6- 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.
6.1- 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.
A draw resistor should also be used on the controller inputs.
Examples of protection system to be used :
Output on AC relay
(RC circuit)
Output on DC relay
(freewheel diode)
Draw resistor R
Rmax = Vdc/Imax (10mA)
