operation of rollers with attending operator.
A.3 Terms and definitions
For the purposes of this annex, the following terms and definitions apply.
A.3.1
remote control
portable transmitter and a receiver permanently mounted on the roller
A.3.2
transmitter
steering element with the necessary controls for issuing commands and the transmission element including the part
for modulation
A.3.3
receiver
receiving element including the part for demodulation, the evaluation unit as well as the command-output element
A.3.4
safety distance
minimum distance between the roller and operating personnel necessary to prevent injury
A.4 Safety requirements and measures
A.4.1 All travel movements shall be switched off automatically by the receiver if:
a) the maximum range exceeds 20 m;
b) the distance of the machine to the operator is closer than 2 m;
c) a break in communications between the remote controls and machinery lasting longer than 3 s occurs;
d) the power supply to the transmitter or receiver is interrupted;
e) the travel controls are released.
NOTE If there is an insufficient state of charge concerning the battery of the transmitter, this state should be indicated (e.g.
acoustically or optically) before the function of the equipment is affected in any way (e.g. alteration of the transmission of control
commands).

A.4.2 When a return of power occurs after a power cut affecting the transmitter or receiver, the roller shall not
automatically start to move.
A.4.3 Transmitters and receivers shall be assigned to each other, e.g. on the basis of a code.
NOTE Measures should be taken to ensure that interference with the process of wireless transmission due to external sig-
nals or a combination of several remote control systems with the same transmission frequency does not cause hazardous
movements.
A.4.4 No hazardous movements shall be caused on connection of transmitter or receiver to a power source.
A.4.5 Remote controls shall be constructed to be capable of withstanding any operation stresses and external
influences which may reasonably be expected.
Operating stresses are, for exampl
