine stops
when the same function is released should you release the switch or re-set the proportional actuator to zero.

Now check that the Emergency Stop function works exactly as described by the manufacturer of the machine by applying the
following procedure:

Start any of the functions of the transmitter, verify that the function is activated by the receiver and keep it running

Push the Emergency push button on the transmitter

Verify that the function carried out stops immediately and that no other functions can be then operated from the
transmitter

Was the safety control successful and does the Emergency Stop function work perfectly?

Now release all the control elements

Release the Emergency stop push button, your radio control is now ready to operate in total safety

WARNING !

Should any fault or problem be noticed during the initial starting, turn the machine off immediately. Never operate

the machine unless the Emergency Stop Button functions properly. Serious danger exists for both people and things
from the non-observance of this extremely important regulation. Any operation not conforming to this basic operating
rule may lead to the loss of both the operating permit and your warranty.

4.7

Functions operation

Two possible types of electronic control exist that can be operated from the Radio Control, the digital and analog also named ON-

OFF and Proportional respectively. The ON-OFF control determines either the activation or deactivation of an output stage within the
receiver when the transmitter activates this control. Usually, these are commands that can be sent from push-buttons, switches,
slelectors or digital joysticks.

The Proportional control is a function determining a variable output in either current or voltage in a way which is directly

proportional to the position of an analog actuator on the transmitter, be it a proportional trigger, a proportional rocker switch (PRS), a
potentiometric joystick or a simple potentiometer. Tecnord manufactures different types of proportional controls for several models of
solenoid valves, servo controls or other devices. The transmission technoclogy remains unchanged, while the proportional output stage
of the receiver is designed for the different requirements of the command to be carried out.

4.8

PowerSave Mode and Out-of-service

The Transmitter is powered on when the Emergency Stop Pushbutton is released. In order to reduce power consumption a

PowerSave Mode is implemented. When the Transmitter is powered by batteries and no function is activated for five minutes the
system goes into a “PowerSave” mode: the led is switched off and the RF module is no longer active. In order to operate it is necessary
to press and then release the Emergency Stop Pushbutton.

When the Transmitter detects a low value on the batteries the led blinks indicating that battery charging is required. When the

battery level is below the threshold for safe operation the system goes out-of-service: the led is switched off and the RF module is no
longer active.

WARNING !

In both PowerSave and Out-of-service modes, the Transmitter is no longer powered on, even if the Emergency Stop

Pushbutton is released, due to electronic switches. Anyway, it is always a good practice to keep the Emergency Stop
Pushbutton pressed when you’re not operating in order to mechanically disconnect the batteries from the circuits.

4.9

Diagnostics

The RC-DBX , RC-PCM ,RC-NBM Radio Control Systems allow diagnostics on both the Transmitter units and the DBX-RX receiver

unit. The details on the system’s diagnostics can be found in chapter 8.

4.10

Operating problems

Repairs and checks following failure of the Radio Control equipment must be carried out according to the instructions below so that

the system maintains all of its original features. In the event of malfunctions, check that the machine provided with Radio Control
operates properly with traditional control systems (such as, for example, cable control, fixed panel etc.).

Verify that in the area you are operating in with your Radio Control no other Radio equipment has started working and is operating

on the same radio frequency. Also verify that you are operating the transmitter with its own coupled receiver.

If the outputs of the receiver unit are not energized when commands have been transmitted and the machine cannot therefore

carry out any operation, then check the state of the receiver’s power supply fuse, check the wiring connections to find out if any of the
wires is not properly connected or is out of its housing or coupling.

The non-operation of an RC-DBX , RC-PCM , RC-NBM system may depend on either the transmitter or the receiver. The table

located in the following paragraph may help in the diagnosis of the most common causes of malfunction.

4.11

Troubleshooting table

Tecnord’s Radio Control Systems implement a microprocessor technology in both the Transmitter and Receiver units. Each system is

subject to a quality assurance test at the manufacturer’s plants before being delivered to the customer. However, should a failure
subsequentely occur, a swift diagnosis is possible and hence a quick reset of the Radio Control through the technical assistance service.

MAINTENANCE

Tecnord’s RC-DBX,RC-PCM,RC-NBM Radio Control Systems does not require any special maintenance. However, some precautions

are necessary in order to ensure that the equipment is both efficient and safe. Each radio control must be checked at least once a year.
The staff in charge of maintenance must check that the receiver is not powered on during the checks and the inspection inside the
transmitter.

