4.4 Spurious
The receiver is designed to become blocked if there is intense spurious disturbance
arising from galvanic, inductive, or capacitive coupling, thus preventing unwanted
manoeuvres.
As a precautionary measure, it is recommended that spurious-preventing devices
(diodes, capacitors, RC circuits) be fitted at the source of the disturbance. These devices
should be connected directly to the contactor coil terminals, etc. and can be obtained
from the usual contactor suppliers.
If the equipment is installed on a vehicle with a friction power supply, where electric
arcs are produced as a result of defective contact, an RC circuit should be fitted between
each phase and earth.
