INTRODUCTION
After a decade of success and of satisfaction for IMET customers, the M550 series passes the baton
to the new M880 family. IMET designs and manufactures industrial safety radio remote controls since
1988.
The M880 series features advanced radio remote controls with new technical features that facilitate
use by giving great flexibility to the user.
The IMET range of solutions is vast, but it continues to evolve
depending on the technology trends of the modern world. In
fact, it is surprising how today, new applications in every
imaginable field of production see the light. Any existing
machinery or of new conception, could have the need, on the
user side, to make it radio-remote controllable.
M880 Transmitters
The advantages of the use of the remote control are: safety, first and
foremost, to prevent the potential risks of job; comfort, and not least,
the excellent cost / benefit ratio.
Consider, among other things, the best point of view and the mobility
which gives the radio control. IMET has developed over the years,
reliable remote controls, which allow the operator to have a total
control of the work situation. Furthermore, IMET radio remote controls
take into account the ergonomics, the size and the weight, to ensure
that the user can work in a comfortable and safe way.
L Receiver
IMET radio remote controls can be used in various applications in the
fields of mobile machines and the industry. Applications vary from the
simplest, with the few digital ON/OFF controls, to the most complex,
with many mixed commands, digital and analog, plus data-feedback.
They perfectly interface themselves, of course, with modern industrial
automation systems and PLCs with the CANopen and CANbus,
protocols, etc.
IMET radio remote controls have an easily interpretable identification
code, to allow their immediate recognition.
The housings are made of impact resistant plastic to withstand the
toughest conditions of use, keeping intact in time the reliability and
functionality.
Rechargeable batteries are hermetic and removable and ensure
continuous operation for long shifts, or even under severe weather
conditions.
H Receiver
The M880 series features an automatic frequency change, also. This property allows to position
oneself on free channels, thus avoiding interference with other devices in the vicinity. The operator can
decide, in any case, to set the transmission on a fixed channel, as it is for the M550 series.
Each transmitter is designed and manufactured in compliance with the directives and the sectorial
European standards and meets the highest safety levels, such as the PLe for the STOP circuit. The
radio transmission is continuous and encoded, where each receiver recognizes only those commands
coming from its matched transmitter, thus avoiding unwanted activations by other transmitters in the
area.

6. 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 the device with water under pressure or dip it 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
When cleaning it, do not use alcohol or solvents, as they might damage the components and the
housing.
6.1. Routine maintenance to be carried out by the operator
Periodically clean the outside of the receiving and transmitting units. Dirt deposits could hinder the
functioning of buttons, toggle switches and manipulators.
Apply special care to the STOP button, by keeping it clean and making sure it works effortless.
Remove any traces of rust 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.
6.2. Maintenance and internal checks
After every year of use, we recommend carrying out a general inspection of 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 good shape
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 intervenes correctly. By pressing the STOP button during operation,
the relay contacts A and B of the E-STOP circuit must open.
Any broken parts must be replaced with original spare parts, in order to keep the characteristics of
the radio remote control unchanged. See the list of parts that can be replaced in Chapter 13.

7.2. 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 it directly to the mains distribution network is prohibited. The mains disconnecting
switch must be equipped with a device to prevent unauthorized closing (padlock). It must be
easily accessible and be attached outside of the equipment. The distance between contacts
must be of at least 3 mm.
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.
Conductors and cables shall be selected so as to be suitable for the existing operating conditions (for
example, voltage, current, protection against electric shock, grouping of cables), as well as external
influences (for example, ambient temperature, presence of water or corrosive substances, mechanical
stresses-including stresses during installation- and fire hazards). When cables are installed on hoisting
machines used in the open air (outside buildings or other protective structures), they shall be suitable
for outdoor use (for example, UV-resistant, adequate temperature range), or be appropriately
protected.
The wire connections between the receiving unit and the machine should respect the Standard
EN60204 and must be stranded. The wires must have a cross-section of at least 0.75 mm2 and less
than 13 mm2 and be self-extinguishing. If the equipment is used with ambient temperature of 70°C the
maximum conductor operating temperature must be greater than 75°C.
Use ferrules for conductor ends, if possible, and make sure that the terminals are fastened tightly.
Consult the transmitting unit control diagram (Annex T) and the receiving unit wiring diagram (Annex
R) to identify the equivalent actuators in both units.
In the HDC version, the receiver is also intended to be electrically powered at a voltage of 24 VAC
50/60 Hz. Connect it to an external source where the dedicated 24 VAC output is separated from
dangerous voltage parts by double or reinforced insulation.
In all receiver versions, the loads connected to the relay board must have a protection against over
currents and overloads.
In the HDC version, the receiver is intended to be electrically powered in the voltage range 11 to 30
Vdc. Connect it to an external source where the dedicated 11-30 Vdc output is protected against
overvoltage and short circuit. The 11-30 Vdc dedicated output external source must be connected to
the main terminal earth protection or separated from the primary circuit by means of a metal screen
connected to the main terminal of the earth protection.
When the receiver type HDC is provided with a metallic connector (mounted on the enclosure), the
device shall be placed in a "service access area" not accessible to the operator, but only by the
service staff (EN 60950-1 4.5.4 Touch temperature limits of metals at 70°C)
Be sure to note the supply voltage when connecting the receiving unit.
In versions HAC and LAC, 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 open the contacts of relays A and B
in the E-STOP circuit.
Lastly, fill-out the sheet showing the connection diagram between the receiving unit and the machine
and write down the date of installation in the document DECLARATION OF CONFORMITY.
12/56 M880 ALL EN 2.7.2.docx
7.3. 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 and far from metal structures. Use a tuned antenna only, and connect it to
the receiver using an RG58 coaxial cable (impedance 50). Only use the antennas supplied by IMET;
other types of antenna must be approved in conformity to the standard ETSI EN 300 200-2.

7.4. 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 with resistive load.
Attention: In order to maintain the safety category (PLe Category 4 according to ISO 13849-1),
the STOP circuit relays must be connected in series (standard IMET pre - wiring configuration),
or else in AC applications, individually connected in series to the phase line and neutral, ONLY
for the mains power interruption (See Example 2). In series to the STOP relay contacts, there
must always be a 5A fuse.
7.5. SAFETY ENABLE (S-ENABLE)
The Safety Enable is an additional safety function. It consists of a relay in the receiver that is
monitored by the RX logic and that can be associated with the commands sent by the transmitter,
which in case of problems, automatically stops the receiver, as shown by the LEDs status.
Example 1 (in series with control commands): The Safety Enable introduces a redundancy, which
activates the safety function in case the control command relays fail to open.
Example 3 (operating the bypass valve): The Safety Enable can command the drain valve in a
hydraulic machine, such that the machine is powered only when a control command is given.
The Safety Enable must not be associated with stable selection commands
The risk analysis and safety class are based on standard ISO 13849-1. Take good notice of the
maximum currents allowed on the relay contacts (see Chap. 12).