Dust and other material from the working environment as well as dirt can deposit on the transmitter and receiver units. Remove it

so that the buttons, joysticks and actuators in general, including the emergency stop push button, are always clean and therefore in
good working order.

Each control unit has been designed so that all that the above causes the least amount of problems possible to the smooth

operation of the Radio Control. However, careful periodical maintenance by the user will certainly prolong its life span.

The inner inspection of the transmitter should be carried out only by trained staff in a dry and dump-free place. As well as removing

all traces of dirt and drying any condensation with warm air, the checking of the connections of the different wires and terminal boards
of interconnections, as well as the dean condition of the electrical contacts of all of the control actuators is also highly recommended.

WARNING!

In the event of the possible oxidation of the electrical contacts, never use any type of anti-oxidant spray or similar

product. Instead, contact your service center to immediately replace these parts. These problems can be caused by the

particular environmental conditions in which the radio control operates. Using chemical products on the actuators
could cause irreparable damage to the mechanical and electronic parts.

The duration and the capacity of the batteries depend on many elements such as the operating temperature, the charging and

discharging cycles, but basically on how often the radio control is used. It is highly recommended to always use the battery charge until
the “low battery” indication aactivates, and to replace it at least every 2 years.

Besides the regular checks on the interconnections and the firm tightening of the terminal boards for the output controls, it is

recommended to check that the seal of the transmitter unit cover is in good condition and that it is watertight. After 2/3 years of
operation, it is suggested to check the smooth operation of the electronic and electro-mechanical parts, their response to commands
and their drop out speed. Special layers of resin-based insulating paint and with anti-oxidant properties protect the electronic parts of
the Radio Control system; hence they do not require any maintenance. It is, however, necessary to check the various interconnections
between the different modules.

DISPOSAL

WARNING !

Avoid environmental pollution.

Electrical devices and their parts are dangerous waste. This specially applies to batteries and rechargeable accumulators. Engage a

specialized company for their disposal.

SYSTEM DIAGNOSTICS AND CONFIGURATION

8.1

Transmitter’s Diagnostics

Diagnistic on the Transmitter unit is carried out by means of:

a buzzer

a green led

8.1.1

Buzzer

Indications in Radio Mode:

The buzzer provides the following indications:

one short beep when the Transmitter is powered on, i.e. when the Emergency Stop Pushbutton is released;

four short beeps when the Transmitter enters PowerSave mode or goes out of service due to a low battery voltage.

Indications in Cable Mode:

The buzzer provides the following indications:

one short beep when the Transmitter is powered on, i.e. when the Battery Charger Cable is connected to the unit.

8.1.2

Green Led

Indications in Radio Mode:

The led provides the following indications:

led on while the Transmitter is powered on, i.e. when the Emergency Stop Pushbutton is released, and the battery level is
correct for safe operation;

led continously blinking while the Transmitter is powered on, i.e. when the Emergency Stop Pushbutton is released, and
the battery level is low;

led off while the Transmitter is in PowerSave mode or out of service because of an insufficient battery level, or when the
unit is powered off, i.e. when the Emergency Stop Pushbutton is pressed.

Indications in Cable Mode:

The led provides the following indications:

led intermittently blinking (two blinks followed by a pause) indicates that the battery charger is active;

led on indicates that the Transmitter is powered on (i.e. the cable hase been connected) and is ready for operation;
during battery charging , it indicates that a function is active;

led off indicates that the Transmitter is not charging the battery and the emergency pushbutton is pressed.

Note:

When the cable is connected the Transmitter performs some battery checks for about 3 seconds. After that time battery charging is

automatically started when no faults are detected.

8.2

8.3

Calibration Menu

This paragraph is applicable only to systems that implement a proportional current output. The calibration of the parameters of the

proportional output is carried out using the two Pushbuttons (Blue Key and Yellow Key) integrated in the receiver’s electronics, shown in
the figure below.

DBX-RX RECEIVER WITH TWO PUSHBUTTONS

8.3.1

Calibration parameters for DBR systems

Instructions for the Calibration Procedure:

Keep the Receiver’s electronics outside its enclosure in order to access the two pushbuttons: Blue Key (B-KEY) and Yellow Key (Y-
KEY).

Press simultaneously the Blue and Yellow keys for at least three seconds, until the dot on the right digit turns on and the value of
the configured minimum current I

MIN

(in mA) is displayed. Release the keys in order to go on with the calibration procedure.

