M880 Transmitters
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.
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.
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.
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. INSTALLING THE RADIO REMOTE CONTROL
We recommend following the instructions below, in order to set up a properly operating radio remote
control system.
The radio remote control should be installed by qualified personnel only.
Install the receiving unit or its antenna (in case of versions with an external antenna) in the line
of sight of the transmitting unit, with
no electromagnetic shielding. To
improve the operating range when
the antenna is integrated, do not
install the unit on metal surfaces, if
possible.
Do not bypass the machine’s safety
systems; follow the manufacturer’s
instructions.
Do not install the receiving unit too high
above the ground (1020 metres). At
these heights the unit may receive local
radio signals that could disturb
transceiving operations.
To prevent water infiltrations, install the receiving unit
vertically, with the cable clamps and any other connections at
the bottom, as shown in the figure.
In case of strong mechanical vibrations, place a rubber shock-absorber between the machine and the
receiver (dampers).
