5.3.2 Conditions for intervention in « manual control » mode
Safety condition in this intervention mode
This mode satisfies the requirements of standard NF EN12100-2 §4.11.8 « Guidelines relative to manual control ».
This mode is possible insofar as control of the movement using the control buttons associated to action on the handle
trigger is sufficient to stop the equipment if necessary.
The « manual » intervention mode is only acceptable provided:
- The risk assessment shows that injury to the intervening technician can be avoided in the event of an
immediate danger.
- The risk assessment shows that the time required to stop the equipment by releasing or clenching the trigger
is sufficiently short to prevent placing the intervening technician in danger.
- An emergency shutdown of the equipment by clenching or release of the enabling handle trigger does not
produce any additional dangerous condition.
Conditions for use of product in « manual control » intervention mode
- The equipment must be stopped from the supervision station or by opening an access gate.
- The enabling handle must be removed from its charger. The « handle withdrawn » information is accessible
on output 17 of the receiver (active at the high state).
- To ensure the « manual controls » on the equipment, the operator must actuate the trigger to the active
position, and use the four control buttons to generate a command.
- So long as the handle is not set down on it charger (operator has not withdrawn from intervention area), the
equipment will not be able to operate again in automatic mode.
- The « manual control » intervention mode is possible in « 4 control buttons » mode and in « function
selection » mode.
- The « manual control » intervention mode does not allow the receiver to manage access to a machine area.