The menu allows four calibrations, in order: minimum current, maximum current, acceleration time ramp, deceleration time ramp.
In order to switch from one calibration to the next, press simultaneously the Blue and Yellow keys.

In the calibration menu the display dots give information about which parameter is currently being configured in the following way:

Setup of the minimum current I

MIN

(in mA)

Example: “I

MIN

= 410 mA”.

Setup of the maximum current I

MAX

(in mA)

Example: “I

MAX

= 610 mA”.

Setup of the acceleration time ramp

(from 1 to 100 steps of 50ms each)

Example: “acceleration time ramp 500ms”.

(10 x 50ms = 500ms)

Setup of the deceleration time ramp

(from 1 to 100 steps of 50ms each)

Example: “deceleration time ramp 500ms”.

(10 x 50ms = 500ms)

In order to change the configured value it is necessary to activate a movement and operate with the Blue and Yellow keys in the

following way:

press the B-KEY to increase the configured value of one step (fine calibration); keeping the B-KEY pressed causes a rapid
increase of the configured value (coarse calibration)

press the Y-KEY to decrease the configured value of one step (fine calibration); keeping the Y-KEY pressed causes a rapid
decrease of the configured value (coarse calibration)

When the movement is deactivated, the new values are stored in the non-volatile memory of the DBX-RX Receiver.

The only way to exit from this menu is a new power-on of the Receiver (i.e. disconnecting the power supply from the receiver).

8.3.2

Calibration parameters for DBM / PCM / NBM systems

Instructions for the Calibration Procedure:

Keep the Receiver’s electronics outside its enclosure in order to access the two pushbuttons: Blue Key (B-KEY) and Yellow Key (Y-
KEY).

Press simultaneously the Blue and Yellow keys for at least three seconds, until the dot on the display’s right digit turns on. When
only one function is active, the display shows the current value of the minimum voltage for the active function, otherwise three
dashes are displayed. Release the keys in order to go on with the calibration procedure.

The menu allows four calibrations, in order: minimum voltage, maximum voltage, acceleration time ramp, deceleration time ramp.
Different values can be assigned to each parameter for every semi-function: just keep the semi-function active and adjust the
parameter’s value with the keys. In order to switch from one calibration parameters to the next, press simultaneously
the Blue and Yellow keys.

In the calibration menu the display dots give information about which parameter is currently being configured in the following way:

Setup of the minimum voltage V

MIN

Example: “V

MIN

= 2.58V”.

In order to provide a better understanding of the display, all the voltage values
related to the “B” semi-functions are reverted with respect to the real value of

the output. The real output voltage is:

5V – (displayed value)

. With this trick

the operator sees a value that increases when he is increasing the minimum
speed of the function.

E.g. 258 corresponde to a Vmin of 5 – 2.58 = 2.42V

Setup of the maximum voltage V

MAX

Example: “V

MAX

= 4.10V”.

In order to provide a better understanding of the display, all the voltage values
related to the “B” semi-functions are reverted with respect to the real value of
the output. The real output voltage is:

5V – (displayed value)

. With this trick

the operator sees a value that increases when he is increasing the maximum
speed of the function.
E.g. 410 corresponde to a Vmin of 5 – 4.1 = 0.9V

Setup of the acceleration time ramp

(from 1 to 100 steps of 50ms each)

Example: “acceleration time ramp 500ms”.

(10 x 50ms = 500ms)

Setup of the deceleration time ramp

(from 1 to 100 steps of 50ms each)

Example: “deceleration time ramp 500ms”.

(10 x 50ms = 500ms)

In order to change the configured value it is necessary to activate a movement and operate with the Blue and Yellow keys in the

following way:

press the B-KEY to increase the configured value of one step (fine calibration); keeping the B-KEY pressed causes a rapid
increase of the configured value (coarse calibration)

press the Y-KEY to decrease the configured value of one step (fine calibration); keeping the Y-KEY pressed causes a rapid
decrease of the configured value (coarse calibration)

When the movement is deactivated, the new values are stored in the non-volatile memory of the Receiver.

The only way to exit from this menu is a new power-on of the Receiver (i.e. disconnecting the power supply from the receiver).

RC-PCM systems allow to select between two speed sets (normal and reduced working speed), allowing to

independently adjust each parameter of every semi-function in every single speed set. Just select in the Transmitter

the working speed set, activate the function and proceed as described above.

