IMET - M550 ALL1-EN 3/53

INTRODUCTION

The M550 family is the result of IMET’s many years’ experience in the production of radio remote
controls. IMET radio remote controls are advanced instruments designed and built using state-of-the­art technology.

IMET M550 radio remote controls are available in a large number of versions for any application. They
are easy to install and they become an integral part of any machine that can be operated by remote
control.

IMET radio remote controls come in many
versions: simple units with single transmission
and digital controls (ON/OFF), or more complex
units with digital/analog controls, CAN-bus and
dual transmission (data-feedback option).

The practical, ergonomic control panel lets you
manage all machine functions and perform the
most difficult operations from a safe position.

The units are easily identified by the ID code
printed on the nameplate affixed to every unit.
The meaning of the ID codes is shown in the
tables on pages 5 and 6.

The casings are made of shockproof plastic to
guarantee complete functionality even in the
toughest operation conditions.

M550 portable transmitters are equipped with a
removable, rechargeable sealed battery,
ensuring continuous operation over long work
shifts even in extreme environmental conditions.

The frequency synthesis radio section (PLL) lets
you change the frequency of the transmission
channel directly on the control panel.

Continuous, encoded radio transmission is used:
the receivers are designed to recognize control
signals coming from transmitters having the
same ID code. Signals coming from other
transmitters are ignored. . In the presence of
interference, bad reception or interruption of the
radio signal, the receiver automatically puts itself
in stop status, that involves opening the E-STOP
circuit (clause 9.2.7.3 EN 60204-32).

Every radio remote control is designed and built in conformity with the European Directives and with
the relevant standards and can be used to set up a wireless control station complying with the strictest
safety requirements.

2. CONVENTIONS USED IN THIS MANUAL

Warning: This symbol indicates instructions to be strictly followed for the radio remote control to

work properly.

Danger: This symbol indicates important information on avoiding dangerous situations when using

the radio remote control.

Note: This symbols indicates useful suggestions for the proper use of the radio remote control.

3. CAUTION

READ THE INSTRUCTIONS CAREFULLY BEFORE INSTALLING THE RADIO REMOTE
CONTROL! FAILURE TO APPLY ANY OF THE PROCEDURES DESCRIBED IN THIS MANUAL
MAY LEAD TO INJURIES TO PERSONS OR DAMAGES TO PROPERTY.

NO PART OF THE RADIO REMOTE CONTROL SHOULD BE USED AS A SPARE PART FOR
OTHER RADIO REMOTE CONTROLS.

Follow the local laws on safety and workplace accident prevention. All the regulations on using radio
remote controls for industrial machinery MUST BE OBSERVED AT ALL TIMES.

IMET accepts no responsibility for the unlawful use of the radio remote control.

3.1. Risk analysis

It is necessary to evaluate the risks, in order to establish the safety and health safeguard requisites
concerning the machine with radio remote control use. A risk analysis must be carried out when
deciding whether an application can be radio controlled. It should be carried out by qualified
personnel, who assume all the relevant responsibilities.

IMET accepts no responsibility for failure to carry out a proper risk analysis.

A possible loss of communication between the transmitter and receiver, caused by disturbances or
electromagnetic interferences, has to automatically block the radio command (clause 9.2.7.3 EN
60204-32). This implies a new procedure of starting the machine, so this blockage should be
considered a foreseen condition

3.2. Applications

The most common radio remote control applications regard lifting or carrying apparatus such as tower
cranes, bridge cranes, truck cranes and concrete pumps. Other applications are possible provided the
following conditions are observed.

Do not use the radio remote control in environmental and electrical conditions other than those
specified in Chap. 9. Do not use the radio remote control in environments that are required to be
explosion-proof. The radio remote control should be installed by qualified personnel following the local
regulations.

Keep this manual and the warranty certificate (filled out in every part) in a safe place.

IMET - M550 ALL1-EN 7/53

4. PREVENTIVE MAINTENANCE

Before performing any maintenance operation, turn off the power to both the receiving unit
and the machine and remove the battery from the transmitter.

• Do not expose to heat sources

• Avoid prolonged exposure to direct sunlight

• Do not wash with water under pressure or dip the device in water

• Avoid contact with oil or solvents

• If the device has been opened for any reason, make sure all the seals and gaskets are in place

when closing

To keep you radio remote control in good working order, regularly clean it using a brush and a damp
cloth. Do not use alcohol or solvents: they might damage the components and the casing.

4.1. Routine maintenance to be carried out by operator

Periodically clean the outside of the receiving and transmitting units. Dirt deposits can hinder the
functioning of buttons, toggle switches and manipulators.

