4- Installation and use recommendations
Experience shows that the functional efficiency of the system basically depends on
the quality of the installation:
- Interference suppression,
- Choice of operating frequency,
- «Continuous NC or NO» relay operating mode,
- Minimum and maximum current of relay outputs,
- Location of the controlled equipment
- Position of receiver and antenna,
- Quality of wiring of receiver and associated systems,
- Electrical power supply protection.
4.2- Interference suppression
In the event of inductive loads on the receiver relay outputs (contactor coils, solenoid
valves or electro-brakes), interference suppression devices such as capacitors, RC
circuits, diodes, etc. must be placed directly at the terminals of the controlled
components using the shortest possible connections.
4.3- Choice of operating radio frequency
To ensure good operating quality, it is important that the radio channel used be free
throughout the area in which the machine will be controlled.
If several radio remote controls are operating on the same site, frequencies spaced
by at least two radio channels (for example: 5, 7, 9 ...) should be used and, if
necessary, a frequency plan should be drawn up, specifying the various machines
controlled and their working frequency.
4.5- Minimum and maximum current of relay outputs
Be sure not to exceed the minimum and maximum characteristics specified in §
2.3.3 by installing, if necessary, an additional load or intermediate relays (auxiliary
contacts in electrical cabinet for power control, for example).
4.4- «Continuous NC or NO» relay operating mode
If a system is used in continuous mode with the control buttons maintained pressed
and the operator moving about, transmission interruptions can occur due to the
dispersion and propagation of radiowaves which must be taken into account in
accordance with the application.
4.1- «Multifunction» transmitters equipped with
accumulators and charger support (ORCL•) :
When transmitters are equipped with accumulators, please do a load of approximately
3 hours before a first use.
