2 Risk assessment
As required standards ISO 12100 and ISO 14121, all machines must undergo
risk assessment. It is therefore necessary to evaluate, within the limits of this as-
sessment, if the machine can be radio remote controlled.
The radio remote control can only be used if this assessment gives positive re-
sults.
2.1 Risk assessment for radio remote controlled machines
All warnings listed in this manual must also be taken into account during risk as-
sessment and when setting out protection measures for the controlled machine.
When carrying out risk assessment for the machine or for the system where the
radio remote control is installed, the following must be considered:
- some machines cannot be radio remote controlled by Dynamic series radio re-
mote controls (see paragraph 1.1)
- the radio link between the two units may be interrupted due to persistent dis-
turbance or interference.
Whenever the radio link is interrupted (i.e. due to active stop, passive stop, low
battery, automatic switch off, receiving unit not powered):
- all outputs in the receiving unit are disabled (if this generates a hazardous sit-
uation, it is necessary that the corresponding commands on the machine are
kept active)
- it is not possible to enable or disable the machine commands until the radio
remote control is started up again.
Due to the characteristics of radio propagation (i.e.: EM interference, near out-of-
range condition), a delay up to the "Passive stop time" (see paragraph 1.1) may
occasionally occur from the moment a command in the transmitting unit is re-
leased to the moment its corresponding output in the receiving unit is deactivated.
Those who decide upon the installation of the radio remote control must make
sure that this delay never leads to a dangerous situation in the specific uses.
The transmitting unit housing is manufactured so that it protects the actuators
from unintentional activation, while meeting at the same time the operating
needs, the comfort requirements and law limits.
Assessment shall be made to establish possible additional protection measures
for the actuators (i.e. commands requiring two-hand operation, “dead-man” func-
tion) if particular environments, equipment and working modes could cause acci-
dental bumps to the actuators.