Apply special care to the STOP button, keeping it clean and making sure it works with no difficulty.
Remove any traces of oxidation from the battery contacts.
Check the casing and the components for cracks or apparent damages.
All rubber parts, buttons, seals and gaskets should show no sign of tearing.
Damaged components should be immediately replaced to prevent humidity or dirt from penetrating

and jeopardizing the safe operation of the radio remote control.

4.2. Maintenance and internal checks

After every year of use we recommend carrying out a general inspection on the radio remote control
(to be performed by qualified personnel).

Open the housings of the transmitting and receiving units and make sure:

• that the gaskets are in order

• that the cable clamps are efficient

• that the connection terminal screws and the connector couplings are tight

• that the electronic boards are securely fastened

• that the fastening screws of all components are tight

Although IP65 units are hermetically sealed, dust and humidity may accumulate over time when
working in particular conditions. Carefully remove any foreign matter.

When closing the transmitting unit, apply special care to the casing’s sealing, in order to prevent the
infiltration of humidity.

Power on the device, being careful not to touch any live parts in the receiving unit, and perform the
following tests:

• Check the functioning of all the controls.

• Verify that the STOP circuit intervened correctly. By pressing the STOP button, during operation,

relay contacts A and B, of the E-STOP circuit must be opened

• Any broken parts must be replaced with original s pare parts, in order to keep the characteristics of
the radio remote control unchanged. See list of parts that can be replaced in Chapter 11

5.2. Connecting the receiver

Do not perform any operation until the equipment is powered off.
The power supply for the radio remote control should be located downstream from the machine’s main

switch.

Connecting to the distribution network directly is prohibited. The network disconnecting
switch foreseen for the distribution network must be equipped w ith a device protecting from
unauthorised closing (padlock

The connection between the receiving unit and the machine should always be REMOVABLE

. If the
connection is made directly on the terminal board inside the machine, a multipolar connector should
be used so that the receiver can be disconnected and the original wired controls restored at any time.

The wire connections between the receiving unit and the machine should respect Standard EN60204.
The wires must have a cross-section of at least 0.75 mm

2

and must be self-extinguishing.
If possible use ferrules for conductor ends, and make sure that the terminals are fastened tightly.
Consult the transmitting unit controls diagram (Annex A) and the receiving unit wiring diagram to

identify the equivalent actuators in the two units.
Be sure to note the supply voltage when connecting the receiving unit.
In versions H-AC and L-AC, the fuse current must be adjusted to the supply voltage.

After installing, test the radio remote control and the machine to make sure they work as
expected. In addition, it is very important to make sure that the STOP circuit works properly.
Pressing the STOP button during normal operation should make the contacts of relays A and B
in the E-STOP circuit open.

Lastly, fill in the sheet showing the connection diagram between the receiving unit and the machine
and write down the date of installation in the box on page 47 of this manual.

5.2.1. Installing the external antenna

A properly installed antenna is essential for a good operating range. Install the antenna outside at the
highest and most visible point, far from metal structures. Use a tuned antenna only, and connect it to the
receiver using an RG58 coaxial cable (impedance 50Ω). For M550S M8 and M550D M8 type
transmitters only use the antennas supplied by IMET, other types of antenna must be approved in
conformity to the ETSI EN 300 200-2 standard

5.2.2. STOP (E-STOP)

Connect the contact of the E-STOP circuit so that it commands the coil of the machine’s main line
contactor, and remember that the maximum allowable current is 5A.

Attention: The E-STOP circuit has been designed for category 4 UNI EN 954-1 standard and/or

PLe according to the ISO13849-1 standard. In order to keep this safety category, the relays
must be connected in series (pre-cable standard configuration by IMET) or in parallel ONLY to
manage interruption of the main power supply line (See Example 2).

5.2.3. Safety STOP (S-STOP)

The Safety Stop is an additional safety function. It consists in relay inside the receiver monitored by
the RX logic that can be associated with the commands sent by the transmitter and which in case of
problems automatically stops the receiver, as shown by the status LEDs.

Example 1 (in series to control commands): The Safety Stop introduces a redundancy which activates
the safety function in case the control command relays fail to open.

Example 2 (operating the bypass valve): The Safety Stop can command the drain valve in a hydraulic
machine so that the machine is powered only when a control command is given.

The Safety Stop must not be associated with the bistable selection controls

The risk analysis and safety class are based on Standard UNI EN 954-1 and ISO 13849-1 . The safety
class of each control is shown in Annex B. Take good notice of the maximum currents allowable on
the relay contacts (see Chap. 10).