Zero Voltage Adjustment

A special procedure allows to adjust the Zero Voltage, i.e. the voltage that is output when the PRS or JLP joysticks are in their zero

position. This fine adjustment is usually not necessary because the dead band of the controlled equipment allows small differences
between the ideal voltage and the real output signal in the zero position. Anyway it is possible to set a different zero output voltage for
every function with the following procedure:

Keep the Receiver electronics outside its enclosure in order to access the two pushbuttons: Blue Key (B-KEY) and Yellow Key (Y-

KEY).

Press simultaneously the Blue and Yellow keys for about ten seconds, then bypassing the calibration menu, until the dot on the
display’s right digit starts flashing. The current value of the zero voltage for function 1 is displayed.

The menu allows to set the zero voltage in sequence for all the implemented functions. In order to switch from one function
to the next, press simultaneously the Blue and Yellow keys.

In the calibration menu the display dots give information about which parameter is currently being configured in the following way:

Example: V

ZERO

(F1) = 2.51V (dot blinking)

Example: V

ZERO

(F2) = 2.51V (dot blinking)

Example: V

ZERO

(F3) = 2.51V (dot blinking)

Example: V

System Menu (for trained staff only)

The System Menu allows basic configurations of the RC-DBX , RC-PCM and RC-NBM systems; depending on the system, the

configuration process involves different steps, which are organized as submenus.

For RC-DBD/DBR systems the sequence of submenus is:

Proportional Trigger Acquisition (only useful for DBR, only available with the Service Cable connected).

Optional Function Setup.

System Type Setup

For RC-DBM/PCM/NBM systems the sequence of submenus is:

EV9 (venting) safety valve mode of operation.

EV49 (safety valve) mode of operation.

Optional Function Setup.

Output Range Setup

Each of the these procedures is outlined in the following paragraphs.

TECNORD

RC-DBX/PCM/NBM

Use and Maintenance Manual

Page

22/23

Instructions for the system menu setup:

Disconnect the power supply from the receiver unit.

Keep the Receiver’s electronics outside its enclosure in order to access the two pushbuttons: Blue Key (B-KEY) and Yellow Key (Y-
KEY).

Keeping both pushbuttons (B-KEY and Y-KEY) pressed, power the receiver on. After the initialization phase, the unit enters
the System Menu.

Release the B_KEY and the Y_KEY.

Keep the B_KEY and the Y_KEY pressed for about 5 seconds until the DBX-RX switches to the next submenu, then release both
keys.

Repeat step 5 until you reach the submenu where you need to operate.

In order to switch from one Setting to the next, press one of the pushbuttons: the B-KEY scrolls forwards, the Y-KEY scrolls
backwards. In order to acquire the proportional trigger, act as described in paragraph 8.4.1.

When the procedure is completed, turn the power supply off in order to end the System Configuration, or press both B-KEY and Y-

KEY simultaneously for about 5 seconds in order to switch to the next submenu.

Troubleshooting

When, after power-on, the display of the DBX-RX shows the indication “

_On

”, the unit has not entered the System Menu. Power

the Receiver off and repeat the procedure keeping both keys pressed until the unit has entered the System Menu.

8.4.1

Proportional Trigger Acquisition

This paragraph is applicable only to systems that implement a proportional trigger. Connect the Transmitter to the Receiver through

the service cable in order to carry out the proportional trigger’s acquisition.

The Proportional Trigger acquisition is necessary only when the Transmitter unit has been

replaced. This procedure ensures that the proportional parameters previously stored in the

receiver’s memory are maintained.

When entering the Proportional Trigger Acquisition submenu, a code is displayed, which represents the reading of the proportional

trigger, and the receiver is ready for the self-calibration procedure. follow these steps:

Activate a movement: the receiver will not activate any of the outputs, but it will start the self-calibration acquiring the
proportional trigger’s reading.

Keeping the movement active, push the proportional trigger to its maximum value and release it several times; during this phase
the displayed code varies together with the trigger’s movements.

Release the proportional trigger and deactivate the movement; the receiver stores the trigger’s characteristics in its non-volatile
memory.

Troubleshooting

When, after having completed steps 1 to 4, the display shows the indication “

Ad.0

”, the DBX-RX is not receiving any calibration

message from the Transmitter:

Check that the two units are connected properly through the Service Cable.

When, after having completed steps 1 to 4, the display shows the indication “

000

”, the RC-DBX-RU is not receiving any calibration

value for the proportional trigger:

Check that the Emergency Stop Pushbutton is released.
