8 - Installation and use recommendations
Experience shows that the functional ef fi ciency 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.
8.1- 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:
AC
PLC input
(Draw resistor R=Vdc/Imin(10mA))
Output on AC relay
(RC circuit )
Receiver output terminal strip
Output on DC relay
(freewheel diode)
