Earth-moving machinery - Safety
requirements for remote operator control systems
1 Scope
This Standard specifies the essential safety requirements for remote operator control systems used on earth-moving machinery as defined in ISO 6165.
It is not applicable to autonomous control systems that enable a machine to work without the assistance of an operator, nor does it apply to the remote control of attachments on non-remote controlled machines.

4 Requirements for remote operator control
4.1 General requirements
4.1.1 Design
The principles of ISO 15998 shall be followed in the design of remote control, safety-related, machine control systems using electronic components.
Remote control systems shall be designed so that all powered movement is prevented for any of the following conditions:
a) the operator controls are not activated;
b) loss of the power supply of the remote control system;
c) loss of the signal between the remote control box and the receiving unit;
d) loss of the machine power supply that interrupts any part of the remote control system;
e) any remote control operation interlock not in place and/or functional.
Re-establishing the power supply or the signal between the remote control box and the receiving unit shall not create unintended hazardous machine motion. Resuming remote controlled operation shall only be possible after an intentional reset of machine operation by the operator.
When hazardous zones of the machine are not visible to the remote control operator, there shall be means for the operator to provide a warning before the engine or machinery is started. Exposed personnel shall be given time to leave the hazardous zone or have the means to prevent the engine or machinery from starting.
4.1.2 Wireless control
Remote control systems shall have a means (indicator light, beacon, audible alarm, etc.) of identifying the corresponding controlled machine prior to the start of the remote operation. The warning device specified in 4.10 may be used.
4.1.3 Wired control
The control cable shall be of sufficient length and flexibility to allow the operator to maintain an operating position outside the hazard zone. Excessive tension on the control cable shall not cause actuation of the controls. Any failure of the control cable or connection shall cause powered machine movement to stop.
4.2 Signal integrity
The signal transmission system shall have an error detection and/or correction system to prevent the machine controls from being actuated by false signals resulting from burst levels of electromagnetic radiation, temporary signal loss, etc. The data communication protocol shall continually verify the integrity of the communication link and of the data being transmitted. If signal integrity cannot be verified, remote controlled powered movement shall stop until signal integrity has been re-established and the operator has performed an intentional reset.
4.3 Operating range (wireless)
The operating range of the remote control shall be sufficient to allow the operator to be outside the hazard zone; this range shall be clearly stated in the operator's manual.
4.4 Remote control box
4.4.1 Design
Machine movement, other than machine stop, shall only be able to be controlled from one remote control box at a time.
By design and the application of ergonomic principles, the remote control box shall minimize restriction of the machine operator's freedom of movement.
The presence of electrical power at the remote control box shall be indicated by an optical device, e.g. LED or panel light.
4.4.2 Operator controls
4.4.2.1 General
Continuously running work function controls (e.g. attachment controls) and float controls may be held in a detent position. Other machine operational controls on the remote control box shall return to their neutral position when the operator releases the control or shall require an alternative sustained operator input control (e.g. hold-to-run).
When the controls are in their neutral or detent position, the resulting machine action shall be the same as when the corresponding controls on the machine, if present, are in their neutral or detent position. Instructions shall be provided in the operator's manual for the approved use of continuously running work function controls.
